A new mammoth telescope has begun to inspect the northern sky. The 8-meter Gemini North telescope, pictured above, was dedicated last week in Hawaii, with images documenting its unprecedented abilities being released. Within two years, sister telescope Gemini South will begin similar observations of the southern sky from Chile.
The Galactic Center Across the Infrared
7.07.2002
The center of our Galaxy is obscured in visible light by dark dust that rotates with the stars in the Galactic Plane. In this century, however, sensors have been developed that can detect light more red that humans can see - light called infrared.
The Sloan Digital Sky Survey Telescope
17.06.1998
The Sloan Digital Sky Survey (SDSS) will soon begin. Pictured above is the 2.5-meter telescope poised to create the most ambitious sky map in the history of astronomy. SDSS will catalog one quarter of the sky down past 23rd magnitude ( R), obtaining redshifts for galaxies and quasars brighter than magnitude 19.
Around the World in 80 Telescopes
3.04.2009
Want to go on an extraordinary voyage? Today you can, by watching Around the World in 80 Telescopes. The 24-hour long webcast is organized by the European Southern Observatory for the International Year of Astronomy cornerstone project 100 Hours of Astronomy.
La Silla s Starry Night
23.09.2004
On clear, moonless nights, the stars still come out with a vengance above the high-altitude La Silla astronomical observatory. Taking advantage of a recent visit to this first European Southern Observatory (ESO) site constructed on a mountain top in Chile, ESO software engineer Nico Housen recorded this stunning sky view.
Hawaii

Aloha! With the graceful arc of Earth's limb in the background, the Hawaiian Island archipelago is visible in this stunning photo taken by the astronauts onboard the shuttle Discovery in October of 1988. Along with popular beaches and tropical resorts, these volcanic islands offer extreme elevations with dark, dry, cloudless skies.
100 Hours of Astronomy Begins
2.04.2009
Today, 100 Hours of Astronomy begins, a cornerstone project of the International Year of Astronomy 2009 celebrating the 400th anniversary of Gallileo's original telescopic exploration of the sky. Running from April 2 through...
The 60 inch Reflector
13.12.2008
On the night of December 13, 1908, 100 years ago today, the 60-inch diameter reflecting telescope of Mount Wilson Observatory was first tested on the stars. It became the first successful large reflecting telescope.
Night MAGIC
15.10.2004
Is it magic? On a rare foggy night, mysterious laser beams seem to play across the MAGIC telescope at Roque de los Muchachos on the Canary Island of La Palma. The lasers are actually part of a system designed to automatically adjust the focusing of the inovative, seventeen meter wide, multi-mirrored instrument.
A Year of New Perspectives
28.12.1999
Fittingly, 1999 saw a decade of astronomical discoveries to an end with portents of things to come - embodied in new spacecraft, telescopes, and perspectives to explore the distant Universe across the electromagnetic spectrum. X-ray astronomy in particular will likely flourish in coming
