00:00:00.000 --> 00:00:10.543
How much exposure time did it take to capture the Hubble Ultra Deep Field image?

2
00:00:10.543 --> 00:00:14.800
One of the neat things about the Hubble Ultra 
Deep Field and one of the things that made it so  

3
00:00:14.800 --> 00:00:21.498
unique was how long it took us to take that image.
It's a very, very long exposure time, 11.2 days.

00:00:21.498 --> 00:00:24.720
"11 Days"

5
00:00:24.720 --> 00:00:29.440
What's more important is how 
many orbits it took us to do that.

6
00:00:29.440 --> 00:00:38.363
400 orbits of Hubble data to take 
that image, that's a lot of orbits!

7
00:00:38.363 --> 00:00:41.760
A lot of Hubble time, you only 
get 15 orbits a day to take  

8
00:00:41.760 --> 00:00:48.800
400 orbits and say we're going to observe 
this one spot in the sky for 400 orbits.

9
00:00:48.800 --> 00:00:57.753
I think the results from the science was 
amazing what they saw was spectacular!
