Tiny Galaxy, Big Discoveries: NGC 300 and the Secrets of
1 day ago · Astronomers have unveiled surprising new details about a small galaxy, NGC 300, challenging existing theories on galaxy formation. By observing ancient, metal-poor stars and a vast stellar stream extending over 100,000 light-years, the study demonstrates that even dwarf galaxies engage in the accretion of mass from their surroundings, similar ...
Dwarf galaxy - Wikipedia
A dwarf galaxy is a small galaxy composed of about 1000 up to several billion stars, as compared to the Milky Way's 200–400 billion stars. [1] The Large Magellanic Cloud, which closely orbits the Milky Way and contains over 30 billion stars, [2] is sometimes classified as a dwarf galaxy; others consider it a full-fledged galaxy. Dwarf ...
This Tiny Galaxy Is Answering Some Big Questions | STScI
6 days ago · An STScI-led team of astronomers has used the James Webb Space Telescope to study Leo P, a dwarf galaxy located about 5.3 million light years from Earth that was discovered in 2013. Leo P is relatively isolated from other, larger galaxies like the Milky Way and Andromeda, which means it has been unaffected by their influence.
