IRTF: Scanning the Infrared Skies
			
		
		
		
			Above, NASA's Infrared Telescope Facility (IRTF) poses in front of a starry
background.  Located on top of 
Hawaii's towering 
volcano 
Mauna Kea, the
IRTF 
is the premier telescope for observing in near 
infrared light. This
3-meter telescope was established in 1979 and spends about half its time
observing 
Solar System 
objects.  In 1994, for example, the 
IRTF recorded
pieces of the famous comet 
Shoemaker-Levy 9 plunge into 
Jupiter.  Last year, the 
IRTF 
recorded 
an outburst of a volcano on Jupiter's moon 
Io.
IRTF's 
observational successes outside our Solar System include
understanding the infrared emission of 
dust and 
Pre-Main 
Sequence stars and even the
identification 
of faint galaxies.
