Blue and white stars shine brilliantly against a crimson background of glowing gas in this July 3, 2026, image of stellar nursery LH 95 from NASA’s Hubble Space Telescope. LH 95 is a region in the Large Magellanic Cloud, a dwarf galaxy that orbits the Milky Way. Low-mass infant stars live alongside massive blue giant stars in […]

This image from NASA’s Hubble Space Telescope showcases Messier 3 (M3), one of the Milky Way galaxy’s most massive globular clusters, or spherical collections of gravitationally bound stars. Globular clusters are made up of ancient stars that formed at roughly the same time from the same cloud of gas, giving those stars similar ages. Around 150 known globular clusters are […]

Red, white, and blue stars glitter like a sparkler being waved on a dark night in this new image from NASA’s Hubble Space Telescope.

NASA’s James Webb Space Telescope recently observed edge-on starburst galaxy Messier 82 (M82), nicknamed the Cigar Galaxy. Webb’s new view of M82, added to archival data from NASA’s Hubble Space Telescope, gives us a more complete picture of this starburst galaxy. Because Webb can see infrared light, it is able to peer through clouds of […]

Astronomers using NASA’s Hubble Space Telescope have found something they never expected — ultraviolet light from a galaxy that existed just 1.4 billion years after the big bang.

This NASA Hubble Space Telescope image features a galaxy cluster, called CL0016+1609 or MACS J0018.5+1626, that is very bright at X-ray wavelengths and is one of the most extensively studied clusters at X-ray and radio wavelengths. The X-ray observations of this cluster revealed that it is two clusters merging along our line of sight. Researchers […]

Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image released on June 12, 2026, features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how the structure of the universe evolved, and are the ultimate telescopic lenses, placing gravitationally lensed galaxies from the […]

Researchers using two of humanity’s most powerful observatories — NASA’s James Webb and Hubble Space Telescopes — have definitively shown that Terzan 5 is not a globular star cluster as it was once classified, offering new insight into how galaxies like our own form and evolve over time. A globular star cluster typically has only […]

Researchers have confirmed a new class of objects within our Milky Way galaxy: survivors called 'bulge fossil fragments.' Terzan 5 is the prototype of these remnants of our galaxy's early formation. Using the NASA/ESA/CSA James Webb Space Telescope and the NASA/ESA Hubble Space Telescopes researchers have shown that Terzan 5 is not a globular star cluster as it was once classified. Instead, it is something much odder and rarer.

This March 20, 2026, image of Messier 64, or the Black Eye Galaxy, is a composite view from NASA’s Hubble Space Telescope and James Webb Space Telescope. It shows Messier 64 captured at near- and mid-infrared wavelengths by Webb, while Hubble’s image shows the galaxy in ultraviolet, visible, and near-infrared light. Messier 64 is characterized […]
