Astronomers discover that a supernovae explosion 14 million years ago initiated a chain of events responsible for the formation of all nearby, young stars.
The solar system lies inside a structure called the Local Bubble that is some 1000 light years across – and a map of its surface shows it is the site of star formation
Scientists have shown how a chain of events led to the creation of the vast bubble that is responsible for the formation of all young stars within 500 light-years of the sun and Earth.
