NASA astrophysicist Elizabeth Hayes, the project scientist of the Fermi Gamma-ray Space Telescope, described it as a white dwarf star devouring so much of its companion star that it reaches a critical threshold resulting in a thermonuclear explosion on its surface. When that happens, they expect we’ll be able to see it above the western horizon when it temporarily becomes as bright as any star in the Big Dipper. A tiny dinosaur used wings to run fast, and possibly to fly106 million years ago, in what is now South Korea, a bird-like dinosaur with wings ran across a muddy flat and left behind tiny footprints.
