The world is a very small place, this humbling video will make you take a second guess at reality

I knew Earth was small, but I didn't realize that even our sun was THAT small compared to some other stars. I knew it was considered a "small" star, but nothing like that. I was just like holy crap throughout the video as the stars just kept getting bigger and bigger.

And there may be many bigger stars that have yet to be discovered.
 
puts into perspective how large Betelgeuse really is. And to think, it could go supernova ANY moment (within the next 1000 years it is thought it will blow, but think, stars live so long, that 1000 year prediction isn't exactly accurate, also since some astronomers think it is in its carbon-burning phase, meaning its extremely close to going supernova).
think of the explosion. We'll see the supernova, even in daytime, for a few months... its only about 500 light years away. But it won't hurt us.
 
The thing that's cool about looking at distant stars is that you're really looking into the past, some of those stars no longer even exist.
 
Of all thoes huge bloated gas giants, it seems only ours can sustain life.

Another example of how size doesn't matter. 😀

Yup. Just a wee little, nondescript yellow dwarf star.

And here we are, that pale blue dot.
 
Music was a bit much, but cool video. I study astronomy so the scale of these things doesn't surprise me anymore, but it still amazes me.

Not really...there's an upper limit of how big a star can be.
 
But think. All that matter tied up in huge stars, and they are useless for life as we know it. And think further, that most stars are smaller than ours. And many may not have planets, or only a hot jupiter or two. Even though earth is a small place, it is also very very rare. It's a gem of a world. There probably aren't many like it.
