A new theory for how rocky planets form could explain the origin of so-called "super-Earths"—a class of Earth-like exoplanets.

For the first time, astronomers have spotted an exoplanet whose orbit is decaying around an evolved, or older, host star.

An Earth-like planet orbiting an M dwarf star discovery could cause a major shift in the search for life on other planets.

When Mars was a young planet, it was bombarded by ice asteroids delivering water and organic molecules necessary for life to emerge.

An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all.

Provides insight into the formation and evolution of asteroids, icy moons and Earth-like rocky planets in the early history of the universe.

An Earth-like planet orbiting an M dwarf — the most common type of star in the universe — appears to have no atmosphere at all.

These types of gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element.

Water is essential for life on Earth and other planets, and scientists have found ample evidence of water in Mars’ early history.

A new study suggests that many more planets may have large amounts of water than previously thought—as much as half water and half rock.

Swirling around the planet’s equator, the rings of Saturn are a dead giveaway that the planet is spinning at a tilt.

Researchers at SLAC found that oxygen boosts this exotic precipitation, revealing a new path to make nanodiamonds here on Earth.

A new citizen science project allows volunteers to play an important role in helping scientists learn more about the atmosphere on Jupiter.

The exoplanet is orbiting one of two small stars in a binary system located in the Draco constellation about 100 light-years from Earth.

The accepted view of Mars is red rocks and craters as far as the eye can see. That’s what scientists expected when they landed Perseverance.

In the last 25 years, astronomers have found thousands of exoplanets around stars in our galaxy, but more than 99% of them orbit small stars

The lava caves, lava tubes and geothermal vents on the big island of Hawaiʻi have higher bacterial diversity than scientists expected

To understand the reason Jupiter currently looks the way it does, Kane and his graduate student Zhexing Li ran a dynamic computer simulation

Liquid water is an important prerequisite for life to develop on a planet. It could also exist for billions of years on planets.

MIT astronomers have discovered two terrestrial, Earth-sized, planets that lie just 10 parsecs, or about 33 light-years, from Earth.
