When galaxies interact gravitationally, one of the consequences can be a burst of star formation. One such "star burst galaxy," is M82. M82 is five times brighter than our galaxy, with a center that is a hundred times brighter than that of our galaxy. Like Bode's Galaxy, M82 was also discovered by Johann Bode. The Hubble Space Telescope discovered almost 200 starbirth regions in M82's core, each with an average of around 200,000 solar masses.
This image was taken with the same platform as that used to image M81. This is a stack of 34 x 20s images.
The trials, tribulations and small triumphs of a Charlotte, NC astronomer imaging under Bortle 8/9 skies.
