May 7, 2020 NASA's Hubble Space Telescope and the ground-based Gemini Observatory in Hawaii have teamed up with the Juno spacecraft to probe the mightiest storms in the solar system, taking place more than ...
Apr. 29, 2020 A team of astronomers has discovered a planet three times the mass of Jupiter in the Kepler-88 system. The team found that Kepler-88 d is the most massive known planet in this system - not Kepler-88 ...
Mar. 9, 2020 Numerical simulations showed that the temperature gradient in the disk of gas around a young gas giant planet could play a critical role in the development of a satellite system dominated by a single ...
Feb. 20, 2020 Astronomers from the University of Warwick have observed an exoplanet orbiting a star in just over 18 hours, the shortest orbital period ever observed for a planet of its ...
Feb. 18, 2020 A team of scientists using the Low Frequency Array radio telescope in the Netherlands has observed radio waves that carry the distinct signatures of aurorae, caused by the interaction between a ...
Jan. 13, 2020 Scientists have finally scaled the solar system's equivalent of the Rocky Mountain ...
Dec. 23, 2019 Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) found a young star surrounded by an astonishing mass of gas. The star, called 49 Ceti, is 40 million years old and ...
Dec. 11, 2019 The most extensive survey of atmospheric chemical compositions of exoplanets to date has revealed trends that challenge current theories of planet formation and has implications for the search for ...
Oct. 16, 2019 For the first time, astronomers have witnessed 3D motions of gas in a planet-forming disk. At three locations in the disk around a young star called HD 163296, gas is flowing like a waterfall into ...
Oct. 15, 2019 The entry probe of the Galileo mission to Jupiter entered the planet's atmosphere in 1995 in fiery fashion, generating enough heat to cause plasma reactions on its surface. The data relayed ...
Oct. 7, 2019 Move over Jupiter; Saturn is the new moon king. A team has found 20 new moons orbiting Saturn. This brings the ringed planet's total number of moons to 82, surpassing Jupiter, which has ...
Sep. 27, 2019 There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA's WFIRST space telescope, according to new models of ...
Sep. 11, 2019 Researchers have described a new, lower size limit for planets to maintain surface liquid water for long periods of time, extending the so-called Habitable or 'Goldilocks'' Zone for ...
Aug. 29, 2019 A rocky extrasolar moon (exomoon) with bubbling lava may orbit a planet 550 light-years away from us. This is suggested by an international team of researchers on the basis of theoretical predictions ...
Aug. 27, 2019 A new study by astronomers has found that the temperature on the nightsides of different hot Jupiters -- planets that are similar size in to Jupiter, but orbit other stars -- is surprisingly uniform, ...
