Starburst Galaxy M82 - An Up Close And Personal Look
2013-12-10 04:23:24

redOrbit Staff & Wire Reports - Your Universe Online Astronomers have managed to get an up close and personal look at the nearby starburst galaxy M82, detecting concentrations of dense molecular gas surrounding regions of intense star formation and streams of material exiting the galaxy’s disk, the National Radio Astronomy Observatory (NRAO) announced Monday. The new data comes courtesy of the high-frequency Robert C. Byrd Green Bank Telescope (GBT), the world's largest,...

Using Talk Radio To Track Space Debris
2013-12-02 12:42:54

[ Watch the Video: Listening Up For Space Debris ] Lee Rannals for redOrbit.com - Your Universe Online Top-40 mixes being played over the FM airwaves are helping scientists locate space junk orbiting around our planet. Australian astronomers are using pop songs, talk radio and the Murchison Widefield Array (MWA) to help prevent catastrophic space junk collisions. As radio waves bounce around, they deflect off thousands of objects orbiting the Earth, which the team is able to take...

Throes Of Stellar Birth Revealed As Never Before
2013-11-12 04:04:45

April Flowers for redOrbit.com - Your Universe Online The bubbly birth of a bouncing baby star has been revealed by observations from NASA's Spitzer Space Telescope and the newly completed Atacama Large Millimeter/submillimeter Array (ALMA) in Chile. For the well-studied object known as HH 46/47, the observations have revealed the mechanisms of stellar birth as never before seen. HH, or Herbig-Haro, objects form when jets pushed out by newborn stars collide with material surrounding...

Former Missile Tracking Telescope Tracks Evolution Of Crab Pulsar
2013-10-31 16:31:02

Lee Rannals for redOrbit.com – Your Universe Online A former missile tracking telescope has helped astronomers determine how the magnetic field structure and rotation of a young and rapidly rotating Crab pulsar evolves. Scientists wrote in the journal Science about a 22-year experiment that involved observing a steady change in the flashes of the Crab pulsar. This highly-compact star emits beams of radio waves that produce flashes each time it rotates, which occurs about 30 times a...

ALMA Observatory Reveals Black Hole's Eating Habits
2013-10-16 10:12:37

[ Watch the Video: Zooming In On Active Galaxy NGC 1433 ] Brett Smith for redOrbit.com - Your Universe Online New observations from the Atacama Large Millimeter/submillimeter Array (ALMA) in the high-altitude Atacama Desert of Chile have revealed new details about the powerful molecular-gas jets that stream out of supermassive black holes, according to two new studies published on Wednesday in the journal Astronomy & Astrophysics. The two studies describe the unique behaviors and...

5 ways shutdown is bad for science
2013-10-07 11:44:33

[ Watch the Video: Science Isn't Safe From Government Shutdown ] Michael Harper for redOrbit.com - Your Universe Online Now entering its second week, the government shutdown has forced an awkward “define the relationship” conversation between those who write the paychecks and those who receive them. Without a clear decision on a new national budget, money to operate government services has become tight, meaning politicians have been left to define which government services are...

Final Antenna Now Handed Over To The ALMA observatory
2013-10-01 08:46:38

ESO The final antenna for the Atacama Large Millimeter/submillimeter Array (ALMA) project has just been handed over to the ALMA Observatory. The 12-meter-diameter dish was manufactured by the European AEM Consortium and also marks the successful delivery of a total of 25 European antennas — the largest ESO contract so far. The antenna is the 66th and final antenna to be delivered to the observatory. North America has provided 25 12-metre antennas, while East Asia has delivered 16...

Cat's Paw Nebula Viewed In High Detail With New Instrument
2013-09-25 10:18:55

Lee Rannals for redOrbit.com - Your Universe Online A new, powerful viewing instrument installed on the Atacama Pathfinder Experiment (APEX) has already given astronomers a detailed view of the Cat's Paw Nebula. The ArTeMiS is a new wide-field submillimeter-wavelength camera that will further increase the depth and detail that APEX can observe. The new instrument's detector acts more like a CCD camera than the previous generation of detectors, which will allow it to map the sky faster...

TheSkyNet Celebrating Second Anniversary
2013-09-13 09:22:04

ICRAR TheSkyNet is celebrating its two year anniversary today with the official launch of a new research project, as well as a range of improvements and new features to make contributing to astronomical research at home more enjoyable, and even easier. Launched on September 13th 2011, theSkyNet is a community computing project dedicated to astronomy, initiated by the International Centre of Radio Astronomy Research (ICRAR) in Perth, Western Australia. By using the idle processing...

Agreement For Research Collaboration With NRAO Green Bank Telescope Signed By AUI And West Virginia University
2013-08-26 14:18:54

National Radio Astronomy Observatory Associated Universities, Inc., (AUI) the organization that manages the National Radio Astronomy Observatory (NRAO), has signed an agreement with West Virginia University (WVU) to provide dedicated observing time on the Robert C. Byrd Green Bank Telescope (GBT). Under the agreement, West Virginia University will provide $1 million in financial support for the facility over the next two years. In return, WVU astronomers will get a proportional amount...

Very Large Array -- The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter. The VLA is an...

Radio Telescope -- In contrast to an ordinary telescope, which produces visible light images, a radio telescope "sees" radio waves emitted by radio sources located anywhere in the Universe, typically by means of a large parabolic ("dish") antenna, or arrays of them. The best-known (and largest) radio telescope is in Arecibo, Puerto Rico. A well-known radio telescope being an array of antennae is the Very Large Array (VLA) in Socorro, New Mexico. The largest (100-meter diameter) and most...

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...

National Radio Astronomy Observatory -- The National Radio Astronomy Observatory (NRAO) is a research facility of the U.S. National Science Foundation. They provide state-of-the-art radio telescope facilities for use by the scientific community. They conceive, design, build, operate and maintain radio telescopes used by scientists from around the world. Scientists use their facilities to study virtually all types of astronomical objects known, from planets and comets in our own Solar...

Jodrell Bank Observatory -- The Jodrell Bank Observatory, near Macclesfield, Cheshire in the north west of England is a part of the University of Manchester. It has played an important part in the research into quasars and pulsars, as well as the first detection of a gravitational lens in 1979, confirming one of Einstein's theories. It was established in 1945 by Dr. Bernard Lovell, who wanted to investigate cosmic rays after his work on radar in World War II. The first radio...
