Since we cannot look into the interiors of stars and planets, we rely on lab experiments to replicate the physical processes ...

A liquid-gallium experiment has reproduced a turbulent convection regime long predicted to occur inside rapidly rotating ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. The first experiment to produce oxygen on another planet has come to an end. Since starting the experiment, it has generated 122 ...

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 ...

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 ...

Some planets might produce their own water instead of relying on outside sources. In laboratory experiments, researchers simulated extreme conditions found within certain exoplanets by blasting ...

Planets can be extremely hot when they are born, and new computational experiments show that such planets would have an atmosphere composed of a homogenous mixture of hydrogen and water. As the ...

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 ...

Rain is usually made of water, but elsewhere in the Solar System the weather can be unimaginably different. Scientists from SLAC National Accelerator Laboratory believe that on two giant planets, ...
