July 20, 2015 — A new investigation has found radiation from solar events is too weak to cause worry at ground ... read more

July 8, 2015 — X-rays light up the surface of our Sun in a bouquet of colors in this new image. The high-energy X-rays seen by NuSTAR are shown in blue, while green represents lower-energy X-rays from the X-ray ... 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 — 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 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 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 18, 2015 — A new image shows a gathering of four cosmic companions. This quartet forms part of a group of galaxies known as the Hickson Compact Group 16, or HCG 16 -- a galaxy group bursting with dramatic star ... read more

June 18, 2015 — Scientists have observed how a widespread polar wind is driving gas from the atmosphere of Saturn's moon Titan. The team analyzed data gathered over seven years by the international Cassini ... read more

May 28, 2015 — Astrophysicists have developed a new method for calculating the effect of Rayleigh scattering on photons, potentially allowing researchers to better understand the formation of the ... read more

May 27, 2015 — Using ever more energetic lasers, researchers have produced a record high number of electron-positron pairs, opening exciting opportunities to study extreme astrophysical processes, such as black ... read more

May 27, 2015 — Astronomers have discovered for the first time a rear-end collision between two high-speed knots of ejected matter from a supermassive black hole. This discovery was made while piecing together a ... read more

May 27, 2015 — In the brightest region of this glowing nebula called RCW 34, gas is heated dramatically by young stars and expands through the surrounding cooler gas. Once the heated hydrogen reaches the borders of ... read more

May 20, 2015 — Astronomers using ESO's Very Large Telescope in Chile have captured the most detailed image ever taken of the Medusa Nebula. As the star at the heart of this nebula made its transition into ... read more

May 14, 2015 — The discovery of a 'left-handed' magnetic field that pervades the universe could help explain a long standing mystery -- the absence of cosmic ... read more

May 11, 2015 — The underlying physical process that creates striking 'breaking wave' cloud patterns in our atmosphere also frequently opens the gates to high-energy solar wind plasma that perturbs ... read more

May 3, 2015 — A group of unusual giant black holes may be consuming excessive amounts of matter, according to a new study. This finding may help astronomers understand how the largest black holes were able to grow ... read more

May 1, 2015 — What happens to an astronaut's brain during a mission to Mars? Nothing good. It's besieged by destructive particles that can forever impair cognition, according to a radiation oncology ... read more
