Hubble's Deepest Look Yet

Yesterday Nasa released a photo taken by the Hubble telescope and has identified roughly 5,500 galaxies in just one small section of the universe.  The faintest of these are one ten-billionth the brightness of what the human eye can see, so don’t try and pinpoint them in the night sky.   It’s hard to even grasp at how small of a section this is of the nights sky.  One comparison I read was to basically consider this to be one 30-billionth of the visible night sky.  So multiply 5,500 by 30 billion and that would be the potential number of galaxies in the known universe.

The brain has a hard time simply comprehending that number, much less the fact that a single galaxy is generally made up for many stars.  Stars that may or may not be surrounded by multiple planets.   Planets that may or may not be capable of sustaining life as we know it, or even as we don’t know it.

It’s amazing when you think about, and possibly even more amazing when you think about how little we actually know about the universe.   How much of what we know as a planet could very well, and probably will come to be realized to be false.   It is unfortunate that the budget of these programs is being cut instead of increased so that we can learn more.  At some point our species will come together as one and look towards the sky together and ask aloud ‘What else is out there?’.  However, what it will take and what pivoting event it will take to get there is really a speculation of many science fiction writers.
