The exoplanet, a planet beyond our solar system, has been dubbed TWA 7b after NASA's James Webb Space Telescope captured ...

JWST has made another breakthrough. Around a newly formed star just 111 light-years away, the powerful space telescope has ...

For centuries, planets beyond our solar system—called exoplanets—existed only in theory and science fiction. It seemed nearly impossible to detect planets light-years away, since the ...

Hydrogen and helium atmospheres could keep exoplanets warm enough to be habitable for billions of years, even at huge distances from their stars. Astrobiologists normally think of the habitable ...

Exoplanets—planets that orbit stars beyond our solar system—have transformed our understanding of the universe. Since the first confirmed discovery in the 1990s, more than 5,000 have been ...

Tinetti, whose background is in theoretical physics, developed an interest in exoplanets when she was doing her PhD in Turin, and she ‘converted’ to an exoplanet scientist.

But as a small, dim type of star called a red dwarf, no one has discovered an exoplanet here before -- though there were hints found in 2018 that such a planet might exist.

Since then, nearly 2,000 confirmed exoplanets have been discovered—most by the Kepler Space Telescope—and thousands more candidate planets await confirmation.
