This Hubble Space Telescope picture shows a galaxy named SBS 1415+437 or SDSS CGB 12067.1, located about 45 million light-years from Earth. SBS 1415+437 is a Wolf-Rayet galaxy, a type of starbursting galaxy with an unusually high number of extremely hot and massive stars known as Wolf-Rayet stars. These stars can be around 20 times as massive as the Sun, but blast substantial winds of particles out into space, causing their mass to dwindle at a rapid rate. These massive stars are also incredibly hot, with surface temperatures some 10 to 40 times that of the Sun, and very luminous, glowing at tens of thousands to several million times the brightness of the Sun. Many of the brightest and most massive stars in the Milky Way are Wolf-Rayet stars.
