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

[ 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...

Image 1 - Vampire Star Reveals Its Secrets
2011-12-07 05:55:54

[ Video 1 ] | [ Video 2 ] Astronomers have obtained the best images ever of a star that has lost most of its material to a vampire companion. By combining the light captured by four telescopes at ESO´s Paranal Observatory they created a virtual telescope 130 meters across with vision 50 times sharper than the NASA/ESA Hubble Space Telescope. Surprisingly, the new results show that the transfer of mass from one star to the other in this double system is gentler than expected....

Image 1 - Astronomers Find Fastest Rotating Star Ever
2011-12-06 09:33:42

ESO's Very Large Telescope has picked up the fastest rotating star found so far. This massive bright young star lies in our neighboring galaxy, the Large Magellanic Cloud, about 160 000 light-years from Earth. Astronomers think that it may have had a violent past and has been ejected from a double star system by its exploding companion. An international team of astronomers has been using ESO´s Very Large Telescope at the Paranal Observatory in Chile, to make a survey of the heaviest...

Image 1 - 'Star Wars' Laser Gives new Insight Into Earth's Atmosphere
2011-11-29 13:41:59

[ Watch the Video ] With the need to understand global change one of today's most pressing scientific challenges, ESA is exploring novel techniques for future space missions. Firing laser pulses between satellites is promising a step up in tracking greenhouse gases. More renowned for their appeal as holiday destinations, the Spanish Canary Islands recently played host to an experiment that involved shooting laser beams from a peak on La Palma to Tenerife. Over the course of two...

Spanish Crown Prince Visits ESO's Paranal Observatory
2011-11-28 11:48:36

On 24 November 2011 ESO´s Paranal Observatory in Chile was honored by a visit from Their Royal Highnesses the Prince and Princess of Asturias. The delegation, which also included the Spanish Minister of Science and Innovation, Dr. Cristina Garmendia, the Chilean Minister of Foreign Affairs, Alfredo Moreno, and the Chilean Minister of National Assets, Catalina Parot, first had the opportunity to hear a series of presentations about ESO at the Paranal Residencia. This session was also...

Image 1 - Assembly Stand Completed for NASA's Webb Telescope Flight Optics
2011-11-17 14:23:26

[ Watch the Video ] The clean room at NASA's Goddard Space Flight Center in Greenbelt, Md., has received a giant structural steel frame that will be used to assemble the mirrors and instruments of the James Webb Space Telescope. "This milestone is important as it marks the transition to the integration and testing phase for the Webb telescope's optical telescope element," said Lee Feinberg, Optical Telescope Element Manager for the Webb telescope at Goddard. The Webb telescope is the...

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".)...
