Even a century after Edward Hubble confirmed its existence, astronomers learn new details about the Andromeda galaxy that help us better understand our cosmic neighborhood and the wider universe. Earlier this week, NASA released its latest detailed images of the Milky Way’s spiral sibling, as well an ethereal sonification of its energy wavelengths. Also known as Andromeda, the Milky Way’s most immediate neighbor is about 2.5 million light-years away, and provides an excellent option for studying how spiral galaxies form and evolve over time.

There’s still an untold wealth of information to learn from the Milky Way’s neighbor, possibly even the means to finally understand the dark matter first detected by Rubin.
