Southwest Research Institute has collaborated with Yale University to summarize the scientific community's notable progress ...

The nearby star Vega, featured in the 1997 movie Contact, appears to have a smooth disk devoid of giant planets for reasons we can’t explain ...

Mars' global magnetic field may have hung around for 200 million years longer than scientists had thought, possibly giving life a longer window to take hold on the Red Planet.

In PDS 70, for example, it could be that these terrestrial planets lose some of the water that is readily available to them—relying on asteroids to later replenish it.

Abstract: The climates of terrestrial planets with a small amount of water on their surface, called land planets, are significantly different from the climates of planets having a large amount of ...

Nearest young Earth-sized planet could shed light on how terrestrial worlds evolve. At just 400 million years old, HD 63433 d is a teenaged world circling a Sun-like star.

The researchers propose that if a terrestrial planet has substantially less carbon dioxide in its atmosphere compared to other planets in the same system, it could be a sign of liquid water -- and ...

“They suggest this happened when the formation of the terrestrial planets was more or less complete, apart maybe from the giant impact that formed the moon,” says Chambers, of the Carnegie ...

NASA's James Webb Space Telescope has scored another first, detecting evidence of water in a planet-forming disc circling another star where at least two terrestrial-class proto-planets seem to be ...

The largest terrestrial planet is Earth, and the smallest gas giant is Neptune, which is four times wider and 17 times more massive than Earth. There is nothing in between. “In other star systems ...
