I bet many of you must have dreamt of getting into the outer space and witness asteroids and meteors. Many things have added to your curiosity and hence made you eager to explore more about space. But sadly enough, most of our space-related knowledge has been built up through some of the Hollywood movies or irrelevant internet blogs that are very far from the reality a majority of times.
But in the interest of setting things clear in front of you, here we dispel a few myths about the space.
The distance of a planet from the sun does not affect the average temperature on the planet. Talking about Mercury, yes, it is indeed the closest planet to the sun but it doesn’t mean that it is the hottest one.During the day, the temperature of the surface of Mercury can reach up to 420 degrees centigrade. The hottest planet in the solar system is Venus and the average temperature on the planet does not go below 462 degrees centigrade.
The moon rotates on its axis just like Earth does. Amazingly, both the moon and Earth rotate at the same time, meaning only one side of the moon is visible here on Earth. But just like Earth, both of the moon’s sides get an equal amount of sunlight.Venus may look like Earth in pictures, but the planets are not the same at all.The atmosphere on Venus is a dense carbon dioxide that makes the planet extremely hot, and it has clouds of sulfuric acid floating around that makes taking pictures of its surface impossible.
We have all known that Sun is yellow-orange or reddish in color depending upon the time of the day and its position. But sun is actually white. The color of any light depends on the temperature.
But why have we been considering it as yellow then? Actually, the thing is, the longer light waves from the yellow-red part of the spectrum, cross the atmosphere of the earth without loss and the shorter greens of violent waves diffract a lot.
And this is the very reason why the sky appears blue during the day and black during the night.
We know from a number of Hollywood movies that if we remove our helmet in the space, our head will swell and blow up. No doubt that it is deadly, but death will not arrive you as immediate and as horrible as it is known.Actually, the exceedingly low outside pressure is extremely dangerous for the lungs, heart, and the brain and apparently it is not the most pleasant way to die.
The Sun is not burning but glowing because the heat generated by it is the result of a nuclear reaction and not a chemical one.
