The second planet is a black gas planet, this planet is even darker than the coal on Earth, this is because the temperature of this gas planet is too high, this is because the gas planet is too close to the star, plus the planet is huge, the atmosphere contains a lot of light-absorbing metal sodium, and gaseous titanium trioxide and so on.

It is the presence of these gaseous light-absorbing metals that has caused the planet to become what it is today.

After the probe's detection, the temperature of this planet has reached more than 1,100 degrees, such a temperature of 1140 degrees Huang Jin, some very strange chemical reactions that occur in the atmosphere of this huge gaseous planet.

Originally, the metals sodium, potassium and other substances are solid on the earth, but the temperature here is too high, so these metals have become gaseous, and these gases, such as gaseous sodium, have extremely strong light absorption, so they have a strange black appearance.

Of course, this absorbance was limited to a few color ranges, but the distance from the star and the high temperature of this huge gas planet led to an expansion of the absorbable spectral range, and this light-absorbing performance was extended to the full wavelength range of visible light, so the planet looked extremely dark.

The fourth planet is a planet similar to Venus, but because the brightness of the stars in this galaxy is much brighter than the sun in the solar system, the temperature on this planet is also very high, reaching a temperature of nearly 400 degrees, so it is impossible to give birth to life in such an environment.

The fourth planet is just in the habitable zone, with a sizable portion of the planet pale green and clouds floating in the sky.

Looking at this planet from space, it is clear that the ocean area of the entire planet accounts for about 70% of the total area, and the rest is occupied by three huge landmasses, and the three huge landmasses are not completely separated, there are several places between the three continents connected by slender land, and the land is full of dense primeval forests, of course, there will be some deserts and grasslands in the interior.

However, compared to the deserts of the earth, the deserts and grasslands on this planet are quite small, and there are also various shrubs on these grasslands and deserts, and countless dinosaur-like huge creatures live happily between the grasslands and forests in groups.

Obviously, although this planet is a living planet, it is not enough to evolve intelligent life, let alone develop civilization, due to the short life span of its birth.

And this planet is different from the earth, this planet has these three moons, one of which is very large, and the volume is even more than three times larger than the earth's moon moon, which can be said to be not much smaller than his mother star, and this satellite not only has liquid water, but also the content of liquid water is very sufficient, and the whole satellite can be said to be completely covered by the ocean.

However, there are also several pieces of land, of course, compared to the land of the satellite's home star, the land on this satellite is very small, the largest of which is only about the same size as Australia on the earth, and the smallest of them is not as large as the island of Taiwan. Therefore, the possibility of the birth of life on this planet cannot be ruled out.

The second moon is much smaller, not even half the size of the moon, this moon is earthy yellow, and this moon has a small ring, this moon is a planet, there is no water on it, and the moon is full of countless craters.

The last moon is about the same size as the moon on Earth, but this moon has no atmosphere like the second one, because its size and gravity are not enough to allow it to have an atmosphere, and there is no water on this planet, but this planet is very bright, even much more than the moon on Earth, and this planet does not have its own brilliance like the second moon. After all, in a planetary system, a satellite has its own method, which is very rare in the entire universe.

So it is very rare to have a ring that a satellite can have, and you don't have to think about having a second one, but there is one thing that the second satellite is very similar to the third satellite, that is, this satellite is also the same as the second one, with countless craters, the largest of which is very large, accounting for almost 1/4 of the size of the entire planet, you can imagine how huge the asteroid that hit this satellite was.

The four brothers of the Zhang family even had a hunch that the halo on the second satellite was actually the debris that was hit on the third satellite, and even the second satellite itself might be transmitted from the third satellite.

However, it is precisely the hesitation that has the third moon to block it, so that there is the possibility of life on his home planet, after all, if such a powerful impact really hits the life planet, then the creatures on this life planet do not know how many times they have perished, just look at the huge crater on its third moon.

After discovering this planet of life, the four brothers of the Zhang family were very excited, this is the first planetary system with life discovered since their team set off, so this planet will be owned by them, in addition to the mother star of this planet has life, the possibility of life on his first satellite is also very large, this planet has the existence of liquid water necessary for life, and this planet is close enough to the sun, so the value of this planet and his first satellite is very large.

If there is really life on his first moon, then this is also the first planet and moon that have been discovered by mankind in history, which will be of great help to mankind's understanding of the universe.

After discovering this living planet, the four spaceships led by the four brothers of the Zhang family couldn't wait to fly like this star, and the probes they released continued to transmit data back to the planet, even the first satellite.

But when their spacecraft arrived in space near the main planet, the probe's exploration of the atmosphere on the planet was basically over, and the content of atmospheric matter on this planet was very similar to that of the earth, but the oxygen content was slightly higher than that of the earth, which can also explain why the size of life on this planet is so large.

And even greater good news has also come back, the atmospheric gas content on this planet is very close to that of the earth, human beings can live freely on it without love, and the aura content on this planet is also very sufficient.

In addition to this, they also found the presence of life on the first moon of the planet.
