The origin of super-Earths and sub-Neptunes has been revealed in a system of four young planets that are dramatically losing ...

A new machine learning model has predicted that there are 44 Earth-like planets in other star systems in the Milky Way galaxy, with researchers from Switzerland claiming that the algorithm at the core ...

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 ...

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 ...

For many years, astronomers have been looking for extraterrestrial life. In doing so, astronomers have narrowed their search ...

Beyond our solar system, sub-Neptunes — gassy planets larger than Earth but smaller than Neptune — reign as the most common type of exoplanet observed in our galaxy. Despite their prevalence, no such ...

A combination of cosmic processes shapes the formation of one of the most common types of planets outside of our solar system, according to a new study. A combination of cosmic processes shapes the ...

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 ...

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