Where is the coldest place in the universe?
In a good night sky, no matter which direction we look in the sky, we can see the dense stars, but this is only our illusion the distance between the stars in the universe is very large, how large? Let's put it this way, if we compare the sun star to a ping pong ball, then according to the proportion of conversion, even the closest to the sun another "ping pong ball" - Proxima, but also far away from 1000 km.

Is there a life form larger than a planet?
Among the many science fiction works, the visually stunning "interstellar beast" is one of the favorites. This subversive creature has the size of a planet and can shake several star systems on its own.

For 80 years, This World War II Shipwreck Leaked Toxic Pollutants into the Sea, Changing the Ecosystem
The year is 1942. The atmosphere is abuzz with the sounds of the Second World War. The German Navy took over a fishing trawler, V 1302 John Mahn, for use as a Vorpostenboot, or patrol boat, for Operation Cerberus, or Channel Dash, a German naval operation. Unfortunately, V 1302 John Mahn was the only German ship sunk by UK bombers during the entire Channel Dash. It has rested in the Belgian North Sea ever since.

11 cold knowledge about the blue whale
If you were asked to picture in your mind a 10-story tall animal walking down the street, you would probably think of Godzilla or King Kong. But if you were asked to imagine it as a marine mammal swimming...then you now have a blue whale in your mind.

Progress and Obstacles to Resurrecting Prehistoric Organisms
Recent advances in genetic engineering and cloning have led to the idea of "resurrecting" animals that have been extinct in the past, but how far can we go? Hendrik Poyner, director of the Centre for Ancient DNA at McMaster University in Canada, and his research team succeeded this year in extracting the complete genome of the mammoth, an ancient animal that only appears in science fiction movies, for the first time, and published a report on it in the semiannual journal Current Biology. Poyner is excited to have access to the complete biological data of the long-extinct mammoth. He said, "Research has progressed rapidly in the last 10 years. I was involved in the first phase of this research as a student, and now I'm working on the second phase. I feel like I've become an old man in this field, even though I'm only 44 years old."

Greek whale strands dead, humans are to blame
There are some very special creatures in the ocean, such as whales. Although we call them whales, they are not real fish. Unlike fish, whales are aquatic mammals. That said, whales are viviparous and breathe with lungs, and they need to surface frequently for air. Because whales are so large that they cannot survive in shallow waters, these whales can be life-threatening if they become stranded on the coast. For example, on April 19, 2022, a huge sperm whale was stranded on the coast in the waters of Xiangshan County, Ningbo. Because the sperm whale was over 19 meters long and weighed 70 tons, it was very difficult to rescue the sperm whale. Fortunately, with the efforts of rescuers, the sperm whale stranded on the coast finally returned to the sea safely.

Scientists discover mysterious 'yellow brick road' at the bottom of the Pacific Ocean
The universe has existed for more than 13 billion years, the earth has existed for more than 4 billion years, and the earth has nurtured life for more than 3 billion years, while we humans have only existed for a few million years. So some people think that before the emergence of humans, there may have been prehistoric civilizations on the earth. We cannot find these prehistoric civilizations now. It may be that they have been destroyed, or they may have achieved interstellar immigration and left the earth.

Mysterious islands in the South Pacific appear and disappear
There are many large and small islands on the earth, and some islands are far away from people and may not be known by too many people or visited by too many people. However, with the advancement of human technology, we do not necessarily have to visit the scene to see the islands far away from humans. With the help of various aircraft or satellites, we can actually get some pictures of the islands. Especially in front of high-resolution satellites, those islands can be said to be nowhere to hide. However, some situations are quite strange. Some islands appear on the satellite map, but when we go to the scene, we cannot find these islands. What is going on?

"Fireball" reappears in the American night sky?
I believe everyone still remembers that we have shared a topic before, that is, a roaring fireball appeared in the sky of the United States at about 8:00 a.m. on April 27, 2022. At first, scientists believed that the flying speed of this roaring fireball may reach an hourly speed. 55,000 miles, or 24,587 meters per second, which is at least twice the speed of Earth's second universe. Later, new research by scientists showed that the speed of the roaring fireball may not be as fast as previously predicted, about 35,000 miles per hour, or 15.6 kilometers per second. Although not as fast as predicted at the beginning, this speed is still quite astonishing, faster than the vast majority of human aircraft and spaceships.

NASA spacesuit leaks again, how dangerous is it? There have been astronauts who nearly drowned
In our impression, the United States seems to spend money "big", to complete the Apollo manned lunar landing program, almost all the country's efforts, huge human, material, and financial resources, and finally, in 1969 the first manned lunar landing was completed. After the manned lunar landing program, the United States also manufactured a reusable space shuttle. It seems that the financial strength of the United States, but sometimes also to repair, a device with decades, for example, the United States is now using the spacesuit has been more than 40 years.

How terrible is reproductive isolation in nature?
The history of life on Earth is 4 billion years old, and countless species have evolved during this long evolutionary history of life. Due to genetic mutation, chromosomal variation, and genetic recombination, the original life has been differentiated into various branches on the path of evolution, resulting in new species and gradually forming a variety of creatures.
