Carving a Path

What looks like highways going through a metropolitan area are actually a series of glaciers carving their way through the Karakoram mountain range north of the Himalayas. This photograph was taken from the International Space Station as it orbited 263 miles above. via NASA https://ift.tt/skzaHpK

What created this unusual celestial firework? The nebula, dubbed Pa 30, appears in the same sky direction now as a bright “guest star” did in the year 1181. Although Pa 30’s filaments look similar to that created by a nova (for example GK Per), and a planetary nebula (for example NGC 6751), some astronomers now propose that it was created by a rare type of supernova: a thermonuclear Type Iax, and so is (also) named SN 1181. In this model, the supernova was not the result of the detonation of a single star, but rather a blast that occurred when two white dwarf stars spiraled together and merged. The blue dot in the center is hypothesized to be a zombie star, the remnant white dwarf that somehow survived this supernova-level explosion. The featured image combines images and data obtained with infrared (WISE), visible (MDM, Pan-STARRS), and X-ray (Chandra, XMM) telescopes. Future observations and analyses may tell us more. via NASA https://ift.tt/klQOzM8
