Human science and technology flew 22.2 billion kilometers and took a photo. American astronomer: We should think deeply.

Since mankind entered the era of industrialization, the progress of human science and technology has been increasing day by day, directly at the speed of explosion. Man has created a lot of technology. While making life better and more convenient, human beings have never stopped exploring outer space, and human science and technology are gradually stepping out of the earth and into space.

In 1970s, Titan-3 E Centauri rocket sent Voyager 1 out of the earth with a huge roar. At that moment, it means that the earth opened the beginning of human visit to outer space and took the first step in the long journey of exploring the solar system. This first step was very successful, and it also set off a technological frenzy to explore outer space.

Today, this probe has been flying in outer space for 42 years. Why can a small spaceship fly in space for so long? Won't it run out of fuel? Is it solar energy? Actually, it is not. The detector is equipped with a nuclear-powered battery. The detector itself is not big, so the flight process will not consume too much energy.

However, according to the battery life set by the detector, it is estimated that the nuclear-powered battery will be exhausted in 2025, and according to the flight speed of the detector Voyager 1, it has reached a position about 22.2 billion kilometers away from the Earth. At that time, some astronomers suggested that the detector take a family photo of the solar system.

In the family photos of the solar system, we can see that even the huge sun is only a faint bright spot. In fact, it looks like a bright spot because the sun is the farthest from the detector. Inspired by this photo, American astronomer carl sagan wrote a book. The more people know about the universe, the more they will feel humble and insignificant.

This photo is considered to be one of the most precious photos in the history of human space. It was shot at a distance of 22.2 billion kilometers from the earth. After the energy consumption, the detector will continue to drift in the universe with human awe of the universe and continue to March into deep space, but the existing technology of human beings has been unable to get in touch with it.
