Very interesting stuff here! Using HAWK-1 scientists were also able to see extremely faint galaxies that date back to nearly the beginning of the universe. This is the stuff that should be front page news.The European Space Agency’s Herschel space telescope has discovered that previously unseen distant galaxies are responsible for a cosmic fog of infrared radiation. The galaxies are some of the faintest and furthest objects seen by Herschel, and open a new window on the birth of stars in the early Universe. Astronomers estimate that their are billions and billions of galaxies in the observable universe (as well as some seven trillion dwarf galaxies) .
