This planet orbits a small star, completing each rotation in two days. That quickness means the planet is much too close to its star, making its surface scorching hot.

Tylos, a gas giant, orbits so near its star at such speed that years whiz by in barely 30 Earth hours. The planet is ...

The hellish planet is called GJ 367b, and it’s roughly 30 light-years away from the Earth. The new planet is smaller than Earth — around three-quarters the size to be exact.

GJ 367b is hellish world with a near global lava ocean. How it came to be that way will tell us if planet's like Earth are common, our freakish rarieties.

Only about 41 light-years away from Earth, our planet has a hellish cousin. It's a strange world named 55 Cnc e, otherwise known as Janssen, that tests the boundaries of how close a planet can get ...

Webb Telescope: This hellish planet could be a "Rosetta stone" for finding alien life. JWST will look at Gliese 486 b — too hot to sustain life, but which could bear an atmosphere.

Does this hellish planet harbor a grim climate warning for Earth? There are two primary concepts of how Venus could have evolved over the last 4.6 billion years.

The planet Venus is like Earth’s worst twin – roughly the same size but with a thick layer of acid clouds over a crushing, hellish atmosphere. Its clouds in particular have been a source of interest, ...

The planet, called 55 Cancri e or Janssen, is about 8.8 times more massive than Earth, with a diameter about twice that of our planet. It orbits its star at one-25th the distance between our solar ...

Powerful winds carrying metals in a planet-wide jet stream have been discovered on a hellish world where we already know it rains molten iron. For the first time, scientists have been able to map ...

Once in situ around the hellish planet, DAVINCI will drop a probe through its atmosphere, collecting vital data. Though the probe isn't designed to survive the descent, ...
