→ Holy shit, if you've ever wandered the scale of things, this is what you need.


In this little flash game you can scroll and see how small a hydrogen atom is versus a red blood cell versus a human versus the moon versus the Andromeda Galaxy omg it blew my mind. 
It include everything from the strings in the String Theory to the visible Universe.

It’s insane.

So very cool.  The eerie sounds of Saturn.  Radio emissions from Saturn’s aurorae vary over a range of intensities and frequencies in a hauntingly beautiful soundtrack. Our ears can only pick up a small range of available frequencies, but Cassini’s instruments gather information over a much broader spectrum. NASA scientists shifted the frequency data down by a factor of 44 to translate the emissions into our audible range, and then sped it up a bit - 20 minutes of recording is played back in about a minute. It’s strange to our ears, but not so strange overall - the complex radio spectrum with its rising and falling tones is similar to the auroral radio emissions from Earth’s northern and southern lights. 

About Cassini. Cassini completed its initial four-year mission to explore the Saturn System in 2008 and its first extended mission in 2010. The healthy spacecraft continues to make new discoveries in a second extended mission - the Cassini Solstice Mission - scheduled into 2017.  

Well that’s just fucking amazing.

I see a bunch of people saying it’s not a big deal that we’ve landed Curiosity and that if it doesn’t find aliens or the cure for cancer then “its a waste if money.”

OKAY.

I would LOVE to see you apathetic know-it-alls to design a scientific laboratory on wheels the size of a mini-cooper and land it safely on a planet literally 149,598,000 km away on only a couple million dollars.

DO IT.
I DARE YOU.

Reblog if you’re planning on watching the Lyrid meteor shower this weekend!

Oh, just me?
