Cigar Galaxy or M82
The fumes red of the Cigar galaxy

To celebrate 16 years of success, the Hubble Space Telescope, the two space agencies, NASA and European Space Agency (ESA), released this beautiful image of the irregular galaxy, Messier 82 (M82) also called, the cigar galaxy. In the center of this galaxy there is a huge concentration of young stars embedded in gas and dust. The super galactic winds generated by these stars compresses enough gas to give rise to even greater star. In M82, young stars are crammed into tiny clusters of stars, but massive. These masses congregate by the dozens and emit light output as "lumps" in the central part of M82. Clusters can not be distinguished in this Hubble image. Most objects pale and white, who sprinkle the area around M82 that look like fuzzy stars are actually individual star clusters about 20 light years in diameter. These clusters can contain up to one million stars. The rapid pace of star formation in this galaxy, finally undergoes his own restraint. When star formation becomes too intense, it will consume and destroy the material needed to make more stars. The twinkling stars, will die, probably within a few tens of millions of years.
Located 12 million light years away, M82 appears high in the air spring in the north in the direction of the constellation Ursa Major. If it is called the "Cigar Galaxy", is due to the elliptical shape produced by the oblique tilt of its starry disk. The images were captured in March 2006 with the Advanced Camera for Surveys' Wide Field Channel. Astronomers have assembled this mosaic of six composite images by combining exposures taken with four colored filters that capture starlight from visible wavelengths and infrared as well as the light of glowing hydrogen filaments.

The cigar in the infrared
Cigar galaxy was once considered an irregular galaxy.
No theory could explain the observed data, although it was suggested that the object could be a "micro-quasar", with very high brightness fairly stable.
