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

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

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 — 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

June 23, 2015 — Astronomers have solved a mystery over small, unusually hot blue stars, 10 times hotter than our Sun, that are found in the middle of dense star ... read more

June 23, 2015 — To find life in the universe, it helps to know what it might look like. If there are organisms on other planets that do not rely wholly on photosynthesis -- as some on Earth do not -- how might those ... read more

June 22, 2015 — The interiors of several of our Solar System's planets and moons are icy, and ice has been found on distant extrasolar planets, as well. This ice must exist under extreme pressures and ... read more

June 22, 2015 — If planets had personalities, Mars would be a rock star according to recent preliminary results from NASA's MAVEN spacecraft. Mars sports a 'Mohawk' of escaping atmospheric particles ... read more

June 22, 2015 — Astronomers have discovered 854 "ultra-dark galaxies" in the Coma Cluster. The new discovery surpasses the 2014 discovery of 47 mysterious dark galaxies by more than 800 and suggests that ... read more

June 22, 2015 — Astronomers have successfully commissioned a new type of optic that can reveal the image of an exoplanet next to its parent star. The 'vector Apodizing Phase Plate' (vector-APP) coronagraph ... read more

June 22, 2015 — Astronomers have determined the mass of a tiny binary star thanks to its intense radio emissions – rare in such small stars – which compels scientists to review stellar evolution ... read more

June 20, 2015 — Saturn's moon Titan is home to seas and lakes filled with liquid hydrocarbons, but what forms the depressions on the surface? A new study suggests the moon's surface dissolves in a process ... read more
