M82: Galaxy with super galactic wind

 Why is the Cigar Galaxy billowing red smoke? M82, as this starbuster Galaxy is also known,was stirred up by a recent pass near large spiral galaxy M81. This doesn't fully explained the source of the red glowing outwardly expanding gas and dust, however. 

Evidences indicates that this gas and dust is begin driven out by the combined emerging particle winds of many stars, together creating a galactic super wind. The dust particles thought to originate in M82' s interstellar medium and are actually similar in size to particles in Cigar smoke.

The featured photographic mosaic highlights a specific colour of red light strongly emitted by ionized hydrogen gas, showing detailed filaments of this gas and dust. The filaments extends for over 10,000 light years. The 12 million light years distant, Cigar Galaxy is the brightest galaxy in the sky in infrared light, and can be seen in visible light with a small telescope towards the constellation of the Great Bear ( Ursa Major ).
