This is the Hubble Ultra Deep Field image and it’s undoubtedly one of the most important (and enormous) photographs ever taken, as we got a peek at some of the most distant galaxies. All of which, were not known to exist beforehand. In 2003, Hubble pointed its telescope at an empty patch of sky
In this small sliver of the Universe, there are over 10,000 galaxies. Each of which are the home to billions upon billions of stars. It’s quite likely that a large majority of the stars contained in the galaxy would have planetary systems that’s very similar to our own. Maybe life has evolved on hundreds of those planets? Perhaps maybe even a few of them are hosts to intelligent life? Who knows. Some intelligent species located far away from Earth might be doing the same thing we are, discovering their own little sliver, with our galaxy being one of those tiny points of light, far, far away from them.
This astonishing picture was taken by the Hubble Space Telescope in 400 orbits and 800 exposures. Because of this, you might think it covers a large portion of the sky when in fact, it only photographed roughly one thirteen-millionth of the observable Universe! It’s hard to imagine that we are alone based on those numbers alone!
One more interesting note to make is that the galaxies imaged in this photograph may not exist anymore… at least not in their present form or location due to the expansion of the universe!
