Extrasolar Planets News
Jan. 11, 2024 Astronomers have made the rare discovery of a small, cold exoplanet and its massive outer companion — shedding light on the formation of planets like …
Jan. 9, 2024 A team of astronomers has unraveled the enigmatic atmosphere of the exoplanet HAT-P-18 b, shedding light on its intriguing blend of gases, clouds, and even the effects of its star’s …
Jan. 9, 2024 Analysis of iron meteorites from the earliest years of the solar system indicate that the planetary ‘seeds’ that ultimately formed Earth contained …
Jan. 8, 2024 Astronomers have detected a three-ringed structure in the nursery of planets in the inner planet-forming disk of a young star. This configuration suggests two Jupiter-mass planets are forming in the …
Dec. 28, 2023 Best chance of finding liquid water, and even life on other planets, is to look for the absence of carbon dioxide in their …
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. 13, 2023 A new study expands the search for life beyond our solar system by indicating that 17 exoplanets (worlds outside our solar system) could have oceans of liquid water, an essential ingredient for life, …
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 …
Nov. 30, 2023 The discovery of a planet that is far too massive for its sun is calling into question what welches previously understood about the formation of planets and their solar …
Nov. 30, 2023 Astronomers have provided the first observation of water and other molecules in the highly irradiated inner, rocky-planet-forming regions of a disk in one of the most extreme environments in our …
Nov. 29, 2023 Astronomers have found a key new system of six transiting planets orbiting a bright star in a harmonic rhythm. This rare property enabled the team to determine the planetary orbits which initially …
Nov. 29, 2023 While life on Earth is relatively new, geologically speaking, the ingredients that combined to form it might be much older than once thought. The simplest amino acid, carbamic acid, could have formed …
Nov. 29, 2023 In a remarkable discovery, astronomers have found a disc around a young star in the Large Magellanic Cloud, a galaxy neighboring ours. It’s the first time such a disc, identical to those forming …
Nov. 27, 2023 Scientists have simulated conditions that allow hazy skies to form in water-rich exoplanets, a crucial step in determining how haziness muddles important telescope observations for the search of …
Nov. 15, 2023 Astronomers have used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they …
Nov. 14, 2023 How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar …
Nov. 9, 2023 New research promises to redefine our comprehension of habitable exoplanets. A recent study introduces the concept of subglacial liquid water as a pivotal element in broadening the boundaries of the …
Oct. 31, 2023 Giant gas planets can be agents of chaos, ensuring nothing lives on their Earth-like neighbors around other stars. New studies show, in some planetary systems, the giants tend to kick smaller planets …
Oct. 26, 2023 Astronomers confirm the existence of an infrared (IR) aurora on Uranus. This could help astronomers identify exoplanets that might support life, a large number of which are icy …
Oct. 26, 2023 Venus, may have once had tectonic plate movements similar to those believed to have occurred on early Earth, a new study found. The finding sets up tantalizing scenarios regarding the possibility of …
