Earth is surrounded by a bubble of small stars from cosmic explosion

Did you know that Earth and our solar system are located inside a stellar bubble created by a cosmic explosion? The 1,000-light-year-wide cosmic bubble helped give birth to thousands of baby stars.

According to a new study with limited information, we have information about this “super bubble” — which suggests that 15 supernovae (star explosions) were responsible for the bubble.

Astronomers first discovered the bubble in 1970 and dubbed it a “local bubble.” They observed that no new stars were born inside the bubble in the past 14 million years. All the stars inside the bubble formed before it existed, or propagated here from outside the bubble — just like our own sun.

The cosmic explosion that created this bubble also ejected star-forming material such as hydrogen gas to its edges, turning the area outside this bubble into a nursery for baby stars.

The new study, published Jan. 12 in the journal Nature, claims that the localized bubble is not a uniform sphere, but resembles a random blob—representing the different supernovae that caused it. And it’s still expanding.

Shockwaves from the powerful supernova explosion formed “the dense crust that now forms the surface of the localized bubble,” NASA Hubble researcher Kathryn Zucker told LiveScience.
