Astronomers broke major ground in their hunt for new worlds after potentially locating a giant, habitable planet near the ...

Artist impression of one type of Delta Scuti pulsation, that is driven by waves (blue arrows) traveling between the star's ...

This summer, exoplanet science—the study of planets orbiting stars beyond our sun—took a big step forward. Reports of helium ...

Add Yahoo as a preferred source to see more of our stories on Google. Some exoplanets, like the one shown in this illustration, may have atmospheres that could make them potentially suitable for life.

The old adage that it's easier to prove a negative could play a crucial role in characterizing nearby exoplanets that could harbor life. The idea is that looking for earth-like planets is tough enough ...

The most recent planet discoveries bring the number of known exoplanets–planets outside our solar system–to 236, the researchers told a meeting of the American Astronomical Society in Honolulu on ...

Planets appear to be common around stars in our home galaxy, the Milky Way. Astronomers have found planets not just for stars like our sun, but also for smaller, cooler red dwarfs and other types of ...

A nearby star system with two suns could potentially support an Earth-sized planet in a region where liquid water could exist ...

Could violent stellar flares make planets more habitable? Small, low-mass stars such as red dwarfs are well-known for blasting out powerful flares. And when they do, they send waves of radiation ...

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 ...

When astronomers search for planets that could host liquid water on their surface, they start by looking at a star's habitable zone. Water is a key ingredient for life, and on a planet too close to ...
