A Magnetic Cigar

This is a composite image of the Cigar Galaxy (aka M82), a starburst galaxy about 12 million light-years away in the constellation Ursa Major. It combines visible starlight (gray) and a tracing of hydrogen gas (red) from the Kitt Peak Observatory, with near-infrared and mid-infrared starlight and dust (yellow) from SOFIA (a NASA telescope mounted on 747 which does infrared astronomy flying above most of the atmosphere) and the Spitzer Space Telescope.. A magnetic field detected by SOFIA shows up in the image as streamlines which seem to follow the outflows (red) generated by the burst of star formation in the nucleus of the galaxy.
