Hurrah! My blog turns an year now…

Hurrah! It’s been an year now. One thing’s for sure, blogging community here is awesome. I learnt so much here. Now, my blog turns an year and I got an year of experience in blogging. This is a huge thing to me. So, I thought, why not make this article a huge one too. Before you get mad at me scrolling down and down and wondering where it ends, let me explain you something.

When I did my 100th article with 100 followers (Celebrating 100th article with 100 followers). I thought I would write my 200th article with 200 followers but, it didn’t happen now. This is my 153rd article with 210 followers;);) The funny thing is I got the followers count, as I said before  bloggers here are really awesome, but I didn’t reach my articles count;);) It’s pretty genuine though, you don’t want to read junk and I don’t want to write articles to just satisfy the count.

Moving on, as you scroll down, hopefully you find some really interesting articles. And there are so many of them. Trust me you won’t be disappointed because, all my favourite articles are listed below. The good thing is, almost all of my articles are listed. Favourites till my 100th were listed in one article and from 100th to this particular article are listed below. So, this is an eye feasting article, atleast to me;)

If you have read and still remember my 100th article you might have noticed that, a few dialogs are similar right? Yeah! In case you don’t reach the end of this article reading and scrolling, let me tell you something. Thank you so much for making this happen, thank you for your support and thanks for your suggestions. Appreciate it!

What is Supernova?

In astronomy, we often hear the word “Supernova”. Let’s see, what actually a Supernova is?

 Supernova is an event where an explosion of a huge star takes place. These blasts produce some heavy material in the universe including some elements, like iron, which make up  planets. Not all stars become Supernova though.

So, there are two types of supernovae.

White Dwarfs

White Dwarfs is something with the size of our earth and with 8 times the mass of our sun. This explains how dense it is. With this high density, it pulls mass from the neighbouring mass, using its gravity. By taking in the mass, it reaches a level called “Chandrasekhar limit”. At this instant, the star becomes unstable and supernova takes place. In turn, it forms something called Neutron star.

Star Fusion

 It occurs when stars core’s fusion process runs out of fuel. They can briefly outshine entire galaxies and radiate more energy than our sun will, in its entire lifetime. Stars are high nuclear reactors producing energy by fusing hydrogen into helium. Running out of fuel is nothing but, running out of hydrogen. With this, the helium is fused into heavier elements and supernova takes place, adding enrich elements to space clouds of dust and gas, further interstellar diversity, and produce a shock wave that compresses clouds of gas to aid new star formation.

Ultimately these supernovae are responsible for Black-holes and Birth of new stars too…

Move back and forth in time( TIME DILATION)

Time dilation leads us to time travel!! Sounds great, but kinda weird to explain. Your concept of relative speeds doesn’t work here.

If you and superman are flying with the same speed, then with respect to you, the superman is at rest. This isn’t the case with light, as long as your speed is less than light( though your speed is so close to light), the speed of light doesn’t change with respect to you.

If speed isn’t changing with respect to you, though you are moving, then what is changing? Well… The time is changing. So, this is the key for time travel.

Have you watched the movie “Interstellar”? Yeah you must. When the hero returns to his daughter from another planet probably in other solar system, his daughter becomes more than 90 years old( that is much older than her father). This is time dilation, because of his journey through wormhole.

You could do a flyby of a nearby star and return to Earth at nearly the speed of light, and a few years would pass on Earth while possibly only a few weeks or months would pass for you, depending on how fast you were going and how far away the star was.

Few of my recent articles are related to this one.  RELATIVITY (all about the Einstein’s special and general relativity) and the previous one Stars ( which proves that, even light with such great speed takes “Time” to reach us;)

There is another extension to this article, can you guess one?

 

 

 

 

Does stars really twinkle?

The actual stars don’t twinkle. The twinkling we see is due to the earths atmosphere. In fact the stars are glowing balls with never ending glow, placed trillions of kilometres away.

Light from these far away stars first enters the earths atmosphere, and bends while passing through different layers of the earths atmosphere and we get to see a point of light twinkle . Due to this refraction(bending of light), the stars appear to be twinkling. The technical term for this is “STELLAR SCINTILLATION”.

This twinkling of stars helps astronomers to differentiate planets from stars.

As we know, our own sun is a star, then why it doesn’t twinkle?

You guessed it, our sun isn’t so far away from our planet earth. For this reason the refraction is not noticeable.

Here’s a fun fact, when we look at a star, we actually look at the image of the star. In real time, the star may not be there at that particular position, because the light takes comparatively more time to reach our eye from the star.
