Green Light For ALMA Early Science Cycle 1
2013-01-10 11:56:58

European Southern Observatory (ESO) ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013. The telescope´s power has been greatly increased: it will make observations with more antennas, spread over a greater distance, than ever before, and will use antennas from the Atacama Compact Array (ACA) for the first time. Although ALMA is still...

Starbursts Caught Near The Milky Way's Galactic Center
2013-01-09 10:47:01

redOrbit Staff & Wire Reports - Your Universe Online Using the airborne telescope on the Stratospheric Observatory for Infrared Astronomy (SOFIA), astronomers have learned that a series of recent starbursts had taken place in the central region of the Milky Way, NASA officials reported on Tuesday. According to the US space agency, our galaxy´s nucleus is home to a black hole with four million times the mass of the sun. It is orbited by a large disk of dust and gas, and holds...

New Methods Realized For Imaging The Center Of The Milky Way
2013-01-08 14:22:37

Rayshell Clapper for redOrbit.com - Your Universe Online Astronomers may now have a way to image the center of the Milky Way galaxy, which has posed problems to scientists trying to image all of its exotic features. Soon they may be able to learn more about the features of the center of the Milky Way and learn more about where they are located in the galaxy by use of radio waves. Prior to the discovery of radio waves, astronomers primarily used optical waves like the X-ray and infrared...

Black Hole Caught Belching In Neighboring Galaxy
2013-01-08 08:36:30

April Flowers for redOrbit.com - Your Universe Online A team of scientists conducting a long-term study of molecules in galaxies gained a tantalizing look at what is likely a powerful belch by a gorging black hole at the center of a changing galaxy. "The discovery was entirely serendipitous. Our observations were spread over a few years, and when we looked at them, we found that one galaxy had changed over that time from being placid and quiescent, to undergoing a hugely energetic...

Planet Forming Gas Streams Revealed
2013-01-02 12:09:51

[ Video 1 ] | [ Video 2 ] Lee Rannals for redOrbit.com - Your Universe Online Listen to the podcast “How Planets Form” with redOrbit's Dr. John Millis and planet-hunting expert Dr. Eric Mamajek of the University of Rochester. Astronomers who made observations with the Atacama Large Millimeter/submillimeter Array (ALMA) telescope are helping to shed light on planet-forming gas streams. The international team of astronomers studied the young star HD 142527, seeing a key...

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...

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...
