From 2003 to 2014, NASA’s Hubble Space Telescope observed the same tiny region through 7 different wavelength bands.
They produced the Ultra-Deep Field and eXtreme Deep Field images of Hubble.
Here are 10 scientific revolutions hiding inside.
1.) The most distant red dwarf star from the Milky Way ever seen: UDF 2457, located 59,000 light years away.
2.) The largest and brightest deep galaxy, UDF 423: a giant spiral from 7.7 billion years ago.
3.) The ancient galaxy HUDF-JD2 appears only 0.9 billion years after the Big Bang, having already reached 600 billion solar masses.
4.) The ultra-low red galaxy UDFj-39546284 first deceived us: it is an intertwined galaxy imitating a more distant galaxy.
5.) UDFy-38135539 is also controversial: his disputed distance measurements mean he could be another intruder.
6.) The star formation peaked around 11 billion years ago, and has been falling since.
7.) Dozens of cosmic tadpoles have shown that interacting and merging galaxies are common in the young, evolving universe.
8.) The deepest view of the XDF has ever found 5,500 galaxies in an area covering only 1 / 32,000,000th of the sky.
9.) 170 billion galaxies would be visible if Hubble could see the entire sky, which would take millions of years.
10.) He taught us that 2 trillion total galaxies occupy the Observable Universe, with the Hubble limits unable to penetrate further.
