A new study reveals that our planet resides on the surface of the 'Local Bubble,' a cavity of cold gas and dust that formed our sun and other nearby stars.
” a 1,000-light-year-wide cavity of cold gas and dust that’s responsible for the formation of all nearby young stars—including our sun.
“Essentially we have a front-row seat to the all star formation that’s happening on the surface all around us,” Zucker says. But while astronomers have known about the Local Bubble for decades, this discovery wasn’t years in the making. In fact, it was an accident. , turned into a fantastic revelation after the team noticed that stars seemed to be unifying near the bubble’s surface.By using a software program called Glue and data from the space observatory Gaia to create a map of where exactly these stars lie, Zucker’s team was able to determine that the bubble’s origin stems from a series of supernovae explosions that date back about 14 million years ago.
