This image of interstellar comet 3I/ATLAS was taken on 18 February 2026 with the FORS2 instrument on ESO’s Very Large Telescope (VLT). It is a stack of several images spanning 13 minutes. As the comet moves on the sky, the stars appear as trails in the background.
This image shows part of the spectrum of interstellar comet 3I/ATLAS, captured between 6 and 26 December 2025 with the UVES instrument on ESO’s Very Large Telescope (VLT). Using UVES, astronomers studied the spectral signatures of cyanide, a molecule comprised of a carbon atom and a nitrogen...
The subject of today’s ESA/Hubble Picture of the Month is an ancient inhabitant of our galaxy. This sparkling scene is of a globular cluster: a collection of tens of thousands to millions of stars, all tightly bound together under the influence of gravity. Astronomers know of more than 150...
Messier 104, nicknamed the Sombrero galaxy, is a popular target for amateur observing and astronomical research. Its recognizable extended halo and dust-filled disk are captured in this image from the Department of Energy-fabricated Dark Energy Camera (DECam) mounted on the U.S. National...
Celebrating the birth of new stars... and the VST!
Imagine for a moment you are lying back, gazing up at the red-orange celestial clouds in today’s Picture of the Week. What shapes do you see? A chicken pecking seeds on the ground, the head of a dragon, or something else entirely? These pareidolia-inducing clouds are a pair of nebulae —...

The 8.1-meter Gemini North telescope, located on the summit of Maunakea in Hawai‘i, has captured NGC 1514, nicknamed the Crystal Ball Nebula, in awe-inspiring detail. This nebula, with its mesmerizing glow of gas, harbors hints of a past stellar death, and its asymmetrical shell is now being...
This image shows the field around the gravitationally lensed galaxy nicknamed "Shadow Blaster." This galaxy lies 11 billion light-years away and sits just behind the bright red galaxy at the center of this image. The red foreground galaxy acts like a cosmic magnifying glass, enlarging and...
This image shows the gravitationally lensed galaxy nicknamed "Shadow Blaster," which astronomers have identified as the likely source of the high-energy neutrino event IC 210922A, detected by the IceCube Neutrino Observatory in 2021. Gravitational lensing occurs when a very massive foreground...
