Using the James Webb Space Telescope, astronomers have discovered an example of a new class of exoplanet, and it smells like ...

The planet's environment would make it unlikely to sustain life.

An exoplanet is a planet outside our Solar System. As of March 2020, we’ve discovered over 4000 different ones. So, it sounds like we have some options for our interplanetary house hunt, but we do ...

Astronomers have found an exoplanet that could serve as a benchmark in future studies. It's a rocky planet orbiting an M-type star, and though these planets are plentiful, this one could serve as a ...

The molten planet, with an atmosphere rich in sulfur-bearing gases, is unlike anything astronomers have ever smelled.

Up until now, exoplanet surveys have mostly focused on nearby, bright stars that are sun-like or are red dwarfs, which are known to frequently host planets. While astronomers have discovered thousands ...

Astronomers have discovered a bizarre exoplanet with a giant underground ocean of magma that traps sulphur and may represent an entirely new class of worlds.
