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 ...

Scientists got a never-before-seen look at an area around a large exoplanet 625 light-years away where moons could potentially form.

How will NASA's upcoming Habitable Worlds Observatory (HWO) mission differentiate Earth-sized exoplanets from other exoplanets, specifically Earth-sized exoplanets within the habitable zone, also ...

The striking thing about this is that repeating the procedure on the star turned up no evidence of carbon-based chemicals, even though the system is young enough that it should still have a ...

What kinds of planet does a solar system cook up? It depends on the ingredients you throw in. Astronomers report that the planets that arise around a star can have a vast array of structures that ...

It wasn’t until the ‘90s that our astronomical powers advanced enough to confirm the existence of worlds around other stars. Since that very first discovery, more than 6,000 exoplanets have been ...

An exoplanet has been discovered orbiting Barnard's star by the European Southern Observatory’s Very Large Telescope. Barnard's stars is the closest single star to Earth. Credit: ESO ...

Scientists have gotten a never-before-seen look at an area around a large exoplanet 625 light-years away where moons like the one orbiting Earth could potentially form. Using data from NASA’s James ...

Astronomers using the James Webb Space Telescope are unraveling the mysteries of TRAPPIST-1e, an Earth-sized exoplanet 40 light years away that could harbor liquid water. Early data suggests hints of ...

A new study rules out the existence of global oceans of water on Neptune-like planets such as K2-18b, finding their water usually sinks.

This brings us to the complexity of NASA's announcement. "Confirmed planets are added to the count on a rolling basis by scientists from around the world, so no single planet is considered the 6,000th ...
