On October 18, the 4MOST instrument used its 2400 fibres for the first time to analyse the light from different cosmic objects. The spectrograph, which is installed on ESO’s VISTA telescope, observed a large patch of sky containing two prominent objects: the Sculptor Galaxy and the globular...
Webb’s MIRI (Mid-Infrared Instrument) shows the Sagittarius B2 (Sgr B2) region in mid-infrared light, with warm dust glowing brightly. To the right is one clump of clouds that captured astronomers’ attention. It is redder than the rest of the clouds in the image and corresponds to an area that...
Stars, gas and cosmic dust in the Sagittarius B2 molecular cloud glow in near-infrared light, captured by Webb’s NIRCam (Near-Infrared Camera). In this light, astronomers see more of the region’s diverse, colorful stars, but less of its gas and dust structure. Webb’s instruments each provide...
Webb captured this sparkling scene of star birth in Pismis 24, a young star cluster about 5,500 light-years from Earth in the constellation Scorpius. This region is one of the best places to explore the properties of hot young stars and how they evolve.
NASA's James Webb Space Telescope recently imaged an extremely large and symmetric protostellar jet at the outskirts of our Milky Way galaxy in the forming cluster Sh2-284. From tip to tip, this protostellar jet is 8 light-years across, about double the distance from our Sun to its closest...
The mid-infrared view of planetary nebula NGC 6072 from NASA’s James Webb Space Telescope shows expanding circular shells around the outflows from the dying central star, which astronomers suspect is that pinkish white dot at the center of the image. The longer wavelengths captured by Webb’s...
NASA’s James Webb Space Telescope’s view of planetary nebula NGC 6072 in the near-infrared shows a complex scene of multiple outflows expanding out at different angles from a dying star at the center of the scene.
There is one stretching from roughly 11 to 5 o’clock, another from 1 to 7...
This is a Hubble Space Telescope image of the interstellar comet 3I/ATLAS. Hubble photographed the comet on July 21, 2025, when the comet was 277 million miles from Earth. Hubble shows that the comet has a teardrop-shaped cocoon of dust coming off its solid, icy nucleus. Because Hubble was...
A Hubble Space Telescope image of a pair of galaxies: NGC 6099 (lower left) and NGC 6098 (upper right). The purple blob depicts X-ray emission from a compact star cluster. The X-rays are produced by an intermediate-mass black hole tearing apart a star.
Today’s ESA/Hubble Picture of the Week features a galaxy that Hubble has captured multiple times over more than 20 years. The galaxy is called NGC 3370, and it is a spiral galaxy located nearly 90 million light-years away in the constellation Leo (The Lion). What is it about this galaxy that...

The celestial object that is displayed in this NASA/ESA Hubble Space Telescope Picture of the Week is NGC 7496, a galaxy located over 24 million light-years away in the constellation Grus (The Crane). NGC 7496 is a dusty spiral galaxy with a bar of stars stretching across its centre. Adding to...
