July 27, 2015 — Astronomers have long known that powerful cosmic winds can sometimes blow through galaxies, sweeping out interstellar material and stopping future star formation. Now they have a clearer snapshot of ... read more

July 23, 2015 — Scientists have engaged in a unique study of potentially destructive high-energy electrons streaking into Earth's atmosphere from space, for the first time employing two distinctly different and ... read more

July 22, 2015 — A new theory says dark matter acts remarkably similar to subatomic particles known to science since the ... read more

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

July 14, 2015 — In the 1960s, NASA launched six satellites to study Earth's atmosphere, magnetosphere and the space between Earth and the moon. Using observations from those satellites, researchers have ... read more

July 10, 2015 — Five billion years ago, a great disturbance rocked a region near the monster black hole at the center of galaxy 3C 279. On June 14, the pulse of high-energy light produced by this event finally ... read more

July 9, 2015 — What looks like a shooting target is actually an image of nested rings of X-ray light centered on an erupting black hole. On June 15, NASA's Swift satellite detected the start of a new outburst ... read more

July 8, 2015 — Observations have for the first time demonstrated a link between a very long-lasting burst of gamma rays and an unusually bright supernova explosion. The results show that the supernova was not ... read more

July 8, 2015 — Turbulent processes take place close to supermassive black holes, which lurk in the centers of nearly all galaxies. They swallow up matter flowing in from the outside while at the same time producing ... 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

July 6, 2015 — A ring of dust 200 light years across and a loop covering a third of the sky: two of the results in a new map from the Planck ... read more

July 2, 2015 — Astronomers are gearing up for high-energy fireworks coming in early 2018, when a stellar remnant the size of a city meets one of the brightest stars in our ... read more

NASA Missions Monitor a Waking Black Hole

June 30, 2015 — NASA's Swift satellite detected a rising tide of high-energy X-rays from the constellation Cygnus on June 15, just before 2:32 p.m. EDT. About 10 minutes later, the Japanese experiment on the ... 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
