Exoplanets

In two related firsts, the James Webb Space Telescope has discovered sand-filled rains on a distant exoplanet as its "sandcastle" partner world forms from sandy matter before the eyes of astronomers.

With 10 times the mass of our planet, and spending only part of its orbit in the habitable zone, Kepler-725c is very different to Earth.

A giant exoplanet is surprisingly chill given how close it is to its red dwarf star — perhaps because the star is so little.

A new device uses quantum optics to filter out starlight in real time — bringing scientists closer to directly observing Earth-like worlds.

New research has found that lightning, while not very common, can occur on tidally locked exoplanets like our nearest neighbor, Proxima b.

Plato, the European Space Agency's terrestrial planet hunter spacecraft, is seen after having 24 of its 26 cameras installed.

Luke found life on Tatooine to be boring, but he should be glad, because as we have seen, binary stars have the potential to play all kinds of havoc on their orbiting circumbinary planets.

Astronomers have captured the sharpest, most detailed images yet of young solar systems where planets are just beginning to take shape.

Super-Earths can exist in wider orbits around their parent stars than was previously believed, suggesting these Earth-like exoplanets could be more common than we thought.

Astronomers discovered a planet that orbits its star so closely that its surface is being scorched into magma and vaporizing into space.
