Hubble Sees the Universe in a New Light
News story originally written on October 9, 1998
Scientists have used a new instrument on the Hubble Space Telescope to
see farther into space then they ever have before. The Near Infrared
Camera and Multi-Object Spectrometer (NICMOS) can see galaxies that could
be over 12 billion light-years away!
One of Hubble's objectives is to search for the farthest and faintest
objects in space. Before now, the Hubble Deep Field
by the Wide Field and Planetary Camera 2 (WFPC2) was the farthest anyone
The WFPC2 takes pictures using visible light. Objects that are really
far away won't show up very well in visible light because most of the light
has been red-shifted
then becomes infrared light, which can be seen by the NICMOS. You can
see the relation between visible and infrared in the electromagnetic spectrum
NASA plans to launch the Next Generation Space Telescope (NGST) in 2007.
It will be able to take clearer infrared pictures and hopefully be able
to confirm the distances to far away objects.
