11 Facts About Space You Didn't Know

1- The North Star will eventually change

The northern star is used for navigation, and it is a fixed point in the sky that appears at night, but it will change, but not in our life.  The Earth rotates the rotating star, and for this, the Earth's axis is tilted.  And he is currently referring to Polaris.  But in 13727 it will be heading towards the star of Vega.  And Vega was the North Star in the year 12000 BC.

2- The crew of the Apollo spacecraft did not have any life insurance

Assuming that the 3-man crew (Armstrong, Aldrin, and Collins) did not return safely from the Moon, then their lives were not covered by any life insurance policy.  So before their trip, the three signed some photos that could be sold in the event of their death.

3- The minerals in space stick together

In a vacuum like space, when two pieces of the same metal touch each other they bond together.  This process is called cold welding.  This does not happen on Earth because of the oxygen in our environment, but it may be used during some manufacturing processes.  It's something to consider, but it's not usually a problem because the astronaut's tools retain a layer of oxide even after leaving Earth.

4- The most distant thing man can ever do is Voyager 1

In 1977 Voyager 1 and 2. Their primary mission was to visit Jupiter and Saturn.  Voyager 2 continued its journey to Uranus and Neptune.  Voyager 1 made its way through interstellar space.  Voyager 1 is farther from Earth than the distance between the sun and Pluto.  Both vehicles carry a gold register on board, which will act as a time capsule for Earth.  These records include greetings from the ground as well as various types of music.  It also has noise from rocket engines, the sea, some people talking, animal sounds, and a lot of pictures, all of which summarize the Earth.  Jimmy Carter, President of the United States at the time, said, "This record represents our hope, our resolve, and our goodwill in the world and the vast space."  These messages are recorded as electronic impulses that can be translated into written words.  If any aliens find this they will enjoy it.

5- There is a volcano on Mars three times larger than Mount Everest

The volcano is 600 km in width and 21 km in height. Olympus Mons is a volcano on Mars and maybe active, according to scientists.  And this summit is the highest among all the planets.  But there is a summit of Resilvia on the asteroid Vesta and it is about 22 kilometers long.

6- The moon was part of the earth

And this theory lies in that when the planet was relatively young, it was hit by a giant body and this collision broke off a piece of Earth that went away and the moon arose.  Then this piece began to revolve around the Earth as a result of the pull of gravity.

7- There is water floating in space

Astronomers have found a huge cloud of water vapor that fills 140 trillion times the amount of water in Earth's oceans.  This is about 10 billion light-years away, making it the largest water discovery ever.

8- The footprints will remain on the moon's surface for 100 million years

The moon has no atmosphere, which means there are no winds to erode the surface and no water to wash away the footprints.  This means that the Apollo astronaut footprints, plus spacecraft footprints and discarded materials, will exist for millions of years.

9- There might be a planet made of diamonds

This remains impressive, but research conducted by Bell University scientists indicates that the rocky planet called Cancri E55, a planet whose radius is twice the radius of the Earth and its mass eight times greater, may have a surface made of graphite and diamonds.  It is 40 light-years away, but it is seen with the naked eye in the constellation of Cancer stars.

10- Space is completely silent

There is no atmosphere in space, which means that sound has no means or medium to navigate to be audible.  Astronauts use radios to keep in touch while in space.  Where it is possible to transmit and receive radio waves.

11- Neutron stars may orbit at a speed of 600 times per second

Neutron stars are the densest and smallest stars in the known universe.  Although its radius does not exceed 10 kilometers, its mass may be several times more than that of the sun.  It can spin at speeds of up to 60 times per second after being born from the explosion of a large star.  It has been known to rotate about 600-712 times per second due to its physical properties.
