A new theory to explain the high-energy gamma-ray emissions from collapsing stars has been put forward by an international team of researchers. Their results will be published shortly in the Monthly Notices of the RAS. Long duration gamma-ray bursts (GRBs), first discovered in the 1970s, are the most explosive events in the Universe. Finding out what happens during these cataclysmic events is a major challenge, partly because they usually occur at the edge of the visible Universe and partly...

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...

PSU -- It came from the edge of the visible universe, the most distant explosion ever detected. In this week's issue of Nature, scientists at Penn State University and their U.S. and European colleagues discuss how this explosion, detected on 4 September 2005, was the result of a massive star collapsing into a black hole. The explosion, called a gamma-ray burst, comes from an era soon after stars and galaxies first formed, about 500 million to 1 billion years after the Big Bang. The...

NASA -- Scientists using NASA's Swift satellite have detected a new kind of cosmic explosion. The event appears to be a precursor to a supernova, which is expected to reach peak brightness in about a week's time. UK astronomers and their colleagues around the world are watching closely as they have never seen an explosion of this kind before. Satellites and the world's largest telescopes are now trained on the sight, watching and waiting. The explosion has the trappings of a gamma-ray burst...

PPARC -- In a recent issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists reports the discovery of another new type of very high energy (VHE) gamma ray source. Gamma-rays are produced in extreme cosmic particle accelerators such as supernova explosions and provide a unique view of the high energy processes at work in the Milky Way. VHE gamma-ray astronomy is still a young field and H.E.S.S. is conducting the first sensitive survey at...

PPARC --  In the March 25th 2005 issue of Science Magazine, the High Energy Stereoscopic System (H.E.S.S.) team of international astrophysicists, including UK astronomers from the University of Durham, report results of a first sensitive survey of the central part of our galaxy in very high energy (VHE) gamma-rays. Included among the new objects discovered are two 'dark accelerators' - mysterious objects that are emitting energetic particles, yet apparently have no optical or x-ray...

The SETI Institute predicts that we'll detect an extraterrestrial transmission within twenty years. Within a year, the first thirty dishes of a huge telescope array will be operational, forming the basis of a giant ear that listens for intelligent beings in space while simultaneously gathering data for groundbreaking astronomy research. Astrobiology Magazine -- The SETI Institute predicts that we'll detect an extraterrestrial transmission within twenty years. If that turns out to be true,...

NASA -- The NASA-led Swift mission has opened its doors to a flurry of gamma-ray burst action. Scientists were still calibrating the main instrument, the Burst Alert Telescope (BAT), when the first burst appeared on December 17. Three bursts on December 19, and one on December 20, followed. Swift's primary goal is to unravel the mystery of gamma ray bursts. The bursts are random and fleeting explosions, second only to the Big Bang in total energy output. Gamma rays are a type of light...

PARIS (AFP) -- Libya has ordered a 13-million-dollar telescope from France, a facility that will give it the finest astronomical views in North Africa, the French magazine Ciel et Espace (Sky and Space) reported. The telescope, costing nearly 10 million euros, was ordered by Libyan leader Moamer Kadhafi, who has a passionate interest in astronomy, the monthly said in its January issue. Built by Sagem, a French electronics group, the telescope will be two metres (6.5 feet) diameter and...

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...
