It is not the ordinary levels of hot!
It is said that summer heat will get hotter this summer. It was revealed that a planet "KELT-9b" temperature rises to 4,300 degrees Celsius is found at 650 light-years away from the earth.
KELT (Kilodegree Extremely Little Telescope), an international research team centered on astronomers at Ohio State University, discovered in 2014 that small depressions were seen in the star "KELT-9". Which proceeded to observe from the prediction that this hollow may be the shadow of a planet traversing in front of KELT-9, and have identified the existence of KELT-9b of a giant gas planet.
K E L T - 9 vs K E L T - 9b
The size of the star KELT-9 of KELT-9b is 2.85 times the sun and it is shining at a high temperature of 10,000 degrees Celsius. And KELT-9b is in a position where it revolves with a short cycle of 1.48 days, which is very close to the high - temperature KELT-9, and it always rotates on the same side facing the KELT-9, It is thought that the daytime temperature is over 4,300 degrees. KELT-9b is a clear planet, but it gets higher than some stars. It is too hot, so it is thought that water, carbon dioxide, and methane molecules are not formed.
According to Scott Gaudi of Ohio State University who has been engaged in this research at KELT.
Astronomy, in a sense, is also a study of the extreme world. Many of the phenomena encountered in astronomy are far beyond the events experienced in everyday life and therefore it is necessary to extend the law and understanding of physics to the limit. However, understanding of the universe will deepen as it tries to overlap such limitations research and understanding. Nature is far beyond human imagination and has a number of mysteries.
Generally, in search of the existence of extraterrestrial life forms, research observation of extrasolar planets has been promoted so far, but the possibility of an existence of this life is almost unlimitedly close to zero in the study of KELT-9b It is emphasized that there is great significance, too.
It is also thought that too strong ultraviolet rays from KELT-9 which radiates radiance at high temperature let out the atmosphere of KELT-9b and shine like the comet's tail. And if the outflow of the atmosphere continues with this momentum, there is a high possibility that it can not exist as an independent planet with a short span of several million years. The observation of KELT-9b, which no one had ever seen, will be continued in future Spitzer Space Telescope, Hubble Space Telescope, James Webb Space Telescope and so on. It may be unexpected that so many discovery will come out too soon.
