Hey Internet!
Did you know that if we look into the farthest reaches of the night sky, past all the stars
and galaxies and superclusters of galaxies, we see light that’s basically a picture
of the big bang and has been traveling for 13.7 billion years to reach earth?
To help you learn more about how awesome this “Cosmic Background Radiation” is, we’ve
built a cool map that lets you explore the earliest picture of our universe.
Welcome to
Now, scientists who measure the temperature of this ancient radiation have noticed that
it’s hotter or colder in different parts of the sky, which they usually draw as red
and blue blobs.
But \hsince this is the oldest light in the universe, we thought it deserves a bit more
excitement, so we've drawn the "hot spots" as mountains, the “cold spots” as oceans...
And just tried make the whole thing a lot more fun.
Since it can be hard to get oriented on an unfamiliar map, we’ve also added constellations
so you’ll always know what part of the night sky you’re seeing.
Not to be outdone by google maps, we have different overlays, too - like the same view
of the sky as seen in infrared.
Here’s Andromeda!
Just click on the labeled astronomical objects to see sweet pictures and learn more about
But what about the Cosmic Background Radiation?
It also has tons of cool features, they’re just not labeled yet.
So we invite you to pick your own special spot on the map, (just hold shift and click)
and choose a name that will become part of the MinutePhysics map of the cosmos.
