Astronomers Found Mysterious Gas 'Bullets' Racing Out of the Milky Way’s Rarest Stellar Explosion

Hubble telescope watches unique nova explosion fire cosmic 'bullets' through the Milky Way at 20 million mph

Using NASA's long-serving Hubble Space Telescope, astronomers have discovered that a stellar explosion in the Milky Way is blasting out cosmic bullets travelling at 20 million miles per hour.The cosmic explosion in question is V445 Puppis, which erupted in 2000 and is the only known "helium nova" in our galaxy. Though astronomers have been studying V445 Puppis for two decades, much of the phenomena associated with it were shrouded in mystery due…

Rare Star Blast Fires Cosmic Gas Bullets Across Space At 20 Million MPH

Astronomers have used the Hubble Space Telescope to capture cosmic 'bullets' streaming from V445 Puppis, a unique stellar explosion in the Milky Way firing clumps of gas into space at a blistering 20 million miles per hour. When V445 Puppis erupted in late 2000, it instantly stood out as the only confirmed helium nova ever detected within
