Liquid water on planets with a primordial atmosphere can be long-lastingMaltagliati, LucaNature Astronomy
According to the Kepler space telescope, about half the stars similar in temperature our Sun could have a rocky planet capable of supporting liquid water on its surface. Our galaxy holds at least an (estimate) 300 million of these potentially habitable worlds, based on even the most ...
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...

Habitable planets refer to planets that have the potential to support life, specifically those that orbit at a distance from their host star that allows for the presence of liquid water on their surface. The presence of liquid water is considered crucial for the development and sustenance of life...
bright the star is. The green area is the habitable zone (HZ), where liquid water can exist on a planet’s surface. The red area is too hot for liquid water on the planetary surface and the blue area is too cold for liquid water on the planetary surface. Credit: Niels Bohr Inst...
The only planet with liquid water on surface The reason Earth is able to contain water in all of it's forms Its distance from the Sun How many different types life have been cataloged on Earth so far 1.5 million of plants, animals, bacteria, fungi, and others ...
atmospheres but also the intensity of the radiation of their respective stars as well as the planets’ internal heat radiating outwards. While on Earth, this geothermal heat plays only a minor role in the conditions on the surface, it can contribute more significantly on pl...
Volcanoes spewing hydrogen could help make an otherwise inhospitable planet habitable, keeping it warm enough for liquid water to remain on the surface, as in this artist’s image. (Image credit: W. Henning, NASA Goddard) Hydrogen-spewing volcanoes could boost the temperatures of seemingly ...
