A rocky planet less than half the mass of Earth seems to have an atmosphere made almost entirely of sulphur dioxide – this ...

A newly confirmed exoplanet around a nearby sunlike star might be astronomers’ best chance yet to look for life beyond the ...

Preliminary data suggested that TRAPPIST-1b was a gray, barren rock ... offering a glimpse into the diversity of rocky exoplanets. For astronomers, TRAPPIST-1b serves as a stepping stone toward ...

WASP-121b is like nothing in the solar system, raining liquid metal and being puffy like a marshmallow. The origins of these ...

Is Earth really exceptional?  A new book seems to reaffirm that notion.  But given the right conditions, primitive life may be a mere byproduct of biophysics.

But only a handful of the exoplanets discovered so far are terrestrial, rocky types like Earth, and very few are in their stars’ habitable zones. For instance, three of the smallest rocky exopla ...

This illustration shows what the hot rocky exoplanet TRAPPIST-1 b could look like based on this work. TRAPPIST-1 b, the innermost of seven known planets in the TRAPPIST-1 system, orbits its star ...

They comprise almost half of all rocky exoplanets discovered so far and take fewer than 10 Earth-days to orbit their star. It’s these worlds’ closeness to their stars that make them super-hot ...

This graphic shows the transmission spectrum obtained by Webb observations of rocky exoplanet GJ 486 b. The science team’s analysis shows hints of water vapor; however, computer models show that ...

Abstract One of the most characterizable types of rocky exoplanets for the coming decades are magma worlds, those with extensive lava or magma oceans at their surfaces, due to their hot, extended ...

The exoplanet team harnessed two decades of light observations captured by the HARPS and ESPRESSO (Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations) instruments ...

Since the discovery of the first planet outside the solar system in the mid-1990s, the catalog of extrasolar planets, or "exoplanets," has grown to over 5,000 entries. Many of these exoplanets are ...
