Liquid water on planets with a primordial atmosphere can be long-lastingMaltagliati, LucaNature Astronomy
Maintaining liquid water on the planet’s surface for long periods, as might be required for the evolution of life, can be impossible beyond the HZ, and even within it if there’s no atmosphere with a sufficient greenhouse effect such as in the case of Mars. Producing liquid water by subg...
Universe Today readers are familiar with the idea of a habitable zone. It basically means liquid water. All other considerations aside, we know that all life on Earth needs liquid water, so we search for other worlds that have it. If a planet, or a moon, hasliquid water, we say it's...
The first planet with a mass comparable to Earth and an orbit consistent with liquid water was reported in 2014 [388], and about twenty so-called habitable planets are now known [389]. The inventory of exoplanets is thus enormous, with thousands of detections already reported [390]. More...
Low-mass planets with a primordial atmosphere of hydrogen and helium might have the temperatures and pressures that allow water in the liquid phase. The presence of liquid water is favorable for life, so that these planets potentially harbor exotic habitats for billions of ye...
Most discussion of habitable planets has focused on Earth-like planets with globally abundant liquid water. For an "aqua planet" like Earth, the surface freezes if far from its sun, and the water vapor greenhouse effect runs away if too close. Here we show that "land planets" (desert world...
Any such planet situated in the right orbit stands a good chance of having liquid water on its surface, and quite possibly life, although a leading scientist involved in the project said it was unlikely to find "any little green men". 4. Developed by the French space agency, CNES, and...
the "Snow Maiden Zone" The paper examines two habitable zones with different physical conditions on exoplanets: planets with liquid water on the surface and conditions close to E... MV Ragul'Skaya - 《Solar System Research》 被引量: 0发表: 2024年 加载更多...
To look for possible ocean worlds, Quick's team selected 53 exoplanets with sizes most similar to Earth, though they could have up to eight times more mass. Scientists assume planets of this size are more solid than gaseous and, thus, more likely to support liquid water on or below their...
