Feb. 18, 2016 Incredibly dense and powerful objects beyond our Milky Way Galaxy may prevent the escape of high-energy gamma rays that accompany the production of the cosmic neutrinos detected on Earth by the ... read more Feb. 17, 2016 Astronomers have discovered a new source that confirmed the fact that binary systems with strong colliding stellar winds comprise a separate new population of high-energy gamma-ray ... read more Feb. 17, 2016 For two decades it was thought that most near-Earth objects (NEOs) -- asteroids and comets that may pose a hazard to life on Earth -- end their existence in a dramatic final plunge into the Sun. A ... read more Dynamical Systems Theory Enhances Knowledge of Jupiter's Atmosphere Feb. 17, 2016 Scientists use video footage to analyze Jupiter's transport barriers and examine prior conclusions about Jupiter's ... read more Feb. 16, 2016 The first successful detection of gases in the atmosphere of a super-Earth reveals the presence of hydrogen and helium, but no water vapor. The exotic exoplanet, 55 Cancri e, is over eight times the ... read more Feb. 13, 2016 Using ALMA, astronomers have taken a new, detailed look at the very early stages of planet formation around a binary star. Embedded in the outer reaches of a double star's protoplanetary disk, ... read more Feb. 12, 2016 University of Washington astronomers have identified a rare type of supernova 'impostor' in a nearby galaxy, with implications for how scientists look at the short, complex lives of massive ... read more Feb. 11, 2016 A first-ever computer simulation shows that, contrary to previous understandings, objects approaching a rotating black hole would not be crushed by the increasing gravity -- supporting some popular ... read more Feb. 11, 2016 The placid appearance of NGC 4889 can fool the unsuspecting observer. But the elliptical galaxy, seen in a new image from the NASA/ESA Hubble Space Telescope, harbors a dark secret. At its heart ... read more Feb. 10, 2016 A newly formed star lights up the surrounding clouds in this new image from ESO's La Silla Observatory in Chile. Dust particles in the vast clouds that surround the star HD 97300 diffuse its ... read more Feb. 9, 2016 Hundreds of hidden nearby galaxies have been studied for the first time, shedding light on a mysterious gravitational anomaly dubbed the Great Attractor. Despite being just 250 million light years ... read more Feb. 8, 2016 Messages from around the world are to be beamed into space at the speed of light as part of a cultural project to create a celestial time ... read more Feb. 5, 2016 Stars do not accumulate their final mass steadily, but in a series of violent events manifesting themselves as sharp stellar brightening. Stellar brightening can be caused by fragmentation due to ... read more Feb. 4, 2016 Astrophysicists are using new methods to simulate the common-envelope phase of binary stars, discovering dynamic irregularities that may help to explain how supernovae ... read more Feb. 4, 2016 Astronomers have revealed the detailed structure of a massive ionized gas outflow streaming from the starburst galaxy NGC 6240. The light-collecting power and high spatial resolution of Subaru ... read more New Study Challenges Jupiter's Role as Planetary Shield, Protecting Earth from Comet Impacts Feb. 3, 2016 Not only is the 'Jupiter as shield' concept, implying that the planet shields Earth from comet impacts, not true, but perhaps Jupiter's most important role in fostering the development ... read more Feb. 3, 2016 Studies by two independent groups from the US and the Netherlands have found that gamma ray signals from the inner galaxy come from a new source rather than from the collision of dark matter ... read more Bright Sparks Shed New Light on the Dark Matter Riddle Feb. 1, 2016 The origin of matter in the universe has puzzled physicists for generations. Today, we know that matter only accounts for 5 percent of our universe; another 25 percent is constituted of dark matter. ... read more Jan. 30, 2016 Scientists have turned to a combination of real time observations and computer simulations to best analyze how material courses through the ... read more Jan. 29, 2016 Promising new calibration tools, called laser frequency combs, could allow astronomers to take a major step in discovering and characterizing earthlike planets around other stars. These devices ... read more
