John P. Millis, Ph.D. for redOrbit.com — Your Universe Online Astronomy is more than merely using optical telescopes to take pretty pictures of distant nebulae and galaxies. Researchers also seek to understand complex systems in the universe by observing how objects interact and what types of radiation are produced. To do this requires telescopes capable of observing over several energy bands, working together to construct a complete physical picture of the object of interest....

SKA Organization Headquarters Opening Ceremony Paves The Way For World’s Largest Radio Telescope
2013-05-07 13:52:09

Square Kilometre Array Less than a year after the decision to site the revolutionary Square Kilometre Array (SKA) in both Southern Africa and Australia, the SKA Organisation has opened its new international headquarters. In front of an invited audience of local and global dignitaries, scientists and engineers, the UK Minister for Universities and Science the Rt. Hon. David Willetts MP recently opened the building which will be home to the team managing the construction, design and...

Students Use Radio Telescope To Explore The Universe
2012-12-10 21:36:49

National Radio Astronomy Observatory A new program is giving middle-school-aged youth the chance to take remote control of a large, research-grade radio telescope and expand their cosmic explorations beyond what the eye can see. The National Radio Astronomy Observatory's (NRAO) 20-meter-diameter telescope in Green Bank, West Virginia, is joining a global network of telescopes bringing the excitement of hands-on research to young people via 4-H, the nation's largest youth development...

Starlight Measured In Detail By Fermi
2012-11-01 13:50:08

[ Watch the Video: NASA's Fermi Explores the Early Universe ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have made the most accurate measurement of starlight in the universe and have used this to establish the total amount of light from all of the stars that have ever shone. A team used data from NASA's Fermi Gamma-Ray Space Telescope to find the total sum of starlight in the universe, or the extragalactic background light (EBL). Gamma rays are the most...

Australia Unveils ASKAP Telescope
2012-10-05 21:32:55

Lee Rannals for redOrbit.com — Your Universe Online Australia has unveiled a new $155 million telescope that could start to capture radio images as soon as today. The Australian Square Kilometer Array Pathfinder (ASKAP) is one of the world's fastest telescopes and sits in Australia's outback. ASKAP has 36 antennas with a diameter of 40 feet each and forms part of the world's biggest radio telescope projects. The telescope is located at the Murchison Radio-Astronomy...

The 'FLOYDS' Spectrographs Acquire Target Robotically At Las Cumbres Observatory
2012-08-29 09:25:08

Two identical FLOYDS spectrographs, installed in recent weeks at telescopes 6,000 miles apart, robotically acquired a supernovae target this week. Due to the level of precision required and the difficulty involved, few if any, other ground-based spectrographs have ever achieved this milestone. “This is unprecedented,” staff astronomer David Sand explained. “In a matter of just a few weeks, Las Cumbres Observatory was able to install the spectrographs, achieve first light,...

Spacetime Is Smooth, Not Foamy
2012-08-24 12:21:41

April Flowers for redOrbit.com - Your Universe Online Scientists have long believed that spacetime is foamy, like a freshly pulled draft beer, but new information from an intergalactic photo finish shows it might just be as smooth as a single malt whiskey, instead. Robert Nemiroff, a physicist at Michigan Technological University, reached this conclusion after studying the tracings of three photons of differing wavelengths that had been recorded by NASA's Fermi Gamma-ray Space Telescope...

Image 1 - Webb Telescope Flight Backplane Section Completed
2012-04-25 01:00:06

The center section of the backplane structure that will fly on NASA's James Webb Space Telescope has been completed, marking an important milestone in the telescope's hardware development. The backplane will support the telescope's beryllium mirrors, instruments, thermal control systems and other hardware throughout its mission. "Completing the center section of the backplane is an important step in completing the sophisticated telescope structure," said Lee Feinberg, optical telescope...

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...
