The space
Outer space is the area located XNUMX kilometers above the planet, and this area is distinguished as a vacuum that does not carry any noticeable amount of air for breathing or for the spread of light in it, in addition to being empty with air, so sound does not transmit in it because the molecules are not close enough to transmit sound among them.
It is worth noting that space is made up of gas, dust, and other matter that floats around the empty regions of the universe, while the crowded regions of space contain planets, stars, and galaxies.
energy and space
There is great energy in space, although the vast empty spaces between planets, stars and moons are cold and dark, but space contains electromagnetic energy, and all stars in the universe produce energy and send it to space, and that energy is reflected by planets, asteroids and moons, which makes them illuminate in Dark, and these objects can release energy in the form of heat from volcanoes and other processes, in addition to having kinetic energy in space.
space weather
The activity that occurs on the surface of the sun causes a kind of weather called space weather. Although the sun is very far away, about 150 kilometers from Earth, space weather affects the Earth and the rest of the solar system. In the worst cases, this weather may cause Power outages and damage to Earth's satellites.

Small black holes are formed from the gravitational collapse of giant stars, which constitutes a singularity that nothing can escape from, even light, and it is never known what is inside black holes, but research is still continuing on that.
Stars, planets, asteroids and comets
Stars are massive balls of gas that produce their own radiation, and range from massive red giants to dormant white dwarfs, while planets are celestial bodies orbiting the sun that are massive enough to be round in shape.
Asteroids are known as rocks that are not large enough to be called dwarf planets, and some of these asteroids have rings revolving around them, and it is concluded from their small size that they are the remains of bodies since the formation of the solar system, while comets are defined as bodies originating from a large group of icy bodies called the “Oort cloud.” (English: Oort Cloud).
