The idea that life can spread from world to world dates as far back as ancient Greece and the philosopher Anaxagoras.

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 ...

Tiny life forms tucked into debris from an asteroid hit could catapult to other planets—including Earth—and survive, a new ...

Hardy bacteria could survive the trip from one planet to another, hidden among the debris from an asteroid impact, a new study suggests, providing possible evidence for a theory that the seeds of life ...

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 ...

Add Yahoo as a preferred source to see more of our stories on Google. Deep layers of molten rock inside some super-earths could generate powerful magnetic fields—potentially stronger than Earth’s—and ...

Learn how bacteria survived a simulated asteroid impact and could travel between planets on asteroid debris.

Researchers from the University of Greifswald and the Max Planck Institute for Astronomy (MPIA) in Heidelberg (both in Germany) have developed a prototype experimental setup that simulates flow ...

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 ...

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 ...

This photo shows the upper part of the water tornado model. The acrylic glas tank has a diameter of 50 centimetres and is illuminated with LED strips. The water forms a vortex whose surface shape ...
