For the first time ... the discovery of a life-like planet Earth

Researchers from the American space and aviation agency "NASA" announced the discovery of a viable planet that revolves around a red dwarf moving away from Earth a hundred light-years away. Scientists have discovered dozens of planets that are viable before, but this is the first time that the discovery is similar to Earth.

Life scale
It is said that the planet is in the valid range of life if it is at a distance from its own star so that the water is on its surface in its liquid form, not close to the star and the water evaporates or far away and freezes, because water is the main ingredient for the possibility of any of the life forms that we know on a planet What.

According to the findings of the research team, which was announced within the activities of Conference No. 235 of the American Astronomical Society, the planet TOI 700 d revolves around a small red star about the size of about half of the sun, and red dwarfs are a group of relatively cold stars, but they are the longest-lived in the entire universe.

The newly discovered planet revolves around its star once every 37 days, and its companions in the same solar system revolve around this star in lesser periods of up to 10 days only.

Search for a planet
To reach these results, the team used the TESS space telescope, which mainly aims to search for Earth-like planets orbiting stars other than the sun, and the results of this research team were confirmed by additional observations from NASA's Spitzer.

In order for space telescopes such as "Tess" to discover the rotation of a planet around another star, it does not visualize those planets, but rather calculates the amount of light from distant stars. To understand the idea, hold a grain of peas or grapes, for example, and pass it between your eyes and the lamp in the ceiling of the room.

The moment the pill passes, the amount of illumination from the lamp decreases. The same thing happens when a planet passes in front of a star, so this star’s lighting decreases for a while and then rises, and the matter is repeated every specified period of time, here scientists know that a planet has passed in front of the star.

Promising tasks
Tess has been operating in an area more than four hundred times the size that the Kepler telescope has sent to search for planets during 2009, opening the door to large near-field discoveries of planets orbiting stars other than the sun.

The relatively recent space telescope also managed, for the first time, to detect a planet orbiting a binary star system, a system in which two stars revolve around one another, and the results were announced at the same conference.

Tess researchers hope that these results will help open up a wider range in the study of other solar systems in the universe, and perhaps one day we may discover the existence of life on one of them, or not.
