This is the Most Zoomed-In Photograph Ever Created by Mankind | Book Week 2016 | Scoop.it
What you’re looking at is the most zoomed-in photo ever shot by mankind. Titled the eXtreme Deep Field (XDF), a followup to the famous Hubble Ultra-Deep Field photo created in the mid-2000s. Scientists combined 10-years-worth of Hubble Space Telescope photos to create this resulting image that shows 5,500 individual galaxies, some of which are one ten-billionth the brightness of what our human eyes can see.The amount of photography and imagery that went into this image is staggering. The Hubble “space camera” was pointed at this tiny patch of sky for a total of 50 days, with a total cumulative exposure time of over 23 days(uber-long-exposure photography, anyone?). This resulted in 2,000 individual photos showing the same little section of the sky, all of which went into creating this photograph. It’s the “deepest image of the sky ever obtained” that reveals the faintest and most distant galaxies ever seen.
