M82: Galaxy with a supergalactic wind

This galaxy is informally known as the "cigar galaxy". It is 12 million light years away. It is also classified as an irregular galaxy, its shape being elliptical. A spiral galaxy passing by has recently stirred up the cigar galaxy. There is a red glowing gas that is seemingly being omitted from this strange galaxy. Particle winds from multiple stars are combining to form what is called a superwind. It can be seen using a telescope when looking toward Ursa Major. This red glow is created by ionized hydrogen and it extends about 10,000n light years from the galaxy. When the night sky is looked at using infrared light, this glaxy shows up to be the brightest galaxy.
