The first six of 18 segments that will form NASA's James Webb Space Telescope's primary mirror for space observations will begin final round-the-clock cryogenic testing this week.
It takes two unique types of mirrors working together to see farther back in time and space than ever before, and engineers at NASA's Goddard Space Flight Center have just received one of each type.
This image of the nebula NGC 3582 shows giant loops of gas bearing a striking resemblance to solar prominences.
The ESO Paranal Observatory was honored with a visit from the President of the Czech Republic, VÃ¡clav Klaus.
The Stratospheric Observatory for Infrared Astronomy, or SOFIA, completed its first science flight Wednesday, April 6, using the German Receiver for Astronomy at Terahertz Frequencies (GREAT) scientific instrument.
Many amateur astronomers point their Orion telescopes towards the International Space Station every night. Earlier this month, British astronomer Martin Lewis took numerous images of the International Space Station using his home made telescope and a web cam.
Observations with the European Southern Observatoryâ€™s Very Large Telescope, along with two other telescopes, have shown that there is a new candidate for the coldest known star: a brown dwarf in a double system with about the same temperature as a freshly made cup of tea â€” hot in human terms, but extraordinarily cold for the surface of a star.
A new image from ESOâ€™s Very Large Telescope gives a close-up view of the dramatic effects new-born stars have on the gas and dust from which they formed.
Astronomers have used an armada of telescopes on the ground and in space, including the Very Large Telescope at ESOâ€™s Paranal Observatory in Chile to discover and measure the distance to the most remote mature cluster of galaxies yet found.
Using a perfectly orchestrated world-wide network of radio telescopes, astronomers have produced a high-resolution map of an Active Galactic Nucleus (AGN) belonging to an unknown class of gamma-ray sources.
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".)...
