Artist's concept of a potentially habitable super-Earth orbiting a star called HD 20794. Illustration credit: Gabriel Pérez ...

Astronomers have discovered that sulfur may be a key to helping us narrow down our search for life on other planets. It's not that sulfur is a great indication that a planet is inhabited. Instead, ...

The habitable zone for complex life (blue) is highly restricted relative to the zone defined by the potential for liquid water, due to toxic buildup of carbon dioxide (yellow) and carbon monoxide ...

They provide a starting point in how to do that, focusing on what they call the “photosynthetic habitable zone” (PHZ) and identifying five planets in it. A star’s habitable zone is currently ...

Astronomers have identified a super-Earth orbiting a Sun-like star just 20 light-years away, making it one of the closest and ...

The Habitable Zone is a central concept in our explorations for life outside the Earth. Is it time to abandon it? The Habitable Zone is defined as the region around a star where liquid water can exist ...

HD 20794 D is located within the so-called "Goldilocks zone", where temperatures would support the presence of liquid water, a prerequisite for life. "Having a planet in the habitable zone is not ...

Earth, HD 20794 d, in the habitable zone around a Sun-like star 20 light-years away. With a mass six times that of Eart ...

An international team, including the UNIGE, has discovered a super-Earth that will enable astronomers to test new hypotheses in the search for life in the Universe.

Because most planets derive their heat from their host star, that temperature range corresponds to a certain orbital distance known as the habitable zone. Because it is “just right” for life ...

Astronomers have detected a relatively close exoplanet orbiting in the habitable zone of its star, where temperatures are just right to support liquid water on the surface. There's still some ...

A new world has just been found orbiting a Sun-like star only 20 light-years away, and it could be one of the most promising ...
