Asteroids:
Asteroids are mainly rocks or iron vesicles that rotate around the sun. They are the largest in an area like the donut between the rotation path of Mars and Jupiter. Scientists believe that asteroids could not be combined into another planet due to Jupiter's planetary attraction. The size of the largest asteroid is estimated at about 940 km. The asteroids, located some 28 million miles from Earth, are known to be dangerous. They often cross the Earth's orbit. As a result, there is a possibility of collision many times. That is why many computer programs are employed to identify and warn them.
Aurora:
Aurora is a colorful light show on the north and south poles. Aurora is found in Alaska and other northern states of America. They are seen about 25 times a year. Aurora is usually white or green, but may also be yellow or reddish. The aurora is seen when charged particles from the sun's black line (flanker) and solar flares excite light gas at the top of the surface. In fact, the gases are oxygen and nitrogen.
When the charged particles collide with them, they become electrons leaving the electrons, these radiations leave radiation. This is what we see as Aurora. Aurora is less commonly seen in winter. Now the question is, why is it seen only in polar regions? The earth's magnetic field distorts the charged particles from the black line of the sun and brings it to the poles in two poles of the earth's magnetic field.
Blackhole:
The black hole is the most mysterious object in the universe. Some places in the universe create such a powerful gravitational force that it pulls almost anything that moves around it, whether it's a planet, a comet or a spacecraft, so a black hole. The physicist named John Wheeler the black hole. Why? Because the black hole's gravitational force is so high that even light (photons) cannot come out of its attractiveness. In 1916, Einstein, with his general relativity theory, believed that a black hole could exist.
And in 1994, the innovators proved that there is a black hole. This is not science fiction. German scientist Karl Schwarzschild shows that any star could turn into a black hole in 1916. If the radius of the sun (8,64,950 miles) shrinks to a minimum of 1.9 miles, then the sun will turn into a black hole. He was able to measure the radius of the event horizon. The horizon of the event is the radius of the area around which the black hole will be affected. Scientists first noticed that X-ray radiation is being emitted from a star called Cygnus X-1. In 1971, the first X-ray satellite, the world's first X-ray source, was shocked to find out that the source of the X-ray radiation was coming from a very large but invisible object.
One of the hallmarks of Black Hole is that when the enticing galaxy comes around, it absorbs the galaxy or any cosmic object in a spiral way (WAY). It is very much like if leakage is slightly below the level of a table, then if a ball is left on the table, it will rotate around the leak at one time.
Black Hole is actually a dead star. The star means a bright star. Those who have the light. For example - the sun. Chandrasekhar Subrahman, an outstandingly talented scientist in India, has set a limit on who can be a black hole. That is, all the more than 1.5 percent of the mass of the sun, when they run out of fuel, shrinks themselves into a finite volume but will become a black hole of infinite density. The rest will be pulsars or neutron stars.
Comet:
Comet is a small asteroid that causes the cloud of mist to come when the sun comes closer. They often produce a long bright tail. They can be seen through the telescope while passing through the sun. However, the great comet is seen from around the world in 1910. Some of the comets such as Seki Line, Ikea Seki, Arend Roland, West, Hayaku Takaya, Haile Boop, Halley's Comet, Schnagelrap-Mariani.
Scientists believe that the comet acts as a brick block, creating Uranus and Neptune 4.6 billion years ago. It does not change when the comet is away from the sun. Do you understand what that means? This means that scientists also say; The comet that awaits many ancient compounds, elements, and many unfamiliar mysteries.
Constellations:
Constellation is another mystery in space. Have you noticed that the stars in the night sky can be found in the sky if you want a giant elephant, or an ancient Greek hero, or the face of a lion? Thus it is likely that these ancient Greek myths originated. They thought that the gods were Zeus, Apollo, Hades, Hercules, etc. in the sky. The ancient Greek man Ptolemy discovered 48 constellations in the sky. Currently, 88 are found. Some constellations are seen from the Northern Hemisphere and some only from the Southern Hemisphere. But the zodiac constellation can be seen from two poles.
Constellation is also astonishing to scientists. But they are not myths, they are just as important as the new stars. Download the Stellarium software from Ubuntu / Linux Mint's Software Center and continue. The three-dimensional world of everything in space is given. And you can see what the sky looks like in different parts of the world. And Constellas will be shocked
