Astronomers observed the 'birth' of an exoplanet

Astronomers observed a planet in the process of “birth” in a huge disk of dense gas and dust around a newly formed star, Reuters reported.
The great young planet is formed around the star AB Aurigae (AB Kolar), whose mass is about 2.4 times the size of the Sun. It's in the Milky Way galaxy 520 light-years from Earth. The planet is 30 times further away from its star than the Earth is from the sun. It's possible that it's not rocky, but it's gas and it's bigger than Jupiter, BTA transmits.

Astronomers worked with the Very Large Telescope (VLT) of the European Southern Observatory in Chile. They observed a spiral structure in a rotating disc around the star AB Aurigae, generated by the presence of a planet. They registered changes in the pattern of the spiral structure where the planet formed.

"To finally shape a planet, it takes several million years. So birth is not well defined in time,” explained the study's head Antoni Bocaletti.

More than 4000 exoplanets are known.
