In recent days.

The space agencies of several major space powers in the world have discovered a strange space phenomenon.

Stars and Stripes Space Administration (SASA), Office of the Administrator.

Subordinates from the Satellite Detection Department report:

"Over the past two days, several of our communication satellites, three scientific exploration satellites, and two cosmic high-energy physics observation satellites, a total of more than ten satellites, have received more than one high-frequency shortwave signal.

The signal has a frequency of 160 GHz and a regular, orderly waveform, which seems to contain some specific information."

"Are you sure it's 160 GHz?"

Robert Parsons, the director of SASA, a white man in his fifties and a physicist by training, said with surprise, "Electromagnetic waves of this frequency band can generally only come from the interior of stars, or from pulse signals emitted by weak neutron stars."

It is not that humans cannot manufacture electromagnetic signal transmitters with a frequency of hundreds of GHZ, but the radiation damage is too great and the practical value is not high.

The communication satellites launched into space by various countries mostly have frequencies ranging from a few megahertz to several hundred megahertz.

Artificial satellites operating at frequencies exceeding hundreds of GHz are unprecedented, so they are ruled out first.

"Mr. Parsons, we've discovered that these shortwave signals have very complex patterns. They're definitely not random stellar radiation or overly regular pulse signals. Their characteristics are more like those of a man-made signal!"

The scientist reporting the situation said excitedly, "This is extremely rare! This may be the first time in decades of human space exploration that we've received such a unique signal, one that seems to contain some kind of information, and we receive dozens of them every day."

Robert sat up straight, his expression gradually becoming serious. "Can you organize some people to decipher that message?"

"Experts are already working on deciphering it, but the mysterious signal is too short and lacks regularity, making it very difficult to decipher."

"Then arrange a few more people!"

Robert stood up from his office chair. "Perhaps the most significant event in the history of human spaceflight development lies within those mysterious shortwaves!"

"Yes, Mr. Parsons."

…

Except for NASA.

In recent days, the European Space Agency (ESA), the Republic of Mauritius Space Agency (RFSA), and even the space agencies of the three island countries and India, have received mysterious shortwave signals through their communication satellites or space science satellites in space.

After analysis by scientists, these institutions realized that they might have discovered big news.

"Among the communication satellites launched by humans, no one can currently emit such high-frequency radio signals."

"The possibility of it coming from the ground has also been ruled out, as high-frequency shortwave waves have difficulty passing through the ionosphere."

"The only possibility is: these signals come from an unknown alien civilization!"

"There are other intelligent civilizations in the Milky Way! We are not the only ones."

"Mysterious shortwave signals prove that extraterrestrial civilizations exist somewhere unknown."

"This is the most significant discovery in over 70 years of human space exploration, and in the hundreds of years of development of astronomy and cosmology!"

Some scientists are thrilled.

If it weren't for the strict prohibitions required by science that forced them to exercise restraint, they would probably have been impatient and reported the matter to the news media, creating explosive news.

Given the nature of the news media, after hearing the scientists' exciting descriptions, they probably immediately came up with eye-catching headlines such as "Humanity Hears Alien Civilization Broadcast for the First Time" and "Aliens Confirmed to Exist" to increase the number of clicks on the news.

However, several major space powers in the world have heard the mysterious radio signal, but they are unable to locate the specific source of the signal and are unclear about where the aliens are.

It could even be a mistake.

Taking this into consideration, the scientists from these space agencies chose not to make it public for the time being and to conduct further investigation and research.

…

The other side.

The Xia National Space Administration (XNSA) is one of the world's top two aerospace agencies in terms of both scale and technical strength.

The past two days have been filled with a strange calm.

Inside the senior conference room.

Yang Wei, the director of the Space Administration and a former astronaut, was silent for a moment before tapping his desk and saying, "So, the dozens of mysterious signals picked up by several of our scientific satellites are coming from Gambia's first domestically-built satellite?"

"From the five-kilogram satellite that was launched into space three days ago aboard my country's Yuanzheng-2C rocket?"

"That's impossible!"

An expert immediately shook his head vigorously. "Currently, there's no technology that can transmit 160GHz high-frequency shortwaves from a five-kilogram device, and the development is intermittent and random. This is simply beyond our comprehension!"

"good,"

Another expert nodded in agreement: "Even if Blue Mercury has such technology, it can only be the United States or the Great Mao Empire, and it definitely cannot be Gambia."

He really wasn't despising the Gambia, but anyone with a bit of common sense wouldn't believe that the Gambia people could master such powerful black technology.

"Actually, a week ago, an engineer named Zhang Xiaobo from the Aerospace Science and Technology Company sent us an email saying that Gambia's satellite was exceptionally advanced and that we should proactively cooperate with them. He also hoped we could persuade them to temporarily suspend the satellite launch so they could study the satellite's technical principles and then launch it for free... The content of this email was considered ridiculous, so we immediately rejected it and gave Zhang Xiaobo a warning."
