Scientists working at NASA's Goddard Space Flight Center in Greenbelt, Md., have concocted an innovative recipe for giant telescope mirrors on the Moon. To make a mirror that dwarfs anything on Earth, just take a little bit of carbon, throw in some epoxy, and add lots of lunar dust."We could make huge telescopes on the moon relatively easily, and avoid the large expense of transporting a large mirror from Earth," says Peter Chen of NASA Goddard and the Catholic University of America, which is...

The road to the Marshall Space Flight Center is mighty dark at 3:30 a.m. There are no streetlights or buildings along this long stretch of rural highway. Only the gleaming eyes of raccoons and skunks peer out from among thick-set pines. Once you get to the Marshall complex, the buildings are all dark too, except for one -- the X-Ray Calibration Facility (XRCF). Here, the lights are on all night and someone is home. Barry Hale (lead technician) and Jay Carpenter (facility engineer) are working...

CHICAGO -- Like cell phones or the Internet in recent history, the telescope's introduction in the early 17th Century had a swift and lasting impact on the world. Telescopes revolutionized military strategy and within months showed the father of astronomy, Galileo Galilei, that Earth is not the center of the universe. Until recently, scholars thought only 8 or 10 of these important early telescopes _ made between 1608 and 1650 of tightly rolled paper and crudely ground lenses _ had...

By Toni Clarke BOSTON -- A Massachusetts observatory unveiled a powerful new telescope on Tuesday designed to capture possible light signals transmitted to Earth by extraterrestrials. The telescope is the first to be developed solely to search the skies for light pulses from aliens and will be able to cover 100,000 times the amount of sky covered by current equipment, its developers said. "The opening of this telescope represents one of those rare moments in a field of scientific endeavor...

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".)...

Parabolic Mirror -- A parabolic reflector or parabolic dish is a reflective device formed in the shape of a paraboloid of revolution. Parabolic reflectors can either collect or distribute energy such as light, sound, or radio waves. The parabolic reflector functions due to the geometric properties of the paraboloid shape: if the angle of incidence to the inner surface of the collector equals the angle of reflection, then any incoming ray that is parallel to the axis of the dish will be...

Amateur Astronomy -- Amateur astronomy, also called backyard astronomy, is a hobby whose participants enjoy watching the night sky (and the day sky too, for sunspots, eclipses, etc.), and the plethora of objects found in it, mainly with portable telescopes and binoculars. Even though scientific research is not their main goal, many amateur astronomers make a contribution to astronomy by monitoring variable stars, tracking asteroids and discovering transient objects, such as comets. Such...
