July 14, 2015 — NASA's New Horizons spacecraft is at Pluto. After a decade-long journey through our solar system, New Horizons made its closest approach to Pluto Tuesday, about 7,750 miles above the surface -- ... read more

July 14, 2015 — NASA's New Horizons mission has answered one of the most basic questions about Pluto -- its size. Mission scientists have found Pluto to be 1,473 miles (2,370 kilometers) in diameter, somewhat ... read more

July 14, 2015 — A team of scientists participating in a radio astronomy summer school had the unexpected opportunity to observe a recently discovered near-Earth asteroid as it zipped past our planet on July ... read more

July 12, 2015 — According to a new study of more than 20,000 merging galaxies, when two different sized galaxies smash together, the larger galaxy stops the smaller one making new ... 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 — Two of NASA's heliophysics missions can now claim planetary science on their list of scientific findings. A group of scientists used the Venus transit -- a very rare event where a planet passes ... 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 9, 2015 — The first results have been released from a major new dark matter survey of the southern skies using ESO's VLT Survey Telescope (VST) at the Paranal Observatory in Chile. The VST KiDS survey ... read more

July 9, 2015 — The ghostly shells of galaxy ESO 381-12 are captured in a new image, set against a backdrop of distant galaxies. The strikingly uneven structure and the clusters of stars that orbit around the galaxy ... read more

July 9, 2015 — Radio astronomers are watching a previously dormant black hole wake up in a dramatic display as material falls on to it for the first time for perhaps millions of ... 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 7, 2015 — Almost 2000 exoplanets have been discovered to date, ranging from rocky Earth-like planets to hot-Jupiters, and orbiting every type of star. But how many of these distant worlds are habitable? ... read more

July 5, 2015 — A team of astronomers announced the discovery of a ring of rocks circling a very young star. This is the first time these 'pebbles', thought to be a crucial link in building planets, have ... read more

July 5, 2015 — Astronomers have found evidence for a large population of hidden supermassive black holes in the ... read more

July 5, 2015 — A wisp of cosmic radio waves, emitted before our solar system was born, shows that a new radio telescope will be able to detect galaxies other telescopes ... 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

July 2, 2015 — Researchers have begun a wide-area survey of the distribution of dark matter in the universe using Hyper Suprime-Cam, a new wide-field camera installed on the Subaru Telescope in ... read more

July 1, 2015 — There may be far fewer galaxies further out in the universe then might be expected, according to a new ... read more
