Oct. 9, 2024 — Astronomers have observed Jupiter's legendary Great Red Spot (GRS), an anticyclone large enough to swallow Earth, for at least 150 years. But there are always new surprises -- especially when NASA's ...
Sep. 27, 2024 — A crater-rich dwarf planet named Ceres located in the main asteroid belt between the orbits of Mars and Jupiter was long thought to be composed of a ...
Sep. 26, 2024 — A 2020 microlensing event was caused by a planetary system with an Earth-like planet and brown dwarf. The star type was uncertain. The team has ...
Sep. 19, 2024 — By staring into the hellish landscape of Jupiter's moon Io -- the most volcanically active location in the solar system -- astronomers have been able to study a fundamental process in planetary ...
Sep. 3, 2024 — Around 4 billion years ago, an asteroid hit the Jupiter moon Ganymede. Now, a researcher realized that the Solar System's biggest moon's axis has shifted as a result of the impact, which confirmed ...
Aug. 22, 2024 — Researchers studying meteor showers have found that not all comets crumble the same way when they approach the Sun. In a new study, they ascribe the differences to the conditions in the ...
Aug. 1, 2024 — Researchers have developed a new model to explain the formation of giant planets such as Jupiter, which furnishes deeper insights into the processes of planet formation and could expand our ...
July 21, 2024 — Europa and Enceladus, icy moons of Jupiter and Saturn respectively, have evidence of oceans beneath their crusts. A NASA experiment suggests -- if these oceans support life -- signatures of that life ...

Jan. 9, 2024 — Astronomers have found a brown dwarf (an object more massive than Jupiter but smaller than a star) with infrared emission from methane, likely due to energy in its upper atmosphere. This is an ...
Dec. 13, 2023 — Brown dwarfs are objects that straddle the dividing line between stars and planets. They form like stars, growing dense enough to collapse under their own gravity, but they never become dense and hot ...
Dec. 7, 2023 — The extrasolar planets Kepler-1625b and Kepler-1708b are supposedly the home worlds of the first known exomoons. A new study now comes to a different ...
