Space and the galaxies, planets and stars it contains are among the areas of interest for many; Therefore, in the following lines, we look at the information about space, with an explanation of the strangest and newest things that are happening in it.
Space information
Before mentioning the information about space and what revolves around it, space can be defined as the space between celestial bodies, and is called the term outer space because it differs from the airspace that surrounds it. LandFurthermore, it is not possible to accurately determine the area of outer space, due to the difficulty encountered by specialized detectors, since long distances in space are measured in light years, which means the distance traveled by light during a year, and of As a result, the area of space is about 9.3 trillion km, according to Sputnik.
There is also a lot of space information that can be mentioned, but the most important are:
The history of space exploration dates back to 1921, the year in which the first conquest of space took place.
It consists of a relative vacuum consisting of a low density of particles (particles).
Space also contains dark matter and dark energy.
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 the double vacuum, radiation, and zero gravity.
Its area is measured in light years.
Information about the planets and space
Among the most important information that can be cited about space and planets, according to the British website “Britannica”, is:
Outer space contains many gases, as well as small plankton dust, some particles and radiation, as well as magnetic and electric fields.
The molecules of hydrogen and helium are widely spread in the stellar media and constitute 98% of the molecules and, despite the presence of other elements such as oxygen, nitrogen and carbon, their density is lower than that of 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 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 equivalent to one astronomical unit.
The planet Mars has a very similar shape to the Earth 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 larger than 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 can be seen with the naked eye and its distance from the sun is 1,427,000,000 km, which equates 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 is a dark frozen 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 cited about space:
– Too quiet.
The size of the Earth is no greater than the size of the storm on Jupiter.
It has a lot of aliens.
Something unknown is engulfing entire galaxies.
The latest information on space
There is information about space that many people do not know, namely:
Five planets have been discovered outside the solar system that may be habitable.
A strange solar system has been discovered and is believed to have a habitable planet.
Water cannot exist on the Moon in a liquid state: neither ice nor water vapor.
Space has a distinct smell explained by astronaut Don Pettit, which is similar to the smell of metal fire or welding fumes.
– There is no sound Space.
