A young star called V1298 Tau is giving astronomers a front-row seat to the birth of the galaxy’s most common planets. Four ...

Astronomers have found thousands of exoplanets around single stars, but few around binary stars—even though both types of stars are equally common. Physicists can now explain the dearth.

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...

A new study presents a compelling new model for the formation of super-Earths and mini-Neptunes -- planets that are 1 to 4 times the size of Earth and among the most common in our galaxy. Using ...

Stars and planets are inextricably linked. They form together and stars shape the fate of planets. Stars create the dusty protoplanetary disks that give birth to planets of all kinds. And when a star ...

Chris Lintott of Zooniverse shows ‘Stargazing Live’ hosts Brian Cox and Julia Zemiro the possible planets found so far by the Exoplanet Explorers project, using gumballs to represent different types ...

For centuries our solar system was the only planetary system known to humans. We had no proof other worlds existed beyond those in our own cosmic backyard, and we imagined that if other planetary ...

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 ...

Astronomers have observed four worlds forming in the V1298 Tau. These worlds are puffy at the moment, and are expected to contract in the future.

PARIS (Reuters) - The first satellite dedicated solely to seeking out new planets beyond our solar system will be launched next month, the European Space Agency (ESA) said on Tuesday. The French ...
