Astronomers have identified a quartet of small rocky planets orbiting Barnard's star - one of our closest stellar neighbors - ...

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 ...

Earth" planet named HD 20794 d, located 20 light-years away, which could have conditions suitable for life.

As it orbits its star, it moves close enough at one point to experience extreme heat, similar to Venus’s temperature. But at its farthest point, the planet is nearly twice the distance from Earth to ...

With an orbit of 647 days, HD 20794 d is similar to Mars in our solar system. However, its orbit around the star is highly ...

Astronomers have revealed new evidence that there are not just one but four tiny planets circling around Barnard's Star, the second-nearest star system to Earth.

Wolf 359, a red dwarf star just 7.8 light-years away, could host planets, but extreme X-ray and ultraviolet radiation make ...

At first glance, that seems like a good starting place to hunt for alien life in other systems. After all, there’s only one kind of life known in the universe (ours) and it exists in the Habitable ...

For context, our Sun’s temperature is 5772 Kelvin (9,930 degrees Fahrenheit/5,499 degrees Celsius). Kepler-62 currently hosts five known exoplanets, with two of them orbiting within its star’s ...

This requirement is the basis of the habitable zone, the region around a star where ... high amounts of ultraviolet radiation from the sun catalyze reactions that convert sulfur dioxide to ...

The other subject is Kepler-62, a "main sequence" star at a similar phase in its evolution as our sun. Using a 3D global ... The white dwarf star's habitable zone—the region in which an ...
