This discovery was made during a study by astronomers of how stars are formed, and they may have formed "after a supernova exploded in its core, pushing gas outward, forming this void," according to the interpretation of astrophysicist Shmuel Bialy.
The giant bubble was spotted in space as researchers analyze 3D maps of molecular clouds created using data from the European Space Agency's Gaia space probe.
The researcher added: "When a star dies, its supernova generates a chain of events that may eventually lead to the birth of new stars."
"Astronomers have tested these theoretical ideas using simulations in the past, but this is the first time we can use real 3D renderings to evaluate theories, down to the end result," he continued. According to the British newspaper "Daily Star".
