The Power of Messier 82's Superwinds

  An international team of astronomers, led by Dr. Kazuya Matsubayshi (Kyoto University), has discovered that outflows of gas from starburst galaxy Messier 82 (see below) collide with a “cap” of gas clouds 40,000 light-years away from the galactic disk. Shockwaves (Note 1) from M82’s central starburst region are the most likely source of the [continue reading]

Fierce Galactic Winds from Starbursts End New Star Formation

  Fierce galactic winds powered by an intense burst of star formation may blow gas right out of massive galaxies, shutting down their ability to make new stars. Matter blasts out of the starburst galaxy M82 in this composite image from three observatories.
