| | NASA Releases Rare Pictures From a Fourth Space Observatory |
 | | The observatory, known as the Space Infrared Telescope Facility when launched on Aug. 25, was renamed on Thursday in honor of Dr. Lyman Spitzer Jr., the famed Princeton astronomer who in 1946 first proposed launching telescopes into space, to avoid the obscuring effects of Earth's atmosphere. |
 | | The Great Observatory series, conceived in the 1980's, also includes the Hubble Space Telescope, launched in 1990; the Compton Gamma Ray Observatory, launched in 1991 and decommissioned in 1999; and the Chandra X-Ray Observatory, orbited in 1999. |
 | | The Spitzer Space Telescope is able to detect the faint warmth of cool, distant objects by keeping its instruments extremely cold so that they are supersensitive. |
