NASA has just updated their mind-boggling Hubble Ultra-Deep Field image to include ultraviolet data (which should help astronomers to study some of the earliest star formation in the universe). But get this: the image covers less than one ten-millionth of the total area of the sky, yet almost every point of light in the image is an entire galaxy. And if you could be bothered to count all the points of light in the image - there are about ten thousand of them!
Ten thousand galaxies. Quadrillions (1,000,000,000,000,000s) of suns - and perhaps as many habitable worlds - in an unremarkable speck of sky not larger than the head of a pin held at arm's length. The mind boggles.
It's also incredible that the light from the oldest galaxies in the image has been travelling to us for more than 13 billion years, meaning we're essentially looking back in time 13 billion years. For comparison, the Big Bang is believed to have taken place 13.8 billion years ago.
Be sure to check out the full-res image here.
It's gorgeous, stunning and a tad overwhelming. NASA says it's also made up of the most colorful deep space images ever captured.
