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 ...

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 ...

First measured the emissivity—the extent to which a surface radiates the energy it encounters—of 15 basaltic samples for ...

Scientists have discovered a nearby exoplanet that is just a baby by planetary standards, located 520 light-years away.

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 ...

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.

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 ...

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 ...
