Scientists have found thousands of planets outside our solar system, called exoplanets, throughout the galaxy. This artist’s ...

Astronomers might be close to confirming the presence of an Earth-like atmosphere on an exoplanet for the first time, ...

A new study challenges the dream of water-rich “Hycean” planets like K2-18b, suggesting that most sub-Neptunes lose their water deep into their interiors during formation. Instead of vast oceans, ...

When most people imagine the vastness of space, they picture a dark void with plenty of observable objects. Planets, stars, and other galaxies often come to mind when picturing what space actually ...

NASA confirms that the number of discovered exoplanets outside our solar system has reached 6,000, marking a major milestone in space research.

Astronomers have used observatories around the world, including the European Southern Observatory's Very Large Telescope (ESO ...

“These microbes, if we found them, would be anaerobic,” Schwieterman explains in the release, meaning the microscopic organisms don’t require oxygen to grow. “They’d be adapted to a very different ...
