Previous studies suggested that surface ice could be distributed on close-in terrestrial exoplanets around M-dwarfs if heat redistribution on the planets is very inefficient.
Planetary scientists at the University of Colorado Boulder have discovered how Venus, Earth’s scalding and uninhabitable neighbor, became so dry.
Numerous chemical constraints have been possible for exoplanetary atmospheres thanks to high-resolution spectroscopy (HRS) from ground-based facilities as well as low-resolution spectroscopy (LRS) from space.
The Jupiter-Saturn chaotic excitation (JSCE) scenario proposes that the protoplanetary disk was dynamically excited and depleted beyond ~1-1.5 au in a few Myr, offering a new and plausible explanation for […]
The first clue for finding life on other planets is finding liquid water. The moons of Saturn and Jupiter like Enceladus, Ganymede, Europa, and Callisto are suspected of holding oceans […]
Observations of cooler atmospheres of super-Earths and Neptune sized objects often show flat transmission spectra.
The rover has arrived at an area that may show evidence liquid water flowed on this part of Mars for much longer than previously thought.
The period that liquid water was present on the surface of Mars may have been shorter than previously thought. Channel landforms called gullies, previously thought to be formed exclusively by […]
A paper recently accepted by Icarus presents findings about the Kuiper Belt Object 486958 Arrokoth, shedding new light on the preservation of volatile substances like carbon monoxide (CO) in such […]
Researchers have found water vapour in the disc around a young star exactly where planets may be forming.
