Región del cielo de la que se obtuvo el Campo Ultra-profundoHubble Ultra Deep Field During 2004, International Space Telescompe focused its lenses to a tiny piece of sky, a piece of hardly the srelative size of a moon crater, something like looking at the saky through a straw. That sky region, at Fornax constellation, looks like a black void, like there was nothing on it.
 
The telescope focused on that tiny point dor about 1 million seconds (about 11 days exposition), splitted into 800 snapshots of 21 minutes each, from September 2003 to January 2004.

After the observation finished, the result was the called Hubble Ultra Deep Field, the farthest portrait, and at the same time the oldest image of the known universe. On such sky region appeared thousands of galaxies, some of them (the most redded ones), were at about 13 billion light years. That is, they developed "only" 800 million years after the estimated date of universe creation. The light generated by those galaxies that we can see took 13 billion years to reach our planet.

To date, this is the oldest and farthest image of our universe, taking into account that the visible distance or "depth" depends on the time light takes to reach our planet, at a speed of 300.000 Km/second. It’s just imazing and unimaginable notice the vastity for our universe when using "human" scale. It is fascinating to see what hides beyond a small region of sky, such a cuantity and richness of objets.

May be that with the future space telescope James Webb, deep sky snapshots will reach nhigher distance and accuracy. allowing to improve the research and demonstration of the different hypothesis about how could our universe start.
