A space explosion is a gamma-ray burst. A
gamma-ray burst is a short-lived burst of
gamma-ray protons. We don't know what causes them
and you can't see them with the naked eye. Some
of these explosions are associated with a special
type or supernovae, which are the explosions
marking the deaths of especially massive stars.
But gamma-ray bursts are the most powerful
explosions the Universe has seen since the Big
Bang. They occur approximately once per day and
are brief, but intense, and last from a few
milliseconds to a few hundred seconds.
Well, I think a general definition would be that a
space explosion is a "rapid" and/or large release
of energy -ultimately gravitational potential
energy.There are several mechanisms that can cause
explosions. One recent one that was in the
an observation of an "explosion" due to a lot of
matter falling into a super massive black hole at
the center of a galaxy. As the matter falls into
the black hole it releases energy which drives the
explosion, somewhat similar to a big meteor
falling onto/crashing into the Earth which I guess
would be another type of space explosion.
Supernovae are also a type of explosion where the
core of a star collapses under its own weight and
explodes. Can you think of any other types of
