Hubble Deep Field: looking back in time

The Hubble Deep Field is an image taken of the sky that is the size of a dime held 75 feet away, and yet thanks to its long exposure time and the incredible resolution of the Hubble Space Telescope this image contains more than a thousand galaxies! Even though the Hubble Deep Field image was taken more than a decade ago, it is still being used (along with the Hubble Ultra Deep Field) to answer many questions about galaxy formation. In this talk, I will discuss the Hubble Deep Field and some of the current research on galaxies it has instigated.
