Look at the bare core of a giant planet: scientists have found this for the first time

European researchers have found the massive exoplanet TOI 849 b, it is so close to its star that it has long lost its outer shell. Instead, scientists saw a very dense core, according to Nature.

Scientists have never seen what the core of a planet looks like, so planetary scientist David Armstrong of the University of Warwick in the UK and his colleagues launched a program to detect planetary nuclei using the TESS space telescope. The device monitored the light of many stars and recorded every flicker, which may be associated with the movement of the planet between the star and the Earth.

In the course of observations, they discovered a rocky space object, 39 times more massive than the Earth, which is 730 light-years from us. The exoplanet TOI 849 b rotates in an extremely short orbit, making a full annual revolution around its star in just 18 hours. Temperature object is estimated at about 1800 K.

The planet is located in the “Neptunian desert”, where all objects are exposed to powerful fluxes of radiation: therefore, all gas shells with TOI 849 b were blown away and only a solid core remained.

According to the researchers, this is the core of the largest rocky planet ever discovered. This is the first of the ever discovered cores of gas giant planets such as Jupiter.
