July 20, 2015 — Planet Earth is situated in what astronomers call the Goldilocks Zone -- a sweet spot in a solar system where a planet's surface temperature is neither too hot nor too cold. An ideal distance ... read more

July 20, 2015 — The National Science Foundation's Green Bank Telescope will join in the most powerful, comprehensive, and intensive scientific search ever for signs of intelligent life in the ... read more

July 15, 2015 — Sibling suns -- made famous in the "Star Wars" scene where Luke Skywalker gazes toward a double sunset -- and the planets around them may be more common than we've thought, and ... read more

July 15, 2015 — So far, exoplanet surveys have been most sensitive to planetary systems that are populated in their inner regions by massive planets, down to a few times the mass of the Earth. This contrasts with ... read more

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
