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...
Found: First Actively Forming Galaxy as Lightweight as ... - Science@NASA
2024年12月11日 · 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.
New 3D Visualization Highlights 5,000 Galaxies Revealed by Webb - NASA
2023年7月10日 · While this vast region contains about 100,000 galaxies, the visualization focuses on approximately 5,000 – with the nearest and more complex galaxies, shown in the beginning, located within a few billion light-years of Earth.
Galaxy Types - Science@NASA
Types of Galaxies Scientists sometimes categorize galaxies based on their shapes and physical features. Other classifications organize galaxies by the activity in their central regions – powered by a supersized black hole – and the angle at which we view them.
Hubble Spies a Cosmic Eye - NASA
2024年12月27日 · 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 ...
Hubble's Galaxies - NASA Science
Galaxies are the visible foundation of the universe; each one a collection of stars, planets, gas, dust, and dark matter held together by gravity. Hubble’s observations give us insight into how galaxies form, grow, and evolve through time. Credit: NASA's Goddard Space Flight Center; Lead Producer: Miranda Chabot; Lead Writer: Andrea Gianopoulos
