As you can see from the picture, there is a black thing on the surface of Pluto, which looks like a "snail". This thing will move. Is this life on Pluto?
Scientists at NASA deny that this is alien life. First of all, on the scale of this photo, the size of the "snail" has reached several kilometers, which is similar to the size of a hill. This is obviously not life. So, what is this moving thing?
Analysis shows that the "snail" on Pluto is actually a nitrogen-fixing iceberg floating on the ice. Because the solar radiation received by Pluto is very limited, its surface temperature is extremely low, only about MINUS 230 degrees Celsius. At such a low temperature, nitrogen molecules, carbon monoxide, methane and water on Pluto will condense into solids and form the surface of Pluto with rocks.
Inside Pluto, due to the heat generated by geological activities and the decay of radioactive elements, an underground liquid water ocean with a depth of more than 100 km may be formed below Pluto's frozen surface. Because the upper layer of the underground ocean will freeze when it is cold, it will break some parts of the surface and drive the nitrogen-fixing iceberg on the surface to move. As for why the iceberg appears black, it is because the iceberg is mixed with impurities, just like a dirty snowball.
Seeing this title, I suddenly have an impulse to hit someone.
It's just a snail of Pluto. What are you making a fuss about? I'll give you enough controversy at once.
Humans are a curious race, and we have grown up recently. For decades, it seems that we can see other planets in the solar system at will by launching detectors and using astronomical telescopes. It's not that we saw something unusual at once!
There are pictures and truth. The first, of course, is the controversial Pluto snail:
This was discovered by accident in a large number of photos of Pluto sent back to Earth by the New Horizon probe. At first glance, it is really a vivid snail!
Don't worry, snails are nothing, and we still have Okumo on Mars!
Of course, this is also a masterpiece of NASA! Can these satisfy the curious people's obsession with alien life? How naive! We still have Jupiter dolphins!
Pay attention to the red circle in the picture! A dolphin is driving waves in Jupiter's nitrogen-filled atmosphere, making a huge noise!
I quite agree with the saying circulating on the Internet that "the beginning of a picture depends entirely on compilation"! This spider, dolphin, snail, it is in line with this classic comment on writing.
Mars spider is only the result of sublimation of dry ice on the surface of Mars, Jupiter dolphin is just a storm with just the right shape, and this Pluto spider is just a huge ice cube, which looks a little dark due to the angle of light refraction and slides on solid nitrogen.
This discovery was explained as early as 20 15 when NASA released photos. I don't know why I put a scary title to prevent innocent people from eating melons.
In the solar system, life on the earth is absolutely huge and used to it, but on other planets or stars, human beings have not found any traces of life so far. According to scientists' reliable analysis and estimation, Titan is most likely to have life.
Titan is the largest satellite orbiting Saturn, with a diameter of 4,828 kilometers, much larger than Pluto and similar to Mercury. Its mass is 1.8 times that of the moon, its average density is 1.9 grams per cubic centimeter, which is about 1/3 of that of the earth, and its gravity is 10% of that of the earth. Crucially, Titan is covered with a thick methane atmosphere.
Titan has a sea of liquid methane on its surface, which is very similar to the early earth where life evolved. Although the surface temperature of Titan is extremely low, it is difficult for carbon-based organisms to survive, but Titan may have other life forms such as silicon-based organisms.
These are not our guesses, but the real shooting and analysis results of the detector Huygens. This is not a situation made up by the wings of imagination.
I'm Mr. Cat. Thanks for reading.
Although scientists are eager to capture life, it is a pity that the photos taken by Pluto do not belong to life, but are just huge movable icebergs.
Pluto is too far away from the earth, and there is little sunshine left when it arrives here. So it is extremely cold on Pluto, and both nitrogen and methane are frozen into ice. Therefore, no life can naturally live on the surface of Pluto. Anyway, any living thing on earth will turn into ice when it arrives at Pluto. Just like the "uncle" in the wandering earth, it freezes instantly.
In addition, the photo taken by Pluto probe, this snail-like object, is actually huge on earth. Because the detector is a photo taken above Pluto's orbit, the small celestial body in the photo is actually huge. In the extreme environment of Pluto, it is simply not enough to support such a huge life.
Scientists have analyzed what this so-called snail is. It's just a moving iceberg. Although Pluto is frozen on the surface, it is still very active inside. So it will lead to some geological movements and make some icebergs look like moving snails.
Thank you for your concern! Before answering this question, let's learn some basic information about Pluto.
1, Pluto's past life
1 Feb. 8, 930 18, American astronomer Clyde clyde william tombaugh successfully found a celestial body with an average distance of about 5.9 billion kilometers from the sun in a pile of photos he took according to the predictions of astronomers Lowell and Pickering, and officially in May1of the same year.
However, the good times did not last long. With the development of science and technology and the deepening understanding of the solar system, Pluto observed by people is actually smaller in size and mass than the moon, the satellite of the earth. Its orbit is not only very eccentric, but also very eccentric. Because its apohelion is 7.4 billion kilometers and perihelion is 4.4 billion kilometers, it sometimes runs inside Neptune, a wonderful celestial body, and becomes a heterogeneous planet. Because it doesn't meet the definition of a planet, its mass is large enough to be adjacent.
2. The current situation of Pluto
Pluto is about 2370 kilometers in diameter. Through calculation, it is not difficult to find that its volume is about 696664 1070 cubic kilometers, which is about1156 of the earth. Because it is far away from the sun, there are about 39 astronomical units, so even sunlight takes about 5.46 hours to reach, so that the surface temperature of Pluto is as low as -229℃. Even methane, nitrogen and carbon monoxide in Pluto's atmosphere will condense into "ice" at such a low temperature. Pluto's heart is actually a nitrogen ice.
And Pluto revolves around the sun and rotates at the same time. Its period of revolution is about 248. 1 year, and its rotation period is about 6.38 days. This shows that because Pluto's rotation period is relatively slow, although the surface temperature difference is relatively small when it is far away from the sun (the sun is only a bright star from Pluto), there is still a certain difference between the ambient temperature of dark day and dark night, and the estimated temperature difference is 65438.
3. What is the snail on the surface of Pluto?
On July, 2065438+05 14, New Horizon flew over Pluto. This probe was launched by NASA in 2006. It took nearly 10 years to send new horizons to Pluto. Its main task is to detect Pluto and its largest satellite, Ka Rong (Phobos), and to detect asteroids in the Kuiper Belt.
Although New Horizon is the nearest unmanned probe to fly over Pluto, its distance from Pluto's surface is about 1100km longer than the earth's diameter. New Horizon uses the long-distance detection imager LORRI, and its accuracy is about100 *100m, which is basically the same as1football field. Obviously, it was taken like this.
In fact, the "snail" mentioned here is only nitrogen ice on the surface of Pluto. It is formed because it receives less solar radiation and its temperature is extremely low, which has nothing to do with alien life.
Welcome to comment on the above content!
It's not surprising that the detector photographed a small snail on another planet. As long as you like, you can find any animal in the photos taken by NASA. Scientists don't like the theme of these questions, and every day they shoot something a bit like it.
The picture above shows this so-called snail, which may be an iceberg on Pluto or something. If this is alien life, it's more like alien booger. And judging from the photos taken by the planetary probe, the scale of this thing will be amazing, far from being explained by a snail.
In fact, the snail on it doesn't look terrible, but Okumo photographed by NASA at the South Pole of Mars is even more terrible. This spider-shaped ground looks like a spider with long legs. Actually, it has nothing to do with extraterrestrial life. Whenever the temperature in the polar regions of Mars rises, underground carbon dioxide gathers and ejects, which is a landform change caused by sublimation of dry ice in the polar regions of Mars.
With the existence of PS, the era of seeing is believing has long passed, and any discovery needs to consider all kinds of evidence comprehensively, not to mention these are just things that look like. Please look at the picture above. I accidentally photographed a Godzilla, so is the world going to start a monster war?
I'll go. This must be a kind of life. Judging from the distance taken at that time, this snail is at least several kilometers long. It's the first time I've seen such a big snail.
We can't just say what it looks like If the cloud in the sky looks like a UFO, we can't say it is an alien spaceship. We must understand this basic truth.
Speaking of a snail on Pluto, what is it?
What is this? It's just a mixture of ice and water, floating on the surface of high-density solid nitrogen and moving back and forth. People who don't know the truth think it's a big snail? Hee hee.
Moreover, this issue is still "controversial among scientists." Don't label scientists. Scientists have never disputed this question. Just like Lu Xun's famous saying, most of them are your own, haha.
Scientists have been arguing about a "snail" photographed by NASA Bruto. Is it alien life?
Is there life on Pluto? Let's take a look at the surface temperatures of various celestial bodies in the solar system, and we can also get a general idea of whether there is life!
You must find that there is no temperature of Pluto on it, because it is the surface temperature of the eight planets, and Pluto has been kicked out of the ranks of the eight planets, but for reference, Pluto's perihelion is around Neptune's orbit, which means that the highest temperature on Pluto is similar to Neptune's!
First, there must be no life at low temperature?
Not exactly. For example, the extreme low temperature of the earth's north and south poles can reach -60℃-80℃, but the north and south poles are still active areas of life, but I regret to inform you that the north and south poles are connected with the warm ocean of the earth, so the low temperature of the north and south poles is an adaptation process, but it is not a necessary option for the birth of life!
Second, can low temperature breed life?
The map of Titan's surface, of course, the radar data of Cassini's leap is incomplete, so they are all strip areas, which can make do!
3. Why are there moving objects on the surface of Pluto?
Only when there is life can it move? Perhaps this is the biggest misunderstanding! Many functions of nature can cause a feeling of moving. Weathering on the earth is one of the functions. Of course, life on earth is rich and colorful, and these phenomena are rarely taken seriously, but Pluto has moving objects, which really scares everyone! This shows that Pluto's cold surface is not dead, but there will be some activity!
From this photo, it really looks like a moving snail, leaving traces of movement behind it, but in proportion, this snail is not ordinary! Of course, scientists also explained why this happened!
1, the nitrogen in Pluto's atmosphere has been frozen.
2. The density of nitrogen ice is higher than water ice.
These two points are the main key points that cause the object to move, because nitrogen ice melts and water ice becomes lubricant, and Pluto's surface is not Ma Pingchuan, and there is altitude, so sliding becomes an inevitable option! Why does nitrogen ice melt? Because Pluto's surface is extremely cold, but its heart is still hot, it is also very common to exchange heat with the surface!
How does the motion of objects on Pluto's surface come from? Do you have the urge to hit people? I want to build a spaceship. You showed it to me?
First of all, NASA did photograph a snail-like object on Pluto. Secondly, from the comparison of the details of several photos, there is no doubt that this object is indeed moving. So is this moving object an alien life? Let's take our time.
Pluto was once one of the nine planets in the solar system. In 2006, Pluto was expelled from the ranks of planets because of its mass and orbit and became a dwarf planet. Compared with our moon, Pluto has only one sixth of its mass and one third of its volume. Pluto's perihelion is 4.4 billion kilometers and its apogee is 7.4 billion kilometers. Because of the distance, it is much more difficult to detect Pluto.
Certainly not alien life. The so-called "snail" is just a rumor.
On July 4, 2065438/KLOC-0, the probe "New Horizon" flew over Pluto and took many precious photos. These photos can help people know more about Pluto. However, this photo has become the object of media freedom, because there are some strange-looking things in these photos. The media began to make a frenzy, and some said it was alien life and giant snails.
Later, NASA personally came out to refute the rumor. What the hell is this?
Actually: methane iceberg.
In fact, there are many similar methane icebergs on Pluto. So this is just a very typical rumor.
In fact, it should be said that the probability is extremely low and almost impossible. This is because the surface temperature of Pluto is only about -2 10℃, so it actually feels more like a big snowball. The surface is mainly composed of a large amount of solid nitrogen and a small amount of methane and carbon monoxide. There is a lot of solid methane on the side facing its satellite.
Under such extreme conditions, it is impossible for living things to survive, let alone produce alien civilization.
There are actually many rumors about alien civilization. I hope there will be an alien civilization every time the photos of the detector are sent back. The moon, like Venus, is often called the object of rumors, such as Venus having pyramids and so on.
In fact, however, all these news proved to be rumors in the end. So, just read these reports, there is no need to take them seriously.
NASA photographed a snail on Pluto. Scientists have been arguing about this snail. Some people think it is life on Pluto.
As we all know, in the solar system, the earth is just an ordinary planet, but it also has its own special features, that is, there is life on the earth, and no traces of life have been found on other planets. Pluto is a planet outside the solar system. At first, people thought it was a planet, but later it was found that its orbit was not fixed, so it was excluded from the planet and downgraded to a dwarf planet.
People may be too lonely to stay on the earth, so they have been exploring the traces of alien life. Our earth is small and ordinary, even insignificant in the universe. The more people understand the position of the earth in the universe, the more they want to discover alien civilizations. This desire can be said to be stronger every day. So whenever people find something suspicious, it is easy to regard it as alien life.
It is said that there are alien bases on the moon and Martians on Mars. Now it is said that there is a snail-like object on Pluto, which is most likely the ironclad evidence of life on Pluto. In 2006 1 month, the United States launched the "New Horizon", and scientists entrusted it with the heavy responsibility, hoping to discover alien life through it, or hope to be discovered by alien life.
