subject: Learn Some More About Astronomy [print this page] Gazing at the sky in the night and wondering at its expanse is what astronomers have been doing since thousands of years. But even now there are a few aspects of the universe that are beyond the imagination of the human brain. The more we tend to plunge deep into the secrets of astronomy, the more confused we get at the amazing ness of it. The celestial world which seems so quiet and gorgeous holds a rage inside and is full of multitudes of truths which we do not know or assume wrong. Checkout the few of these interesting and amazing facts.
It may appear very surprising to you, but it is impossible to see everything around you? According to studies, we are able to observe just 5% of matter that surrounds us. The rest is invisible and is known as the dark matter. This holds true for high cholesterol levels too. They're present in the body but are unidentifiable unless you go through a cholesterol screening test.
We know that Sun is the prime spring of energy of our planet. But, we are absolutely unaware of the fact that its core generates energy in great quantities every second which is equal to the energy of billions of nuclear bombs combined.
It is quite expected that the planet Mercury, being the nearest to the sun must have rising temperatures. However, quite surprisingly, the temperature of this planet could conveniently drop down to -280 degrees F. Such a drastic fall in temperature can be attributed to the fact that Mercury lacks atmosphere, which makes it impossible for the planet to trap any heat as coming from the sun. No wonder the face of this planet away from sun is colder.
On the contrary the planet Venus is comparatively hotter despite being distant from sun. Cause of the same being, the thick layer of atmosphere around Venus helps trap the heat from the sun, helping to raise the temperature significantly.
Quite surprisingly, the popular invention of telescope by Galileo Galilee might be somebody else s creation. Many researches have suggested that the actual inventor of telescope is Johannes Lippershey, a Dutch eyeglass maker by profession. Galileo was in fact the 1st one to use telescope. This device was invented to get a far better view of celestial objects like moon.
Not many are aware of the fact that the shooting stars are just basic dirt particles. Comets tend to leave a cluster of dust behind when they pass through the atmosphere of the earth. These particles in turn get heated up, when passing through the atmosphere. This results in streak of light which takes shape of a shooting star.
These are just some lesser known facts about the universe. Astronomy is in fact replete with such unknown facts that could amuse the mankind to no ends.
