Here is one of the most colorful deep field images ever taken by the amazing Hubble. Below is a video of the image which I like because it shows how small an area is being looked at and how much is there.
The video is great but take a look at a large version at HubbleSite. You will be treated to the full image, a composite of separate exposures taken in 2003 to 2012 with Hubble’s Advanced Camera for Surveys and Wide Field Camera 3. It is AMAZING!
