Explanation:
The explosion is over, but the consequences continue.
About eleven thousand years ago, a star in the constellation of
Vela could be seen to
explode,
creating a strange point of light briefly visible to
humans living near the beginning of
recorded history.
The outer layers of the star crashed into the
interstellar medium, driving a
shock wave that is still visible today.
The
featured image
captures some of that filamentary and gigantic shock in
visible light.
As gas flies away from the detonated star, it
decays and reacts with the interstellar medium,
producing light in many different colors and energy bands.
Remaining at the center of the
Vela Supernova Remnant is a
pulsar, a star as dense as nuclear matter that
spins around
more than ten times in a single second.
