For the first time, researchers have studied a series of events beginning 14 million years ago that caused a still-expanding cosmic bubble to envelop Earth’s galactic neighborhood, forming all the nearby stars, a statement explains. Called the Local Bubble, the expanse stretches 1,000-light-years-wide. Within 500-light-years of Earth, all stars and star-forming regions sit on the surface of the Local Bubble, but not inside, giving clues to why Earth sits in a part of the Milky Way Galaxy that is mostly empty, reports Denise Chow for NBC News.
Scientists have suspected the giant bubble’s existence for decades. However, astronomers only recently have observed the net, its shape, and how far it reaches. Astronomers at the Harvard-Smithsonian Center for Astrophysics (CfA) and the Space Telescope Science Institute (STScI) published the study this week in Nature.
The Local Bubble formed from a series of supernovae, or powerful explosions that take place when stars collapse at the end of their life span, reports NBC News. These explosions occurred near the void’s center and blasted gas across space over the last 14 million years. Read More:
