Discovering Our Galaxy Is Not The Only One ➶
I don’t remember from where I stole the ideas I often repeat to people that photography is a good teacher and that there is wisdom in uncertainty, but here is more proof.
Due to the work of Edwin Hubble, it is now known that the Milky Way is only one of as many as an estimated 200 billion (2×1011) to 2 trillion (2×1012) or more galaxies.
Mike Johnston writing about the Hubble Ultra Deep Field Photograph, which shows around 10,000 galaxies:
This is not the prettiest picture ever made, but it is certainly one of the most amazing. It is a picture of a tiny, nondescript patch of sky with “nothing in it,” in the constellation Fornax, below Orion. To put its angle of view in perspective, science writer Chet Raymo explains, take two pins or sewing needles and, at arm’s length, cross them. The small square where the two pins overlap is approximately the visual area represented by the Hubble Ultra Deep Field photograph.
I find it quite beautiful, the smudges of colored light like distant glowing jewels, each composed of billions of stars and who knows how many planets.
