1,000-LIGHT-YEAR-WIDE BUBBLE SURROUNDING EARTH IS SOURCE OF ALL NEARBY, YOUNG STARS
Hey, Space Placers! Artist's illustration of the Local Bubble with star formation occurring on the bubble's surface. Scientists have now shown how a chain of events beginning 14 million years ago with a set of powerful supernovae led to the creation of the vast bubble, responsible for the formation of all young stars within 500 light-years of the Sun and Earth.
