Jakarta –
Some ordinary people might think that in space there are only stars, moons and planets. However, in fact it’s not only that.
Space is vast and there are many amazing things and strange things in it. With advances in technology, humans have learned more facts about outer space.
Where is space, what color is it, and what is there? For further information, see the explanation below.
Understanding Outer Space
Quoted from the Target tech page, space is a space term or concept in an area that refers to various phenomena in science, mathematics, computing.
Outer space is the region outside a planet’s atmosphere. From Earth, outer space begins about 100 kilometers (62 miles) above sea level.
The line that separates the atmosphere and outer space is called the Kármán line. Another name for outer space is empty space or space (in English).
In fact, most of the universe is empty space or what is called an imperfect vacuum. There is very little matter in space.
Outside the figure is a hard, airless vacuum. So, outer space is very cold.
But there are some stray particles and radiation. Although space itself is cold, it requires special infrared radiators due to the lack of particles to interact with, so it is difficult to remove waste heat from the spacecraft.
In this case, outer space simply refers to the area between planets. While the universe also includes planets in it.
What’s in Outer Space?
Reporting from the Qualitative Reasoning Group page, in outer space there are clouds of interstellar dust and small particles that form the solar wind. There, there are many isolated particles and hydrogen atoms, which sometimes form nebulae (clouds one billion kilometers wide).
Apart from nebulae and interstellar dust, in space there are also fragments of debris as large as small moons to grains of sand. These pieces of debris are called planetoids and asteroids.
Radio, heat, and X-rays will all reverberate through space, as will light beams. Where, there is radiation exploding in solar flares.
In addition, there is also “space junk” caused by spaceships disintegrating in outer space. The reason is that humans also throw quite a lot of things into outer space around our planet, both satellites and space probes.
There may be similar rings of manufactured goods on other planets far away.
Reporting from the NASA Space Place page, if you are in the middle of a clear night, you might also be able to see the beautiful expanse of the Milky Way stretching across the sky.
Interesting Space Facts
Reporting from the National Geographic Kids page, here are interesting facts about outer space:
One million Earths can fit inside the Sun. In this case, the sun is considered an average-sized star. Comets are remnants of the creation of the solar system about 4.5 billion years ago. It consists of sand, ice and carbon dioxide. Humans will not be able to walk on the planets Jupiter, Saturn, Uranus or Neptune. The reason is, these planets do not have solid surfaces. Recently, NASA revealed that there is water that flows periodically on the planet Mars. This fact has been dismissed for years, with Earth believed to be the only planet in our solar system that has liquid water. If we fly a plane to the planet Pluto, the journey will take more than 800 years of Earth time. Space trash is man-made objects orbiting the earth, where they are no longer useful. In fact, scientists estimate that currently there are around 500,000 pieces of space debris, including fragments of rockets, satellites, and everyday objects dropped during the construction of the International Space Station. The asteroid is only the size of a car and enters Earth’s atmosphere (approximately once a year ), but the asteroid burned up before it reached our earth. The highest mountain known to humans is on an asteroid, namely Vesta. Vesta is 22 km high, which is three times higher than Mount Everest. The number of stars in the universe is more than the grains of sand on all the beaches on Earth, or at least one billion trillion. On Mars, the sunset will appear blue.
That was an explanation of what outer space is and what is in it. Hopefully this article can increase your knowledge, detikers.
