Keck turned the Hubble Deep Field
from a pretty picture into a scientific treasure trove.
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.
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.
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.
Since the completion of the Hubble Deep Field
North, several sky surveys have intensified the flood of data.
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.
Meanwhile, Michael Merrifield (University of Nottingham, England) says that analysis of Hubble Deep Field
galaxies indicates that barred spirals were virtually absent until the universe was about half its present age.
Richer of the University of British Columbia in Vancouver, and their colleagues used Hubble to reexamine the Hubble Deep Field
North 2 years after the telescope first imaged this region of sky (SN: 1/20/96, p.
THERE ARE LONG, NARROW COSMIC PROBES SUCH AS THE HUBBLE DEEP FIELD
, AND THERE ARE WIDE-AREA SURVEYS THAT COVER BROAD SWATHS OF THE CELESTIAL SPHERE TO SHALLOW DEPTHS.
Spectra taken last year by the Hubble instrument confirmed that the galaxy, located in a region adjacent to the Hubble Deep Field
North, has a redshift of 6.
In another blow to the halo-white-dwarf theory, astronomers who claimed earlier to identify some of these stars in the Hubble Deep Field
North (S&T: January 2000, page 22) have withdrawn their claim.
It counted faint, faraway galaxies in the tiny patch of sky called the Hubble Deep Field
, which was scrutinized by the Hubble Space Telescope.
