A cavity in space

Post by brian livesey »

A huge “cavity” discovered in space might add new information about star formation. Measuring almost 500 light-years the void is located in Perseus and Taurus. Astrophysicists suspect that the feature was formed by supernovae around 10 million years ago.
Samuel Bialy, of the Institute of Theory and Computation at the Centre for Astrophysics, Harvard and Smithsonian, who led the research, said: “Hundreds of stars are forming or exist already at the surface of this giant bubble. ... “We have two theories: either one supernova went off at the core of this bubble and pushed gas outward ... or a series of supernovae occurring over millions of year created it over time. ... “This demonstrates that when a star dies, it’s supernova generates a chain of events that may ultimately lead to the birth of new stars.”
