- and MOUNTAIN VIEW,Calif., Jan. 14, 2021 /PRNewswire/ --What's fueling the massive ejection of gas and dust out of the Cigar galaxy, otherwise known at Messier 82?
- SOFIA, a joint project of NASA and the German Aerospace Center, DLR, previously studied the direction of magnetic fields close to the core of Messier 82, as the Cigar galaxy is officially known.
- These extended magnetic fields may help explain how gas and dust spotted by space telescopes have traveled so far away from the galaxy.
- Using SOFIA's existing observations of central magnetic fields, the research team modified this method to estimate the magnetic field 25,000 light-years around the Cigar galaxy.
