Astronomers have identified the clearest signs yet of an atmosphere around a rocky planet outside our Solar System, marking a major step in understanding extreme worlds. Using NASA’s James Webb Space ...

Researchers using NASA's James Webb Space Telescope have detected the strongest evidence yet for an atmosphere on a rocky ...

Of the seven Earth-sized worlds orbiting the red dwarf star TRAPPIST-1, one planet in particular has attracted the attention ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies these rocky, or "terrestrial," worlds are far more common than was suspected ...

More studies are needed to determine whether TRAPPIST-1e has an atmosphere at all, or the hints of methane are linked to the ...

We might take it for granted that Earth is habitable year-round. Researchers have discovered an Earth-like planet with such an eccentric orbit that it swoops in and out of its habitable zone ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt.

Our Sun is about halfway through its life, which means Earth is as well. After a star exhausts its hydrogen nuclear fuel, its ...

NASA's Parker Solar Probe captured this image showing the nightside surface of Venus. A family of asteroids share the planet's orbit, and two new studies suggest that one day the space rocks could ...

A FIERY hell-world that would instantly roast visitors alive has a vast lava ocean – and may be packed with rare gems. The ...

This illustration shows an exoplanet orbiting around two brown dwarfs –– objects bigger than gas-giant planets but too small to be proper stars. ESO/M. Kornmesser Astronomers have discovered a ...
