Interesting Facts About the Stars

The stars that make the night sky a magnificent place are massive celestial bodies, mostly hydrogen and helium, that produce light and heat in their cores. Except for the sun, all the stars we see in the sky are from Earth. light year away. They are the building blocks of galaxies that we know number in the billions in the universe. Although it is impossible to know how many stars there are, astronomers only In our Milky Way galaxy He thinks there are 200 to 400 billion stars.

Stars so far from Earth have been among the most curious subjects of mankind throughout history. Information about the stars Even in the most limited times, humanity has made various researches in order to reach more. Let’s take a closer look at the stars that formed for the first time in the ‘cosmic dawn’ event, which took place 250-300 million years after the Big Bang.

The most interesting facts about the stars:

• When we look at the sky, we can see up to 2000-2500 stars.
• Stars can be many colors
• there are too many stars
• When we look at a star, we actually see it in the past.
• The larger a star, the shorter its lifespan.
• The farthest star discovered is 28 billion light-years from us
• Stars don’t actually blink
• Most stars are found in pairs

When we look at the sky, we can see up to 2000-2500 stars.

It is impossible to see millions of stars in the sky at the same time on a dark night. The reasons for this are bright enough and enough for us to see them. near they are not. Maximum number of stars a person can see in one night 2,000 to 2,500 will be. With this. this person must have extremely good eyesight and be looking at the sky on an extremely clear night with no rays from the moon or any other source.

Stars can be many colors

The color of the stars we see in the sky can be in various colors, from red to white and blue. Stars with high temperatures, such as the sun, are yellowish-white in color. 12,000 Kelvin stars with temperatures above So any star temperature and color interconnected are concepts.

there are too many stars

In the Milky Way we are in, approximately 200 to 400 billion It is thought to be a star. Perhaps many of them have planets. In the entire universe, about 500 billion Each of these galaxies may be home to as many stars or more as the Milky Way. When we multiply these two numbers together, we get about 2 x 10ˆ23 in the Universe. piece star turns out to be possible.

When we look at a star, we actually see it in the past.

Aristotle is thought to be the first scientist to state that the rays from the Sun must take some time to reach the Earth because it is so far away. Light, 300,000 km per second We can’t see the light from the stars that fast. About the time light reaches the Earth from the Sun eight minutes takes. Rays from another star, Alpha Centauri, reach Earth about takes 4 light years, so its We’ll see what it looked like four years ago. In fact, it may take decades before we see rays from some stars. In fact, the telescopes we use to see the stars actually allow us to look into the past. Another surprising piece of information is that we can still see stars that have been dead for several years. This is also because, It is the continuation of the rays from the stars to reach the Earth.

The larger a star, the shorter its lifespan.

some stars of the sun 150 times It can have as much mass and emit an extraordinary amount of energy. For example, discovered of the most massive stars one about us Located 8,000 light-years away is Eta Carinae. Studies have shown that this star has 150 times the mass of the Sun and emits about 4 million times more energy. The sun has been radiating energy for billions of years and will exist for billions more, while Eta Carinae has probably only existed for a few million years. And astronomers see this star as a supernova explosion They think they will live.

The farthest star discovered is 28 billion light-years from us

The stars we see when we look at the sky have vast distances. The closest star to Earth is located 4.2 light years away. Proxima Centauri. Light from this star takes more than 4 years to reach Earth. If we try to go with the fastest spacecraft ever developed, 70,000 We will have to travel more than a year. If the farthest star James Webb Space Telescope Captured by Earendel. Located about 28 billion light-years from Earth, this star is named after lord of the rings from his character.

Stars don’t actually blink

Light from a star passes through the Earth’s atmosphere, which has many layers with different densities. All this deflects the light, its color and density changes. Especially as a result of aberrations near the horizon, we see stars as if they are blinking. If the stars from the earth’s atmosphere they would not appear to be flashing if they could be viewed from an area where they would not be affected.

Most stars are found in pairs

Contrary to appearances, although all the stars seem to be standing one by one in the sky, many stars are actually in pairs they are found. these stars binary stars known as. A binary star consists of two stars orbiting a common center of gravity. In addition, some star systems can consist of three, four or even more stars. But these star systems are visible from Earth. a single star seen as.
