NASA’s James Webb Space Telescope has captured the infrared light of numerous features that previously were impossible to see beyond the thick dust of the FS Tau star system. In addition to myriad background galaxies that burst into view like fireworks for the United States’ 250th anniversary celebrations, this image flickers with a number of protostars, or baby stars that are formed from dense pockets of gas and dust. These hot, clumpy, and low-mass objects eventually will become full-fledged stars capable of burning hydrogen in their cores, like our Sun. The protostars of FS Tau are about 1 to 3 million years old, which is relatively young in cosmic scales. Our Sun, by contrast, is 4.6 billion years old.
Low-mass stars emit less radiation and have less energetic stellar winds than those with larger masses, which means they disrupt their environment at a much lower level. This makes the FS Tau region incredibly useful for studying low-mass star evolution without the same level of environmental interference seen near higher-mass stars. A pair of protostars that creates the largest diffraction pattern seen slightly to the left of center in the image, called FS Tau A, is about half the mass of our Sun.
Image: FS Tau (Webb Image) In infrared light, NASA’s James Webb Space Telescope reveals bright protostars in star system FS Tau and a tapestry of background galaxies. FS Tau B, the orange protostar slightly right of center, is thought to be responsible for the orange outflows amid the dusty region. Image: NASA, ESA, CSA, STScI; Image Processing: Alyssa Pagan (STScI)
Even though these objects are young and low-mass, they still can impact their surroundings, partially due to the outflows they emit. These outflows, seen as orange and red wisps and wide sheets, are theorized to come from FS Tau B, the protostar slightly to the right of center that has an orange diffraction pattern. As FS Tau B feeds on the surrounding dust and gas to grow, it ejects some of that matter outward. The wider outflows are thought to come from the interaction between the protostar’s magnetic field and superheated matter closest to the protostar within its accretion disk. The disk is seen as a dark band that cuts across at a 30-degree angle.
The gaps between the outflows, newly discovered in this Webb observation, add to growing evidence that protostars accrete matter in discrete episodes. In the periods where protostars gather material and increase in mass, they also eject superheated matter in different directions. In between these episodes, they are relatively quiet.
Image: FS Tau Side-by-Side (Webb and Hubble Image) A comparison between the observations of FS Tau by NASA’s Hubble and James Webb space telescopes. Hubble’s visible-light view shows the star-forming region mostly obscured by thick dust. Webb sees through the dust, revealing how the protostars are shaping their surroundings. Image: NASA, ESA, CSA, STScI; Image Processing: Alyssa Pagan (STScI)
As protostars eject these outflows, they shape their surroundings. This is best shown by the prominent light-blue ridges of dust and gas near FS Tau B. These thicker regions were likely created as outflows struck and compressed matter together. The brightness of these light-blue ridges shows that the nearby protostar’s light is reflected. Moreover, Webb’s sensitivity reveals the varying textures of dust and gas across the entire region.
The range of colors seen in this observation also provides a wealth of information, specifically about where dust is and how much of it obscures the region. Light with bluer wavelengths is absorbed and scattered by dust, while redder-wavelength light is able to slip through. Therefore, background galaxies behind thicker foreground dust appear redder. Alternatively, yellow galaxies have much less dust obscuring them. The few white stars visible in this image are likely in the foreground.
The James Webb Space Telescope is the world’s premier space science observatory. Webb is solving mysteries in our solar system, looking beyond to distant worlds around other stars, and probing the mysterious structures and origins of our universe and our place in it. Webb is an international program led by NASA with its partners, ESA (European Space Agency) and CSA (Canadian Space Agency).

What’s Up: July 2026 Skywatching Tips from NASA
A predawn Moon-and-planets meetup, a returning comet, a great chance to see the Milky Way, and Saturn’s rings at a new angle.
Skywatching Highlights- July 7: Last Quarter Moon
- July 11 + 12: Dawn alignment of the Moon, Mars, Saturn, and Uranus
- July 14: New Moon; best dark-sky window for Comet 10P/Tempel 2 and the Milky Way
- Later in July: Saturn’s unusually thin rings are a rewarding telescope target
- July 21: First Quarter Moon
- July 29: Full Moon
An early morning hangout with the Moon and planets, a comet swings by, prime time for the Milky Way, and Saturn’s rings shine at a new angle. That’s What’s Up for July.
Before sunrise on July 11 and 12, look toward the eastern sky for a lineup of the Moon and planets. On these mornings, the waning crescent Moon helps point the way to Mars, with Saturn shining nearby in the morning sky.
Uranus is in the same general part of the sky, too, but it is much fainter, so you will need binoculars or a telescope to see it.
Mars will look like a small reddish point of light, Saturn is brighter and easier to spot, and the Moon makes the whole scene easy to locate.
Before sunrise on July 11 and 12, the Moon, Mars, Saturn, and Uranus will parade in the eastern sky. NASA/JPL-Caltech
Around the New Moon on July 14, Comet 10P/Tempel 2 swings by.
This is a short-period comet, meaning it returns to the inner solar system on a regular orbit. In this case, it comes back about every 5½ years. It is not a dramatic comet that you see just by looking up at the sky, though.
Through binoculars or a telescope, find the constellation Capricornus and look for a small fuzzy glow nearby, possibly with a brighter central knot and a short, broad, fan-shaped tail.
For the best chance to view the comet, head somewhere dark, away from city lights. Start looking once the sky is fully dark, ideally about 45 to 60 minutes after sunset.
NASA/JPL-Caltech
Those same dark nights around the July 14 New Moon are also the best time this month to look for the Milky Way.
From a dark location, away from city lights, the Milky Way appears as a pale, cloudy band across the summer sky. The bright, cloudy region of the Milky Way marks the direction of the galactic center. It looks so dense because we’re looking toward one of the most crowded parts of our galaxy, where countless stars glow behind dark clouds of cosmic dust.
Late in the evening, look low in the southern sky for a group of stars shaped like a big hook or scorpion tail. That’s Scorpius. The bright, cloudy part of the Milky Way is nearby, close to another group of stars called Sagittarius.
For the best chance to see the Milky Way, go somewhere dark, give your eyes time to adjust, and try not to look at your phone.
NASA/JPL-Caltech
Later in July, Saturn is a rewarding target for telescope users.
Saturn’s rings are still tilted at a very shallow angle from our point of view, making them look unusually thin. The rings aren’t disappearing, but how they appear from Earth is changing. It’s a great reminder that our view of the solar system is always in motion.
Saturn is famous for the intriguing rings that encircle it. As Saturn orbits the Sun, though, our view of its rings changes. Roughly every 15 years (halfway through Saturn’s almost-30-year orbit), Saturn’s rings appear edge-on, sometimes seeming to disappear altogether. On Feb. 24, 2009, when Saturn’s rings were nearly edge-on, Hubble tracked four of Saturn’s moons as they passed across the face of the giant ringed planet.
