(ORDO NEWS) — In the Milky Way, experts have discovered a huge cavity, which they named the “Perseus-Taurus Superbubble”. Most likely, it originated about 10 million years ago.
Scientists have used data from ESA‘s Gaia Space Observatory to create detailed 3D maps of molecular clouds that are in close proximity to the Sun.
After that, they conducted a thorough analysis, which showed the presence of a spherical cavity of enormous size. Its length is almost 500 years. the results of the study were published in the scientific journal Astrophysical Journal Letters.
Shmuel Biali told that molecular clouds of Taurus and Perseus are located around the cavity. They contain many young stars that are still at the stage of their formation.
Scientists have two theories of how such a cavity could have formed. It could have been a single supernova explosion that pushed huge amounts of gas outward. If the formation of the cavity occurred gradually, then there were several supernova explosions and they occurred at different times.
Such a discovery may prove the fact that the molecular clouds of Taurus and Perseus are far from independent cosmic structures. They could have formed simultaneously as a result of the influence of a single shock wave resulting from a supernova explosion.
