The James Webb Space Telescope reached a mission-readiness landmark today when its first primary mirror segment was cryo-polished to its required prescription as measured at operational cryogenic temperatures. This achievement sets the stage for a successful polishing process for the remaining 18 flight mirror segments. Northrop Grumman Corporation is leading Webb's design and development effort for NASA's Goddard Space Flight Center, Greenbelt, Md. "Many predicted it would take us multiple...

In ancient mythological times reflective surfaces like shiny metals and mirrors were thought to be magical and credited with the ability to look into the future. NASA is using mirrors to do just the opposite "“ look into the past. Fast forward a couple of centuries from ancient time and myths to find NASA is developing a primary mirror, 21.3 feet in diameter, for use on the James Webb Space Telescope in a very different way -- to tell us about our beginning in the universe and how the...

A key tool to unlocking the secrets of the universe will soon be unveiled by Spain on the Canary Islands. It's called the world's biggest scope for visible and infrared light. The Great Canary Telescope (GTC) is as powerful as four million human eyes combined. It promises the ability to look into the darkest and most distant corners of space. Spain's King Juan Carlos will on Friday officially inaugurate the telescope, which cost more than $143 million dollars to build. The observatory helps...

ESO's Very Large Telescope "” Europe's flagship facility for ground-based astronomy "” has been equipped with the first of its second generation instruments: X-shooter. It can record the entire spectrum of a celestial object in one shot "” from the ultraviolet to the near-infrared "” with high sensitivity. This unique new instrument will be particularly useful for the study of distant exploding objects called gamma-ray bursts. "X-shooter offers a capability that is...

The largest-ever gamma-ray telescope is set to collect its "first light" at an opening ceremony on Saturday. Located on the island of Palma, the Major Atmospheric Gamma-ray Imaging Cerenkov Magic II will replace its predecessor, the Magic telescope. When it was built, the first Magic telescope was the largest gamma-ray telescope in the world, until 2003, when the four-telescope High-energy Stereoscopic System (Hess) was unveiled. Now, Magic's successor will reclaim the title once more, but...

An international team of astronomers has used a U.S. radio telescope to study the brightest galaxies that the Fermi Gamma-ray Space Telescope can see. Yuri Kovalev at the Max Planck Institute for Radio Astronomy in Germany said the study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. Kovalev and colleagues used the world's largest radio telescope -- the National Science Foundation's Very Long Baseline Array -- a set of 10 radio...

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...

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".)...

Adaptive Optics -- Adaptive optics is a technology to improve the performance of Earth-based telescopes, reversing the effect of atmospheric distortions. When light from a star or another astronomical object enters the Earth's atmosphere, the different temperature layers and different wind speeds distort and move the image in various ways (see seeing for a proper discussion). The net result is that an 8 meters or 10 meters telescope (like the VLT or Keck), while theoretically capable...

Active Optics -- Active optics is a relatively new technology for astronomic telescopes. Most modern telescopes are reflectors, with the primary element being a very large mirror. Historically, a fixed weight-to-diameter relation was used to build these mirrors, limiting their maximum diameter to 5 or 6 meters (200 or 230 inches), like in the Palomar Observatory. A new generation of telescopes uses instead very thin mirrors, uncapable of sustaining themselves. Instead, an array of...
