Cosmic dust transfers life between planets

Life on our planet may have appeared due to the cosmic dust that travels all over the cosmos, transferring the bricks of life after the objects passing through it. Interplanetary dust penetrates the upper layer of the Earth's atmosphere every day.
Researchers at the University of Edinburgh decided to carry out his analyzes and computer simulations, to check on this basis whether it is thanks to him that life in space is sown.
It turns out that small particles of cosmic dust travel at a speed of about 70 kilometers per second and at an altitude of about 150 kilometers above the Earth's surface can come into contact with biological organisms in the upper layers of the Earth's atmosphere. From there they travel along with the cosmic dust all over the Solar System, and beyond it, penetrating the atmosphere of alien worlds.

Astrobiologists believe that it was in such an obvious way that life could be created on Earth. It also means that on other celestial bodies it could have been created in the same way, but later develop a little differently.
Until then, we have not discovered any, but it may soon change, due to the mission to the saturnites of Jupiter or Saturn, which are promising in this respect.
