Space and the galaxies, planets and stars in it are among the areas of concern to many; Therefore, in the following lines, we review information about space, with an explanation of the strangest and newest things that are going on in it.
Space information
Before mentioning information about space and what revolves around it, space can be defined as the space between celestial bodies, and it is called the term outer space because it is distinguished from the air space that surrounds EarthAlso, it is not possible to accurately determine the area of outer space, as a result of the difficulty faced by specialized detectors, as long distances in space are measured in light years, which means the distance traveled by light during one year, and accordingly, the area of space is about 9.3 trillion km, according to what It was reported by Sputnik.
There is also a lot of information about space that can be mentioned, but the most prominent of them are:
The history of space exploration dates back to 1921, which witnessed the first conquest of outer space.
It consists of a relative vacuum made up of a low density of particles (particles).
Space contains matter and dark energy, too.
It takes a speed of 28,100 km/h (17,500 mph) to reach the lowest orbit around the Earth.
Outer space is a challenging environment suitable for human exploration due to the dangers of double vacuum, radiation and zero gravity.
Its area is measured in light years.
Information about planets and space
Among the most important information that can be mentioned about space and planets, according to the British “Britannica” website, is:
Outer space contains a lot of gases, as well as small dust plankton, some particles and radiation, as well as magnetic and electric fields.
Hydrogen and helium molecules are widely spread in stellar mediums, and make up 98% of the molecules, and despite the presence of other elements such as oxygen, nitrogen and carbon, their density is less than hydrogen and helium.
– made up Solar Group Of the 8 planets, which are: (Mercury – Saturn – Earth – Mars – Venus – Jupiter – Neptune – Uranus).
The planet Mercury is one of the five planets that were known in the past, and the ancients called them the wandering stars, and the distance that separates it from the sun is 57,910,000 km, which is equivalent to 0.3871 astronomical units.
Venus is named after the Roman goddess of love, and its distance from the sun is 108,200,000 km, which is equivalent to 0.723 astronomical units.
The Earth is the only planet that contains water and there is life on it, and its distance from the sun is 149,600,000 km, which is equal to one astronomical unit.
The planet Mars is very similar to the Earth in shape, and the distance that separates it from the sun is 228,000,000 km, which is equivalent to 1.524 astronomical units.
Jupiter is a huge ball of gas that is about 300 times the size of the Earth, and its distance from the Sun is 778,340,821 km, or about 5.2 astronomical units.
Saturn is the sixth closest planet to the sun, and it can be seen with the naked eye, and its distance from the sun is 1,427,000,000 km, which is equivalent to 9,539 astronomical units.
The planet Uranus is the third largest planet in the solar system in terms of diameter, and the fourth in terms of mass, and its distance from the sun is 2.871 billion km, which is equivalent to 19.19 astronomical units.
The planet Neptune is the farthest from the sun, and it is a dark icy giant planet, its distance from the sun is 4.497 billion km, which is equivalent to 30.06 astronomical units.
scary information about space
Among the frightening information that can be mentioned about space:
– Too silent.
The size of the Earth is no greater than the size of the storm in Jupiter.
It has a lot of aliens.
Something unknown is swallowing whole galaxies.
The latest information on space
There is information about space that many people do not know, namely:
5 planets outside the solar system that may be habitable have been discovered.
A strange solar system has been discovered, and it is believed to have a habitable planet.
Water cannot exist on the Moon in a liquid state: either ice or water vapor.
Space has a distinct odor explained by astronaut Don Pettit, which is similar to the odor from metal fire or fumes from welding.
– There is no sound in Outer Space.
