After two decades of collecting material in Antarctica, a group of scientists is now ready to name the exact amount of cosmic dust falling to Earth — 5,200 tons annually.
There is a site on the moon where signs of life can be found, and in the form in which it first came to Earth.
The distant star Gliese 710 will approach the Solar System in about a million years, and when it does, a swarm of dangerous comets will descend on us.
In January 2016, the news about the discovery of the ninth planet of the Solar System spread around the world. Michael Brown and Konstantin Batygin found signs of its existence in the movement of small bodies on the outskirts of our cosmic home. However, practice shows that decades sometimes pass from the first suspicions to the real discovery. Very often, the search for hypothetical planets ends in a dead end.
During its existence, our planet has encountered sasteroids and comets countless times. During her youth, this often happened and often had disastrous consequences. Later, such collisions occurred immeasurably less often, but the time of time still took place. Suffice it to recall the 10-kilometer celestial alien that fell on Earth 65 million years ago and marked the end of the era of dinosaurs, as well as the cometary nucleus, which on June 30, 1908 exploded over Podkamennaya Tunguska.
