ALMA Correlator Supercomputer Turns Man Antennas Into One Giant Telescope
2012-12-21 10:45:51

[ Watch the Video: All Systems Go for Highest Altitude Supercomputer ] Michael Harper for redOrbit.com — Your Universe Online When one begins to search for the origins of the universe, it helps to be well-equipped and as close to the heavens as possible. Therefore, the Atacama Large Millimeter/sub-millimeter Array (or ALMA) has been built high up in the martian-esque landscape of the Atacama desert of northern Chile. Each of these 66 radio telescopes (or giant antennas) are used...

Stellar Patrons Of The Milky Way Bar Identified By Astronomers
2012-12-19 15:03:31

SDSS-III Forget the restaurant at the end of the Universe – astronomers now have the clearest understanding yet of the bar at the center of the Milky Way. Scientists with the Sloan Digital Sky Survey III (SDSS-III) have announced the discovery of hundreds of stars rapidly moving together in long, looping orbits around the center of our Galaxy. "The best explanation for their orbits is that these stars are part of the Milky Way bar," says David Nidever, a Dean B. McLaughin Fellow...

Astronomers Offer High Resolution Image Of Cygnus Loop
2012-12-19 11:05:43

April Flowers for redOrbit.com - Your Universe Online The National Optical Astronomy Observatory (NOAO) and WIYN partners have offered this extraordinary wide-field image of the Cygnus loop as an end of the year finale. The image, three degrees to a side, covers an area of the sky about 45 times that of the full moon without sacrificing high resolution. The image is one of the largest astronomical images ever made at over 600 million pixels in size. Located some 1,500 light-years from...

Venus Transit And Lunar Mirror Could Help Find Other Planets
2012-12-14 05:12:06

Lee Rannals for redOrbit.com - Your Universe Online Astronomers reported in the journal Monthly Notices of the Royal Astronomical Society that looking at the sunlight reflected off the Moon during the Venus transit this year helped scientists find planets in orbit around other stars. As Venus passed in front of the Sun on June 6, 2012, it hid part of our sun's rotating surface. Because of rotation, the spectrum of the Sun is slightly different on each side. On one side of the sun,...

Vega Star Older Than Previously Thought
2012-12-12 10:00:24

April Flowers for redOrbit.com - Your Universe Online For thousands of years, astronomers have used Vega — the fifth brightest star in the night sky and the brightest in the constellation Lyra — as a touchstone to measure the brightness of other stars. Now, a new study from the University of Michigan demonstrates that Vega may be more than 200 million years older than scientists previously believed. Researchers were able to estimate Vega´s age by precisely measuring the...

ESO Installs New Instrument Onboard VLT
2012-12-12 07:57:44

Lee Rannals for redOrbit.com - Your Universe Online The European Southern Observatory (ESO) has tested out its latest instrument called KMOS on its Very Large Telescope (VLT) at the Paranal Observatory in Chile. The instrument, K-band Multi-Object Spectrograph (KMOS), is capable of observing 24 objects at the same time in infrared light, and study the structure simultaneously within each one. ESO said KMOS will help to provide crucial data to help understand how galaxies grew and...

NASA Gives Fermi Space Telescope Better Vision
2012-12-06 15:31:34

[Watch Video: Fermi Finds Radio Bursts From Terrestrial Gamma-Ray Flashes] Lee Rannals for redOrbit.com — Your Universe Online NASA's Fermi Gamma-ray Space Telescope is new and improved, and ready to start sending back some images of high-energy light mysteriously produced above thunderstorms. The space agency updated the telescope with improved data analysis techniques and a new operating mode to the Gamma-ray Burst Monitor (GBM) aboard Fermi. This will enable the...

Carina Nebula Image Ushers In A New ESO Telescope
2012-12-06 10:12:13

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online A new image released by the European Space Observatory (ESO) shows off a spectacular view of the star-forming Carina Nebula, and is being released right in time for an inauguration. Astronomers captured the Carina Nebula using the Very Large Telescope (VLT) Survey Telescope at ESO's Paranal Observatory. The image was released on the occasion of the inauguration of the telescope in Naples on Thursday. The...

Very Large Telescope -- The Very Large Telescope (VLT) consist of four optical telescopes that have 8.4 meter aperture. The VLT is a project of the European Southern Observatory organization. It is located at the Paranal Observatory on Cerro Paranal, a 2,635-m high mountain in the Atacama desert in northern Chile. The VLT consists of a cluster four of large telescopes, and an interferometer (VLTI) which will be used to resolve fine features. The telescopes have been named after the...

Overwhelmingly Large Telescope -- The European Southern Observatory has undertaken a concept study for the next generation of ground-based Extremely Large Telescopes (ELTs). Dubbed OWL, ESO's concept is conceived as a 100 m. diameter optical and near-infrared, adaptive telescope. With milliarc second resolution and limiting magnitude V~38, OWL will be capable of imaging solar system objects at resolutions comparable to that offered by space probes, over much longer time scales. It...

La Silla Observatory -- La Silla is a 2400-m mountain, bordering the southern extremity of the Atacama desert in Chile. It is located about 160 Km north of La Serena. Its geographical coordinates are: Latitude 29 15' south & Longitude 70 44' west. Originally known as Cinchado, the mountain was renamed La Silla (the saddle) after its shape. It rises quite isolated and remote from any artificial light and dust sources (astronomy's worst enemies). La Silla was the first ESO...

European Southern Observatory -- ESO, the European Southern Observatory, was created in 1962 to: "establish and operate an astronomical observatory in the southern hemisphere, equipped with powerful instruments, with the aim of furthering and organising collaboration in astronomy". ESO is supported by Belgium, Denmark, France, Germany, Italy, the Netherlands, Portugal, Sweden, Switzerland and United Kingdom. Other countries have expressed interest to become a member as well. ESO...

Mount Wilson Observatory -- astronomical observatory located in California on Mt. Wilson, near Pasadena. Mt. Wilson Observatory was founded in 1904 by George E. Hale. Its equipment includes 100-in. (2.5-m) and 60-in. (1.50-m) reflecting telescopes and two solar-tower telescopes 150 ft. (46 m) and 60 ft. (18 m) in length. The most recent addition is the CHARA (Center for High Angular Resolution Astronomy) array operated by Georgia State Univ.; it consists of six 39-in. (1-m) aperture...
