Second Earth Discovered by Scientists: Will It Be Revealed In NASA Research This Time? The search for a planet close to atmospheric conditions on earth has been ongoing for many years throughout the world. This time, however, it is possible that the discovery of NASA scientists will change the future of humanity. Where is this planet located? Is the newly discovered planet favorable to the development of life? You can read more about the latest discovery of the second Earth in the article below.
Second Earth: What do scientists know?
NASA scientists have been observing space with the TESS telescope since July last year. This type of telescope is designed to search for so-called exoplanets, or lifetimes. The cost of searching for planets similar to our Earth in a planetary system is $ 340 million. and will last until 2022.
The latest discovery by NASA scientists is a planet tracked by the TESS space telescope. The conventional name for a celestial body is GJ 357d. It turns out that the planet has very good conditions for the presence of liquid water. Second Earth is 31 light years away from our Earth.
GJ 357d lies in the constellation of Hydra. It revolves around a red M-type dwarf, e.g. a star about three times smaller than the Sun. Almost as much energy as Mars receives from the Sun reaches its surface.
The "New Earth" is two or three times larger than our planet, and its mass can be up to six times larger. As a result, it may have a thick atmosphere, thanks to which it is warmer, thanks to which liquid water can be on its surface.
What is the light year?
When traveling to a new, second Earth, it should be reckoned that no human could fly there in their lifetime. All because light year means the distance light travels in 12 months. To calculate the distance of the celestial body GJ 357d from Earth, traveling this distance would be 304 trillion kilometers. It would take many astronomers many millions of years to travel this path. Currently, this type of travel can only be observed in film productions.
