10 mysteries in the solar system that scientists still cannot explain (2)

Although the space science has made many new advances, with the support of advanced technology, there are still mysteries that we cannot explain. Not far away, but even in our solar system there are many mysteries.

The mysteries in the solar system

6. Dark spots on Venus

Venus has a dense atmosphere, covered by hot gases, making it impossible for scientists to observe its surface. They must use radar waves to pass through these hot clouds and collect reflected waves from which to model the surface of Venus, as well as calculate the distance from the ground to the atmosphere.

When NASA's Magellan spacecraft explored Venus and carried out this task 20 years ago, scientists discovered the mystery that could not be solved. These are black spots in radar waves that reflect from the surface of Venus, especially in areas of high altitude, the more black spots appear. On the other hand, the opposite of Earth is the high-altitude areas that must be reflected more clearly.

Scientists cannot observe what is on the surface of Venus, because the star's atmosphere is like a dense sandstorm. Scientists believe that this is heavy metal dust due to the erosion by storms that cause them to be swept into the atmosphere and still stuck there.

7. Bright blocks in Saturn's F belt

Saturn's F belt is the most unstable belt and it often changes, so the observation and study of this belt is quite difficult. One of the mysteries that scientists have not explained relates to the glowing blocks inside this belt .

While the other belts are composed of large sized stones, the F belt is composed of tiny ice particles like dust particles. However, sometimes these ice particles clump together and form giant ice cubes about the size of a mountain. And sometimes two flat mountains are formed and in the process of flying F-rings they collide with each other and cause a big explosion. However, it is only a theory of scientists.

8. The icy moon of Jupiter Europa

Scientists announced in 2013, that NASA 's Hubble telescope has discovered a sudden groundwater circuit erupting 200km on the surface of Europa, the moon of Jupiter. Suddenly hoping to find alien life opened, NASA launched a probe into the moon Europa to determine as well as explore life here.

However, the probe was launched without any sign of water here, even steam could not be found. NASA then searched the old data and made sure it was a sign of water, even a giant water column 200km high. This mystery has not been answered so far, because NASA has not been able to send the landing probe on the surface of the Moon , to study more thoroughly.

9. Methane gas on Mars

During the exploration of Mars, NASA scientists did not detect much methane in the atmosphere, but sometimes there was a sudden increase in methane here. Meanwhile, about 90% of the methane on Earth is produced by living organisms. So scientists are curious about where the Martian methane gas comes from.

There are many possibilities. One hypothesis is that the bacteria produced methane gas. Another theory is that a meteorite that contains a lot of carbon after hitting Mars has created an abundance of carbon that combines with hydrogen under the action of the Sun ultraviolet to produce methane gas.

The second mystery that scientists have not been able to explain, is why the methane gas on Mars does not appear often, but sometimes appears like a volcanic eruption. This caused scientists a headache, because after being created methane gas can exist stable for about 300 years.

10. Life on the planet Ceres

Ceres is a Texas-sized dwarf planet , NASA's next target for exploration in March. Unlike many other dwarf planets in our solar system , Ceres' surface is not only dry but also has a lot of ice. Scientists also predict that there may be an ocean underneath the ice on the surface.

According to the data collected, scientists estimate the amount of water accounted for 40% of the planet's mass. Outside of Earth, Ceres is the planet with the most water in our solar system.

While to survive life on a planet requires three most important elements: energy, water and basic chemicals like carbon . In addition to having water, Ceres is close enough to the Sun to receive energy from sunlight. And it only lacks the basic chemicals, but the meteorite collisions can compensate.

Therefore, scientists believe that the planet is like 90% of the Earth at the time of its formation. Since then, the study of Ceres will bring a lot of ideas to scientists, not only finding a place where humans can live in space, but it also helps explain the formation of life on Earth, helps us understand more about the origin of life.
