In the early universe, the first galaxies began to take shape roughly a million years after the Big Bang. Within these young systems, stars formed from vast reservoirs of cold gas, gradually building the structures we see ...
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 ...
Looking somewhat like a swarm of bees returning to their hive, this NASA Hubble Space Telescope image features the galaxy cluster MACS0329-0211. Galaxy clusters like MACS0329-0211 are important signposts in the story of how ...
After only four short years, NASA's James Webb Space Telescope (JWST) and observational cosmologists like Richard Ellis at University College London (UCL) have pushed the cosmic lookback time to an era when the universe's ...
The complex puzzle known as little red dots has become more complete since their initial discovery by NASA's James Webb Space Telescope in 2022. Now a particular little red dot's spectrum is helping connect many of the pieces.
Unfortunately, there's more bad news to report on the clear skies front. A new paper, available on the arXiv preprint server from researchers at NASA's Ames Research Center, reports that 73.3% of images the agency's new SPHEREx ...
Scientists from the Space Telescope Science Institute (STScI) in Baltimore, Maryland, sought to study one stellar subject and ended up finding something even more exciting. The team's results published today in Astronomy ...
The focus of this NASA/ESA Hubble Space Telescope image is an active spiral galaxy on a journey lasting hundreds of millions of years. The galaxy Messier 88 (M88), also known as NGC 4501, is located about 63 million light-years ...
This NASA Hubble Space Telescope image features the dwarf irregular galaxy ESO 490-017, roughly 12,000 light-years in diameter and some 23 million light-years away in the constellation Canis Major. The galaxy's low surface ...
Look closely at this image from NASA's Hubble Space Telescope and you'll see galaxies of various shapes and sizes clustered together toward the center-left of the image. A few foreground stars shine brightly and are easily ...
