Dec. 7, 2018 — The first unbiased survey of protoplanetary disks surrounding young stars in the Taurus star-forming region turned up a higher-than-expected number of disks with features suggesting nascent planets, ... read more

Dec. 6, 2018 — Although helium is a rare element on Earth, it is ubiquitous in the universe. It is, after hydrogen, the main component of stars and gaseous giant planets. Despite its abundance, helium was only ... read more

Dec. 5, 2018 — The Earth formed relatively quickly from the cloud of dust and gas around the Sun, trapping water and gases in the planet's mantle, based on neon isotopes from the depths of the Earth and deep ... read more

Dec. 3, 2018 — Astronomers using a combination of ground and space based telescopes have reported more than 100 extrasolar planets (exoplanets) in only three months. These planets are quite diverse and expected to ... read more

Nov. 21, 2018 — New research from astronomers gives updated climate models for the seven planets around the star TRAPPIST-1. The work also could help astronomers more effectively study planets around stars unlike ... read more

Nov. 20, 2018 — New observations of a young gas giant demonstrate the power of a ground-based method for searching for signatures of ... read more

Nov. 14, 2018 — The nearest single star to the Sun hosts an exoplanet at least 3.2 times as massive as Earth -- a so-called super-Earth. One of the largest observing campaigns to date using data from a world-wide ... read more

Oct. 31, 2018 — After nine years in deep space collecting data, NASA's Kepler space telescope has run out of fuel needed for further science operations. NASA has decided to retire the spacecraft within its ... read more

Oct. 24, 2018 — Researchers have discovered that compact, multiple-planet systems are more likely to form around stars that have lower amounts of heavy elements than our own ... read more

Oct. 18, 2018 — Flares from the youngest red dwarfs surveyed are 100 to 1,000 times more energetic than when the stars are older. This younger age is when terrestrial planets are forming around their ... read more

Oct. 17, 2018 — Astrophysicist now have a way of finally telling whether newly forming planets are migrating within the disc of dust and gas that typically surrounds stars or whether they are simply staying put in ... read more

Oct. 15, 2018 — Researchers have identified a young star with four Jupiter and Saturn-sized planets in orbit around it, the first time that so many massive planets have been detected in such a young system. The ... read more

Oct. 3, 2018 — On the hunt for distant worlds, researchers have identified an exomoon candidate around the transiting exoplanet Kepler-1625b that indicates the presence of a previously unknown gas-giant ... read more

Oct. 2, 2018 — Astronomers have discovered a new extremely distant object far beyond Pluto with an orbit that supports the presence of an even-farther-out, Super-Earth or larger Planet ... read more

Astronomers Use Earth's Natural History as Guide to Spot Vegetation on New Worlds

Sep. 24, 2018 — By looking at Earth's full natural history and evolution, astronomers may have found a template for vegetation fingerprints -- borrowing from epochs of changing flora -- to determine the age of ... read more

Sep. 7, 2018 — The reason Pluto lost its planet status is not valid, according to new ... read more

Sep. 5, 2018 — Using data from NASA's Kepler Space Telescope, an international team has discovered a new exoplanet twice the size of Earth. It orbits its star every six days and is thus very close to it, about ... read more

Aug. 31, 2018 — The conditions for life surviving on planets entirely covered in water are more fluid than previously thought, opening up the possibility that water worlds could be habitable, according to a new ... read more

Stellar 'Swarms' Help Astronomers Understand the Evolution of Stars

Aug. 28, 2018 — Researchers have identified nearly a thousand potential members and 31 confirmed members of stellar associations -- stars of similar ages and compositions that are drifting together through space -- ... read more

Aug. 27, 2018 — Researchers can now show how Jupiter was formed. Data collected from meteorites had indicated that the growth of the giant planet had been delayed for two million years. Now the researchers have ... read more
