Kepler-1658b, orbiting with a period of just 3.8 days, was the first exoplanet candidate discovered by the Kepler space telescope in 2009. In 2019, astrophysicist Ashley Chontos used sound waves ...

Scientists working on NASA’s Kepler mission have unveiled the first five exoplanets discovered by the space telescope since it was launched in March 2009. The exoplanets – planets orbiting stars other ...

Kepler's role as the leading exoplanet-hunting space telescope was taken over by the Transiting Exoplanet Survey Satellite (TESS), which was launched on April 18, 2018 and completed its primary ...

Imagine stepping onto a distant exoplanet, where vast alien oceans stretch beyond the horizon. Based on data from missions ...

Are we alone in the universe? While no one can say for sure, space scientists know where to start looking—exoplanets. An exoplanet is a planet beyond the cradle of Earth’s eight-membered solar system.

In the journal Nature Astronomy, astronomers announced that the two exoplanets — Kepler-138 c and Kepler-138 d — could be made up of mostly water. But how did they figure that out, ...

The Kepler Space Telescope was retired in 2018 after a nine-year mission that saw it discover an incredible 2,600 confirmed exoplanets, kicking off the modern era of exoplanet research.

The scientists didn’t directly detect water at exoplanets Kepler-138c and Kepler-138d. Instead, they compared the sizes and masses of the planets to models for comparison.

Kepler-1658b is a so-called hot Jupiter, the nickname given to exoplanets on par with Jupiter’s mass and size but in scorchingly ultra-close orbits about their host stars.
