After arriving near the wormhole, the Yongye spacecraft passed a few days of orbit and attitude adjustment.

"Everyone please get in place. After ten minutes, the spacecraft Yongye will cross the wormhole."

"The tenth attitude control engine starts ..."

"Starting of No. 2 capital adjustment engine ..."

"Starting the No. 5 capital adjustment engine ..."

The Yongyong spacecraft slowly turned the huge hull and aimed the bow at a wormhole 100,000 kilometers away.

"Pay attention to maintaining output power ..."

"Good attitude, you can start the main engine ..."

"Eternal Night ... Forward Three ..."

The tail of the Hall thruster emits a blue-purple gloom, ejecting a high-speed plasma stream behind him, and the spacecraft starts to start at full power and enters an accelerated state.

"One hundred thousand kilometers from the wormhole!"

"50,000 kilometers."

"Ten thousand kilometers."

"One thousand kilometers."

"Ten kilometers."

"Countdown to contact, ten, nine, eight, seven, six, five, four, three, two, one ..."

Xi Pang Xuelin They are located in the front third of the spindle propeller of Yongye.

Therefore, they can clearly see that the moment the ship's bow of Yongye was in contact with the wormhole, the dark space on the surface of the wormhole was thrown into a stone like a calm water surface, emitting waves one by one.

But this scene stayed in Pang Xuelin's eyes for less than two seconds, and then, they also plunged into this strange world.

The soft white light emitted by the lights in the spacecraft was suddenly broken down into colorful colors.

的 The space around the bridge has produced a double-layered shadow, and all the equipment in the spacecraft has given him a great sense of depth and tolerance.

Although Pang Xuelin has experienced the depth of the infinite space of the high-dimensional space inside the wormhole, when he experiences this scene again, he still has a dreamlike feeling.

Murphy, Billy, Little Brand, and others are even more so. They fixed themselves on the seat one by one, looking at everything in horror.

Fortunately, this process only lasted a few minutes.

I was much shorter than the last time Pang Xuelin took the rescue capsule to cross the wormhole.

As the ship's hull trembled slightly, those colorful lights instantly dissipated, and the objects in the ship that showed an endless sense of depth seemed to be dominated by some force and instantly restored to their original state.

Out of the porthole, a golden light passed in and shone on the podium.

Xu Pang Xuelin unfastened his seat belt and came to the porthole first.

Murphy, Jr. Brand, Dr. Mann, Billy, Emmond and others came behind him.

"my God!"

Dr. Mann couldn't help but draw a cross on his chest, and looked at the black hole in the distance that was emitting hot light radiation into the universe, exclaiming.

"Kaguntuya!"

Said Murphy aside.

Xi Pang Xuelin nodded, and what appeared to them was a super-large black hole composed of the body of the black hole, light, and accretion disks.

The black part in the middle is the shadow of the black hole, which is about twice the horizon.

A thin circle of light outside the puppet is the photon circle of the black hole.

The huge accretion disk rotates around the black hole. The accretion disk is composed of various materials and gases that rotate at a high speed and slowly fall to the black hole. It is extremely bright due to strong collision and radiation.

The accretion disk above the black hole looks larger and brighter than the bottom.

Pang Xuelin knows that the upper part of the black hole is actually the far end of the accretion disk, and the lower part is the bottom of the far end of the accretion disk. The gravitational field of the black hole distorts the path of light propagation, and this is a strange phenomenon.

NASA has already launched detectors into this world before, and finally concluded that the mass of this black hole is equivalent to 100 million times the mass of the sun, and its radius of sight has reached 295 million kilometers.

You must know that an astronomical unit, that is, the distance between the earth and the sun is almost 150 million kilometers. The horizon radius of this black hole is equivalent to two astronomical units, so imagine how huge this black hole is.

At least in Pang Xuelin's impression, the silver heart A Sagittarius A black hole is more than 40 million times the mass of the sun.

Only the black hole in the core of the Andromeda Nebula has such a volume and mass.

But the Kagantuya in front of him is definitely not the black hole in the Andromeda Nebula.

The reason is very simple. On a clear night on Earth, where the light pollution is not serious, we can look up at the starry sky. Most of them are stars that are relatively close to the solar system. The nearest distance is the neighboring star, about 4.22 light years. Nanmen's two double stars (the triple star system with neighboring stars) are about 4.37 light years, Barnard is about 6 light years away from us, and Sirius is about 8.7 light years away from us. Such star density is not sparse, but if and Compared to the position of the silver heart, it is far worse.

If you count the number of stars per cubic light year, there is only about 0.004 stars per cubic light year in the space near the sun. Generally, the star density in a globular cluster is considered to be relatively high. The star density there is about 2 per cubic light year. Stars, equivalent to 500 times the density of stars in space near the sun.

However, the density around the silver heart is higher than this density. It is said that the density of stars there is as high as 289,000 stars per cubic light year, which is 72 million times higher than the density of stars near the solar system.

Under such a star density, if the earth is located near the silver heart, we can probably see millions of stars brighter than Sirius. The brightness at night is about the same as when the sun shines during the day.

If it is a black hole in Andromeda M31, it will be even more exaggerated.

But there was no such scene in front of him.

The Yongyong spacecraft is at least 10 billion kilometers away from Kaguntuya. Pang Xuelin can clearly observe the sparse starry sky around Kaguntuya, far from the star density of imagination.

Near Kagantuya, the only thing that can be observed is a dark red planet the size of a ping-pong ball in the distance and another main sequence star similar to the sun.

The two stars together with Kaguntuya constitute a Samsung system.

But because Kagantuya's mass is too huge, these two stars are like ordinary planets, making a circular motion around Kagantuya.

好 "Well, everyone returned to their posts, released the detection satellite, and carried out a comprehensive survey of our galaxy."

"I understand!"

With the order of Pang Xuelin, everyone in the spacecraft has entered an unprecedented busy state, especially the visible light telescope and radio telescope carried by "Eternal Night". Scale observations.

But the observations surprised everyone.
