STELLAR THIEF IS THE SURVIVING COMPANION TO A SUPERNOVA
Companion to a Supernova is No Innocent Bystander In the fading afterglow of a supernova explosion, astronomers using NASA's Hubble Space Telescope have photographed the first image of a surviving companion to a supernova. This is the most compelling evidence that some supernovas originate in...

Kepler Solves Mystery of Fast and Furious Explosions
Space Observatory Captures the Details of an Unusual Stellar Detonation The universe is so huge that it's estimated that a star explodes as a supernova once every second. Astronomers capture a small fraction of these detonations because they are comparatively short-lived, like fireflies...

Dark Matter Goes Missing in Oddball Galaxy
Galaxy was expected to contain 400 times more dark matter than observations show Grand, majestic spiral galaxies like our Milky Way are hard to miss. Astronomers can spot these vast complexes because of their large, glowing centers and their signature winding arms of gas and dust, where...

COMPARISON OF A MODEL OF A BLUE SUPERGIANT’S SPECTRUM WITH OBSERVATIONAL DATA
Scientists found that the Hubble data from MACS J1149+2223 Lensed Star 1 (Icarus) matches the model for a blue supergiant. The agreement shows a remarkably good fit, and indicates that Icarus is approximately twice as hot as the Sun. The solid blue line shows the model spectrum of the blue...

Hubble Uncovers the Farthest Star Ever Seen
Cosmic Quirk Boosts Far-Off Star’s Faint Glow Through a quirk of nature called “gravitational lensing,” a natural lens in space amplified a very distant star’s light. Astronomers using Hubble took advantage of this phenomenon to pinpoint the faraway star and set a new distance record for the...
