Hubble shows the deepest view of the Universe ever seen
The Hubble Telescope has done it again and captured the deepest view into the Universe with an image of galaxies 13.2 billion light years away. The picture you see (above) is called the eXtreme Deep Field, or XDF, that combines 10 years of Hubble Telescope views into a single image of the sky.
The last time we peered that deeply into the night’s sky, the Hubble focused on a cluster of galaxies 13.1-billion light years away . While that 0.1 billion light years might seem like a tiny improvement, the image you see above is actually a composite of 5500 galaxies captured from a small part of our sky and an infinitesimally smaller slice of the entire universe.
Feeling small and insignificant yet?
The image is made from thousands of photographs taken since 2003 using Hubble's Advanced Camera for Surveys and the Wide Field Camera 3. Throughout the 10-year project, the cameras took 2,000 images of the same patch of sky. It's the equivalent of an exposure time of 2 million seconds. Can't do that with your DSLR.
The XDF image isn’t just a view of the farthest-away galaxies spotted so far; it's also a look into the universe’s past because the light we’re seeing is actually from 13.2 billion years ago. The universe is theoretically 13.7 billion years old, so we could be just 0.5 billion light years shy of seeing first stars and planets ever formed after the Big Bang.
