Chapter 911

Because he can't even imagine what kind of technology a spaceship needs. The reality is not a science fiction movie. It's impossible to make a cool technical name to say that we can launch a war across the river system.

The ngc3603 nebula, where the small black hole is located, is far enough away from the solar system, because if it is close enough, it will not take them to explore for so long to find it, and only if it is far enough away from it can it be found out.

For the relevant situation of the galaxy, Lei Tiantang is also aware of it. Although from the perspective of the whole universe, the galaxy is a common small galaxy, but it is also a huge one for human beings, so far, we can only have a preliminary understanding of it!

The Milky way is a flat disk with thick middle and thin edge. Its main part, called the silver disk, is a vortex structure.

Its total mass is about 1 trillion times that of the sun, its diameter is about 100000 light-years, its center is about 10000 light-years thick, and its edge is about 3000-4000 light-years thick. Outside the disk is a sphere of sparse stars and interstellar material, called the silver halo, with a diameter of about 100000 light-years.

A close look at the Milky way reveals that the Milky way has four spiral arms: Orion, Perseus, Sagittarius and the 3000 second gap.

The solar system revolves around the center of the Milky way at a speed of 250 kilometers per second for about 250 million years. The sun is about 27700 light-years from the center of the Milky Way galaxy, inside the spiral arm of Orion.

The human horse arm is divided into two parts. The part that bends outward from the center of the galaxy is the human horse arm (horse stick), and the part extending outward is the bottom arm of the boat. According to the data provided by Kuafu, the body of the small black hole is here!

"Perfect!!! Thank you for your efforts Lei Tiantang said excitedly.

Looking at the gorgeous Nebula where the small black hole itself is, he couldn't help saying in a dreamy voice, "Hello, little black hole!"!!! I finally found you

Understand ah, my boss suddenly become so sentimental, Kuafu can still understand his mood, he said with a smile: "don't thank the boss, this is what I should do!"

After a pause, we amplified the data of ngc3603, and then introduced: "the dazzling light from young and big stars penetrates through the curtain of gas and cloud, and the strong light and wind of stars create the appearance of the nebula.

New stars are being bred in this region, which can be called the cosmic factory. According to our data, the mass of gas contained in ngc3603 cloud is not more than 400000 times that of the sun estimated by our data on earth, but about 450000 times.

Of course, this also has something to do with the detection distance and means. Our detector must be more accurate in detecting the data at close range on the body of the small black hole.

So far, stars are still forming in the nebula where the black hole itself is located. In previous observations, the company's astronomers have observed about 60 clusters of gas and dust that will eventually form new stars under gravity.

Of course, this data is certainly not in line with the data we have detected in the nebula. For example, boss, you discovered the big star explosion before. In addition, the star seeds planted by you before will produce new stars in the near future. All of these information will take about 22000 light-years for our detectors on the earth to see.

That's why we're only now able to locate a small black hole based on the data detected by our detector on the side of the body.

We should know that the location of ngc3603 nebula is a cantilever distance from the position of our solar system. There are many big differences in the sky that can be seen through the detector from these two positions. Although we are all in a river system, the sky data we detected from the small black hole is basically a complete stranger to us The stars are in the sky.

This time, I was able to locate it successfully, mainly because I successfully found several neutron stars in the galaxy that we are very familiar with from the detection data collected this time, so that we can determine the position by them.

Then I determined the cantilever of the galaxy where the nebula was located, and then I determined the location of the earth based on the number of neutron stars we had positioned ourselves on the earth side.

And the reason why we can determine its location until now is also inseparable from the harsh environment of nebulae. In addition to the thick and thick nebulae blocking our many detection methods, the existence of these stars is also an important reason.

All the stars in the nebula are almost the same age, 1 million years old, but it's only a blink of an eye compared to our sun and solar system, which has a life span of 5 billion years.

According to our data from the small black hole itself, stars in ngc3603 show different growth stages and volumes. Through these, we can analyze the different life cycle processes of these stars.

When some stars have just begun their journey of life, others have come to an end. This unique phenomenon is mainly caused by the mass of the stars: the massive stars are usually very bright and hot, and burn faster than the lighter, darker and cooler stars.Most of the stars at the center of ngc3630 are of the same mass as the sun, but the most striking are the giant stars that are nearly old. These stars are expected to die out of the big bang and become supernovae, as you've seen, boss.

And now we know that the very large star we observed in the ngc3630 cloud where the black hole itself is located is the largest star in the galaxy that we have detected on the earth side!

Scientists on this side of the earth have long found that there is a large star with a mass of 116 times that of the sun in ngc3630 nebula, which is the larger star in the giant binary system "A1". The other star is relatively small, but its mass is 89 times that of Taiyang.

The heaviest star previously discovered is about 83 times the mass of the sun. The "A1" binary system consists of two blue stars that rotate around each other in a period of 3.77 days.

It's just that we didn't know the location of the nebula before, and the data we observed there were quite different from the data we saw on earth about 22000 light-years ago. That's why we ignored this data, not to mention that such stars are not so rare in the whole universe. "
