Investigation of age and metallicity gradients and dust extinction in disc galaxies in the Hubble Deep Field
Unfortunately, spectra can be obtained only for relatively bright objects, so the distances of the faintest galaxies in the Hubble Deep Field
One caveat, Labbe notes, is that Hubble Deep Field
South is an extremely tiny patch of sky, taking up less than 1 percent of the area of the full moon.
One is the Hubble Deep Field
image made with the orbiting observatory in 1996.
Senior editor JOSHUA ROTH was among the journalists in attendance when the original Hubble Deep Field
was unveiled eight years ago and again when its Ultra Deep successor debuted last March.
Since the completion of the Hubble Deep Field
North, several sky surveys have intensified the flood of data.
The Hubble Deep Field
campaign also proved that releasing a stunning image within days of acquisition could capture the imagination of the astronomical community and the public alike.
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.
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.stsci.edu).
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.
Observations of the Hubble Deep Field
North and South, as the patches of sky are now called, have produced the sharpest images of galaxies ever made.
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.
