An anonymous reader writes "This week marks the sixteenth anniversary of the launch of Hubble Space Telescope. 'To celebrate [...] NASA and the European Space Agency (ESA), are releasing this image of the magnificent starburst galaxy, Messier 82 (M82). This mosaic image is the sharpest wide-angle view ever obtained of M82. The galaxy is remarkable for its bright blue disk, webs of shredded clouds, and fiery-looking plumes of glowing hydrogen blasting out of its central regions.' Wired News also has some nice additional images."
