Messier 77


Messier 77 (aka, M77 or NGC 1068) is a barred spiral galaxy about 47 million light-years away in the constellation Cetus. This Hubble visible light image doesn’t reveal M77’s central bar. However, infrared images of the inner part of the galaxy reveal a prominent bar feature, so it is considered a barred spiral galaxy.

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.
