A natural phenomenon is a non-artificial event in the physical sense, and therefore not produced by humans, although it may affect humans. Common examples of natural phenomena include volcanic eruptions , weather, and decay. Most natural phenomena, such as rain, are relatively harmless so far as humans are concerned. There are various types of natural phenomena, which include Meteorological phenomena, weather, including hurricanes, thunderstorms and tornadoes, and geological phenomena, including volcanic activity and earthquakes. So here I have compiled some of the most fascinating natural phenomena. Also check out some Alien looking landscapes on earth HERE .

The universe can be a very strange place. While groundbreaking ideas such as quantum theory, relativity and even the Earth going around the Sun might be commonly accepted now, science still continues to show that the universe contains things you might find it difficult to believe, and even more difficult to get your head around. Theoretically, the lowest temperature that can be achieved is absolute zero, exactly ?273.15°C, where the motion of all particles stops completely. However, you can never actually cool something to this temperature because, in quantum mechanics, every particle has a minimum energy, called “zero-point energy,” which you cannot get below.
