With the improvement of astronomical observation technology of the Alliance for Human Innovation, the area around the solar system within a radius of 100 light-years has been re-observed.

In fact, the reason for this is mainly the order of the Council of Alliances, mainly to monitor alien civilizations, if there are alien civilizations within a radius of 100 light years in the solar system, then the possibility of conflict between them and humans is very high.

If their condition can be confirmed in advance, humanity can prevent it from being raided by alien civilizations in the solar system. And Virgo 61, which is only 27.8 light-years away from the solar system, must be one of the targets to focus on.

Virgo 61 has a total of 7 planets, which are arranged at a distance from the star, which are 61b, 61c, 61d, 61e, 61f, 61g, and 61h.

Among them, three planets, 61b, 61c, and 61d, were discovered before; The four pieces 61e, 61f, 61g, and 61h were discovered recently.

The lower limit of mass of 61b in Virgo is 5.1 times the mass of it, so it is a typical super blue star. It is only 0.050201 AU away from its parent star and has an orbital eccentricity of 0.12. Virgo 61b was discovered on 14 December 2009 by the Keck Observatory and the Anglo-Australian Observatory using the radial velocity method.

As for Virgo 61c, d is a gas planet (Jupiter-like), 61c has a mass about 19 times that of blue star, and there are no large natural satellites; 61D is about 25 times the mass of Blue Star and has six large natural satellites.

The four planets 61E, 61F, 61G, and 61H, according to the observation results of astronomical telescopes, 61E is about the same mass as Blue Star, and 61F is about 0.7 times the mass of Blue Star, and 61G and 61H are very likely to be dwarf planets.

Huang Mude discussed with David and others, and decided to activate the Gaoming Space Telescope to observe the 61c region of Virgo again.

With the assistance of the space station's supercomputer, one of the four primary mirrors of the Gaoming Space Telescope slowly opened the protective plate.

Zhang Xianyue entered Virgo 61C on the holographic computer, and the telescope automatically adjusted the angle and focal length, and soon Virgo 61C entered the telescope's field of view, and Zhang Xianyue continued to take photos.

And David, Zheng Dongjiang, and Huang Mude carefully observed the photos one by one.

"David, there really is a satellite in orbit around Virgo 61c." Huang Mude said as he looked at it.

"But is this satellite too weird? It appeared in the orbit of the moon of Virgo 61c without warning, its volume is about 0.2~0.3 times that of the moon, how did such a large celestial body suddenly appear?" Zheng Dongjiang said puzzled.

David also looked confused, they had already observed a lot of situations in Virgo 61 before, and it was impossible for such a big mistake.

"If it is a satellite captured by Virgo 61c itself, this is also possible, after all, there are many wandering objects in interstellar space." Huang Mude explained.

"It's a real possibility." David nodded.

"No, look at this picture, it's so weird." Zheng Dongjiang suddenly pointed to one of the photos and exclaimed.

David and Huang Mude hurriedly leaned over, David couldn't help but take off his glasses and wipe them when he saw the photo, and after putting on his glasses again, the photo was still the same photo.

"How is that possible? How could it be this shape?"

"A triangle of three spheres is not like a natural celestial body, if it is an oval or a long bar, or even an irregular shape, it is possible, but such a regular three-sphere triangle ......" David was a little overwhelmed.

"String Moon, you continue to observe." Huang Mude commanded.

"Okay." Zhang Xianyue hurriedly replied, obviously she had already felt that she had found something amazing.

Over the next three days, the astronomical observation team gathered everyone and activated the full situation of the observation room Virgo 61, which was in full swing with the four main telescopes.

"It's very likely that it's a satellite or a spacecraft." Zheng Dongjiang put down an observation report and said.

"We re-observed the entire Virgo 61 and found that 61d in the orbit of the third planet and 61e in the orbit of the third and fourth planets all appeared in this kind of triangular moon, if it is only one triangular moon, it can be explained by coincidence, then the appearance of three is not a coincidence." David said with a solemn expression.

"We have to report this news, the alien civilization that can build such a huge satellite or spaceship should not be underestimated." Huang Mude immediately said.

"I agree."

"I agree."

The others nodded solemnly.

……

Shanghai - the temporary headquarters building of the Human Innovation Alliance.

With the sound of hurried footsteps, Fang Dongliang's office door was hurriedly pushed open by a figure.

"Chairman, Minister Wang Tu of the Ministry of Aerospace and Aerospace has sent you a request for intensified communication."

"Take it." Fang Dongliang hurriedly said.

"Yes."

Drip! Wang Tu's holographic projection appeared opposite Fang Dongliang, and the assistant hurriedly exited the office.

"Minister Wang, what's the urgency?"

"I'll cut a long story short, it's about alien civilizations, and I need the chairman to convene a council right away." Wang Tu said solemnly.

Fang Dongliang suddenly felt the seriousness of the matter: "Yes, I'll arrange it immediately." ”

As soon as he finished speaking, he opened the drawer, which was a red holographic computer, quickly entered the password, and inserted his special ID card.

Suddenly, his office changed to the ground, and a holographic conference room was formed in an instant, and inside the conference room was a round table, and around the round table were 13 seats.

Fang Dongliang himself was on one of the seats, and the directors of the other seats were also online. Ten minutes later, there were no one but the unusual throne, and the other 12 seats were already there.

And Wang Tu's figure stood in the middle of the round table, and he said solemnly:

"Three days ago, we at the Gaoming Space Telescope at the New Manila Space Station discovered the presence of unknown bodies on planets C, D, and E of Virgo 61, which are suspected to be satellites or spacecraft, and this is a detailed report."

A holographic document appeared in the hands of the 12 directors, and Fang Dongliang did not look at the document, but asked directly: "How likely is it that it is an alien civilization?"

"More than 90% of them are likely to be extraterrestrial civilizations." Wang Tu replied.

"Is it the Anluo people we found earlier?" Yamauchi asked, putting down the papers.

"It is unlikely that it is an Anluo Xingren, judging from some of the information that has been deciphered so far, the style of the Anluo Xingren's spaceship is different from the alien civilization that has just been discovered." Wang Tu explained.

"How threatening are they to the Blue Star?" Pushkin asked a crucial question.

"This depends on the speed of the spacecraft of the triangular civilization, if they reach the speed of near light or faster, they are a huge threat to us, if they do not exceed 10% of the speed of light, we still have time." After speaking, Wang Tu opened the star map near the solar system.

"The distance between Virgo 61 and the solar system is 27.8 light years, which means that we observed information from 27.8 years ago, and due to the backwardness of our previous observation technology, we cannot now determine whether the triangular civilization is the original civilization of Virgo 61 or an alien civilization."

"Is there a difference between the two?" Kadina, Kazakh, asked.

"The difference is very big, if it were the native civilization of Virgo 61, their spacecraft might not be too fast; If it is an alien civilization, their spacecraft may be very fast, maybe even close to the speed of light or faster than the speed of light. ”

"Why?" Fang Dongliang asked.

"Because of the distance, the closest galaxy to Virgo 61 is Gliese 581 with a distance of 11.5 light years, the second closest galaxy to Gliese 371 with a distance of 15.8 light years, and the third closest galaxy to Centauri A with a distance of 25.7 light years," Wang explained. Without a superfast spacecraft, it would be very difficult to cross more than 10 light-years. ”

"Is the triangular civilization an alien civilization?" Fang Dongliang continued to ask.

"The possibility of foreign civilizations is relatively small, the possibility of native civilizations is relatively large, and we also hope that they are not foreign civilizations." Wang Tu knew that if it was an alien civilization, then their danger would skyrocket.

"Temporarily block the news, you are closely observing the movements of the triangular civilization, what suggestions do the other councillors have?" Fang Dongliang asked, looking around.
