Scientists discover surface conditions of distant exoplanets through NASA Spitzer telescope – Definition Science – cnBeta.COM



According to foreign media reports, a new research paper recently published in Nature suggests that researchers used data from NASA's Spitzer Space Telescope to discover a rare view of the surface of a special exoplanet. It is reported that this planet named LHS 3844b is less than 50 light-years away from Earth, and its volume is slightly larger than that of Earth. However, its surface is far less lively than the Earth's surface.

The planet, originally discovered by NASA's TESS satellite in 2018, is about 1.3 times the size of Earth and only 48.6 light-years from Earth – a distance that allows the Spitzer telescope to detect it through reflected light on the surface of the planet.

Researchers believe that since the planet is very close to the main star, it is locked by the wave, ie one side of the planet always faces the wave. The side facing the star is very hot, the temperature is over 1400 degrees Fahrenheit, and the other side is much colder.

According to Spitzer's observations, scientists who study Spitzer know that the planet is made of rock like Earth, but they think its surface is more like the Moon or Mercury – because the temperature on both sides of the planet There are very big differences, so researchers believe that the planet has no atmosphere, and if it does, the heat will be distributed to the planet in uniform.
