Astronomy is one of the most fascinating. The world of planets and stars is safe, you can entertain anyone. Though man has studied astronomy for several years, there are many facts about the topic that remains relatively unknown. Let’s take a look at some of them.

One of the most surprising about astronomy is that you can not see around it. According to scientists, we can not see 5% of the material that surrounds us. The rest of the material consists of invisible matter, the dark matter as well. This is comparable to a high cholesterol level. They are available in the body but can not see until you walk a cholesterol test.

We know that Sun is the primary energy of our planet. But we are completely unaware that the heart generates energy in large quantities every second, which is equal to the combined energy of billions of atomic bombs.

It is very likely that the planet Mercury, which must be closer to the rising temperatures in the sun. However, quite surprisingly, the temperature of the planet could easily drop to -280 degrees F. Such a drastic drop in temperature, the fact that Mercury has no atmosphere, making it impossible for the planet, all the heat from the sun will be attributed to trap . No wonder the face of this planet from the sun is cooler.

In contrast, Venus is relatively far away from the sun is warmer. This is simply because the atmosphere of Venus is much thicker, which traps heat. As a result, Venus has a tendency to be warmer.

When we asked about the inventor of the telescope, we always credit to Galileo Galilei. But the fact is that Galileo used the tool to study the first stars. Historians and researchers believe it is the invention of John Lippershey, a Dutch spectacles maker. You can also try using the telescope to several celestial bodies, including the Moon observed.

Shooting stars we see in the sky are just dirt. When comets pass through the Earth’s environment, they leave a trail of dust behind them. If the particle moves in the environment, they heat up. This creates streaks of light in the sky which appears like a shooting star.
