Looking Back into Time With the XDF

Hubble eXtreme Deep Field (XDF)

The eXtreme Deep Field, or XDF, was assembled by combining 10 years of NASA Hubble Space Telescope photographs taken of a patch of sky at the center of the original Hubble Ultra Deep Field. The XDF is a small fraction of the angular diameter of the full Moon. The Hubble Ultra...

XDF Moon Comparison

This image compares the angular size of the XDF field to the angular size of the full Moon. The XDF is a very small fraction of sky area, but it provides a "core sample" of the heavens by penetrating deep into space over a sightline of over 13 billion light-years. Several...

Hubble eXtreme Deep Field Pushes Back Frontiers of Time and Space

This video explains how astronomers meticulously assembled mankind's deepest view of the universe from combining Hubble Space Telescope exposures taken over the past decade. Guest scientists are Dr. Garth Illingworth and Dr. Marc Postman.

Flight Through the Hubble eXtreme Deep Field (2D Zoom and 3D Fly-Through Sequence)

This video begins with a zoom into the small area of sky that the Hubble Space Telescope observed to construct the eXtreme Deep Field, or XDF. The region is located in the southern sky, far away from the glare of the Milky Way, the bright plane of our galaxy. In terms of angular...

Flight Through the Hubble eXtreme Deep Field

This scientific visualization depicts a flight through the galaxies in the Hubble eXtreme Deep Field (XDF). Using measured and estimated distances for approximately three thousand galaxies, astronomers and visualizers constructed a three-dimensional model of the XDF galaxy...

Meet the Hubble eXtreme Deep Field Observing Team (Webinar on September 27, 2012)

A new, improved portrait of Hubble's deepest-ever view of the universe, called the eXtreme Deep Field, or XDF, looks far away and back in time to reveal faint galaxies at one ten-billionth the brightness of what the human eye can see. This is the culmination of 10 years of...
