Do you know the mystery of day and night at poles?

Do you know the mystery of day and night at poles?  Are you living near the Earth's pole? If no, then you may not know the mystery at the poles. have you ever experience a day of 20 hours or a night of 20 hours? yes, it happens near the south and north pole. Astronomically we call it Midnight sun in which the sun appears all the time at the sky for 6 months and then the darkness of night grab that region for 6 months. What is Midnight sun? What are polar day and polar night? The midnight sun is when at least a part of the Sun's disk is visible above the horizon 24 hours of the day. The scientific name for midnight Sun is polar day and the opposite is the polar night .  As the upper edge of the solar disc disappears below the horizon, the Sun has set, and there is no longer midnight Sun. The moment the solar disc again becomes visible above the horizon, it is sunrise. In the Northern Hemisphere, the midnight Sun starts on the North Pole as the Sun rises ...

Do you know the myth about shooting stars?

Do you know the myth about shooting stars? Most of us probably have seen or heard about shooting stars. But no one wonders if it is actually a shooting or dying star or something else about which many of us have a misconception. If you think like everybody else about shooting stars so you are totally wrong.  So what exactly it is? A shooting star is not a star but a meteor. A meteor is the flash of light that we see in the night sky when a small chunk of interplanetary debris (space junk) burns up as it passes through our atmosphere. "Meteor" refers to the flash of light caused by the debris, not the debris itself. The debris is called a meteoroid. A meteoroid is a piece of interplanetary matter that is smaller than a kilometer and frequently only millimeters in size. Most meteoroids that enter the Earth's atmosphere are so small that they vaporize completely and never reach the planet's surface. What if shooting star reaches the Earth? If any part of...

Are you curious about the up-sky heaven?

Are you curious about the up-sky heaven? The star-lit sky is one of nature's most amazing displays that most of us have taken for granted. We have become very busy in our lives that we usually have no time to look at the heavens above us,  neither we are curious about up-sky heaven. We are already dead tired at the end of the day. In addition, most of us live in urban areas where the city lights have outshined the stars and only those in the countryside have the advantage of crystal clear view of the spectacular show. Some people have been inspired by these cosmic phenomena to either start a career in astronomy or engage in a hobby. Astronomers, physicists, and other scientists have begun their quest for space exploration by just looking at the stars in the night sky. They have a never-ending curiosity on how the solar system, stars, and other foreign bodies came into being. Their efforts have given us the knowledge of how the universe as a whole gave way to our own ...

Learn a Little More About Astronomy

Learn a Little More About Astronomy Astronomy is one of the most interesting subjects. The world of planets and stars is certain to leave anyone amused. Although man has been studying astronomy for several years now, there are still a lot of facts about the subject that remains relatively unknown. Let us take a look at some of them. One of the most surprising facts about astronomy is that you cannot see everything around. As per scientists, we can only see 5% of the matter that is around us. The rest of the matter is made up of invisible matter, which is also called dark matter. We know that the Sun is the prime source of energy of our planet. But, we are completely unaware of the fact that its center generates energy in huge 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 closest to the sun must have rising temperatures. However, quite surprisingly, the temperature of this planet co...
