July 2, 2015 — Space debris poses a growing threat to satellites and other spacecraft, which could be damaged in the event of a collision. A new German space surveillance system, schedudled to go into operation in ... read more

July 1, 2015 — The European Space Agency's Rosetta spacecraft first began orbiting comet 67P/Churyumov-Gerasimenko in August 2014. Almost immediately, scientists began to wonder about several surprisingly ... read more

July 1, 2015 — Astronomers have confirmed the existence of a young giant gas planet still embedded in the midst of the disk of gas and dust surrounding its parent star. For the first time, scientists are able to ... read more

July 1, 2015 — This rich view of an array of colorful stars and gas was captured by the Wide Field Imager camera, on the MPG/ESO 2.2-meter telescope at ESO's La Silla Observatory in Chile. It shows a young ... read more

June 30, 2015 — Mathematicians and physicists have come up with a new approach to calculate cosmic viscosity and the formulation favors the 'Big Rip' scenario for the end of the ... read more

June 30, 2015 — Researchers are determining if a key rocket component can withstand the rigors of the next generation of space flight. The parts in question — bellows expansion joints — serve several functions ... read more

Cheek Muscles Hold Up Better Than Leg Muscles in Space

June 30, 2015 — Muscles need gravity to maintain optimal health, and when they do not have it, they deteriorate. A new report, however, suggests that this might not be true for all muscles, offering hope that there ... read more

June 30, 2015 — Type Ia supernovae are the 'standard candles' astrophysicists use to chart distance in the Universe. But are these dazzling exploding stars truly all the same? To answer this, scientists ... read more

June 29, 2015 — 33 Kepler stars have been selected for their solar like oscillations and a set of basic parameters have been determined with high precision showing that stars even older than 11 billion years have ... read more

June 29, 2015 — Astronomers have created all-sky image maps and released the full database to researchers. Far-infrared light is the key wavelength range for investigating the formation processes of stars and ... read more

June 26, 2015 — Researchers have found evidence that enigmatic objects in nearby galaxies -- called ultra-luminous X-ray sources (ULXs) -- exhibit strong outflows that are created as matter falls onto their black ... read more

June 26, 2015 — Experiments at Sandia's Z machine have provided data may help explain why Saturn is two billion years younger than Jupiter on some computer simulations, supporting a prediction first made in ... read more

June 26, 2015 — New work offers a potential solution to a longstanding problem in the prevailing theory of how rocky planets formed in our own Solar System, as well as in others. The snag he's untangling: how ... read more

June 25, 2015 — A new supercomputer simulation of the planet and debris disk around the nearby star Beta Pictoris reveals that the planet's motion drives spiral waves throughout the disk, a phenomenon that ... read more

June 25, 2015 — The giant elliptical galaxy Messier 87 has swallowed an entire medium-sized galaxy over the last billion years. For the first time a team of astronomers has been able to track the motions of 300 ... read more

June 24, 2015 — Astronomers have analyzed the clouds of gas and dust from some of the earliest galaxies ever observed -- one billion years after the Big ... read more

June 24, 2015 — Astronomers have discovered an immense cloud of hydrogen dispersing from a warm, Neptune-sized planet orbiting a nearby star. The enormous comet-like tail of the planet is about 50 times the size of ... read more

June 24, 2015 — Active galactic nuclei are the brightest objects in the universe. They are not lit up permanently, but rather 'flicker' extremely slowly. This insight helps researchers better understand ... read more

June 23, 2015 — In late 2013, when the neutron star at the heart of one of our galaxy's oddest supernovae gave off a massive burst of X-rays, the resulting echoes -- created when the X-rays bounced off clouds ... read more

June 23, 2015 — A new computer simulation shows that dark matter particles colliding in the extreme gravity of a black hole can produce strong, potentially observable gamma-ray light. Detecting this emission would ... read more
