 Good morning, May Martinez. For a few days this summer, the night sky will get a new star, or rather an explosion that looks like a star for the first time in nearly 80 years. It's actually a nova eruption 3,000 light years away in a constellation called Corona Borealis. There, one type of star, a white dwarf, orbits around another type, a red giant, and steals its matter until, boom, the pressure on the star triggers a blast that can be seen all the way here on Earth. It's Morning Edition.
