First Confirmed Planet in a White Dwarf's "Forbidden Zone"

A giant gas planet with mass equivalent to about 13.8 times Jupiter was announced in 2020. Orbing a star at 81 years of light from the Earth, which is relatively close in astronomical terms, is the first planet known for orbiting a white year. Called WD 1856+534 b, it was detected in transit, i.e., passing before its star from our point of view, which allows its indirect observation. The discovery surprised because, when a star dies, it collapse…

First Confirmed Planet in a White Dwarf's "Forbidden Zone"

In our Solar System, there is no sub-Neptune. A type of exoplanet yet widespread in our Milky Way. Thanks to the James-Webb space telescope, astronomers begin to pierce their secrets.
