This is the Cigar Galaxy (also called M82), a starburst galaxy about 12 million light-years away in the constellation Ursa Major.
Using our @SOFIATelescope observatory, researchers found the galactic wind flowing from the Cigar Galaxy weighs quite a lot: it carries the equivalent mass of 50 to 60 million Suns in gas and dust! Aligned along a magnetic field, the wind transports these materials into intergalactic space.
The magnetic field is shown as streamlines in this composite image, which combines 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 and the Spitzer Space Telescope.
