3.1.4 Hubble Ultra Deep Field

The Hubble Space Telescope observed a single area for about 100 hours in order to collect sufficient light from distant galaxies.

The image, known as the Hubble Ultra Deep Field (UDF) is of a patch of sky only about one tenth of the size of the full moon in the night sky. The image shows thousands of galaxies with different redshifts.

In the next part of the course, you will look at the variety of shapes and sizes that galaxies come in. Before that you’ll take your photo of Orion for this week.
