IMAGING WHAT WE CANNOT SEE: TEMPERATURE (AND THE WHOLE UNIVERSE AND THE PAST AND STUFF)
Okay now we're just getting ridiculous: this is essentially a 9 year long exposure. Okay its not quite a purely photographic image, its a data map of 9 years worth of data on Cosmic Microwave Background radiation. Again, microwaves are part of the Electromagnetic Spectrum of which light visible to our human eye is only a tiny fraction. Basically this image is looking so deep into space that it is able to see the so called cosmic Dark Ages and measure temperature fluctuations soon after the Big Bang- "soon" being 400 million years after the the Big Bang occurred. What did this show the super-nerds? That the universe is older than we thought (about 13.8 billion years old) and that at the time of these cosmic Dark Ages the universe was made up of about 95% dark matter and energy.
My brain has melted and I'm not sure I've got this all correct so you should click on the image above to read more about it!
