Snow
Snow is composed of ice crystals.
Each crystal is transparent, like ice. Light is reflected and scattered at the interface between the ...
Titan
Most of the dunes are located near the equator.
They stretch for hundreds of kilometers, and their height reaches 100 meters. Unlike Earth’s, Titan’s dunes are made of organic compounds.
Deimos
Deimos was discovered by American astronomer Asaph Hall on August 12, 1877, through a telescope at the US Naval Observatory.
It was not discovered accidentally, the astronomer conducted observations precisely to find the planet's natural satellites.
Moon
The average time between new moons is 29 days, 12 hours, 44 minutes and 3 seconds. We call this period the synodic month.
It is longer than the sidereal month because in the process of illuminating the moon's disk, we must take into account the movement of the Moon itself, as well as the Earth and the Sun.

As much as 75 percent of the atmosphere is at an altitude of less than 11 kilometers. With each addi ...

The rate of relapse after treatment ranges from 9 to 52 percent, with many studies reporting a relapse rate of at least 25 percent.
Relapse occurs in about one-third of people in the hospital and is greatest in the first six to 18 months after discharge from the facility.
Phobos
Phobos is believed to be an asteroid that has been intercepted by the gravitational field of Mars.
Both Phobos and Deimos share many similarities with C- or D-type asteroids.
Brain
Physical activity is equally important for the proper functioning of the brain, as it helps to create new nerve connections.
Medium-intensity aerobic exercise is considered the most effective.
Phobos
There is a ridge on the surface of the moon, called the Kepler Dorsum.
It was named after the German astronomer, Johannes Kepler.
Enceladus
Underneath the icy crust is an ocean of liquid water 75 kilometers deep.
