Nationalgeographic.co.id—Astronomers have discovered a ‘giant cavity’ in space while studying a 3-D map of a nearby star-forming gas and dust cloud. This spherical cavity is 500 light-years wide, spans about 150 parsecs, and lies between clusters of star-forming gas, or molecular clouds, in the constellations Perseus and Taurus.
The research team that discovered the cavity believes it may have been created when a star became supernova around 10 million years ago. This extraordinary stellar explosion has pushed gas out of the region, forming cavities and “Perseus-Taurus Supershell‘ of the stars that surround him.
“Hundreds of stars are either forming or already on the surface of this giant bubble,” said a postdoctoral researcher at Institute for Theory and Computation (ITC) from Center for Astrophysics (CfA), Shmuel Bialy, in a press release.
