Start with a planet hitting the earth

"Mars has pebbles, and pebbles only appear in rivers."

"So, Mars once had water."

"Water is the source of life. Could it be said that there was life on Mars before?"

"Later, for some reason, the life disappeared?"

Chen Yuan looked at the uneven ground on Mars and the huge craters left by meteorites.

"When were these craters left? It stands to reason that with Jupiter protecting these terrestrial planets, they should not encounter such horrific impacts. Unless Jupiter's defenses had not yet been formed at that time."

"In other words, there was water on Mars a long time ago. Looking at the distribution range of these pebbles, it is estimated that a large area of ​​​​the entire Mars was occupied by water at that time."

"Later, Mars became what it is now because of the horrific meteorite impact that destroyed the entire planet."

This is Chen Yuan's speculation. The existence of pebbles can only prove that water existed on Mars before.

As for why Mars became like this later, we can only rely on speculation.

It is now almost certain that life does not exist on Mars at all and is no longer suitable for life.

"I don't want to think about it anymore. Let's go find a satellite and devour it first. When it gets bigger, we can devour this Mars."

Chen Yuan noticed that Mars is also surrounded by two bumpy natural satellites.

These two natural satellites are not as big as the moon at all, and their shape is not as round as the moon. They look like bumpy potatoes, orbiting Mars.

"Does Mars only have two satellites?"

Among the eight planets in the solar system, except for Mercury and Venus, all other planets have their own satellites.

Mars has only two natural satellites. Phobos is called Forbes and Deimos is named Deimos, which is the name of the son of Ares, the ancient Greek god of war.

"These two natural satellites are really small, but they are better than nothing."

Thinking about it, Chen Yuan used his spiritual consciousness to approach the two satellites, controlled the speed and merged into the orbit of Phobos, approaching Phobos.

"Swallow."

Phobos turned into golden light and submerged into Chen Yuan's body.

Chen Yuan's size increased slightly.

"Although the increase in size is not obvious, it has increased. This is good."

Thinking of this, Chen Yuan's eyes fell on Deimos next to him, and he controlled his consciousness to get closer to Deimos.

Devour Deimos as well.

All of a sudden, Mars became the polished commander.

Chen Yuan glanced at the spark in front of him.

"In this way, Mercury has been devoured, and Mars' satellites have also been devoured. What's next?"

Chen Yuan looked at Jupiter not far away.

Jupiter is surrounded by satellites one after another, and those natural Jupiter satellites are still orbiting Jupiter.

Jupiter itself has the most natural satellites among the eight planets in the solar system. Chen Yuan swallowed several of them before, but now there are still many satellites around Jupiter. The two satellites that attracted Chen Yuan's attention the most.

Those two satellites are very huge. One of them is slightly larger and the other is slightly smaller. It seems that the difference is not that big.

Although they are satellites, these two moons are actually much larger than Mercury.

These two moons are Ganymede and Callisto respectively. Ganymede is slightly larger than Callisto, which is not obvious when viewed from the earth. Ganymede is the largest moon in the solar system, larger than the planet Mercury.

Chen Yuan had seen these two satellites before, but their size and mass were too small at the time to swallow them.

But now, after devouring Mercury, Chen Yuan's size and mass are slightly larger than those two satellites.

"Now is the perfect time to devour them."

Thinking about it, Chen Yuan used his spiritual consciousness to control his already huge body and flew towards Jupiter.

As soon as he got close to Jupiter, Chen Yuan felt the strong gravity of Jupiter.

As for the spiritual consciousness that Chen Yuan now possesses, he can already use his speed to offset the gravity of the sun, let alone Jupiter, which has a mass smaller than the sun.

Chen Yuan used his spiritual consciousness to control his body, merge into the orbit of Callisto, and then control his speed to approach Callisto.

From such a close distance, Chen Yuan could see the appearance of Callisto.

Callisto, also known as Himalia, is one of the largest moons in the solar system.

In the past, Callisto was also called the 'Second Earth'.

Because people have discovered through detectors that Callisto has an atmosphere. Satellites with atmospheres are very rare. At the same time, it also has liquid methane.

Chen Yuan saw Callisto at this moment. He could see some liquid flowing on Callisto, which looked like a river, permeating the surface of Callisto.

That liquid is not water, but methane.

That's a river made of liquid methane.

This is rare.

However, because Callisto does not have a magnetic field. In the solar system, there is a lot of radiation.

If life is exposed to radiation, it will die.

The magnetic field can act as a barrier to block external radiation, thereby protecting the development of life.

But Callisto has no magnetic field, so it cannot become a second Earth.

"Is this a river made of methane?" Chen Yuan's eyebrows slightly stretched and he said, "It's really special."

"But, it's not important." Chen Yuan said: "Since you can't give birth to life, then let me devour you.

After Chen Yuan approached Ganymede, he controlled his speed, slowed down, and then approached little by little until his body touched Ganymede.

Approaching at almost the same speed, there was a little friction, but it was not a big deal.

"Swallow!"

Ganymede turned into golden light and sank into Chen Yuan's body little by little.

Chen Yuan's size and mass also increased.

"Comfortable!"

The next target is Ganymede.

Chen Yuan's eyes fell on Ganymede, and he controlled his body to approach Ganymede.

Merged into Ganymede's orbit and continued to approach Ganymede.

Ganymede can be said to be the largest satellite in the solar system, and it is also a satellite with a strong magnetic field.

From this angle, Chen Yuan can see Ganymede.

Ganymede's appearance is blue-green and some brown-brown.

Those brown-brown colors look like craters, and those bright blue-green locations are all made of ice.

Ganymede looks like a polar world covered by ice.

The Ganymede in front of him is somewhat similar to the current Earth, of course, the Earth does not have so many craters.

"Such a large satellite, this should be Ganymede." Chen Yuan had been exposed to astronomy before, and knew that there was a largest satellite Ganymede orbiting Jupiter.

"I heard that under the ice layer of Ganymede, there is an ocean. I wonder if it is true. I will try it."

Chen Yuan thought, and he controlled his body to get closer to Ganymede.

At a slightly faster speed, he hit Ganymede.

At the moment of contact, the ice layer on the surface of Ganymede was directly shattered by Chen Yuan's body.

At this time, the liquid gushed out from the broken place due to the impact.

Seeing the liquid, Chen Yuan's "eyes" lit up slightly.

Is that water?

Is there really water in the ice layer of Ganymede? !
