Simeis 147: Supernova Remnant 3000 light years away

Seen here is Simeis 147, the remains of a supernova 3000 light years away, which can be seen in the sky near Taurus

Forty thousand years ago, a massive star exploded as a supernova.

It left behind this debris, which is colliding with dust and gas as it continues to expand.
