Galaxies - NASA Science
Galaxies consist of stars, planets, and vast clouds of gas and dust, all bound together by gravity. The largest contain trillions of stars and can be more than a million light-years across. The smallest can contain a few thousand stars and span just a few hundred light-years.

Hubble's collection of images of galaxies reshaped by cosmic collisions and interactions. Witness an Einstein-predicted phenomenon that magnifies light from far-distant galaxies through the gaze of the Hubble Space Telescope.
Found: First Actively Forming Galaxy as Lightweight as ... - Science@NASA
Dec 11, 2024 · Other galaxies Webb has detected at this time […] For the first time, NASA’s James Webb Space Telescope has detected and “weighed” a galaxy that not only existed around 600 million years after the big bang, but is also similar to what our Milky Way galaxy’s mass might have been at the same stage of development. Other galaxies Webb has ...
New 3D Visualization Highlights 5,000 Galaxies Revealed by Webb - NASA
Jul 10, 2023 · This video, a scientific visualization of the galaxies captured as a part of the CEERS (Cosmic Evolution Early Release Science) Survey, showcases a large undertaking by NASA’s James Webb Space Telescope. It flies by thousands of galaxies, starting with those nearby and ending with less-developed galaxies in the very distant universe ...
NASA’s Webb Telescope Reveals Links Between Galaxies Near …
Jan 9, 2023 · A new analysis of distant galaxies imaged by NASA’s James Webb Space Telescope shows that they are extremely young and share some remarkable similarities to “green peas,” a rare class of small galaxies in our cosmic backyard. “With detailed chemical fingerprints of these early galaxies, we see that they include what …
NASA’s Webb Finds Planet-Forming Disks Lived Longer in Early …
Dec 16, 2024 · NASA’s James Webb Space Telescope just solved a conundrum by proving a controversial finding made with the agency’s Hubble Space Telescope more than 20 years ago. In 2003, Hubble provided evidence of a massive planet around a very old star, almost as old as the universe. Such stars possess only small amounts of heavier elements […]
NASA’s James Webb Space Telescope Finds Most Distant Known Galaxy
May 30, 2024 · One such galaxy, JADES-GS-z14-0 (shown in the pullout), was determined to be at a redshift of 14.32 (+0.08/-0.20), making it the current record-holder for the most distant known galaxy. This corresponds to a time less than 300 million years after the big bang.
Hubble Spies a Cosmic Eye - NASA Science
6 days ago · This NASA/ESA Hubble Space Telescope image features the spiral galaxy NGC 2566, which sits 76 million light-years away in the constellation Puppis. A prominent bar of stars stretches across the center of this galaxy, and spiral arms emerge from each end of the bar. Because NGC 2566 appears tilted from our perspective, its disk takes on an almond shape, giving the galaxy the appearance of a ...
