Realities of the Universe

Hello believe it or not we still know little about the space by modern science, but from the little we know there are some extraordinary and amazing things.

This is my list of what fascinates me in the universe.

Weight
If I put Saturn in water it will float Saturn density is so low that if we put Saturn in a giant cup of water it would float. Saturn's density is 0.6187 grams per cubic centimeter at the equator Saturn It has a 60,268 KM radius which means that you You need a very large glass of water to do the test

Constantly on the move
We are constantly moving in the space at a rate of 530 kilometers per second.

Source
The Milky Way is rotating at a 225 kilometers per second,

Source
Furthermore the galaxy is traveling the space at 305 kilometers per second

Source
this means that we are traveling to full speed of 530 kilometers per second or be in a minute you It will be about 19 000 kilometers away from where you were

Goodbye friends
The light is moving away from the earth, each year the moon moves away about 3.8 cm from earth

Source
this is caused by the effect of the tides,

Source
Therefore, our planet is decreasing rotation approximately 0.002 seconds per day every century Scientists do not know how the moon was created but the most accepted theory suggests that a large object such as Mars hit the earth causing the Moon it was originated

Ancestral light
The light that reaches the Earth currently has 30,000 years

Source
the energy in the sunlight we see today

Source
It began in the sun core 30 thousand years ago ago he spent most of this time passing through the dense atoms that make the sun

Source
and just eight minutes to reach us. The temperature at the sun's core is 15,000,000 C

Source
All energy produced by fusion in the core must travel through many successive layers to the photosphere before escaping into space as sunlight or kinetic energy of the particles.

Solar diet
The sun loses about 1 billion kilograms by solar winds,

Source

Solar winds are charged particles which are injected from the upper surface of sunshine owing to the high temperature of the crown and the high kinetic energy particles through a process that is not well understood until this moment

Source
out of curiosity did you know that a sun energy pinhead is enough to kill a person at a distance of 160 km

The Big Dipper is Not a Constellation

The big dipper is not a constellation is an asterism

Source
many people consider the big dipper a constellation but is actually an asterism

Source
an asterism is a pattern of stars in the sky

Source
which is not one of the 88 constellations officials they are also composed of stars that are not physically connected to each other and may be separated by large distances

Source
A asterism can be composed of one or more star constellations

George Star
Uranus was originally called George Star

Source
When Sir William Herschel

Source
Discovered Uranus in 1781 gets the honor of naming it he chose to George star in honor of his King George the Third

Source
Uran was also the first planet be discovered using telescopes

Extra Moons
The earth have at least 4 Moons

Source
Ok this is not true but is very close in 1986 Duncan Waldron

Source
He discovered an asteroid of five kilometers in diameter

Source
In an elliptical orbit around the sun with periods of rotation almost identical to Earth, for this reason the asteroid and the Earth seems to follow one another.

Source
the asteroid is named called Cruithne in tribute to an old group of people of Scotland because of its relationship with the earth is often referred to as the Earth's second moon Cruithne is weaker than Pluto requires at least a telescope reflector of 12.5 inches

Solar music
The activity of Sunspots

Source
can be the main reason for the beautiful sound of stradivarius violins. Antonio Stradivari

Source
It is considered the largest luthier of history, he lived in Italy between the 17th and 18th centuries, The scientists have been unable to discover what has their violins that makes them so incredible but they know that the timber used is a factor that contributed

Source
In the years 1500 to 1800 the Earth has gone through a little ice age

Source
Mainly due to the increase in volcanic activity

Source
and decrease in solar activity as a result of cooling the types of trees that Stradivarius used for his violins were particularly difficult due to the slow growth, hard wood is especially good for making violins, it is very likely that if Stradivarius had lived in a different era their violins would not be valued as they are today

Cold welding
If two metal parts touching in the space will be permanently attached,

Source
This may seem unbelievable but this is True, two pieces of metal without any coating on them will form a single piece in the vacuum of space, it does not happen on Earth because the atmosphere put a layer of oxidized material between the surfaces, this may seem like a big problem in the international space station

Source


Source
but like most of the tools used came from the land are already coated with the material, in fact the only evidence so far has been in experiments designed to provoke reaction this process is called cold welding.

And I reached the end. I hope that you enjoyed!
