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 ...

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 ...

In a groundbreaking revelation, scientists have unveiled an explosive new map of an exoplanet that annihilates water. This map provides a detailed view of the planet’s volatile surface and atmospheric ...

In addition to shaping the interior of rocky planets, molten rock located deep within these planets may also contribute to the creation of a planet’s magnetic fields, which protect the entire planet ...

Researchers have discovered more than 6,000 exoplanets in our Milky Way. Of these, the sub-Neptune class, which are smaller than Neptune and more massive than Earth, are the most common. These planets ...

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 ...

SLAC’s X-ray laser and Matter in Extreme Conditions instrument allow researchers to examine the exotic precipitation in real-time as it materializes in the laboratory Earlier experiments that ...

How does fine dust aggregate into building blocks that ultimately form entire planets like our Earth? A research team led by the University of Bern, with the participation of ETH Zurich, the ...

Planets form within protoplanetary disks: vast disks of gas and dust orbiting around very young stars. From the finest dust grains to fully-formed planets, several distinct physical processes occur.

Experiments have revealed that the interaction between a hydrogen-rich atmosphere and a molten planet leads to high levels of water production. Through this process, planets could be enriched with ...
