3 Stars and...

I've been watch, yet again, a video with Doctor Neil deGrasse Tyson, PhD Astrophysics. And he said something, that I just had to share with you, becouse its so fantastic and mind blowing, that it can not be said.

Most of you have probebly heard of the Hubble Telescope, if not, here's the gist of it. Its a big freakin camera/telescope in orbit around our little blue and green speck in the universe.
And this telescope is able to see so many wonderful things, and in many different ways, like near-ultraviolet and near-infrared.


This one time thou, between september 24 2003 and january 16 2004 it took 800 pictures on a small area of the sky, or space, that didn't have anything in it. Nothing. It was just black (or void as space doesn't have color).

And the image that came back contained a total of 3 stars.... and...

The 3 stars, are the ones that look like stars. The ones with spikes on em.
Besides the stars with the spikes... every single dot, swirl and disc in that image, is a galaxy. Every one of them. And each of them, are very very far away, roughly 13 million light years away. And they were formed around 400-800 million years after the big bang.

Now to take a picture like this, obviously takes a long time. And if they were to take pictures like this of the entire sky, it is estimated to take about a million years... thats: 1 000 000 years... a realy freakin long time.

I just found all this to be way to fascinating to not share with you.

You are welcome.
