CosmoView Episode 27: An Astronomer’s Menagerie

An image of the dwarf galaxy Sextans B, taken with the Nicholas U. Mayall 4-meter Telescope at Kitt Peak National Observatory, a Program of NSF’s NOIRLab, contains a menagerie of astronomical objects, from bright stars in the foreground to distant galaxies hiding in the background. The galaxy itself contains both the cradles and the graves of stars, hosting star-forming regions as well as stellar death shrouds.
