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 sounds from the Earth. It means the light from the Moon. It takes 1.27 light seconds to reach us. Let’s see what this distance means if we travel by car. It would take approximately 130 days to reach the Moon by car but cars don’t go in space! If you, however, travel by rocket, it would take 13 hours to reach the Moon.

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 that react with each other to give out heat and light. But there is no such chemical reaction taking place on the Moon. Since it doesn’t burn any hydrogen, there is no light of its own as well. So. the Moon doesn’t qualify to be a star!

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 hot and cold air. When light passes through these gases, it gets slightly affected by these factors and bends a little from the ground, it appears that the stars are twinkling.

Oh, wait! It that way a coin on the floor of the swimming pool appears to be twincling and dancing? It seems the light just can’t stay in a straight line because of these distraction! Just like Robbu in school!

Remote controls are pretty amazing things. With just a press of a button, you can change the volume of the TV or turn on the AC. Hava you ever wondered what makes a remote control work?

Ok, let’s explore the TV remote. If you see carefully, you will find a little spot at the tip of your remote. Does it look like a fake eye or may be a plastic bead? Yes, you got it right! Have you notices how this little eye lights up when you press the buttons on your remote? So, when you press the remote buttons, this little eye sends a signal of light to the TV. Thought you cannot see this light but the sensors on Tv can catch it. So your TV now know what to do.
