July 13, 2023 Brown dwarf stars rarely emit radio waves. Here scientists have found the coldest star yet emitting at these long wave lengths. Understanding the science of 'ultracool brown dwarfs' will ...
July 12, 2023 A new radar technique developed by a graduate student allows imaging of the upper few feet of ice sheets on Earth and icy worlds. The technique uses instruments on airplanes or satellites to survey ...
June 28, 2023 The star would have inflated up to 1.5 times the planet's orbital distance -- engulfing the planet in the process -- before shrinking to its current size at only one-tenth of that ...
June 17, 2023 Europa may have a metamorphic origin for the ocean. While some scientists speculated this, a research team shows that if Europa indeed formed from hydrated rocks (i.e., rocks have hydrogen and ...
June 8, 2023 Astronomers challenge longstanding beliefs about the isolation of 'hot Jupiters' and proposes a new mechanism for understanding the exoplanets' ...
May 15, 2023 Astronomers have described the first radiation belt observed outside our solar system, using a coordinated array of 39 radio dishes from Hawaii to Germany to obtain high-resolution images. The images ...
Apr. 14, 2023 An international team of astronomers announced the first exoplanet discovered through a combined approach of direct imaging and precision measurements of a star's motion on the sky. This new ...
Mar. 7, 2023 A terrestrial planet hovering between Mars and Jupiter would be able to push Earth out of the solar system and wipe out life on this planet, according to a recent ...
Feb. 22, 2023 Astronomers have discovered an unusual planetary system in which a large gas giant planet orbits a small red dwarf star called TOI-5205. Their findings challenge long-held ideas about planet ...
Feb. 20, 2023 An international team has found two new crystal structures for salty ice, or solid hydrate made from water and sodium chloride. The newly discovered material's properties match those of the ...
Jan. 11, 2023 NASA's James Webb Space Telescope has imaged the inner workings of a dusty disk surrounding a nearby red dwarf star. These observations represent the first time the previously known disk has ...
Jan. 10, 2023 In June 2021, NASA's Juno spacecraft flew close to Ganymede, Jupiter's largest moon, observing evidence of magnetic reconnection. A team has used Juno data to examine the electron and ion ...
Dec. 19, 2022 The condemned planet could help answer questions about the fate of other worlds as their solar systems ...
Dec. 13, 2022 VLA teams up with Juno spacecraft to study Jupiter's atmosphere, and ALMA reveals new details about Io's ...
Oct. 12, 2022 Researchers have now found evidence that double ionised sulphur dioxide contribute to the formation of oxygen molecules. This could, in particular, explain the presence of oxygen in sulphur ...
Sep. 30, 2022 Europa is more than just one of Jupiter's many moons -- it's also one of most promising places in the solar system to look for extraterrestrial life. Under 10 kilometers of ice is a liquid ...
Sep. 21, 2022 NASA's James Webb Space Telescope shows off its capabilities closer to home with its first image of Neptune. Not only has Webb captured the clearest view of this distant planet's rings in ...
Sep. 9, 2022 Of all known planets, Earth is as friendly to life as any planet could possibly be -- or is it? If Jupiter's orbit changes, a new study shows Earth could be more hospitable than it is ...
Sep. 8, 2022 A new study suggests that many more planets may have large amounts of water than previously thought--as much as half water and half rock. The catch? All that water is probably embedded in the rock, ...
Sep. 6, 2022 Jupiter-sized planets can be stolen or captured by massive stars in the densely populated stellar nurseries where most stars are born, a new study has ...
