The HRS contrasted with the FOS in that it concentrated entirely on UV spectroscopy and traded
the extremely faint objects for the ability to analyze very fine spectral detail.
The HDST would be able to study
extremely faint objects that are 10 to 20 times dimmer than anything that could be seen from the ground with the planned large, ground - based telescopes.
With its high - sensitivity, NIRES will also allow astronomers to observe
extremely faint objects found with the Spitzer and WISE infrared space telescopes.

extremely faint objects, objects we just can't see from Earth,» Rhee said.
For
extremely faint objects, the added goal is to get enough duplicates of that image in order to layer them together later.
«Thanks to this detection, the team has been able to study for the first time the properties of
extremely faint objects formed not long after the big bang,» said lead author Leopoldo Infante, an astronomer at Pontifical Catholic University of Chile (Pontificia Universidad Católica de Chile).

A new analysis of galaxy colors, however, indicates that the farthest
objects in the deep fields must be
extremely intense, unexpectedly bright knots of blue - white, hot newborn stars embedded in primordial proto - galaxies that are too
faint to be seen even by Hubble's far vision — as if only the lights on a distant Christmas tree were seen and so one must infer the presence of the whole tree (more discussion at: STScI; and Lanzetta et al, 2002).
