A team of internationally renowned astronomers and opticians may have found a way to make "unbelievably large" telescopes on the Moon. "It's so simple," says Ermanno F. Borra, physics professor at the Optics Laboratory of Laval University in Quebec, Canada. "Isaac Newton knew that any liquid, if put into a shallow container and set spinning, naturally assumes a parabolic shape"”the same shape needed by a telescope mirror to bring starlight to a focus. This could be the key to making a...

After 3 years and $10,000 worth of restoration costs, Albert Einstein's long-lost telescope will be put on display at the Hebrew University in Jerusalem, an institution the theorist helped start. The old reflecting telescope is bulky, but is still powerful enough to see Jupiter's rings and it's five moons. Einstein received the telescope in 1954, one year before he died, as a gift from a friend named Zvi Gizeri.  Officials at the university believe Gizeri may have made the telescope...

New historical evidence suggests the telescope may have been invented in Spain, not the Netherlands or Italy as scientists once thought. The findings suggest the telescope's creator could have been a spectacle-maker based in Gerona, Spain. The first refracting telescopes were thought to have appeared in the Netherlands in 1608 and may actually have been made for Spanish merchants. According to historian Nick Pelling, the inventor could have been a man called Juan Roget, who died between 1617...

Glasses embedded with a telescope promise to make it easier for people with impaired vision to drive and do other activities requiring sharper distance vision. Schepens Eye Research Institute scientists describe the advantages of these innovative glasses over earlier devices in an article published in the May/June issue of Journal of Biomedical Optics, mailed in print form to subscribers this month. "This new design has several advantages," says the inventor of the glasses, Dr. Eli Peli, who...

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...

A new space mission, due to launch this month, is going to shed light on some of the most extreme astrophysical processes in nature - including pulsars, remnants of supernovae, and supermassive black holes. It could even help us comprehend the origin and distribution of dark matter, write three scientists currently preparing for the GLAST mission from NASA's Goddard Space Flight Centre in Greenbelt, Maryland, USA, in this month's Physics World. The Gamma-Ray Large Area Space Telescope...

Images from NASA telescopes are jewels of the space program, marvelous to behold. But how do you behold them when you can't see? The answer lies between the covers of a new NASA-funded book written in Braille, Touch the Invisible Sky. In an inspiring forward to the volume, blind mountain climber Erik Weihenmayer writes, "Sight ... is only one of the many tools with which to experience the marvels of the world." Touch the Invisible Sky uses Braille, large type print, and tactile diagrams of...

Microsoft co-founder Paul Allen paid for half of a new telescope facility in California, a $50 million array to find other civilizations in the universe. The Seattle Times said the telescope is the first major telescope dedicated to finding life in the heavens. Allen was set to join scientists from SETI -- the Search for Extraterrestrial Intelligence -- to unveil the Allen Telescope Array this week. The 42 radio dishes are perched on a plateau 300 miles northeast of San Francisco The...

A whole new world came to life for Alice when she passed through the looking glass "“ beetles with bad attitudes, Tweedledee and Tweedledum, smiling cats, talking tiger lilies and much more. Mirrors have special powers in the real world too, especially in the hands of an astronomer. In fact, modern astronomy depends on mirrors. Almost every telescope uses a mirror, sometimes several mirrors, to gather and guide starlight toward some super-sensitive digital detector where a breathtaking...

LABOCA in Service at APEX The world's largest bolometer camera for submillimetre astronomy is now in service at the 12-m APEX telescope, located on the 5100m high Chajnantor plateau in the Chilean Andes. LABOCA was specifically designed for the study of extremely cold astronomical objects and, with its large field of view and very "A large fraction of all the gas in the Universe has extremely cold temperatures of around minus 250 degrees Celsius, a mere 20 degrees above absolute zero," says...

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...

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".)...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...

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...
