An exoplanet discovered in 2020 contains the coldest temperatures ever measured on a planetary body, according to scientists.

At a frigid -125 degrees Fahrenheit (-87 degrees Celsius), WD 1856+534 b is the coldest planet ever directly observed, ...

Astronomers have discovered that "super-Earth" planets may exist on wider orbits than previously thought — and this implies ...
