The exoplanet with the “interesting” name LHS 3844b is very similar to the Earth, closely revolves around its star. The only difference is that there is no atmosphere at all.
Our Galaxy has a large number of relatively high density celestial bodies orbiting stars. Theoretically, there should be billions of them, and many of them have the conditions for the development of a complex life.
But besides a solid surface, they must have an atmosphere. Just the twin of the Earth - the planet LHS 3844b - does not have it. Its size is almost a third larger than the earth. An object revolves around a star, much dimmer than our Sun. A planet completes a full revolution in orbit in only 11 days, and this indicates that it is located very close to its sun. Calculations show that, despite the dimness of the mother star, the planet should heat up and light up well. In turn, a relatively high temperature and good lighting conditions should contribute to the emergence of life.
Almost one-hour observations from the space telescope show that the planet, apparently, does not have an air shell at all. This is confirmed by astronomer Laura Kreidberg in his article in the prestigious British scientific journal Nature.
For a long time, the data obtained by the telescope were not combined with any models existing in astronomy. After all, they did not correspond to atmospheres where there is a predominant proportion of carbon dioxide, or nitrogen, as it is on Earth.
Studies show that if there is an atmosphere on the exoplanet under consideration, then it is very rarefied - not denser than the Martian one. The presence of the remains of the air envelope again does not correlate with such a large space object, because the planets do not have an atmosphere, much smaller than the Earth both in mass and in volume.
Meanwhile, telescope data indicate that the planet LHS 3844b is a stone lifeless desert, similar to Mercury. And even if a resident of the Earth wanted to visit this planet, a comparatively dim star shining in the sky like a gigantic ball would be mortally dangerous. Powerful cosmic and radiation radiation, the solar wind and the flow of a large number of charged particles would instantly kill even the embryos of life, leaving behind bare stones.
