Hubble Unveils Cosmic 'Bullets' Fired at 20 Million MPH from a Unique Stellar Explosion
Astronomers, using the Hubble Space Telescope and other instruments, have peered through decades of cosmic dust to uncover the secrets of V445 Puppis, the Milky Way's only known 'helium nova'. This rare stellar explosion, which erupted in 2000, is now revealing unprecedented 'cosmic bullets' of gas traveling at astounding speeds, alongside a unique binary star system. The discovery offers crucial insights into Type Ia supernovae and could signal a potential repeat eruption, furthering our understanding of the universe's expansion.
