Exploring the Cosmic Jewels of Irregular Dwarf Galaxy Sextans A | Mayall Telescope

CosmoView Episode 29: The dwarf galaxy Sextans A is a cosmic jewelry box filled with bright young stars. Located around 4.4 million light-years from Earth, it has been contorted by several supernova explosions that give it a peculiar square shape. The galaxy overflows with young, blue stars and red-hued star-forming regions. This glittering image was taken at the 4-meter Nicholas U. Mayall Telescope at Kitt Peak National Observatory in Arizona.
