1 00:00:00,000 --> 00:00:10,020 How far has Hubble seen into the universe? 2 00:00:10,020 --> 00:00:13,599 Hubble has been able to observe objects way out to almost what the edge of the 3 00:00:13,600 --> 00:00:17,160 universe about 13 and a half billion light years 4 00:00:17,160 --> 00:00:19,840 1 light year = 5.879 trillion miles 5 00:00:19,840 --> 00:00:23,760 Hubble was never designed or thought it could see that far out, 6 00:00:23,760 --> 00:00:27,119 but because of the advances in the instruments that we've been able to put 7 00:00:27,119 --> 00:00:29,679 up on the telescope and also the cleverness of the 8 00:00:29,679 --> 00:00:33,280 scientists they've come up with very interesting observing scenarios 9 00:00:33,280 --> 00:00:37,120 doing these really deep exposures where we just sit there for orbit after orbit 10 00:00:37,120 --> 00:00:40,559 after orbit, gathering the photons we've been able to 11 00:00:40,559 --> 00:00:46,800 push Hubble out very very far. These very very deep exposures that 12 00:00:46,800 --> 00:00:48,399 Hubble has been able to take we have seen 13 00:00:48,400 --> 00:00:55,080 right to the edge of the universe 13 and a half billion years. 14 00:00:55,080 --> 00:01:08,100 [ INSPIRING MUSIC ]
