Earth from Space: Buenos Aires
This radar image from the Copernicus Sentinel-1 mission captures Buenos Aires, the capital of Argentina, the surrounding countryside and the Rio de la Plata estuary.
Zoom in to explore this image at its full resolution.
This is a composite of three Sentinel-1 acquisitions taken in January, March and May this year, with each image assigned to a different colour channel (blue in January, green in March and red in May). As the environmental changes on the ground created a significant ‘backscatter’ reflection of the radar signal, they show up as bright shades that correspond to changes across the seasons.
On the right-hand side of the image, the metropolitan area of Buenos Aires is visible in light grey. The area has a population of more than 16 million people and lies at 25 m above sea level. The urban areas were largely unchanged between January and May, hence the lack of colour in this part of the image. Other towns, such as Luján and Junin, are also visible as smaller patches of grey west of the capital.
The blue areas correspond to surface changes such as choppy water, captured in January, which is mid-summer in Argentina. The rivers, deltas and open water are mainly coloured in either dark blue, purple or black. Winds and rough sea conditions during both January and May mean that the Rio de la Plata estuary, east of Buenos Aires, appears purple (a mix of blue in January and red in May). The Paraná river meanders through wetlands on the left of the image before flowing into the Rio de la Plata. The Uruguay river is also seen flowing from the north into the estuary.
To the west of Buenos Aires, agricultural fields and the Argentinean Pampas dominate the landscape. The green tint is due to significant ‘backscatter’ reflection of the radar signal in this area during the capture in March. Since this period is late summer in Argentina, it likely denotes growth of major crops such as soy and corn.
At the top of the image, a large area north of the Paraná river, in Entre Ríos province, appears in vivid red – the channel assigned to ground change in May, which is late Autumn in Argentina. It is likely that this is due to natural vegetation growth caused by seasonal rains during that period. This is when the areas of exposed grassland come back to life following the long, dry summers.
Conversations in the sky: Galileo’s intersatellite links tested
The second generation of Galileo, Europe’s satellite navigation constellation, is being built. These satellites will feature reconfigurable payloads, provide more robust and reliable positioning, navigation and timing, enable new services and add new capabilities to the constellation.
One of these capabilities, intersatellite links, will allow the satellites to communicate with one another in orbit. After going through extensive testing, the intersatellite link antennas are ready to be integrated into the satellites.

The Shape of a Black Hole
Black holes are already strange enough, regions of space where gravity is so extreme that not even light can escape. But physicists have long known there's another layer of weirdness, that black holes also behave like thermodynamic objects, with temperature, entropy, and phase transitions just like a gas or a liquid. Now, a new approach borrowed from pure mathematics is revealing hidden patterns in that behaviour and hinting at something fundamental about the nature of black holes themselves.
Written in Rock
A small rock found in the African desert has just handed scientists an extraordinary window into one of the most violent and consequential periods in the history of the Solar System. Inside this lunar meteorite, a chunk of the Moon knocked to Earth by an ancient collision, researchers have found evidence of a massive impact event 3.5 billion years ago, one that matches the timing of known impacts on Earth and in the asteroid belt. Three worlds but one shared bombardment and a story that may have everything to do with the origins of life.
Titan's Hidden Blanket
Saturn's moon Titan has long fascinated scientists, it’s a world with rivers, lakes, and a thick atmosphere, all made not of water but of methane. Now, a new study suggests Titan is stranger than first imagined since beneath its surface lies a 9 km thick crust of methane laced ice that acts like a giant thermal blanket, warming the interior in ways nobody expected.

NASA’s Chandra Discovers Possible Supernova Remnant in Galactic Center
Using data from NASA’s Chandra X-ray Observatory, astronomers may have found a supernova remnant in an intriguing neighborhood in the middle of our galaxy. A paper describing these new findings published in The Astrophysical Journal.
Supernova remnants are the expanding remains of exploded stars and provide elements – like iron, oxygen, and silicon – that are critical for the formation of planets and for life as we know it to form and flourish.
This new supernova remnant, if confirmed, would be one of the closest ever discovered to the supermassive black hole at the central region of the Milky Way galaxy, an exotic region crammed with massive stars, long threads of magnetic fields and dense clouds of gas orbiting rapidly around the Galactic Center.
Astronomers may have uncovered a new supernova remnant in a star-forming region near the center of the Milky Way galaxy using data from Chandra and XMM-Newton. If confirmed, this would be one of the closest supernova remnants to the supermassive black hole in the Galactic Center. This image shows the region where the evidence was found, which contains X-rays from Chandra and XMM-Newton, radio data from the MeerKAT telescope in South Africa, and an optical image from the Pan-STARRS telescopes in Hawaii. X-ray: NASA/CXC/UCLA/Z. Zhu et al.; ESA/XMM-Newton; Optical: PanSTARRS; Radio: MeerKAT; Infrared (JWST): NASA/ESA/CSA/STScI; Image Processing: NASA/CXC/SAO/L. Frattare and P. Edmonds
A new composite image of this region contains X-rays from Chandra and ESA’s (European Space Agency’s) XMM-Newton mission (shown in blue) as well as radio data from the MeerKAT telescope (shown in red) in South Africa. These have been combined with an optical image from the Pan-STARRS telescopes in Hawaii (red, green, and blue). The plane of the galaxy runs horizontally from left to right in the image, and the central black hole is off to the left of the image.
The evidence for the new supernova remnant, located about 26,000 light-years from Earth, comes from X-ray data from Chandra and XMM-Newton. The X-ray data reveals a “blob” of X-ray emission that may come from the remains of a massive star that self-destructed as a supernova, buried within the larger cloud of expanding gas.
The location of this suspected supernova remnant in the image is labeled with a circle.
It is in a bubble of gas that has had electrons stripped away from hydrogen – called an “H II region” – surrounding a massive, young star. This bubble is a bright source of radio emission called Sagittarius C.
If this is indeed a supernova remnant, then it is expanding at about two million miles per hour and is at least about 1,700 years old. Previously, observations with NASA’s now-retired SOFIA (Stratospheric Observatory for Infrared Astronomy) mission had shown evidence for an expanding shell of gas surrounding Sagittarius C. This gave astronomers a hint that a stellar explosion had occurred in the same spot.
The long filaments seen in the radio image are caused by energetic particles travelling along magnetic fields that are mostly directed perpendicular to the plane of the galaxy.
The nuclear fusion engines of stars create elements from hydrogen and helium that were abundant at the beginning of the universe. When stars explode at the end of their lives as supernovae, they send these newly synthesized elements into interstellar space and provide material for the next generation of stars and planets.
The team of astronomers searched the X-ray data for signs of increased amounts of key elements in the remnant, which would have been caused by the stellar explosion blasting them into space. While they did not see an enhancement, this could imply that the stellar debris has already mixed with the surrounding gas.
An alternative explanation for the X-ray blob is that the hot gas comes from a collection of massive stars in the region. The authors of the recent study don’t think this explanation is likely, because the X-ray emission from the blob is more than ten times brighter than the X-ray emission of large, known stellar clusters with bright, massive stars.
An additional image shows data from NASA’s James Webb Space Telescope added to the X-ray and radio data. The light blue color represents infrared light from gas in the H II region, and the darker blue depicts X-rays from the supernova remnant candidate, on the right side of the image. X-rays near the center of the image are associated with the H II region, possibly caused by material blown away by massive stars that has heated gas to millions of degrees, producing X-rays.

Visual DescriptionThis release features a composite image of colorful, overlapping clouds, which suggests to astronomers that a supernova remnant may be buried in gas near the center of our Milky Way galaxy.
Set against a backdrop packed with distant stars and other specks of light are two distinct, overlapping clouds. The larger, visually dominant cloud, is red and multifaceted. It has an irregular shape, and features patches of different textures, including pockets that resemble wispy smoke, tangles of faint red veins, and clear streaking lines. This large cloud of expanding gas represents radio data from the MeerKAT telescope in South Africa.
Overlapping with that red cloud is a cloudy blue blob representing X-ray data from NASA’s Chandra X-ray Observatory and ESA’s XMM-Newton. Astronomers suggest that this blue blob of X-ray emissions is the remains of a massive star destroyed by a supernova.
