|"In this unusual image, NASA’s Hubble Space Telescope captures a rare view of the celestial equivalent of a geode -- a gas cavity carved by the stellar wind and intense ultraviolet radiation from a hot young star. Real geodes are baseball-sized, hollow rocks that start out as bubbles in volcanic or sedimentary rock. Only when these inconspicuous round rocks are split in half by a geologist...||01/10/2009||906|
|This Hubble telescope image shows one of the most complex planetary nebulae ever seen, NGC 6543, nicknamed the "Cat's Eye Nebula." Hubble reveals surprisingly intricate structures including concentric gas shells, jets of high-speed gas, and unusual shock-induced knots of gas. Estimated to be 1,000 years old, the nebula is a visual "fossil record" of the dynamics and late evo...||01/10/2009||580|
|The Hubble telescope has snapped this remarkable view of a perfectly "edge-on" galaxy, NGC 4013. This new Hubble picture reveals with exquisite detail huge clouds of dust and gas extending along, as well as far above, the galaxy's main disk. NGC 4013 is a spiral galaxy, similar to our Milky Way, lying some 55 million light-years from Earth in the direction of the constellation Ursa Ma...||01/10/2009||1,114|
|There are 13 telescopes here (including Keck the world's largest). Their combined light gathering power is 60 times greater than the Hubble Space Telescope. Our mystery mountain is known for another kind of light. It once was a fiery volcano, but don't worry, it hasn't erupted for at least four-thousand years.|
|Astrophysical Observatory of the Russian Academy of Sciences.|
The BTA-6 has a prime mirror diameter of 6 m and is housed in a 48 m diameter dome at an altitude of 2,070 m. Seeing first light in late 1975, it held the record for the largest telescope in the world from its completion until 1993 when it was surpassed by the Keck 1 telescope in Hawaii.
|"A rare and spectacular head-on collision between two galaxies appears in this Hubble telescope picture of the Cartwheel Galaxy, located 500 million light-years from Earth in the constellation Sculptor."|
|Cerro Paranal, a 2,635 m high mountain in the Atacama desert in northern Chile, famous for hosting the Very Large Telescope (VLT) and the VLT Survey Telescope (VST). It is located 120 km south of Antofagasta and 80 km north of Tal-Tal, 12 km inland. Coordinates 24° 37′ 38″ S 70° 24′ 17″ W.||08/03/2005||791|
|During the middle of the 19th century the Government of Victoria voted the sum of £5000 for the construction of a large equatorial telescope to be erected at the Melbourne Observatory, Australia.|
The construction of the grand instrument was entrusted to Mr.Grubb, F.R.S., of Dublin, Ireland. At the commencement of the year 1868 the telescope was completed.
The Great Melbourne teles...
|Representing a narrow "keyhole" view stretching to the visible horizon of the universe, the Hubble Deep Field image covers a speck of the sky only about the width of a dime 75 feet away. Though the field is a very small sample of the heavens, it is considered representative of the typical distribution of galaxies in space, because the universe, statistically, looks largely the same in...||01/10/2009||624|
|A 17-story Millimetre Radio telescope being assembled atop of the 15,000-foot La Negra dormant volcano. |
It will probe the origins of the universe with an antenna dish the size of a baseball infield.
The Large Millimetre Telescope is a bi-national project sponsored by both U.S. and Mexican governments and institutions to build the largest single-dish millimetre-wavelength radio t...
|The Westerbork Synthesis Radio Telescope (WSRT) (near camp Westerbork, north of the village of Westerbork, Midden-Drenthe, in the northeastern Netherlands) is an aperture synthesis interferometer that consists of a linear array of 14 antennas arranged on a 2.7 km East-West line. It has a similar arrangement to other radio telescopes such as the One-Mile Telescope and the Ryle Telescope. Ten of ...||11/17/2005||552|
|Lowell Observatory is an astronomical observatory near Flagstaff, Arizona. It was founded in 1894 by astronomer Percival Lowell.|
The observatory operates several telescopes at two locations in Flagstaff. The main facility, located on Mars Hill just west of downtown Flagstaff, houses the original 24-inch (.61-metre) Clark Refracting Telescope.
The telescope is listed as a US nation...
