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.

The waning of a gibbous Moon

The waning gibbous Moon lies between Jupiter and Aldebaran tonight, rising from the north-east in late evening.

A Gibbous Moon
A gibbous moon is one of the phases of the Moon, when the size of the illuminated portion is greater than half but not a full Moon.

The period between a first quarter moon and a full moon is known as a waxing gibbous moon, because the illuminated region of the Moon is increasing from day to day. 

After it becomes a full moon, but hasn’t reached the last quarter, the Moon is called a waning gibbous moon.

Alderban
Aldebaran (Alpha Tauri) is a red giant star located about 65 light years away in the zodiac constellation of Taurus.
