The Hubble Ultra Deep Field
Check out this awesome video about the HUDF or Hubble Ultra-Deep Field from 2012. A few years ago during spring break my wife and I went to the Exploratorium in Balboa Park, San Diego.
We went specifically to see the IMAX movie about the Hubble Ultra-Deep Field but it was the Deep Field Images taken in 2009. However, in 2012 the astronomers used Huddle Space Telescope to do it again. This time they left the shutter open for a 11 days pointed at an even darker spot in space. Watch the video below to see what the scientist discovered.
It’s amazing what images you can produce when you let light fall on your sensor.
The Hubble Ultra-Deep Field (HUDF) is an image of a small region of space in the constellation Fornax, composited from Hubble Space Telescope data accumulated over a period from September 24, 2003, through to January 16, 2004. Looking back approximately 13 billion years (between 400 and 800 million years after the Big Bang) it will be used to search for galaxies that existed at that time. The HUDF image was taken in a section of the sky with a low density of bright stars in the near-field, allowing much better viewing of dimmer, more distant objects. The image contains an estimated 10,000 galaxies. In August and September 2009, the Hubble’s Deep Field was expanded using the infrared channel of the recently attached Wide Field Camera 3 (WFC3). When combined with existing HUDF data, astronomers were able to identify a new list of potentially very distant galaxies.
Located southwest of Orion in the southern-hemisphere constellation Fornax, the image is a bit over 3 arcminutes across. This is just one-tenth of the diameter of the full Moon as viewed from Earth, smaller than a 1 mm by 1 mm square of paper held at 1 meter away, and equal to roughly one thirteen-millionth of the total area of the sky. The image is oriented so that the upper left corner points toward north (−46.4°) on the celestial sphere.
On September 25, 2012, NASA released a further refined version of the Ultra-Deep Field dubbed the eXtreme Deep Field (XDF). The XDF reveals galaxies that span back 13.2 billion years in time, revealing a galaxy theorized to be formed only 450 million years after the big bang event.
