New Hubble instruments would illuminate early universe
Quote:
WFC3's sensitivity and wide field of view would make it 15 to 20 times more efficient at searching for faint, distant galaxies than Hubble's Near Infrared Camera and Multi-Object Spectrometer (NICMOS), which has previously been used for this sort of work.
...
COS would be especially useful for studying the gas that floats between galaxies, Niedner says. This would help astronomers survey the diffuse gas in space and understand how star formation and supernovae have affected it. The instrument would also help astronomers study developing stars.
