The Messier 82 (M82) is an imposing galaxy because of its areas of clouds and columns like flames caused by hydrogen explosions outside the central regions. M82 is in the northern sky, near the constellation Ursa Major, the Big Dipper, 12 million light years from Earth. It is also known as the 'Cigar Galaxy'. Its elliptical elongated shape is produced by the inclination of its star discs.
The M82 is a magnificent galaxy with many stars. Along its central region young stars begin to be born ten times faster than those inside the Milky Way. These hot new stars not only emit radiation but also charged particles, which form the so-called stellar wind. The waves of stellar winds of these stars combine to form a galactic 'wind'.
The wind compresses enough gas to activate the ignition of millions of other stars and launch bursts of clouds of hydrogen ionized hot gas, above and below the galactic disk.
