Moon is actually very dark with no light of own. It is basically a big mirror that reflects back the Sun’s light. It is the light of the Sun that makes it shine.
Do you know how far the Moon is from the Earth? The Moon is roughly 1.27 light…
No, Moon is not a star. Moon is not a big as a star should be. It is a natural satellite of the Planet Earth. A satellite is a small, round ball that revolves around a planet. As we now know, a star is a massive ball made of gases…
A light-year is a distance that the light travels in one year. So, if we read somewhere that a star is 4 light-years away, we know what it means right? It means that it will take 4 years for the light of that star to reach us.
Stars are billion of kilometres away from each other. Yes, that sounds like an awesome distance. Isn’t it? Since the stars are so far away, it takes a huge amount out time for the light of the star to reach us. Depending on the distance of the star from the Earth, the light of the star can take seconds, minutes and sometimes even years to reach us!
The name of the star nearest to the Earth is Proxima Centauri. Are you wondering how far it is from Earth? Well, it is 4.28 light-years away.
A star is a huge ball made of hot gases. The main gas in a star Is hydrogen. Thy hydrogen atoms are constantly bumping into each other with so much force that it makes the hydrogen burn. This reaction produces lots of heat and light, which makes the stat shine. When hydrogen atoms collide with each other give out this light, another gas called helium is also produced in the process. So, a star is basically made up of two main gases hydrogen and helium.
The stars are there in the sky both during the day and at night. During the day, the sun shines so brightly that we cannot see the other stars present in the sky. At night, when the Sun goes down and the sky is dark, the light of the stars can be seen. Have you noticed how starts start to appear as the Sun starts to set? Do you know that the Sun is also a star? It shines brighter than other stars as it very close to the Earth while the other stars are far away.
Actually, stars don’t twinkle at all. They only appear to twinkle. This is why it happens. The lights of the stars reach us by passing through the astomosphere of the Earth, which is made up of many layers of gases. These gases have different temperatures, pressures and several pockets of…
Imagine the sky lit with various colours in so many patterns! First green, then pink, red, orange and then turning into violet! All changing one after the other on their own!
The Northern Light, also known as auroras, are lights that naturally occur in the sky. They create amazing displays…
