In the coming days, the James Webb Space Telescope will determine the mass of the newborn planet and study the chemical composition of its atmosphere.
Astronomers have discovered more than 5,000 exoplanets in the past 30 years. The last of these became the youngest planet discovered in our galaxy. The New York Times reported it.
Experts suggest that the star AS 209 is located 395 light-years from Earth in the constellation Ophiuchus, and is so young that it still has a protoplanetary disk around it. This disk is a collection of gas and dust from which the planets formed.
It is noted that this planet is similar in mass to Jupiter, but very far from its star. For example, Neptune, the most distant planet in our solar system, is located at a distance of about 4.5 billion km from the Sun. This exoplanet is located at a distance of about 30 billion km from its star.
“Discovering this planet and observing it is like observing Earth’s past. After all, our planet also formed from a protoplanetary disk. In the near future, the Webb Space Telescope will determine the exact mass of this planet, its size and study the chemical composition of its atmosphere,” said Miriam Benisti of the Institute of Planetary Science and Astrophysics in Grenoble.
It was previously reported that scientists, after gaining access to a supercomputer system, published an image of the supernova remnant G261.9 + 5.5.
