Ground Telescopes

Subaru Telescope

Since 2000, the National Astronomical Observatory of Japan (NAOJ) has been operating one of the largest and most sophisticated telescopes in the world at the summit of Mauna Kea in Hawaii. The Subaru telescope saw first-light (i.e. started observing) early in 1999 and is currently conducting routine research. Along with other observatories around the world, is making many important discoveries about the Universe we live in.


Keck Telescope

The most powerful telescope on the summit on Mauna Kea is the twin Keck observatory, which has two 10 metre diameter mirrors. At the heart of each Keck Telescope is a revolutionary primary mirror made up of 36 hexagonal segments that effectively work as a single piece of reflective glass. By combining advanced optical and infrared detectors with sophisticated electronics that can combine collected light from both telescopes, the Keck observatory remains amongst the leading astronomical facilities in the world.


Gemini North Telescope

The Gemini project is a multi-national partnership of seven countries that has resulted in two identical 8.1 metre telescopes - one on Hawaii's Mauna Kea mountain (Gemini North) and the other on central Chile's Cerro Pachon mountain (Gemini South). As well as the United Kingdom, the others partners in the project are the United States, Canada, Chile, Australia, Brazil and Argentina.


MMT

The 6.5 metre Multiple Mirror Telescope (MMT) is a joint venture between the Smithsonian Institution and the University of Arizona. The MMT is located on the summit of Mt. Hopkins, the second highest peak in the Santa Rita Range, approximately 55 kilometres (30 miles) south of Tucson, Arizona.


GranTeCan Telescope

The Gran Telescopio Canarias, also known as GranTeCan or GTC, is a 10.4 metre telescope, which began operations in 2009. The GTC Project is a partnership between Spain, Mexico, the University of Florida and the Instituto de Astrofísica de Canarias (IAC).
