NASA is preparing to launch its next Great Observatory in 2002, but it does not yet have a proper name. Can you help? Currently referred to only as the Space Infrared Telescope Facility (SIRTF), NASA seeks to add something more significant.
Paranal Moonset
4.11.2006
Just before the rising Sun fully illuminated the 2,635 meter summit of Cerro Paranal in northern Chile, Gordon Gillet captured this stunning moonset. In the telephoto picture, a nearly full October Moon is silhouetting the impressive array of telescopes at ESO's Paranal Observatory.
Hubble Floats Free
25.05.2009
Why put observatories in space? Most telescopes are on the ground. On the ground, you can deploy a heavier telescope and fix it more easily. The trouble is that Earth-bound telescopes must look through the Earth's atmosphere.
CFHT Star Trails
5.09.2000
High atop a dormant volcano in Hawaii, an eye 3.6-meters wide stares at a faint light on the night sky. Unlike a human eye, which collects light for only a fraction of a second at a time, a telescope such as the Canada-France-Hawaii Telescope (CFHT) can collect light for hours.
Neptune through Adaptive Optics
18.02.2000
From the Earth's surface, Neptune usually appears as a fuzzy blotch. The blurring effects of the Earth's atmosphere deny clearer images. By distorting mirrors in the telescope itself in time with the changing atmosphere, however, these effects can be greatly reduced.
3 ATs
4.05.2024
Despite their resemblance to R2D2, these three are not the droids you're looking for. Instead, the enclosures house 1.8 meter Auxiliary Telescopes (ATs) at Paranal Observatory in the Atacama Desert region of Chile.
The Cat's Eye Nebula
28.06.1995
Three thousand light years away, a dying star throws off shells of glowing gas. This Hubble Space Telescope image reveals "The Cat's Eye Nebula" to be one of the most complex "planetary nebulae" known.
Space Walz
11.02.1997
Astronaut Carl Walz waves at his colleagues from the aft end of the Space Shuttle Discovery's payload bay - during a 1993 spacewalk to evaluate tools, tethers, and a foot restraint slated for use in the first Hubble Space Telescope servicing mission.
The Milky Way in Infrared
29.12.1997
At night, from a dark location, part of the clear sky looks milky. This unusual swath of dim light is generally visible during any month and from any location. Until the invention of the telescope, nobody really knew what the "Milky Way" was.
Kitt Peak National Observatory
18.01.1999
At the top of Kitt Peak Mountain near Tucson, Arizona lies one of the world's great collections of telescopes. As pictured, in the dome at the far left lies the 3.5-meter WIYN Telescope, famous recently for tracking distant supernovae.
