W44 is a supernova remnant 10,000 light years from our planet. Created by an exploding star, this majestic nebula is now the subject of research; a team of researchers led by Masaya Yamada of Keio University were initially investigating the amount of energy needed to give rise to the cloud of molecular gas, but instead – they found signs of a black hole living deep within its core.
Reported in the Astrophysical Journal Letters, the team showed interesting and unprecedented cloud formation within the nebula. The clouds motion and shape formed a “bullet” moving at over 100 times the speed of sound that can’t be explained by the presence of a supernova.
