M82, also known as the Cigar Galaxy thanks to its distinctive shape, is a familiar target for amateur and professional astronomers alike, the closest starburst galaxy to Earth at a distance of some 12 million light years. Located in the constellation Ursa Major, M82’s core is 100 times brighter than the Milky Way’s, the result of rapid star formation likely triggered by gravitational interactions with the nearby galaxy M81. In this composite view, M82’s magnetic field, detected by the High-resolution Airborne Wideband Camera-Plus instrument aboard the SOFIA airborne observatory, is shown as streamlines that appear to follow bipolar outflows of gas, seen in red, generated by starburst activity. Visible starlight is shown in grey, with near- and mid-infrared starlight and dust shown in yellow as seen by the SOFIA and the Spitzer Space Telescope.
This NASA/ESA Hubble Space Telescope image reveals the glittering interior of one of the most active galaxies in our local neighbourhood — NGC 1569, a small starburst galaxy located about eleven million light-years away in the northern constellation of Camelopardalis. For almost 100 million years, NGC 1569 has pumped out stars over 100 times faster than the Milky Way.
An international team led by a researcher from Hiroshima University has succeeded in revealing the detailed structure of a massive ionised gas outflow streaming from the starburst galaxy NGC 6240, 350 million light-years away in the constellation Ophiuchus. The team used the Suprime-Cam mounted on the 8.2-metre Subaru Telescope on Maunakea in Hawaii.
