hey guys, so i was thinking of doing this whole segment of Fun Science coming from a science fan. So this is the first episode of Fun Science ! :D
So stars are awesome, and I dont mean as the "Oh my god, wasnt the new episode of glee awesome?" kind of awesome, I mean proper awe inspiring awesome.
So, to start you of, stars are basically ginourmous super hot luminous balls of plasma floating around in space. And when I say plasma, yes I mean the same plasma you'll find in plasma screen t.v's and plasma lamps. There's somewhere in the region between 200 - 400 billion stars just in our Milkyway Galaxy. And there are over a 70 billion galaxies in our whole universe.
So, if you do the math, there are quite alot of stars. You probabaly already knew that stars dont really look like twinkly stuff. There are two reasons why the stars look like tiny little sparks of specks of light from here on earth and the first reason is because they are very distant, so with our naked failuble human eyes, we cant see them very well.
The second reason, the reason why we see stars as they're twinkling because, SPOILER ALERT: Stars dont actually twinkle. Is because the light from the star enters our atmosphere, it gets refracted, or bent a little bit, and so we interpret that the stars look like they're twinkling. In reality, stars actually look like a mini sun. And the sun in particular is a very known star, you might've heard of it, its pretty popular among us living creatures.
It gives us light and heat and stops us from dying and stuff like that. And eventhough the sun is the closest star to here on earth, the sun is 30000 years old. Science is awesome !! If you wanted to, you can fit a million earths in the sun, cause its a 109 times bigger than the earth, but if you take the biggest sun we know of, called VY Sanis Majoris, the Sun is about one pixel big compared to it. And you can think of how big WE are compared to that, PRETTY INSIGNIFICANT. And we are literally made of star stuff. :D
So we've come to the end of Fun Science today, but if you've got any other suggestions of what i should talk about next, suggest in the comment box. SO i'll see you next time folks, good bye ! :)
