That's according to a new analysis — part of the biggest census of star - forming regions to date — that focused on stars eight times the mass of our sun or larger (the size that eventually explode as supernovae) at a very early stage in their lifetime, when they'd still be inside the clouds of gas and dust where they formed.
According to the popular «collapsar» theory, a GRB occurs when a very massive star explodes as a supernova and collapses into a black hole.

At the end of its life, a massive star inevitably explodes as a supernova.
These neighbouring bubbles eventually merged to form a superbubble, and the short life spans of the stars at its heart meant that they exploded as supernovae at similar times, expanding the superbubble even further, to the point that it merged with other superbubbles, which is when the supershell was formed.
Sobral adds: «But star formation at this rate leads to a lot of massive, short - lived stars coming into being, which explode as supernovae a few million years later.
