10 amazing facts that will blow your mind
The space is stunning. The enormous amount of that, along with trillions on trillions of things in the billions of galaxies of the universe, is almost incomprehensible to the human mind.
This page is a constantly updated list of the most amazing, amazing and incredible facts about space. Whether it's kids looking to learn more about space, looking for incredible facts for an article, or even if you love space facts for no real reason, that's for you.
1_Space completely silent.
There is no atmosphere in space, which means that the sound has no way or way to travel to hear it. Astronauts use radios to stay connected while in space, where radio waves can still be transmitted and received.
2_ solar is 450 degrees Celsius
Venus is the hottest planet in the solar system with an average surface temperature of about 450 ° C. Interestingly, Venus is not the planet closest to the Sun - Mercury is closer but because Mercury has no atmosphere to regulate temperature it has a very large temperature variability.
3_ There may be life on Mars.
Of all the planets in our solar system (except Earth), Mars is the most likely to be hospitable in life. In 1986, NASA found what they thought might be fossils of probiotic in a rock extracted from Mars.
4_ Nobody knows the number of stars in space.
The sheer size of the space makes it impossible to accurately predict how many stars we have. Currently, scientists and astronomers use only the number of stars within our galaxy, the Milky Way, to estimate them. This number ranges from 200 to 400 billion stars, and the estimated number of billions of galaxies, so the stars in space can not be fully counted.
HALLEYS COMET will not orbit the Earth again until 2061.
Edmund Halley discovered in 1705 the last famous comet in 1986 and appeared only once every 75 to 76 years
6_ Neutron stars can rotate 600 times per second.
Neutron stars are the densest and smallest stars in the known universe, and although their radius is only about 10 km (6 mi) in diameter, they may be several times the mass of the Sun. They can rotate at a rate of up to 60 times per second after they are born from the explosion of a supernova collapse, and they are known to spin at 600-712 times per second due to their physics.
7_ There may be a planet made of diamonds.
As the space facts go, this is very impressive. Research by Yale University scientists suggests that a rocky planet called 55 Cancri e - which has a radius of Earth and an eight-fold mass - may have a surface composed of graphite and diamonds. It is 40 light-years away but visible to the naked eye in the constellation Cancer.
One day on Venus is longer than one year.
Venus has a slow axis rotation that takes 243 days from Earth to complete its day. Venus's orbit around the Sun is 225 Earth days, making the year on Venus 18 days less than on Venus.
9. The moon is drifting away from Earth
Each year the moon is drifted away from Earth by 3.8 cm. Scientists believe that eventually, the moon will emerge from the Earth's gravitational field. However, this will not happen for the next billions of years.
10. In 3.75 billion years, the Milky Way and Andromeda galaxies collide.
In the Andromeda galaxy is approaching the Milky Way - where our solar system is - at a rate of about 110 kilometers per second (68 miles / sec), and ultimately the two will collide to form giant elliptical galaxies.
