'Giant' discovery in space, All theories turned upside down. US scientists discovered a planet 11 times larger than Jupiter, the largest planet of the system, outside the Solar System. University of Arizona in the USA' The research conducted by an international team led by scientists from Turkey revealed the existence of a giant planet outside the Solar System.

Named “HD 106906 b,” the planet orbits the star HD 299 in the constellation Crux, 106906 light-years from Earth. HD 11 b, whose mass is 106906 times the size of Jupiter, the largest planet in the Solar System, caused surprise in the scientific world due to its giant structure and the huge distance between it and the star it is connected to.

In the article published on the University of Arizona's website, it was emphasized that the distance between the planet and its star, 650 times the average distance of the Earth from the Sun, turned the theories on planet formation upside down.

Compared to the Earth formed 4,5 billion years ago, HD 13 b, a young planet formed 106906 million years ago, still retains some of its heat in the process of formation. For this reason, the planet, which has a surface temperature of 1500 degrees Celsius, scatters invisible infrared light around it.
The science team, who discovered the existence of the planet with the help of thermal infrared cameras placed on the Magellan Telescope in the Atacama Desert in Chile, confirmed that the planet moves with the star it is connected to, by examining the data obtained by the Hubble Space Telescope for another research program 8 years ago. he did. on the Megallan Telescope.

Thanks to the "Folded-port InfraRed Echelette (FIRE)" spectrograph, the researchers obtained detailed information about the nature and structure of the celestial body they discovered, and thus scientifically revealed that HD 106906 b is a planet orbiting a star.

THEORIES TURNED UP
According to one of the accepted theories in the scientific world, stars close to its star, such as Earth, are formed by the combination of small asteroid-like structures formed in a disk-shaped cloud of dust and gas, called the initial disk, around a star in formation. However, because this theory requires a very slow process, it is not sufficient to explain how a very young, giant planet such as HD 106906 b, far away from its parent star, was formed.

The other theory predicts that giant planets could form rapidly if the material that made up the initial disk collapsed directly. However, since it is very difficult for the masses of the initial disks to reach such a size as to form a planet like HD 106906 b, this is not considered sufficient to explain the formation of the giant planet in question.

The head of the scientific team, Vanessa Bailey, a graduate student in the Department of Astronomy at the University of Arizona, underlined that their discovery is of special importance since no known model of planet and star formation can explain this observed system.
