$pointlessbickering: One of the most significant photos ever taken. It blew my mind away when I first saw it. This is the legendary Hubble Ultra Deep Field. From September 24, 2003 to January 16, 2004, NASA made the Hubble Space Telescope point to a small region in the sky around 11 square arcminutes, taking in all the light it could. (That’s a huge exposure time, to relate it to regular cameras.)This is what they saw. There are ~10,000 celestial objects in this picture. Almost all of them are galaxies.Galaxies.Think about that. Galaxies. What galaxy do we live in? That’s right, the Milky Way. Look up at the sky at night. Even in urban areas, you see quite a bit of stars. Go to rural areas, and you see hundreds in the sky. Possibly thousands. Those are just a small fraction of the ~100 billion stars in the Milky Way. Those are stars in just one galaxy. Imagine 10,000 galaxies, with millions to billions to maybe even trillions of stars, with the possibility of some having planets. That’s several hundred thousands of planets, as a rough estimate.Do you really think there’s just us in the universe?$
