A Magnitude 4.5 earthquake has just hit Yellowstone National Park and now, NASA is flying the world’s largest airborne observatory over this super-volcano. What’s going on?Continuous flybys of S.O.F.I.A. are taking place over Yellowstone super-volcano. The abbreviation, SOFIA, is for Stratospheric–Observatory for Infrared-Astronomy. It is the largest and most sensitive airborne observatory in the world.NASA only launches SOFIA if it’s really important. As one spokesperson said:”This Bird of Prey doesn’t go ‘hunting’ unless there is something to hunt. They are watching something, you can bet on it!”SOFIA’s 2.5-meter diameter infrared telescope makes it possible to perform scientific observations that are impossible for even the highest and largest ground telescopes. NASA has for several days been monitoring the sunrise/sunset, then flightradar 24 shows that they are also now monitoring Yellowstone National Park.
