The Sombrero Galaxy
Galaxies are islands of stars in space. When a star is born, it creates stellar winds, ultraviolet radiation, and sends shock waves into space, giving shape to the galaxy around it. In the Sombrero Galaxy - located 28 million light years away in the constellation Virgo - star formation creates a dramatic red ring of warm dust around a central blue bulge.
