British amateur astronomers say they have a new challenge -- spotting an astronaut's lost tool bag orbiting the Earth, to be visible until early next month. The backpack-sized object was lost by astronaut Heidemarie Stefanyshyn-Piper during a space walk last week and should be visible from Britain with a reasonably strong telescope or pair of binoculars through the first days of December, astronomers told The Times of London. The best opportunities for British stargazers to spot the tool bag,...

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.

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.

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.

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.

Brian Ramsey and colleagues have built an extraordinary sideways mirror that can harvest high-energy X-rays (also called "hard" X-rays)." It's called a grazing incidence mirror," explains Ramsey, who is HERO's lead scientist, "and it can guide very energetic X-rays."

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...
