Even JWST can’t separate these tiny planets from their host stars – as they orbit their stars too closely. But there is a way ...

Scientists are trying to figure out how minerals connected to exoplanetary water would look to the James Webb Space Telescope ...

Astronomers using the James Webb Space Telescope have detected possible signs of gases released by volcanic activity on a ...

We could even determine whether certain minerals are present or absent on the surface of an exoplanet, without ever viewing its surface directly. This kind of information is vital to our ...

Data from the massive telescope also suggests the exoplanet, the name for a planet outside the solar system, may also have a surface covered in water and an atmosphere rich with hydrogen.

So, find those minerals, and you may be getting close to the water that formed them — whether that water lies on an exoplanet's surface or is hidden underground. Of course, this concept assumes ...

On Earth, with a lower average surface temperature ... Based on computer simulations, K2-141 b, an Earth-sized exoplanet in a low orbit around an orange dwarf in the Aquarius constellation ...

The rate of exoplanet discovery has since climbed rapidly ... Additionally, researchers can calculate a planet’s surface temperature from the world’s orbital period and its star’s temperature.

Scientists have discovered two “super-Earth” exoplanets, one of which is in its star’s habitable zone. That means liquid water could exist on its surface. The planet, known as LP 890-9c or ...

It's a narrower region around a star where an exoplanet could have surface water. It's defined by an inner runaway greenhouse edge where stellar flux would vaporize surface water and an outer ...

By examining small spectral differences between the basalt samples, scientists can in theory determine whether an exoplanet once had running surface water or water in its interior, said Gazel.
