Antarctica is the last continent reached by humans, also called the "Seventh Continent". It is located at the southernmost point of the earth, almost all of the land is within the Antarctic Circle, and is surrounded by the Pacific, Indian and Atlantic Oceans. It is the continent with the highest geographical latitude in the world and the continent with the most longitudes. The total area is about 14 million square kilometers, accounting for about 9.4% of the world's total land area, ranking fifth among the seven continents. But in this inaccessible and mysterious continent, there are too many puzzling mysteries!

1, The Mystery of Hot Water Lake in Antarctica

Antarctica is the last continent reached by humans, also known as the

Hot Water Lake is an "oasis" located in the Antarctic Ice Sheet (2% of the South Pole is not covered with ice and snow all year round) Land), this lake was first discovered by Americans. At that time, American space satellites discovered this huge "lake" that humans had never seen before in the Weddell Sea on the coast of Antarctica in the southern Atlantic Ocean. It is visible most of the winter, but sometimes fades in and out, making its presence easy to miss with satellite imagery.

What is interesting is that in the 1960s, Japanese scholars conducted a detailed analysis of the water temperature and substances contained in Lake Vanda through measurement data. He found that the water temperature under the thin ice layer of Lake Vanda was about 0°C, but as the depth increased, , the water temperature will continue to increase until it rises to about 7.7°C at a depth of 15 to 16 meters. Below 40 meters, the extent of the increase in water temperature will gradually decrease. However, at 50 meters, the extent of the increase in water temperature will decrease. It suddenly intensified. Strangely, the water temperature at the bottom of the lake at 58.8 meters was as high as 25°C, which is almost the same as the summer surface water temperature in the East China Sea. It is surprising that there is such a hot water lake in the cold Antarctic continent. .

Scientists found that there are neither active volcanoes nor hot springs at the bottom of the lake. Moreover, the temperature of the sediment at the bottom of the lake is lower than the temperature of the water layer at the bottom of the lake. Therefore, it can be concluded that the heat source does not come from underground.

2. The Mystery of the Ice-Free Lake in Antarctica

Antarctica is the last continent reached by humans, also known as the

From the photos taken many times by the artificial earth satellite between 1974 and 1976, scientists discovered that in the ice world of Antarctica, there is an ice-free lake with an area of ​​about 483,600 square kilometers. lake. The lake disappears and appears. In 1981, the former Soviet Union and the United States sent a 26-member Antarctic expedition team.

They searched according to the location of the lake shown in the artificial satellite photos, but could not find it. The team members only found numerous air bubbles with higher temperatures in the unfrozen lake waters.

Some scientists even believe that there is most likely a secret base built by aliens under the ice in Antarctica. The heat energy emitted by them in their activities melts the ice here. Some scientists pointed out: This is a warm water lake. It is very likely that there is a large hot spring under the water that raises the water temperature here and melts the ice.

There are many different views on this question, and there is currently no very convincing answer.

3, Antarctica The Mystery of UFOs The Mystery of UFOs

Antarctica is undoubtedly the place where UFOs appear most frequently. Scientific expedition bases set up in Antarctica around the world have recorded multiple UFO sighting reports.

A dozen years ago, a strange object with a circumference of about 150 miles (240 kilometers) and a depth of 85 meters was discovered in Antarctica. But because it is still an unsolved mystery, it always leads to various speculations.

It is said that on June 10, 2004, a large number of UFO fleets suddenly appeared in the sky over the Southern Ocean , and then flew north to the vicinity of Guadalajara, Mexico, which is only 1,600 kilometers away from the US border.

At that time, the U.S. military immediately entered the highest alert, but before reaching the U.S. border, the UFO fleet quickly returned to their base in the Southern Ocean.

In addition, scientists from Antarctic scientific research stations in Russia, Australia and other countries have repeatedly discovered flying saucers flying towards the hinterland of Antarctica.

Especially at 21:00 on a certain day in 1979, a cigar-shaped long flying saucer flew towards the hinterland of Antarctica. When it passed the Soviet Antarctic Scientific Research Station, it stayed in the sky for four or five minutes before flying away, as if it was on the ground. observe.

In addition, some pictures taken by satellites in recent years show that some saucer-shaped and UFO -shaped entrances were discovered in the high sea-climbing areas of Antarctica, which further validates the possibility of this speculation.

Until today, scientists do not know and have no way to accurately discover the origin and accurate information of these strange objects, and they are not sure that Antarctica is the base of these UFOs, but we believe that scientists will one day be able to crack the answer to this mystery.
