Astronomers have discovered the fastest star in the universe - "XRG005", which flies in interstellar space at a speed of 24,000 kilometers per second. You should know that according to the length of the 940 million kilometers of the Earth's orbit of , the Earth's orbit is only 30 kilometers per second. "The speed of is so fast that the world is shocked." is one of the clearest and most accurate descriptions of his crazy speed, trajectory and surrounding space environment.
Compared to the sun, there are many super-speed stars in the universe. The stars around the super-large black holes near the galaxy nucleus seem to be dancing on steel wires. If you are not careful, you will face the fate of being swallowed by the black hole. In order to escape the desolation, S2 had to speed up its revolution and crossed a distance of 113 billion kilometers in less than 16 years. It seems that the fates between stars are as different as humans!
Origin of stars
Stars are the product of nuclear fusion . The continuous nuclear fusion is also the main way to produce star mass . The inside of the star seems to be a huge nuclear reactor . The elements are constantly fusion, which allows the star to continuously generate high temperatures and scatter energy into the universe.
star main sequence star stage usually has three types:
red dwarf , The mass and temperature parameters are the smallest among stars. Because the radiation released outward is too weak, it is difficult for the naked eye to find its existence. The star closest to the earth Proxima is a typical representative of red dwarfs. In the era without astronomical telescope , humans have never discovered that there is a star accompanying the solar system only 4 light years away. Of course, it is precisely because of its weak nuclear reaction ability that the lifespan of a red dwarf is much longer than that of the sun and can steadily float for hundreds of billions of years. According to astronomical statistics, 70% of the stars in Milky Way are all red dwarfs.
Yellow dwarf is generally considered the second type of star . Our sun is a typical yellow dwarf. Unlike red dwarfs, the lifespan of red dwarfs is different from that of hundreds of billions of years. The time when the hydrogen fusion in yellow dwarfs is completed, the helium flash described in "The Wandering Earth" will occur. A large amount of helium begins to fusion nuclear, and the star itself will expand accordingly. Entering the red giant stage of the last year of the star, the expanding star will swallow the planets surrounding it, and the entire galaxy will become a ruin.
Blue dwarfs have the highest temperature and brightness among stars. Their surface temperature is enough to melt everything. The brightest stars in the night sky are often blue dwarfs. Vega and Sirius are typical representatives of blue dwarfs. Of course, the passionate burning is destined to not last too long. Because the fusion reaction is too intense, the lifespan of the blue dwarf is only a short billion years. In the universe's star body with billions of years as the basic time unit, billions of years may be just a short moment.
The dullness after glory - white dwarf
When the star consumes the internal hydrogen element and expands from the main sequence star to become a red giant, the remaining helium element continues to fusion and emits light and heat outward, but the helium element will gradually be consumed over time.
At that time, the radiation pressure and gravity inside the red giant will gradually become unbalanced, and a white dwarf will gradually be born in the core of the star. The star starts to cool down slowly due to exhausting energy, and finally the variables slowly, and the color will also turn from red to white to darken, becoming a carbon core floating in space—— black dwarf .
After understanding the concept of stars, we can look at the king of velocity in this star from the perspective of cosmology and astrophysics. According to astronomers, XRG005 may originate from a black hole - this black hole was produced after an X-ray star exploded. The X-ray star is 4.6 billion years old and it moves at a very fast speed like other stars.The complex magnetic field inside a star (similar to gas and dust forming bodies) may appear around it, and the magnetic force generated by different substances will gradually affect its orbit.
The stellar wind blowing outward from stars all the time may be the main resistance encountered by the stars in the universe when they move, which is also the reason for the dangers in the universe. Science is now unable to determine whether the reason why XRG005 is the fastest star in known galaxies is due to the influence of star wind .
We don’t know how many secrets are hidden in the deep starry sky. Perhaps human curiosity is the most fundamental driving force given to us by God.
How deep is the ocean? What exactly is there in the deep underwater world?
How big is the complete universe? Do there really exist cosmic boundaries?
The parent star of "Three-Body Problem" was discovered? Will there be life on Proxima Centauri?
