Astronomers heading the search for extraterrestrial intelligence predict their quest might first spark an encounter with ...

K2-33b, depicted in this illustration, is among the youngest exoplanets discovered to date by NASA's Kepler Space Telescope. This artist's rendering depicts a giant exoplanet causing small bodies to ...

Recently we learned about the exoplanet Kepler-186f, a potentially earthlike, potentially habitable world only around 500 ...

In their search for potentially habitable planets outside our solar system, researchers have discovered an extrasolar planet ...

NASA has explored the space beyond Earth and our solar system with spacecraft like Voyagers 1 and 2, and how we’ve discovered ...

TOI 849 b is a stripped-down planet that offers a glimpse into the harsh conditions that could lead to the loss of an atmosphere. Located about 730 light-years away, this exoplanet is made up mainly ...

Kepler-70b, a planet hotter than the Sun at 6,800°C, orbits a dead star, defying cosmic odds. Once a gas giant, it’s now a ...

The alien world is several times the mass of Jupiter and the closest exoplanet to ever be directly imaged. One of Webb's science instruments has a coronagraph to blot out bright starlight ...

When we think of exoplanets that may be able to support life, we home in on the habitable zone. A habitable zone is a region around a star where planets receive enough stellar energy to have ...

The nearby bright star Vega is surrounded by a surprisingly smooth, 100 billion-mile-wide disk of cosmic dust, confirming that it is not surrounded by any exoplanets, JWST images reveal.

One thing we've learned in recent decades is that exoplanets are surprisingly common. So far, we've confirmed nearly 6,000 planets, and we have evidence for thousands more. Most of these planets ...
