| Cosmic illusion revealed: Gravitational lens magnifies supernova Posted: 24 Apr 2014 11:36 AM PDT Astronomers have announced the discovery of a galaxy that magnified a background, Type Ia supernova thirty-fold through gravitational lensing. This first example of strong gravitational lensing of a supernova confirms the team's previous explanation for the unusual properties of this supernova. |
| Astronomical forensics uncover planetary disks in NASA's Hubble archive Posted: 24 Apr 2014 11:09 AM PDT Astronomers using NASA's Hubble Space Telescope have applied a new image processing technique to obtain near-infrared scattered light photos of five disks observed around young stars in the Mikulski Archive for Space Telescopes database. These disks are telltale evidence for newly formed planets. |
| Equipped with new sensors, Morpheus preps to tackle landing on its own Posted: 24 Apr 2014 08:27 AM PDT A test flight later this week will challenge a set of sensors to map out a 65-yard square of boulder-sized hazards and pick out a safe place to land. Mounted to an uncrewed prototype lander called Morpheus that flies autonomously several hundred feet above the ground, the sensor system will have 10 seconds to do its work: six seconds really, as it will take four seconds to map the area before choosing a landing site. The sensor system is a 400-pound set of computers and three instruments called ALHAT, short for Autonomous Landing and Hazard Avoidance Technology. |
