G3CK0 writes "Scientists at NASA's Swift satellite and Gemini Observatory on Mauna Kea have observed the most distant object in our universe. The object, a Gamma ray burst, has been measured at a redshift of z = 8.2. The light from this object has been traveling over 13 of the estimated 13.7 billion year age of the universe. An interesting note, this observation falls under what is know as a TOO (Target of Opportunity). Normal observations at Gemini are carried out via queue mode. When time sensitive events happen, a decision can be made to suspend the queue (and classical observing) in order to observe the TOO." Link to Original Source
