Tiny Planet-Finding Mirrors Borrow From Webb's Playbook
2012-05-25 03:33:19

NASA's next flagship mission – the James Webb Space Telescope – will carry the largest primary mirror ever deployed. This segmented behemoth will unfold to 21.3 feet in diameter once the observatory reaches its orbit in 2018. A team of scientists at NASA's Goddard Space Flight Center in Greenbelt, Md., now is developing an instrument that would image and characterize planets beyond the solar system possibly from a high-altitude balloon has borrowed a page from the Webb...

New imaging spectrograph eliminates aberrations present in existing instruments. Trenton, New Jersey (PRWEB) May 21, 2012 Princeton Instruments is pleased to introduce the IsoPlane SCT-320,The IsoPlane (patent pending) features a revolutionary new optical design that eliminates the primary aberrations present in traditional imaging spectrographs. It produces images that are clearer and sharper across the focal plane than any comparable spectrograph on the market. As a result, more photons...

Astrophysicists Use Three-Telescope Interferometry To Observe How Black Holes Are Fueled
2012-05-18 03:45:33

By combining the light of three powerful infrared telescopes, an international research team has observed the active accretion phase of a supermassive black hole in the center of a galaxy tens of millions of light years away, a method that has yielded an unprecedented amount of data for such observations. The resolution at which they were able to observe this highly luminescent active galactic nucleus (AGN) has given them direct confirmation of how mass accretes onto black holes in centers of...

ESO Takes A Deeper Look At Centaurus A Galaxy
2012-05-16 14:17:14

[ Video 1 ] | [ Video 2 ] The strange galaxy Centaurus A is pictured in a new image from the European Southern Observatory (ESO). With a total exposure time of more than 50 hours this is probably the deepest view of this peculiar and spectacular object ever created. The image was produced by the Wide Field Imager of the MPG/ESO 2.2-meter telescope at ESO´s La Silla Observatory in Chile. Centaurus A, also known as NGC 5128 [1], is a peculiar massive elliptical galaxy with a...

ESA Teaming Up With Amateur Astronomers To Spot Near Earth Objects
2012-05-14 11:01:47

Lee Rannals for RedOrbit.com The European Space Agency (ESA) is reaching out to amateur astronomers, asking for their help in discovering potentially dangerous space rocks. ESA's Space Situational Awareness (SSA) program helps keep up with space hazards, with everything from space weather to debris objects in Earth orbit. The program also keeps up with "Near Earth objects," or NEOs, which are asteroids that pass close enough to our planet to cause concern. NEOs are hard to survey...

Messier 55's Vast Ball Of Stars Imaged By ESO's VISTA
2012-05-09 10:53:23

[ Video 1 ] | [ Video 2 ] A new image of Messier 55 from ESO's VISTA infrared survey telescope shows tens of thousands of stars crowded together like a swarm of bees. Besides being packed into a relatively small space, these stars are also among the oldest in the Universe. Astronomers study Messier 55 and other ancient objects like it, called globular clusters, to learn how galaxies evolve and stars age. Globular clusters are held together in a tight spherical shape by gravity. In...

APEX Captures Stunning Image Of Dust Near Orion's Belt
2012-05-02 12:52:36

[ Video 1 ] | [ Video 2 ] A new image of the region surrounding the reflection nebula Messier 78, just to the north of Orion´s Belt, shows clouds of cosmic dust threaded through the nebula like a string of pearls. The observations, made with the Atacama Pathfinder Experiment (APEX) telescope[1], use the heat glow of interstellar dust grains to show astronomers where new stars are being formed. Dust may sound boring and uninteresting – the surface grime that hides the beauty...

3.4 Billion Pixel Telescope Plans Move One Step Further
2012-04-26 13:11:13

Lee Rannals for RedOrbit.com The U.S. Department of Energy has given the go ahead for a proposed 3.4 billion pixel Large Synoptic Survey Telescope (LSST) to move on to the next step of development. Now that the project has received approval from the department, it will begin the engineering design, scheduling, and budgeting portion of the project. The telescope received a "Critical Decision 1" approval, making a big step toward being one of the widest, fastest and deepest view...

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".)...
