ESO Celebrates 50 Years Of Reaching New Heights In Astronomy
2012-01-06 07:09:27

The year 2012 marks the 50th anniversary of the European Southern Observatory (ESO), the foremost intergovernmental astronomy organization in the world. The anniversary year is an opportunity to look back at ESO´s history, celebrate its scientific and technological achievements and look forward to its next ambitious programs. ESO is planning several exciting activities during the year. On 5 October 1962, representatives from five European countries – Belgium, France, Germany,...

VLT Image Reveals Omega Nebula's Smoky Pink Core
2012-01-04 10:40:49

[ Watch the Video ] A new image of the Omega Nebula, captured by ESO's Very Large Telescope (VLT), is one of the sharpest of this object ever taken from the ground. It shows the dusty, rose-colored central parts of this famous stellar nursery and reveals extraordinary detail in the cosmic landscape of gas clouds, dust and newborn stars. The colorful gas and dark dust in the Omega Nebula serve as the raw materials for creating the next generation of stars. In this particular section of...

Christmas Comet Lovejoy Captured At Paranal
2011-12-28 04:30:22

[ Watch the Video ] The recently discovered Comet Lovejoy has been captured in stunning photos and time-lapse video taken from ESO´s Paranal Observatory in Chile. The comet graced the southern sky after it had unexpectedly survived a close encounter with the Sun. A new time-lapse video sequence was taken by Gabriel Brammer from ESO less than two days ago on 22 December 2011. Gabriel was finishing his shift as support astronomer at the Paranal Observatory when Comet Lovejoy rose...

Cryogenic Testing Completed For Webb Telescope Mirrors
2011-12-22 04:39:44

Cryogenic testing is complete for the final six primary mirror segments and a secondary mirror that will fly on NASA's James Webb Space Telescope. The milestone represents the successful culmination of a process that took years and broke new ground in manufacturing and testing large mirrors. "The mirror completion means we can build a large, deployable telescope for space," said Scott Willoughby, vice president and Webb program manager at Northrop Grumman Aerospace Systems. "We have proven...

The Porter Garden Telescope, a magnificent garden sculpture and optically superb instrument, is cast in bronze and bears a hand...

Image 1 - Webb Telescope Receives COCOA This Winter
2011-12-16 09:14:50

Engineers working on NASA's James Webb Space Telescope are bringing out the COCOA this winter, but it's not a warm beverage. Rather, it's a way to check that the mirrors are perfectly shaped and will work in the frosty environment of space. COCOA stands for "Center of Curvature Optical Assembly." Curvature is important in a mirror, just as the convex side mirrors on your car are shaped to give you a wide field of vision behind and beside your car. COCOA tests on the Webb telescope's...

[ Watch the Video ] VLT Survey Telescope snaps wide-field view of NGC 253 The VLT Survey Telescope (VST) has captured the beauty of the nearby spiral galaxy NGC 253. The new portrait is probably the most detailed wide-field view of this object and its surroundings ever taken. It demonstrates that the VST, the newest telescope at ESO's Paranal Observatory, provides broad views of the sky while also offering impressive image sharpness. NGC 253 gleams about eleven and a half million...

Image 1 - E-ELT Moves Closer To Reality
2011-12-09 10:21:32

[ Video 1 ] | [ Video 2 ] The governing body of the European Southern Observatory, the ESO Council, has approved ESO´s budget for 2012. This includes preparatory work on the road to the European Extremely Large Telescope (E-ELT) site at Cerro Armazones and the start of development of some very challenging optical components for the telescope. With several ESO Member States now having committed their part of the required additional funding, the final approval for the whole E-ELT...

Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...

A telescope, designed to aid the observation of remote objects, collects some form of electromagnetic radiation (such as visible light). The Netherlands developed the first known practical telescope in the 17th century. The term "telescope" was termed in order to describe Galileo's instruments in 1611. However, Galileo was not the inventor of the telescope. It was Hans Lippershey, Zacharias Janssen, and Jacob Metius who are credited with the creation of the telescope. In 1668, Isaac Newton...

The Reverend Thomas William Webb (December 14, 1807 "“ May 19, 1885) was a British astronomer and faithful clergyman. The lone son of a clergyman, the Rev. John Webb was raised and educated by his father in absence of his mother who died in Webb's early childhood. He travelled to Oxford to attend Magdalen College. Soon after, he was ordained a minister by the Anglican Church in 1829. In 1843, he married Henrietta Montague. Mrs. Webb died on September 7, 1884. Webb followed shortly...

Very Large Telescope -- The Very Large Telescope (VLT) consist of four optical telescopes that have 8.4 meter aperture. The VLT is a project of the European Southern Observatory organization. It is located at the Paranal Observatory on Cerro Paranal, a 2,635-m high mountain in the Atacama desert in northern Chile. The VLT consists of a cluster four of large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the...

Telescope -- A telescope is an instrument composed of one or more lenses or mirrors to gather and focus electromagnetic radiation. Telescopes increase the observed angular size of objects, as well as their apparent brightness. The largest telescopes are used in astronomy. A telescope was first turned on the sky by Galileo Galilei, the Italian scientist. (Telescopes used for non-astronomical purposes may be called "transits," "monoculars," "binoculars," "camera lenses," or "spyglasses".)...
