NASA Science Soars During August Total Solar Eclipse

Hubble shows star formation in Andromeda galaxy is winding down A new study using data from NASA’s Hubble Space Telescope finds that star formation in the nearby Andromeda galaxy has undergone a 500-million-year decline, with an even steeper drop in the last 40 million years. Andromeda, a spiral galaxy comparable in size to our Milky Way, is close enough to be seen with the unaided eye from areas with dark skies.

Located about 2.5 million light-years from Earth—practically our cosmic backyard—Andromeda offers an opportunity for astronomers to examine its stellar populations in detail, leading to a better understanding of the past of galaxies like our own.
