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.

NASA’s James Webb Space Telescope has peered into the chaos of the Cartwheel Galaxy, revealing new details about star formation... This landscape of “mountains” and “valleys” speckled with glittering stars is actually the edge of a nearby, young, star-forming region...
What Is a Galaxy? | NASA Space Place – NASA Science for Kids
Dec 5, 2024 · A galaxy is a huge collection of gas, dust, and billions of stars and their solar systems, all held together by gravity. We live on a planet called Earth that is part of our solar system. But where is our solar system?
Hubble Spies a Cosmic Eye - NASA Science
5 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 ...
Found: First Actively Forming Galaxy as Lightweight as ... - Science@NASA
Dec 11, 2024 · For the first time, astronomers using NASA’s James Webb Space Telescope have identified a galaxy, nicknamed the Firefly Sparkle, that not only is in the process of assembling and forming stars around 600 million years after the big bang, but also weighs about the same as our Milky Way galaxy if we could “wind back the clock” to weigh it as it developed.
NASA’s Webb Telescope Reveals Links Between Galaxies Near and …
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 …
