Rain drops on distant planets should be similar to earthly, found out scientists

2 min read

The atmosphere of the planets of the solar system and in distant galaxies differ radically from the earth. Liquid methane, hydrochloric acid or something else can drip from the sky or something else, but rain drops in all the worlds will be roughly similar, suggests a new study. This will help predict climatic changes in the atmospheres of the planets of our system and in the atmospheres of exoplanet A, ultimately, can make some clarity in assessing the inhabitancy of other worlds.

The study, the progress of which scientists told in the publication Journal of Geophysical Research: Planets, was held on the basis of Harvard University. Scientists simulated the behavior of rain droplets when passing through the atmosphere of planets and the moons of various sizes, temperature and composition. It turned out that the maximum size of the drops is not very different from the world to the world.

During the imitation of an alien atmosphere, the biggest drops were formed in the Atmosphere of Titan (Saturn Satellite). In Titan in the form of rain from the sky, liquid methane is pouring and going to methane rivers, lakes and seas. Rain drops on titanium reached three centimeters wide, which is about three times more than the maximum rain drops on the ground (1.1 cm).

«Rain drops of different compositions can have a rather small range of stable sizes; All of them are fundamentally limited to about the same maximum size, “said the lead author of the graduate student of the Department of Sciences on Earth and Planets Katelin Loftus (Kaitlyn Loftus). For stony planets, rain drops to fly to the surface of the planets should have a radius from 0.1 mm to a few millimeters, regardless of which they are formed, researchers explain.

«The knowledge that we get, reflecting on rain drops and clouds in various environments, is the key to understanding the inhabitants of exoplanets, – declare scientists. – In the long run, they can also help us understand the climate of the earth itself. “
