Interview with Dr. Harry Ferguson: Part 2

Hubble Goes 'Deep' to Sample Young Galaxies

NASA's Hubble Space Telescope reached back to nearly the beginning of time to sample thousands of infant galaxies. This image, taken with Hubble's Advanced Camera for Surveys, shows several thousand galaxies, many of which appear to be interacting or in the process of forming....

Chandra Deep Field-North

The Chandra Deep Field-North image was made by observing an area of the sky over half the size of the full moon for 23 days. It is the most sensitive or "deepest" X-ray exposure ever made. By combining the Chandra and Hubble data for this field, astronomers can take a census of...

Cosmic Timeline

Observatories continue to reach farther back in time to study the evolution of stars and galaxies. This illustration shows that the Chandra X-ray Observatory and the Hubble Space Telescope's Advanced Camera for Surveys looked back billions of years to see the first galaxies....

GOODS Mosaic

The GOODS survey, with targets in the northern and southern skies, covers 60 times the area of the original Hubble Deep Field observations, taken in 1995. In fact, the survey encompasses such a wide area that astronomers tiled together a series of exposures from Hubble's...

GOODS Galaxy Sequence in Time: Near to Far

This video scrapbook, assembled from a series of Hubble Space Telescope photographs, shows how galaxies evolve over time. The sequence begins with a small clump of stars that existed when the universe was less than 1 billion years old and ends with a disk galaxy that existed...

Zoom In: Chandra-HST Comparison

This video compares the large area in the northern GOODS field, observed with the Chandra X-ray Observatory, with the smaller region viewed with Hubble's Advanced Camera for Surveys. The video begins with the Chandra field, which is over half the size of the full moon, and then...

X-Ray Sources

This video sequence pinpoints the seven X-ray sources [supermassive black holes] discovered in the southern field with the Chandra X-ray Observatory that cannot be seen in the Hubble view. The sequence begins with a view of the full Chandra field. Small boxes appear which...
