Science Is Good on Instagram: "NASA’s Kepler mission made a groundbreaking discovery: the Kepler 47 system, the first known planetary system where multiple planets orbit a pair of stars. Located 4,900 light-years away, this discovery proves that more than one planet can form and persist in the gravitationally stressful environment of a binary star. This system hosts two planets: Kepler 47b, a sweltering inner world, and Kepler 47c, an outer gaseous giant slightly larger than Neptune. Crucially,

Supernova remnants, the debris fields left behind after a stellar explosion, often glow strongly in X-ray light because the material has been heated to millions of degrees from the blast. The remnant is located in our galaxy, about 17,000 light-years from Earth, allowing Chandra to make detailed images of the debris and how it changes with time. This latest video
