Due to the gravitational force in the core of Sun, Hydrogen atoms are drawn towards the core where a huge number of atoms are gathered making the core very very dense, because of this dense core, the hydrogen atoms collide with each other and stick to each other forming Helium atoms (He) , this proc...

How was the Solar system formed!

About 4.5 billion years back, a cloud of gas and dust started collapsing in on itself due to shock waves from a nearby supernova explosion. (stage A in the picture)

As more and more material collapsed towards the center, the cloud started spinning faster and faster and developed gravity which made it a flat spinning disk of dust and gas. (stage B)

When enough material was collected at the center of the disk, Nuclear fusion reaction began. Nuclear fusion happens when hydrogen nuclei fuse together to form helium. (stage C)
This nuclear fusion released a lot of energy and that’s how Sun was born.

Some parts of the dust material were left behind and they clumped together to form planets, dwarf planets, asteroids and comets. (stage D)

Dust and rocks stayed relatively closer to Sun and formed the rocky inner planets, The gases wandered farther to form outer gaseous planets.
The remaining material formed the Asteroids, comets, dwarf planets etc.

Trying to understand Science through books is like learning swimming by sitting on the pool side and watching people swim. Science is all around us; at this very moment, from my brain constructing the script and then instructing my hands to type the sentence into the computer to you using the convex...

What is a day !

How do we define a day, is it -
-The time it takes for Earth to complete one rotation on its axis or
-The time from one noon to the other !
Actually both are different and both are defined as a day

Sidereal day: The time a celestial body takes to complete one rotation on its axis. For Earth, Sidereal day is 23 hours, 56 minutes & 4.1 seconds.

Solar day: From one noon (when the Sun is exactly overhead) to the next noon is a Solar day.
In the picture, point A will complete one rotation on its axis in 23 hours and 56 mins, however by that time Earth would have moved from point X to point Y on its orbit around the Sun and will take another 4 minutes to have completed one rotation around the Sun (and is noon again).

Because of this additional 4 mins, a Solar day is longer than a Sidereal day.

This image is of a unique 6 sided jet stream (A jet stream is a band of high speed winds) on the north pole of Saturn. It was taken by spacecraft Cassini while it was orbiting the ringed planet.
This jet stream is about 32,000 kilometer wide and has wind speed reaching as high as 320 km/hour.

There is a massive hurricane within the hexagon. You can see the eye of the hurricane at the center of the hexagon. The hurricane and the hexagon are spinning anti-clockwise.
Along with the main hurricane, there are numerous smaller storms within the hexagon.
The sides of the hexagon are about 14,000 km long; which is more than the diameter of Earth.

The Cassini spacecraft is in orbit around the Saturn since 2004 and is in the last phase of its exploration of the planet, as of 2017.

Our Solar system is part of the Milky way Galaxy.

Milky way is a spiral shaped galaxy and is about 100,000 light years in diameter.
It is also 1,000 light years in thickness and houses up to 400 billion stars.

Sun is orbiting around the centre of Milky way galaxy and takes about 230 million years to complete one orbit.
Milky way galaxy became so huge by engulfing other smaller galaxies.

Any picture that you see of the Milky way galaxy is a hypothetical image, because we are sitting inside the galaxy and cannot go out of it to take an image from outside .

Our Sun is a type of Star that is called a yellow dwarf. Sun is in the middle of its life at the moment and in last 4.5 billion years, it has remained mostly unchanged while Earth and the rest of the Solar system took shape. Sun will remain in this stable state for another …

This picture was drawn by Isaac Newton and depicts why does moon not fall on Earth despite Earth’s gravitation pulling the moon all the time. If I am standing at point V on Earth and drop a ball from your hand, it will fall straight on the ground because Earth will pull the ball; However …

  – What happens when you throw a ball in the horizontal direction,  the ball travels a while (it is actually travelling in an orbital path around the Earth) and then falls on the ground; Now, what if some invisible force stops the ball while it is travelling horizontally, the ball will fall straigh...
