A pioneering infrared scan of 100,000 galaxies by Penn State astronomers has failed to detect any signs of galaxy-spanning extraterrestrial supercivilizations. This result, though very preliminary, may be a sign that aliens aren't capable of conquering entire galaxies.
For nearly three years, the Wide-field Infrared Survey Explorer (WISE) satellite was one of our most potent tools in the search for asteroids, discovering 33,500 of them (more than a dozen of which are potential impact threats) before being placed into hibernation in 2011. But with a new-found interest in asteroid…
Scientists have detected millions of previously hidden supermassive black holes surrounding us, some of them busily eating a thousand of newly discovered "extremely bright and extremely rare" galaxies called hot DOGs (Dust-Obscured Galaxies). Astronomy is fun!
This is Puppis A, the remnants of a violent supernova that exploded 3,700 years ago, glowing red as its shockwaves still heat up the dust around it. But Puppis A is really special because it hides the "Cosmic Cannonball."
Back in December, NASA launched the WISE, an infrared telescope that was designed to map the entire visible universe. And one of its first shots? This epic comet.
NASA just launched the new Wide-field Infrared Survey Explorer, or WISE, this morning. It'll be used to detect light- and heat-emitting objects that the Hubble might miss. Such as spaceships, I'll bet!!!
