Mar. 5, 2024 A team of astronomers has shed new light on the fascinating and complex process of planet formation. The research brings together observations of ...
Mar. 1, 2024 Up to a certain point, very luminous stars can have a positive effect on the formation of planets, but from that point on the radiation they emit can cause the material in protoplanetary discs to ...
Feb. 29, 2024 Researchers have found water vapor in the disc around a young star exactly where planets may be forming. Water is a key ingredient for life on Earth, and is also thought to play a significant role in ...
Feb. 22, 2024 Luke Skywalker's childhood might have been slightly less harsh if he'd grown up on a more temperate Tatooine -- like the ones identified in a new study. According to the study's authors, there are ...
Feb. 6, 2024 A carbon monoxide (CO)-runaway gap identified in the atmospheres of Earth-like planets can help expand the search for habitable planets. This gap, ...

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 ...
