It was not until the 1990s that exoplanets were recognized for the first time. Since 2002, more than 20 exoplanets have been discovered each year. Professor Scott gaudy, an astronomer at Ohio State University, said that many of these exoplanets are “wandering planets” and the universe may be full of “wandering planets”, so we need to conduct a comprehensive screening. As a result, NASA is planning a new mission to calculate the number of grams of “wandering planets” in the galaxy, which will use gravity microlens technology to find “wandering planets”. Stray planets refer to planets that do not orbit any star. Although they do not revolve around any star, they only have planetary mass. They are either ejected from the original planetary system due to the gravitational influence of other planets and other celestial bodies, or ejected from the protoplanets during the formation of the planetary system, thus wandering in the galaxy or the universe. Although they roam in the interstellar space, it does not mean that they have no life, but the life on them may be just bacteria like microorganisms. The mission will be based on the Nancy grace Roman space telescope, which will be launched in the next five years, Professor Gaudi said. Based on its advanced nature, scientists will be able to observe the universe in hitherto unknown ways. Professor Gaudi said that the sensitivity of the Nancy grace Roman space telescope to detect these “wandering planets” will be 10 times as sensitive as the current earth based telescopes, and the study predicts that the number of these planets will exceed the number of stars (100 billion) in the galaxy. This will not only help to explain how these “wandering planets” formed, but also bring new clues to the evolution of galaxies.
