The cosmos is a void dotted with stars and an ever-increasing number of newly-observed planets beyond our solar system. Yet, how these stars and planets formed out of clouds of interstellar dust and ...

Of the more than 6,000 known exoplanets in the Milky Way, so-called Sub-Neptunes are the most common. They are smaller than Neptune and more massive than Earth and believed to have rocky interiors ...

Planets are formed when dust and rock in a disk around a young star collide and combine to form ever larger bodies. This so-called accretion is not yet fully understood. Astrophysicists at the ...

Our galaxy's most abundant type of planet could be rich in liquid water due to formative interactions between magma oceans and primitive atmospheres during their early years, according to new research ...

(CNN) — The first experiment to produce oxygen on another planet has come to an end on Mars after exceeding NASA’s initial goals and demonstrating capabilities that could help future astronauts ...

An artist’s depiction of an exoplanet larger than Earth and smaller than Neptune. A blue planet in the foreground blocks the light of a star. Recent high-temperature, high-pressure experiments suggest ...

On April 20, 2021, the spiritedly-named MOXIE experiment on Mars extracted 5 grams of oxygen from the Martian atmosphere, demonstrating a potential future capability of an established human presence ...

Planets go through different life stages: They form, evolve and eventually meet an end. But the timelines for these processes differ widely between Earth-like planets and worlds that orbit ...

New research uses laboratory experiments to demonstrate that water is naturally created during the planet formation process. By squeezing and heating planetary analog materials between the tips of two ...
