APOD 1.6 -- Galactic Winds
This image of M82 is a starburst galaxy. The large outflow of material from this galaxy old galaxy was caused by the common occurance of supernova, and the winds from large stars. Unlike most sharp images of space objects, this photograph was taken through the composite of many pictures taken by small earthbound telescopes. The Red fingerlings coming off the galaxy are caused by the hydrogen gas emissions, and the abundance of hydrogen in these regions of space are causing a burst of star formation, likely to continue for the next 100 million years. M82 is circumpolar in our region, as it is located in the northern region of Ursa Minor.
