Using HARPS and HARPS-N spectrographs, astronomers have observed a nearby K-type star designated HD 176986, known to host two ...

The exoplanet is believed to be one of the farthest known from Earth. This artist's map of the Milky Way shows the location of one of the farthest known exoplanets, lying 13,000 light-years away. Most ...

This is an artist's rendering of the YSES-1 system, which has two gas giant planets. See how the James Webb Space Telescope imaged them in infrared below. Webb usually observes exoplanets through ...

Surprised astronomers just discovered a world that blurs the line between planet and stellar remnant, hiding in a system known as a “black widow.” “This was an absolute surprise,” said study co-author ...

One such mystery, described in a recent paper in The Astrophysical Journal Letters, concerns circumbinary exoplanets—or rather, the shortage thereof—in the now 6,000+ exoplanets confirmed to date.

An exoplanet host with several background stars. If left uncorrected, the additional light from the background stars can lead to underestimated exoplanet size measurements. The square grid represents ...
