IC 10


This is an irregular galaxy named IC 10, a member of the Local Group — the nearby group of over 50 galaxies that includes the Milky Way. IC 10 is the closest-known starburst galaxy to us. It is the site of rapid star formation fueled by ample supplies of cool hydrogen gas. This gas condenses into vast molecular clouds which further contract into dense knots where pressures and temperatures reach a point sufficient to ignite nuclear fusion, and new stars are born.
