Since ancient times, humans have continued to explore the universe, from the solar system to more distant galaxies and black holes.
In the process of continuous exploration, mankind has also discovered many interesting planets, but so far, the earth seems to be the only planet where life exists.
For some time, news began to emerge about the search for life on other planets, and Europa and Enceladus were thought to be the possibility.
So, what is the situation on these two planets?
What are the benefits of exploring these two planets?
1. The only planet in the solar system where life exists.
Earth is home to humanity and the only planet in the solar system where life exists, and no other planet seems to have found any obvious signs of life.
In the solar system, the stars of Sika Deer and Jupiter are the most deeply studied, and the colors and shapes of both appear more individual, which also makes people very curious about the surface of these two planets.
In the solar system, Jupiter has four moons, they are Galileo, Europa, Calisto and Io, among which Galileo's internal structure is very similar to the Earth's rock layers, so it is generally believed that Galileo's surface has some lava flow, and there may also be some volcanic eruptions.
Signs of melting ice shells have also been found on Galileo, which reinforces the belief that there may be a liquid ocean and life beneath Galileo.
However, Europa is the place where people are more looking forward to finding life, Europa is an ice moon in the solar system covered with a thick layer of ice with almost no surface features, Europa is very ordinary on the surface, but in 2013, the Mercury probe took a very interesting photo.
This photograph shows a shell on the surface of Europa that looks like a crushed shell on ice, and then some research into this area has revealed that this area may have been formed by ejecting material from the inside, and the ejected material may have a lot of minerals in it, which is very valuable for us to explore other planets in the solar system.
However, no signs of life have been detected in Titan, so is it possible that life existed in Ganymede?
After a long period of research, it was found that the interior of Ganymede is very similar to Titan, which means that it may also have a liquid ocean hidden under the ice.
At that time, many experts and scholars also discussed this issue, and through the study of some methane on Callisto, it was found that these methane traces may have a certain connection with the ocean below Callisto.
In 2017, a large number of people analyzed a vast sea on Titan, and found that there were some strange white light spots on the surface of the sea, which disappeared after a period of time, and many experts and scholars speculated that these light spots may be some ice blocks, or bubbles, and these ice blocks and bubbles may have erupted from the liquid ocean below Titan.
In 2005, the Cassini probe came to Titan, and many experts and scholars also turned their attention to Titan, and after analyzing the wonderful sea on Titan, it was found that there was also a certain amount of organic matter content on Titan, which also made people believe that there may be a certain degree of life under Titan.
2. Do Europa and Enceladus have life?
In the solar system, Europa and Enceladus are also thought to have a certain degree of life, after some research on Europa and Titan, many experts and scholars quickly turned their attention to Europa, they believe that Europa's internal structure is similar to Enceladus, and also has a liquid ocean hidden under the ice, and through some research on Europa, it is found that Europa's thickness is almost the same as that of Enceladus.
Although Europa is also thought to be alive, the lack of a single moon on Europa's surface has slowed down the research of many experts and scholars on Europa, and it is not until 2040 that people's attention returns to Europa.
In 2040, some of the material emitted from Europa was discovered, which is very similar to the material on Enceladus, and some traces of methane were found in the material on Enceladus, and after analysis of these traces, it was found that these traces may be produced by microbial decomposition.
3. Difficulties in detecting Europa and Enceladus.
Because Europa and Enceladus are very far away from the Earth, many experts and scholars hope to be able to detect these two planets through probes, but the distance between Europa and Enceladus is very far, and Europa and Enceladus are also very far from the Earth, so experts and scholars hope to fly to the surface of Europa and Enceladus through probes.
However, at the moment, the dense clouds on Europa and Enceladus can be very thick, which makes it difficult for the probe to penetrate the surface, and Europa and Enceladus are very far away from Earth, so the probe flying on Europa and Enceladus will have to endure a long journey, so the speed of the probe is also very important.
At present, the upper limit of the maximum speed of the orbiter is 16km/s, even at this speed it will take more than ten years to fly to Europa, and it will take longer to fly to Titan, so many experts and scholars hope that space exploration technology can be developed, and the probe will be able to fly faster, so that it can fly to Europa and Enceladus in a shorter time.
At the same time, people also need to provide more data for the probes to help the probes fly better and land better, so that the probes can better explore Europa and Enceladus, and can also find life more easily, thus changing people's understanding of the universe.
epilogue
The discovery of Europa and Enceladus has also provided a new opportunity for human beings to explore extraterrestrial life, and many experts and scholars have also worked hard for the exploration of Europa and Enceladus.
With the efforts of many experts and scholars, people's eyes have been continuously expanded, making human beings more eager to find other planets where life exists.
