Jose Emilio Castellanos

The most recent supernova in our galaxy has been discovered by tracking the expansion of its explosion debris. The information was released by NASA, and it states that it used the observatory's telescopes Chandra and Very Large Array.

The supernova explosion, registered less than a century and a half turns, so far, the most recent in the Milky Way. Previously, the last known supernova in our galaxy occurred around 1680.

A supernova or star new "is a stellar explosion that produces very bright objects on the celestial sphere. owes its name often appeared where previously not seen anything.

Supernovae expand upon heating and expel large amounts of gases around it. In some cases may trigger new star formation within the cycle of stellar birth and death, and can cause the formation of a neutron star or black hole.
