| Giant sunspot, larger than Earth's diameter, appears on sun Posted: 07 Jan 2014 06:55 PM PST An enormous sunspot, labeled AR1944, slipped into view over the sun's left horizon late on Jan. 1, 2014. The sunspot steadily moved toward the right, along with the rotation of the sun, and now sits almost dead center, as seen in the image above from NASA's Solar Dynamics Observatory. |
| Pandora's magnifying glass: First image from Hubble's Frontier Fields Posted: 07 Jan 2014 02:09 PM PST This image of Abell 2744 is the first to come from Hubble's Frontier Fields observing program, which is using the magnifying power of enormous galaxy clusters to peer deep into the distant universe. Abell 2744, nicknamed Pandora's Cluster, is thought to have a very violent history, having formed from a cosmic pile-up of multiple galaxy clusters. |
| Out-of-this-world first light images emerge from Gemini Planet Imager Posted: 07 Jan 2014 02:09 PM PST After nearly a decade of development, construction and testing, the world's most advanced instrument for directly imaging and analyzing planets orbiting around other stars is pointing skyward and collecting light from distant worlds. |
| Stormy stars? Probing weather on brown dwarfs Posted: 07 Jan 2014 02:06 PM PST Swirling, stormy clouds may be ever-present on cool celestial orbs called brown dwarfs. New observations suggest that most brown dwarfs are roiling with one or more planet-size storms akin to Jupiter's "Great Red Spot." |
| Hubble unveils a deep sea of small and faint early galaxies Posted: 07 Jan 2014 01:37 PM PST Scientists have long suspected there must be a hidden population of small, faint galaxies that were responsible during the universe's early years for producing a majority of stars now present in the cosmos. At last Hubble has found them in the deepest ultraviolet-light exposures made of the early universe. This underlying population is 100 times more abundant in the universe than their more massive cousins that were detected previously. |
| Ultra-bright young galaxies discovered Posted: 07 Jan 2014 01:37 PM PST Astronomers have discovered and characterized four unusually bright galaxies as they appeared more than 13 billion years ago, just 500 million years after the big bang. Although Hubble has previously identified galaxies at this early epoch, astronomers were surprised to find objects that are about 10 to 20 times more luminous than anything seen previously. |
| Thousands of unseen, faraway galaxies discovered Posted: 07 Jan 2014 01:37 PM PST The first of a set of unprecedented, super-deep views of the universe contain images of some of the intrinsically faintest and youngest galaxies ever detected. This is just the first of several primary target fields in The Frontier Fields program. The immense gravity in this foreground galaxy cluster, Abell 2744, warps space to brighten and magnify images of far-more-distant background galaxies as they looked over 12 billion years ago, not long after the big bang. |
| Rare eclipsing double asteroid discovered Posted: 07 Jan 2014 06:33 AM PST Students in an undergraduate astronomy class made a discovery that wowed professional astronomers: a previously unstudied asteroid is actually a pair of asteroids that orbit and eclipse one another. Fewer than 100 binary eclipsing asteroids have been found in the main asteroid belt. |
| Stopping molecules with a centrifuge Posted: 07 Jan 2014 06:28 AM PST A novel deceleration technique brings fast continuous beams of polyatomic polar molecules almost to a halt. |
| NASA's Fermi makes first gamma-ray study of a gravitational lens Posted: 06 Jan 2014 04:01 PM PST Astronomers have made the first-ever gamma-ray measurements of a gravitational lens, a kind of natural telescope formed when a rare cosmic alignment allows the gravity of a massive object to bend and amplify light from a more distant source. |
| Faster method of boarding planes devised Posted: 06 Jan 2014 04:00 PM PST Researchers have come up with a new way to reduce the time it takes to board an airplane. Passengers are assigned to seats based on the amount of luggage they carry, distributing carry-ons evenly throughout the plane, resulting in a reduction in the total time to board all passengers. |
| New packaging plastic protects as well as aluminium foil Posted: 06 Jan 2014 10:29 AM PST Scientists have created an alternative stretchable plastic for prolonging shelf-life of pharmaceuticals, food and electronics. |
| Establishing guides for molecular counting using fluorescent proteins Posted: 06 Jan 2014 07:38 AM PST A study recently published has been able to determine the photoactivation efficiency of fluorescent proteins, an important parameter that has so far been difficult to measure at the single molecule level. |

| Eight million lives saved since Surgeon General's tobacco warning 50 years ago Posted: 07 Jan 2014 06:55 PM PST A new study estimates that 8 million lives have been saved in the United States as a result of anti-smoking measures that began 50 years ago this month with the groundbreaking report from the Surgeon General outlining the deadly consequences of tobacco use. |

| Snowball effect of overfishing highlighted Posted: 07 Jan 2014 01:37 PM PST Researchers have completed a major review of fisheries data that examines the domino effect that occurs when too many fish are harvested from one habitat. |
| Early sharks reared young in prehistoric river-delta nursery Posted: 07 Jan 2014 10:43 AM PST Like salmon in reverse, long-snouted Bandringa sharks migrated downstream from freshwater swamps to a tropical coastline to spawn 310 million years ago, leaving behind fossil evidence of one of the earliest known shark nurseries. |
| Cancer Statistics 2014: Death rates continue to drop Posted: 07 Jan 2014 07:26 AM PST An American Cancer Society report finds steady declines in cancer death rates for the past two decades add up to a 20 percent drop in the overall risk of dying from cancer over that time period. Progress has been most rapid for middle-aged black men. Nevertheless, black men still have the highest cancer incidence and death rates among all ethnicities in the US. |

| First dinosaurs identified from Saudi Arabia Posted: 07 Jan 2014 06:28 AM PST Dinosaur fossils are exceptionally rare in the Arabian Peninsula. Scientists have now uncovered the first record of dinosaurs from Saudi Arabia. What is now dry desert was once a beach littered with the bones and teeth of ancient marine reptiles and dinosaurs. A string of vertebrae from the tail of a huge "Brontosaurus-like" sauropod, together with some shed teeth from a carnivorous theropod represent the first formally identified dinosaur fossils from Saudi Arabia. |
