Today’s Image of the Day from NASA features a rapidly aging star that has been nicknamed “Nasty 1” as a funny twist on its technical name, NaSt1.
Nasty 1 was identified as a Wolf-Rayet star, which is a rapidly evolving star that is larger than the sun. However, Nasty 1 does not look like a typical Wolf-Rayet star and behaves very differently from any other star in our Milky Way galaxy.
With the help of the Hubble Space Telescope, scientists have uncovered surprising new clues about the star.
Nasty 1 is believed to have an unseen companion star, and gravitational interactions between them may have formed the massive gas disk that surrounds the system, which is nearly two trillion miles wide.
