ESO's Very Large Telescope captured this striking view of the nebula around the star cluster NGC 1929 within the Large Magellanic Cloud, a satellite galaxy of our own Milky Way. A colossal example of what astronomers call a superbubble dominates this stellar nursery. It is being carved by the winds from bright young stars and the shockwaves from supernova explosions. The Large Magellanic Cloud is a small neighboring galaxy to the Milky Way. It contains many regions where clouds of gas and...

A Russian radio telescope intended to be the largest of its kind in space, has started its stellar orbit around planet Earth for the first time since being launched, reports BBC News. The radio telescope, named RadioAstron, part of the Russian space observatory -- Spectrum-R -- will travel in an elliptical orbit that at its farthest point from Earth will take it close to the Moon. It was carried into orbit by the Zenith-3M rocket, taking off from Kazakhstan's Baikonur Cosmodrome on Monday...

GREENBELT, Md., July 19, 2011 /PRNewswire-USNewswire/ -- "Secondary" may not sound as important as "primary" but when it comes to the next-generation James Webb Space Telescope a secondary mirror plays a critical role in ensuring the telescope gathers information from the cosmos. The Webb's secondary mirror was recently completed, following polishing and gold-coating. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) There are four different types of mirrors that will fly on...

The discovery potential of the future international SKA radio telescope has been glimpsed following the commissioning of a working optical fibre link between CSIRO's Australian SKA Pathfinder (ASKAP) telescope in Western Australia, and other radio telescopes across Australia and New Zealand. The achievement will be announced at the 2011 International SKA Forum, taking place this week in Banff, Canada. On 29 June, six telescopes "“ ASKAP, three CSIRO telescopes in New South Wales, a...

Molecules of hydrogen peroxide have been found for the first time in interstellar space. The discovery gives clues about the chemical link between two molecules critical for life: water and oxygen. On Earth, hydrogen peroxide plays a key role in the chemistry of water and ozone in our planet's atmosphere, and is familiar for its use as a disinfectant or to bleach hair blonde. Now it has been detected in space by astronomers using the ESO-operated APEX telescope in Chile. An international team...

Mirrors are a critical part of a telescope. The quality is crucial, so completion of mirror polishing represents a major milestone. All of the mirrors that will fly aboard NASA's James Webb Space Telescope have been polished so the observatory can see objects as far away as the first galaxies in the universe. The Webb telescope is comprised of four types of mirrors. The primary one has an area of approximately 25 square meters (29.9 square yards), which will enable scientists to capture light...

By Daniel Stolte, University of Arizona When finished, the 4.2-meter mirror will be the largest telescope mirror ever pointed at the sun. Polished into a highly complex, asymmetric shape, it will be the centerpiece of the Advanced Technology Solar Telescope in Hawaii, allowing researchers to study the sun in unprecedented detail. The University of Arizona's College of Optical Sciences has been awarded a multi-million dollar contract by the Association of Universities for Research in...

New image reveals vast nebula around famous supergiant star Using the VISIR instrument on ESO's Very Large Telescope (VLT), astronomers have imaged a complex and bright nebula around the supergiant star Betelgeuse in greater detail than ever before. This structure, which resembles flames emanating from the star, is formed as the behemoth sheds its material into space. Betelgeuse, a red supergiant in the constellation of Orion, is one of the brightest stars in the night sky. It is also one of...

The James Webb Space Telescope completes first round of cryogenic mirror test The first six of 18 segments that will form NASA's James Webb Space Telescope's primary mirror for space observations completed final cryogenic testing on Friday. The ten week test series included two tests cycles where the mirrors were chilled down to -379 degrees Fahrenheit, then back to ambient temperature to ensure the mirrors respond as expected to the extreme temperatures of space. A second set of six mirror...

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...

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".)...
