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...

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...

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...

APEX Provides New View Of Carina Nebula Star Formation
2011-11-16 10:11:45

[ Watch the Video ] Observations made with the APEX telescope in submillimeter-wavelength light reveal the cold dusty clouds from which stars form in the Carina Nebula. This site of violent star formation, which plays host to some of the highest-mass stars in our galaxy, is an ideal arena in which to study the interactions between these young stars and their parent molecular clouds. Using the LABOCA camera on the Atacama Pathfinder Experiment (APEX) telescope on the plateau of...

Image 1 - VISTA Finds New Globular Star Clusters
2011-10-19 08:33:07

Sees right through the heart of the Milky Way [ Watch Video 1 ] | [ Watch Video 2 ] Two newly discovered globular clusters have been added to the total of just 158 known globular clusters in our Milky Way. They were found in new images from ESO´s VISTA survey telescope as part of the Via Lactea (VVV) survey. This survey has also turned up the first star cluster that is far beyond the center of the Milky Way and whose light has had to travel right through the dust and gas in the...

Image 1 - ESO: Full-size Mock-up Of World’s Largest Telescope Mirror
2011-10-17 08:51:37

[ Watch Video 1 ] | [ Watch Video 2 ] On Saturday 15 October, the European Southern Observatory (ESO) opened the doors of its headquarters in Garching bei München, Bavaria, Germany, to the public. Throughout the day, thousands of visitors had the chance to help build a full-size mock-up mirror of the largest planned telescope in the world – the European Extremely Large Telescope (E-ELT) – and to experience many other aspects of ESO´s work. Around 3100...

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".)...
