Can Venus cast a shadow? With Aug. 12's total solar eclipse — where the moon's dark silhouette is everything — now behind us, it's a good time to test another kind of celestial shadow.

Astronomical folklore has it that the second rock from the sun, Venus, is, after the sun and moon, the third object able to cast a shadow when it's near peak brightness, albeit extremely faint, according to EarthSky.

Is it true? Not in a city, where skylights glow and porch lights blaze, where shadows are mostly thrown by passing cars that appear to become the brightest object in the solar system briefly. Venus does cast a shadow, but the sky must be very dark, transparent and free of any light — apparently.

Timing is everything. Having reached dichotomy — its half-lit phase — on Aug. 12, Venus is currently 49%-lit and waning as it moves closer to Earth, increasing in angular size as it becomes a slim crescent. Cue a surge in brightness, thanks to its reflective clouds and its closeness. Shouldn't it be brightest when it's "full?" No, because it's an inferior planet — i.e., it orbits closer to the sun — so it's fully lit only when it's on the other side of the sun from Earth, when its disk appears at its smallest.

What’s happening and when to look

Venus is beautifully placed this week because it reaches greatest eastern elongation, its widest apparent separation from the sun in the evening sky. Look low in the west after sunset — Venus will be the bright white "star" that appears before the fainter stars even have a chance.

On Aug. 14-15, it sits about 46 degrees from the sun and shines at a magnitude of -4.3 to -4.4, bright enough to dominate twilight but not quite at its most impressive stage of the apparition. The real test comes around Sept. 18, when Venus reaches its greatest brilliancy at magnitude -4.6. Sadly, by then it's going to be rather low in the sky from mid-northern latitudes, making observation from the U.K. difficult, but possible from most of the U.S.

According to Sky & Telescope, to catch a faint but well-defined shadow of Venus — a point source of light — you'll need to be somewhere free from artificial lighting and wait until twilight is over. Face Venus and place a white surface (a white card or sheet works well) also facing Venus. You'll also need to position something in front of the card to cast a shadow. Although it is possible to see the faint shadow of Venus, photographing the card is the best way to capture it, using a technique similar to that for any night sky photograph — a high ISO, a wide aperture and a long exposure of up to 30 seconds. It may be wise to test the location, find the best line of sight, and work out where the card needs to go while Venus is still high enough above the western horizon.

If you're not in a good location to catch the shadow of Venus, instead try to see and photograph the light from Venus reflecting on water. Any pond, lake or ocean you can get between you and Venus ought to catch its shine in a long exposure image. That identical technique — high ISO, a wide aperture and a long exposure — will also apply, but this time you can actually aim your camera at Venus!

Stargazer’s Corner: August 14-20, 2026

This is an excellent week for darkness and faint objects. With new moon on Aug. 12, this week is all about a crescent moon. On Aug. 15 you may catch a 12%-lit waxing crescent close to Venus, but more likely you'll see it on Aug, 16, when it will be 19%-lit. The latter occasion is one to aim for — a beautiful sight. On both occasions, look for "earthshine" on the darkened limb of the moon — sunlight reflected by Earth, and something else you can try to capture with a long exposure. The waxing crescent moon will be low in the western evening sky, but early in the week it sets early enough to leave most of the night usable for stargazing and deep-sky astronomy.

The buzz around the Perseid meteor shower, like the solar eclipse, will by now have completely dissipated, but they're still active after their Aug. 12-13 peak, though rates will be lower. With the moon mostly out of the way, it is still worth spending time outside after midnight in the hope of finding "shooting stars." However, the main attraction during dark nights in August is the Milky Way, which streams through the Summer Triangle to Scorpius and Sagittarius. Every time I see the Summer Triangle stars high in the night sky, I tell myself that the Milky Way is right there — and hidden from us by light pollution. It's a reminder to get to a dark-sky site as much as possible when the moon is down (the period between last-quarter moon and new moon is the best week of any month).

Constellation of the week: Scorpius

Scorpius is one of the most distinctive constellations visible from mid-northern latitudes, though it never climbs very high. Its bright red star Antares marks the heart of the scorpion, with a curving tail extending downward toward the horizon. You can see Antares above Venus as it gets dark — a bright, dominating star that's a waymarker of summer in the Northern Hemisphere.

Even in brighter skies, its shape is recognizable, forming a hooked pattern that stands out from the surrounding stars. Because it sits low in the south, it's best observed earlier in the evening before it begins to set. It's one of the few constellations that genuinely resembles its name — and it's where to see the Milky Way meet the horizon.

Science seems like a straightforward endeavour. You come up with a hypothesis, collect data to prove or disprove it, and analyze that data to see if the hypothesis is right. But anyone who actually does science will tell you many times it’s not that straightforward. And one of the most common complexities is in data analysis. A new paper suggests that one such complexity, known as regression to the mean, might be causing us to massively underestimate how severe solar storms can truly be.

The heart of the Milky Way may be more hospitable to water than astronomers thought.

Using the James Webb Space Telescope (JWST), researchers detected water and cosmic dust around an aging star only 0.55 light-years from Sagittarius A* (Sgr A*), the supermassive black hole at the center of our galaxy.

The new study suggests that water and dust can form and survive surprisingly close to a supermassive black hole, where intense radiation and other harsh conditions might otherwise be expected to destroy them. The team used Webb's Mid-Infrared Instrument (MIRI) to study IRS 3, an aging star located in the crowded environment surrounding Sgr A*, which has a mass of about 4 million suns, according to a statement from the European Space Agency (ESA).

"Galactic centres are among the most extreme environments, so understanding whether stars can continue enriching their surroundings there is an important question," Florian Peißker, lead author of the study from the University of Cologne in Germany, said in the statement. "With Webb, we can directly observe how stars behave under these conditions and see that dust production remains remarkably resilient."

IRS 3 — one of the brightest mid-infrared sources in the galactic center — is an asymptotic giant branch star, meaning it has reached a late stage of stellar evolution in which it sheds large amounts of gas and dust through powerful stellar winds. Such dying stars act as cosmic recycling centers, returning material to space that can eventually become incorporated into future generations of stars and planets.

But IRS 3 lives in a particularly unforgiving neighborhood. The center of the Milky Way is densely packed with stars and exposed to intense radiation, raising questions about whether molecules and newly produced dust can persist there.

However, Webb's observations suggest they can. By combining observations of IRS 3's spectrum with simulations of how its light travels through different models of the surrounding material, researchers reconstructed the structure of the star's envelope. They found a layered, shell-like distribution of silicate dust extending roughly 10,000 astronomical units from the star (one astronomical unit, or AU, is the average distance between Earth and the sun). Temperatures within the envelope fall from about 1,700 degrees Fahrenheit (927 degrees Celsius) near the star to around minus 280 F (minus 173 C) in its outer regions. Webb's observations also revealed clear evidence of water within the envelope — the first such detection for IRS 3.

"The detection of water is especially exciting because it shows that molecular material can survive in an environment dominated by intense radiation," Macarena Garcia Marin, co-author of the study and an ESA astronomer, said in the statement.

While the observations don't reveal how much water is present, the detection shows that water can survive in the harsh environment near the galactic center. Water and dust are important ingredients in the chemistry that accompanies star and planet formation, meaning material shed by aging stars such as IRS 3 could eventually contribute to future generations of stars and planets.

Finding water and dust near Sgr A* therefore suggests that aging stars can continue enriching their surroundings even in the harsh conditions near a supermassive black hole. The findings could help astronomers better understand how material is recycled in the centers of galaxies and the role evolved stars play in supplying those regions with fresh dust and molecules.

Their findings were published Aug. 11 in the journal Astronomy & Astrophysics.

On Aug. 14, 1992, a space rock entered the atmosphere over Mbale, Uganda and exploded into hundreds of pieces!

Debris from this meteorite shower was strewn over an area of about 2 by 4 miles (3.2 to 6.4 kilometers), and the biggest piece weighed more than 60 pounds (27 kilograms)! Scientists estimated that the original space rocket weighed more than 2,000 pounds (900 kg). A young boy was hit in the head with a small meteorite fragment, but thankfully no one was seriously injured or killed by any of the falling space rocks.

In October 2012, a fragment of the Mbale meteorite was put up for sale by Heritage Auctions in New York City.

The Mbale meteorite provided scientists with a glimpse of how space rocks of this size can impact communities where they happen to land, and allowed researchers a look at large fragments found by recovery expeditions for radionuclide studies within just 12 days of falling to Earth.

NASA classified Mbale as a type L5/6 ordinary chondrite, and calculated that its breakup in Earth's atmosphere occurred between about 15.5 miles (25 km) and 6 miles (10 km) in altitude. By October 1993, 863 fragments of the meteorite had been recovered, with an overall estimate of 330 pounds (150 kg) of material surviving the atmospheric plunge to reach Earth's surface.

This week's total solar eclipse captured the world's attention, and millions of skywatchers looked up (with the correct protective eyewear, hopefully) to experience the moon blocking out our star's light. And, as you can see in this image, even the International Space Station (ISS) itself got in on the fun.

What is it?

On Aug. 12, 2026, the moon completely blocked out the sun's light for millions of lucky skywatchers witnessing a total solar eclipse.

But the moon isn't the only thing orbiting Earth. Tons of satellites and probes do too, and that includes the ISS. This created a truly remarkable moment for some skywatchers. With the right equipment, it was possible to see the silhouette of the ISS in front of the sun.

This composite image shows eight different frames of the ISS silhouetted on the sun's face as the moon takes a "bite" out of our star to create a partial eclipse.

Solar eclipses like this week's total solar eclipse really bring people together. It creates opportunities for humans to come together and gather for a common goal.

And while the ISS is featured in this image, we may also want to consider the astronauts aboard. In other words, people on Earth weren't the only ones who got to participate in the marvel.

The Expedition 75 astronauts on the ISS (NASA astronauts Jessica Meir, Anil Menon, and Jack Hathaway; ESA (European Space Agency) astronaut Sophie Adenot; and Roscosmos cosmonauts Pyotr Dubrov, Andrey Fedyaev and Anna Kikina) caught the show too as they orbited our planet. There they were, in between Earth and the moon, as our planet's neighbor blocked out our star.

Discover our week through the lens

NASA has formally invited India to participate in its effort to build a permanent base near the moon's south pole, adding a new dimension to the deep-space cooperation between the two countries.

The invitation was extended last week at the Indian space agency ISRO's headquarters in Bengaluru during the ninth meeting of the U.S.-India Civil Space Joint Working Group. The CSJWG was established in 2005 as a mechanism for bilateral space cooperation and for addressing challenges and pursuing mutual spaceflight goals.

"Building on our successful collaboration in science, NASA reaffirmed its interest in @ISRO joining Moon Base. We're going back to the moon to stay — and we're bringing our partners with us," NASA officials said via X on Tuesday (Aug. 11).

Beyond the lunar base invitation, "the two sides also agreed to advance discussions for cooperation on open scientific data sharing under the Accords," reads a Tuesday statement by the U.S. Embassy in India.

"The Accords" are the Artemis Accords, the U.S.-led diplomatic framework outlining principles for safe and responsible exploration of the moon and beyond. India signed on as the 27th signatory in 2023, joining a coalition that has now grown to 70 nations.

Official statements have provided few details on what India's participation in the Moon Base program would entail in practice. The meeting, however, brought together senior space officials from both countries, including V. Narayanan, the chairman of ISRO and secretary of India's Department of Space, and Sergio Gor, the U.S. Ambassador to India, who addressed the opening session, according to the statement.

The meeting was co-chaired by M. Sankaran, director of ISRO's U.R. Rao Satellite Centre, on the Indian side, and two people on the U.S. side — Wesley Brooks, assistant secretary of state for the U.S. Department of State's Oceans and International Environmental and Scientific Affairs, and Kathleen Karika, NASA associate administrator for International and Interagency Relations, the statement reads.

Over the coming decade, via its Artemis program, NASA plans to build out a sprawling, city-like base near the moon's south pole, a region of particular interest thanks to permanently shadowed craters there that are thought to contain substantial deposits of water ice.

Details of the planned architecture shared by NASA in May envision hilltop habitats to take advantage of sunlight and nuclear power systems located farther away to mitigate radiation risks. The space agency also plans to use small, hopping robots starting in 2028 to scout the south polar region ahead of moon base construction.

This effort to gather information and secure access to the surface is the first of three planned phases. Phase 2, from 2029-2032, is intended to establish the base's initial operating capability. Phase 3, from 2032 onward, aims to achieve a semi-permanent crew presence on the lunar surface, NASA said during the May update.

To prioritize infrastructure that supports sustained operations on the moon's surface, increase launch cadence and keep pace with China's lunar ambitions, NASA earlier this year paused development of its long-planned Gateway space station.

For India, the invitation to join NASA's Moon Base program comes as the country pursues its own ambitious lunar exploration and human spaceflight roadmap. Its plans for the 2040s include developing a moon base, establishing a space station in lunar orbit and sending Indian astronauts to the moon, with the broader goal of building long-term human presence beyond Earth.

Betelgeuse, the sky’s most famous red supergiant, is well studied but poorly understood

The moon dust has settled after a 4.5-ton SpaceX rocket body slammed into terrain near Einstein Crater on Aug. 5.

That impact site was imaged by South Korea's moon-orbiting Danuri spacecraft, as well as by NASA's Lunar Reconnaissance Orbiter (LRO). Reportedly, a Chinese commercial space debris monitoring satellite tracked and recorded the 5,400-mph (8,690-kph) moon punch, too.

Wandering through space for over a year, the leftover Falcon 9 upper stage had sent Firefly Aerospace's Blue Ghost-1 lander on its way to the moon back on Jan. 15, 2025. Also sent moonward on that flight was the Hakuto-R Mission 2's Resilience, a robotic lunar lander developed by the Japanese company ispace. While the moon has reclaimed its serenity, the implications of the uncontrolled collision continue to reverberate.

Close encounter

Interestingly, there was also the prospect of a too-close-for-comfort conjunction of the Falcon 9 upper stage and Danuri.

"We noticed roughly late June that there is an incoming Falcon 9 upper stage toward the moon, and also knew that it would be close to Danuri," Eunhyeuk Kim, a senior researcher at the Korea Aerospace Research Institute (KARI), told Space.com.

There was a huge uncertainty in the predicted trajectory of the upper stage, Kim said, while the orbit information of South Korea's Danuri lunar orbiter was quite accurate. "Therefore, we could not neglect the probability of an incoming and close encounter."

However, around mid July, the KARI/Danuri team performed a maneuver of the spacecraft in preparation of a near-total lunar eclipse on Aug. 28, said Kim. That eclipse will see 96% of the moon's visible surface passing through Earth's dark umbral shadow.

Kim said that the orbiter's maneuver brought a slight change in the phase of the spacecraft's orbit, which canceled the probable conjunction between the upper stage and Danuri.

At the time of the Aug. 5 impact, Danuri was flying over the moon's south pole area, far away from the hit zone, said Kim.

Dean Sladen is a quality manager and aerospace engineer in the United Kingdom for Accu Components, a high-precision manufacturing firm.

"As space agencies and private companies build out permanent lunar infrastructure, uncontrolled rocket stages evolve from a minor nuisance into a tangible operational risk," Sladen told Space.com. "A direct hit is the obvious worst-case scenario, but distant impacts also generate ground shocks and high-speed ejecta that can degrade sensitive equipment over time."

Sladen noted that lunar impacts have been a constant throughout history, with meteorites and comets bombarding the surface unhindered by an atmosphere. "Over the past 65 years, artificial objects have added a new dynamic to these events," he added.

Even modest hardware impacts permanently alter the lunar landscape, said Sladen. Given the moon's lack of a substantial atmosphere, there is no air resistance to slow debris down. An impact therefore hurls high-speed ejecta (fine regolith and rock fragments) across vast distances at bullet-like speeds.

"While this isn't a major threat to isolated missions today, as we establish permanent lunar infrastructure, high-velocity ejecta poses a genuine hazard to surface habitats, solar arrays and working astronauts," Sladen said.

To mitigate this issue, Sladen suggested that the industry will likely need designated impact zones or strictly controlled, targeted de-orbit protocols to ensure that spent hardware lands far from active installations.

"That said, human-made debris is only half the equation," Sladen continued. "Natural meteorites remain an ongoing background threat, and, while massive natural strikes are rare, they hit at significantly higher speeds and carry far more energy," Sladen said. "Controlling our own hardware is simply the part of the risk profile we actually have the power to manage."

Plume detections

In the meantime, while the Falcon 9 impact was tough to see from Earth, several observations from our planet reported the detection of sodium and lithium gas above the crash site.

The European Southern Observatory's (ESO) Very Large Telescope (VLT) in Chile, for example, saw the aftermath of the impact. The ESO reported that a chemical fingerprint of the impact was visible for five to 10 minutes, with an enormous plume of lunar material stirred up due to the hard-hitting hardware.

"I'm happy that ESO recorded some evidence of it through VLT, and Danuri has found the exact impact location," said William Jo, a graduate research assistant at the University of Texas, Austin who performed some pre-strike computer simulations.

"What we've learned so far is that the plume was too faint to see against the bright lunar surface, and only a large observatory telescope could pick some parts of it out against the dark sky, which is exactly what happened," Jo told Space.com. "The plume must have shot out high," he said, "and I'd like to know how high, or even whether we can replicate the signals."

Targets of opportunity

"Telescopes make the best spaceships," pointed out Elaina Hyde, director of the Allan I Carswell Observatory at York University in Canada. "We are always on the lookout for 'targets of opportunity' like this event."

Hyde organized a livestream event, training the observatory on the collision locale. They were unable to spot the impact, however.

"The lunar collision was not on our regular research program, but when it happened, we put it as a high-priority item to observe if the weather was clear," Hyde said. "Anything that happens quickly like this is often a target of opportunity, because you do not get a long time to plan the observation."

"However, since it was not visible from our location in Toronto, our 'null' or non detection can actually help to limit the estimates on how big the dust plume was and perhaps some of its properties," said Hyde.

(Image credit: Lowell Observatory)Impact response

Also on the moon impact watch were observers using Lowell Observatory equipment in Arizona.

These researchers managed to measure a response from the rocket stage impact, spotting a sizable sodium and lithium gas plume that lasted between five and 10 minutes after impact, reported Carl Schmidt, an assistant research professor at Boston University's Center for Space Physics.

Observers at the 4.3-meter Lowell Discovery Telescope (LDT) in Happy Jack, Arizona used a long slit spectrograph to detect the plume. Graduate students from Boston University continue to analyze data gleaned from the moon wallop.

Bright lithium plume

"At LDT, we saw a bright lithium plume from the rocket body and fainter sodium [signature], likely from the surface itself," Patrick Lierle of Boston University told Space.com. "The bright lithium plume extends more than halfway up our field of view." The LDT results are also credited to Emma Lovett, a Boston University graduate student.

William Jo said he's looking forward to the release of observational data about the impact before he and colleagues can refine their lunar ejecta simulation model.

"That data, combined with our simulations, could tell us things like the composition of the lunar material, what orientation the impact hit at, and so on," Jo said.

On 12 August 2026, Europe witnessed the first total solar eclipse in over two decades. Millions of people were awed by the Moon completely covering the Sun's bright disc, briefly turning day into night and revealing the Sun's outer atmosphere. Totality could be seen from Greenland, Iceland, Spain and Portugal, while most of the rest of Europe saw a partial eclipse.

Small telescopes have really come on leaps and bounds in recent years. There was a time when refractors with apertures smaller than 4 inches were seldom to be recommended, but manufacturers have been pushing the capabilities of smaller apertures ever further, with optical coatings and high quality, mass-produced optics helping to eke out every little bit of capability from these pocket-sized instruments.

While still aperture-limited — a smaller aperture makes less light received, which makes faint objects harder to see and details harder to resolve — a good small telescope can excel at the things it can do. This include showing fabulous views of the whole moon, revealing the phases of Mercury and Venus, showing surface features on Mars when the Red Planet is at a close opposition, tracking the Galilean moons of Jupiter, splitting double stars, showcasing open star clusters and revealing the very brightest deep-sky objects, including the Orion Nebula and the Andromeda Galaxy.

The Celestron Moon Mission Travel-scope 70 portable telescope is a re-skin of the plain Celestron Travel-scope 70, and is labelled as a lunar telescope. The moon is what it excels at, which is particularly handy in the year that humans went back to the moon for the first time since 1972, drumming up all kinds of excitement about our nearest neighbor.

Its affordable price and simplicity of use further increase its attraction for children. How many young astronomers will find a passion for space after being excited by the Artemis II mission and then seeing the moon for themselves through the eyepiece of this easy-to-use telescope?

• Quick and simple set-up
• Comes with all the accessories to get started
• Lightweight and portable

Inside the box we found the telescope tube, which is just 17 inches (44 centimeters) long, kept within a protective travel bag. Also present were the two eyepieces (10mm and 20mm), a 3x Barlow lens, a moon filter, a star diagonal, a finderscope with crosshairs and a useful moon map poster. There are even free download options for the well-known Starry Night planetarium software and Celestron’s Sky Portal mobile app. All in all, it’s a complete package for anyone wanting to get started in astronomy. The only thing it doesn’t come with is guaranteed clear nights!

Everything is lightweight, so there is no risk of children hurting themselves if they drop anything (though one would advise not dropping the telescope tube!). No tools are required for assembly, which is an additional advantage when aiming a telescope at children. The finderscope is attached by chunky thumb screws, the telescope tube screws onto the pan of the mount, and the tripod legs extend via a series of latches.

• The moon looks superb through both eyepieces
• Ideal for following Jupiter’s moons
• Open star cluster Messier 35 was easily shown

The view of the crescent moon while it was in the constellation of Gemini, the Twins, and near Jupiter, was impressive. First using the 20mm eyepiece at 20x, the whole moon easily fit into the field of view. Though the moon’s phase was two days away from first quarter, through the eyepiece we could easily see the silhouette of the whole moon’s disk thanks to earthshine.

During the time we observed the moon, the day/night terminator cut close to the crater trio of Theophilus, Cyrillus and Catharina around the edge of Mare Nectaris. Other lunar seas including Mare Crisium, Mare Tranquilitatis (landing site of Apollo 11) and Mare Serenitatis were nicely displayed.

Through the 8mm eyepiece at 40x, the moon filled the field of view. The low-angled sun cast dark shadows below the crater walls, which contrasted nicely with the bright surface. Just beyond the terminator, the peaks of crater walls and highlands caught the sun, islands of daylight on the edge of night. All in all, it was a very pleasing view.

A short hop brought us to Jupiter, the moon’s close neighbor for the night. As expected, we found the sub-3-inch aperture unsuitable for revealing any details in Jupiter’s atmosphere — the gas giant just appeared as a bright disk. Its four Galilean moons could be seen to either side, however. We tried with both the 20mm and the 8mm eyepiece: Jupiter’s moons were evident in both and filled the view in the 8mm, appearing as points of light accompanying Jupiter.

Close by in Gemini was Messier 35, an open star cluster that is technically visible with the naked eye, but only from the darkest sites in a moonless sky. Through a 70mm telescope it should be much easier to see, and it was, appearing as a faint smattering of stars against the night sky.

We could not, however, see NGC 2158 — a neighboring open star cluster that is much fainter at magnitude +8.6. This revealed the limitations of a 70mm telescope as opposed to a 100mm (4-inch) or 127mm (5-inch) aperture.

Celestron Moon Mission Travel-scope 70: Functionality

We'd have preferred if the tripod was a little more stable. (Image credit: Gemma Lavender)

• Wobbly tripod
• Accessories are a mixed bag

The actual telescope is as smooth as they come. We found the focuser is good enough for the price point, the two supplied eyepieces aren’t at all bad, and the optics were pretty crystal-clear. For more experienced users with larger telescopes, this 70mm telescope would make a fine finderscope. But what massively lets down the Celestron Moon Mission Travel-scope 70 portable telescope is the tripod that comes with it.

We found the tripod to be incredibly flimsy, and this resulted in vibrations that would shake and blur the view through the eyepiece. Every time we used the pan-handle to turn the telescope and mount head, the tripod would wobble, setting up a feedback of vibrations which we would then have to wait to settle down. The same happened whenever we adjusted focus. While budget telescopes typically do come with poor tripods, we definitely recommend investing in a better tripod as soon as you can.

The 3x Barlow lens also felt like overkill to us. For a 70mm aperture we would not recommend pushing the magnification too high: the telescope simply does not have sufficient aperture to capture enough light for such high magnifications, and the view just becomes a blur. Anything above 100x for a 70mm aperture is too much in our view, yet when used with the 10mm eyepiece (which has a power of 40x) the Barlow lens pushed the magnification up to 120x. We think a 2x Barlow lens would have sufficed.

We were indifferent to the moon filter. When screwed into the eyepiece it just dulled the moon and made it look red and drab, similar to how it might appear during a lunar eclipse. Admittedly it might be more useful when looking at a full moon rather than a crescent, when there are no shadows or contrast on the surface, but we found we preferred not to bother with the filter.

Overall, the telescope’s engineering is decent for the price, but replacing most or all of the accessories would not be unwarranted. But given how much it would cost to do so, if you are intending to spend that money then it would be better just to buy a more expensive, larger-aperture and better quality telescope.

Should you buy the Celestron Moon Mission Travel-scope 70 portable telescope?Buy it if:

✅ You want an affordable telescope for a youngster or beginner that is easy to use and set-up

✅ You are interested in viewing the moon and following its changing phases, and how the illumination alters the view of the lunar surface

Don't buy it if:

❌ You are a deep-sky observer hoping to track down faint fuzzies

❌ You hope to do astrophotography (beyond simple afocal photography at the eyepiece).

If the Celestron Moon Mission Travel-scope 70 portable telescope isn't for you

If you are looking for a telescope for astrophotography that is also relatively simple to use and won’t break the bank, consider ZWO’s SeeStar S30 smart telescope.

If you are looking for something that’s still affordable, but with a little more aperture, try Sky-Watcher’s Explorer 130 EQ2 telescope.

If you want a telescope that has the same 70mm aperture but is a little more high-tech, go for Celestron’s StarSense Explorer LT70AZ refractor, which uses Celestron’s StarSense mobile app technology.

If you want a lot more aperture to track down faint deep-sky objects or to clearly see the belts and rings of Jupiter and Saturn, go for Celestron’s StarSense Explorer 8-inch Dobsonian.

User reviews

There were not many customer reviews of the Celestron Moon Mission Travel-scope 70 portable telescope available at the time of writing, but as it is identical in all but aesthetics and a few accessories to the standard Celestron Travel-scope 70, we can use reviews of the latter as a guide.

The consensus on Amazon was that users were mostly delighted by the telescope, valuing how easy it is to set up and use, as well as its portability and appropriateness for children. However, they shared our concerns about the flimsiness of the tripod.

How we tested the Celestron Moon Mission Travel-scope 70 portable telescope

We took advantage of the clear, mild spring weather that the southwest of England enjoyed in the week beginning April 20, observing around 9.30pm. In particular, we took time to study the moon on the evening of April 22, from a south- and southwest-facing garden.

Astronomy Picture of the Day

Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer.

Total Solar Eclipse from Greenland

Explanation: On August 12, the Moon’s shadow reached out to touch our fair planet. Beginning in the Arctic Ocean, it swept along a narrow track that led the dark lunar umbra across parts of Greenland, Iceland, the Atlantic, Portugal, and northern Spain. And for a moment, denizens of Earth who found themselves with clear skies under the shadow of the Moon could witness a total solar eclipse. After dodging the weather by sea and making a landing along Rype Fjord on the Greenland east coast (at 71.07055N, 27.71252W), this hard-won snapshot was captured at 17:33:26 UTC. That’s near the initial reach of clearing skies along the path of totality, so the image is likely one of the first unobstructed views of the totally eclipsed Sun. Through a break in the clouds, the stunning photo also records one of this eclipse’s transient diamond rings and the magnificent solar corona emerging near the moment totality began.
