Astronomers around the world have confirmed over 6,000 exoplanets, a milestone reached in September 2025. Billions more are ...

With the discovery of ever more exoplanets—over 6,000 now—scientists, of course, want to know if they are habitable for life. (At least, life as we know it.) But assessing habitability is a difficult ...

Data from the James Webb Space Telescope on exoplanet K2-18b has revealed the "strongest hints yet of biological activity ...

“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 ...

Any planet that it images will still look like a point of light, but the spectrum of that point of light could reveal whether the planet has oceans, continents, vegetation, animal life or even cities.

This brings us to the complexity of NASA's announcement. "Confirmed planets are added to the count on a rolling basis by ...

The exoplanet LHS 3844b (left) is 1.3 times the mass of Earth and orbits the star LHS 3844 (right). Discovered in 2018 by NASA’s Transiting Exoplanet Satellite Survey, LHS 3844b is located 48.6 ...

Scientists have found thousands of planets outside our solar system, called exoplanets, throughout the galaxy. This artist’s concept shows how they range in size and composition, although scientists ...

NASA has confirmed 6,000 exoplanets, marking a major milestone in humanity’s quest to understand other worlds. From gas giants hugging their stars to planets covered in lava or clouds of gemstones, ...

It's hard to remember now, but there was a long period of time in which scientists weren't sure how many planets might actually exist throughout the galaxy, much less how likely it might be to find a ...

Discovered: Super-Earth exoplanet seems habitable; it's alive—this gelatinous lab-bred blob; rethinking the theory that genes cause disease; fairy-wrens identify themselves with code words. Do genes ...
