Hubble Ultra Deep Field - Wonders of the Universe; Messengers - BBC

In 2004, we peered further back in time than ever before and captured the light from the most distant galaxies in the universe. The image is called the Hubble Ultra Deep Field. Thank you. It's a picture taken by the Hubble Space Telescope over a period of 11 days and it focused its camera on the tiniest piece of sky just below the constellation of Orion. Now it's a piece of sky that you would cover if you took your thumb, held it in front of your face and then moved it 20 times further away. But the Hubble captured the faintest light from the most distant regions of the universe and it took this photograph. Now almost every point of light in that image is not a star but a galaxy of over 100 billion stars. The most distant galaxies in that image are over 13 billion light years away. That means that the faint light from those galaxies began its journey to Earth 13 billion years ago. That's over three times the age of the Earth.
