What's wrong with Mars found 'human leg bone'? Is it a fossil of life? Scientist gives an explanation

There is a 500-meter-caliber-caliber-caliber-caliber spherical spherical radio telescope (Five-Hundred-Meter Aperture SPHERICAL Telescope) in Zhengnanbus, Guizhou, China, referred to as Fast. In the eyes of the famous British physicist Steve Hawking, he believes that our "China Eye" is too large, and it is easy to be captured by alien life and "visit" the earth.

So he repeatedly warned: Do not respond to any signal from outer space, because the other party's intention is unknown, and do not take the initiative to contact them. If this is exposed to the location of human beings, the two different levels of civilization will meet. An unimaginable catastrophe.

However, this has not reduced our enthusiasm for the exploration of alien life, but has become more keen on this matter in recent years. For alien life, Mars has signs of life. It has always been a highly debated issue. Scientists have launched dozens of cosmic detectors to Mars before and after. From the images returned by these detectors, we found some of Mars some of Mars. secret.

On August 14, 2014, the "Curiosity" Mars probe returned a image. A strange shape of stones appeared in this image. Some netizens said that they looked like human leg bones. As soon as this news came out, it caused a great uproar. Does Mars really exist?

A spokesman for NASA in the United States explained that he said that the reason why this stone looks like a human thigh bone is because it is caused by the weathering of Mars or water erosion, and it is formed by natural factors. Moreover, even if there is life on the surface of Mars, it may only be a simple and small creature like microorganisms.

We all know that although Mars is also shrouded in the atmosphere, the main component of the Mars atmosphere is carbon dioxide, followed by nitrogen and crickets. In addition, there are a small amount of oxygen and water vapor. There is no enough oxygen here to support the formation of complex life, so this is not possible to be biological fossils.

The sharp -eyed partner must have discovered that the word "water erosion", yes, on July 25, 2018, scientists found a liquid water lake with a diameter of about 20 kilometers under the Mars Antarctic Ice Covers. Essence But at present, it is only the result of radar analysis. In the later period, it must be verified after logging in to Mars, but the 1.5 -kilometer thick ice cover does not mean that it can be digged by digging. This is also very difficult.

The words are homely, although NASA came out to explain, but some people still believe that this is the true evidence of alien life, perhaps "don't hit the south wall without looking back". In this regard, some people put forward a special idea. He wanted to borrow the "Curiosity" Mars car from NASA to find Mars life, and also said that if NASA is willing to lend him the "curiosity", he guarantees Can find signs of life within a few months.
