At a morning coffee meeting in the Institute's library, Williams and his colleagues first brainstormed the idea of a Hubble Deep Field
Investigation of age and metallicity gradients and dust extinction in disc galaxies in the Hubble Deep Field
One is the Hubble Deep Field
image made with the orbiting observatory in 1996.
BODY OF EVIDENCE Using one of these large-format infrared cameras on a high-precision telescope in Parnal, Chile, astronomers recently examined the Hubble Deep Field
South, a patch of sky that previously had been viewed for a solid week in visible light by the Hubble Space Telescope.
THE ORIGINAL Hubble Deep Field
image--the result of plumbing a nondescript patch of Ursa Major for 10 days and nights with the Hubble Space Telescope--changed the course of extragalactic astronomy when it was released in 1996 (see page 42).
That's twice the number of background galaxies detected in a landmark set of images--the Hubble Deep Field
North--taken from a different, smaller patch of sky by WFPC-2 in 1995.
How the Hubble Deep Field
Made Astronomical History
Many astronomers have used the data compiled from that region of sky, known as the Hubble Deep Field
North, as a basis for further studies at a variety of wavelengths (SN: 1/20/96, p.
Our exposure captured HST as it was imaging the Hubble Deep Field
North as part of NASA's Great Observatories Origins Deep Survey (GOODS) project (www.
Richer of the University of British Columbia in Vancouver, and their colleagues compared the 1995 images of the Hubble Deep Field
North, the region viewed in exquisite detail by the Hubble Space Telescope, with those that the telescope took 2 years later.
The group used Chandra to examine a patch of sky that includes the Hubble Deep Field
, a region scrutinized in visible light by the Hubble Space Telescope.
SEVEN YEARS AFTER THE FIRST HUBBLE DEEP FIELD
(HDF) PROVIDED a view of the faintest and most distant galaxies ever seen, a team of astronomers has determined redshifts for thousands of them--and has confirmed its earlier suspicions that vigorous star formation began surprisingly early.
