Pulsars in many octaves A unique combination of telescopes allowed astronomers to simultaneously observe the radio wavelength light from six different pulsars across wavelengths from only 3.5 centimetres up to 7 metres - a difference-factor of 200, providing an unprecedented view of how radio pulsars shine. For this world record in wavelength coverage, the international team, including scientists from the Max Planck Institute for Radio Astronomy, used the new European LOFAR telescope, in...

The Low Frequency Array (LOFAR), a new pan-European radio astronomy facility, has started mapping the Universe at very low energy wavelengths, a part of the electromagnetic spectrum that is relatively unexplored. It will detect faint signals from the first stars and mini-black holes that emerged when the Universe was only 500 000 years old "“ and will also be looking for signs of other civilizations in the Universe closer to home. Dr John McKean will present the first images at the RAS...

On March 30 and 31 a strategic international workshop on the Square Kilometer Array (SKA) will seek to identify the major economical and societal benefits of large-scale scientific research infrastructure investments. The SKA is a USD 1 billion+ international project to create a radio telescope incorporating a receiving surface of a million square meters, fifty times larger than the biggest receiving surface now in existence. This huge surface will be composed of many small antennas, divided...

An International group of four professional stargazers are backing Chile's Atacama Desert as the future home to the world's biggest telescope. The telescope is on schedule to be built in 2018, and astronomers say Chile provides the perfect conditions due to its geographical advantages. The experts say that because of its cloud-free skies 360 nights a year, the high-altitude Armazones mountains in northern Chilean desert is the perfect place for the European Extremely Large Telescope (ELT)....

An international team of scientists, including several astronomers from the Joint Institute for VLBI in Europe (JIVE) and the Netherlands Institute for Radio Astronomy (ASTRON), both located in Dwingeloo, have observed a supernova with peculiar radio emission. In a paper to be published in the January 28, 2010 issue of Nature, the team led by JIVE's Zsolt Paragi reports, for the first time ever, detection of a relativistic outflow in a Type Ic supernova, thus supporting the link with the even...

The Atacama Large Millimeter/submillimeter Array (ALMA) has passed a key milestone crucial for the high quality images that will be the trademark of this revolutionary new tool for astronomy. Astronomers and engineers have, for the first time, successfully linked three of the observatory's antennas at the 5000-meter elevation observing site in northern Chile. Having three antennas observing in unison paves the way for precise images of the cool Universe at unprecedented resolution, by...

An instrument package developed in part by the University of Colorado at Boulder for the $2.2 billion orbiting Herschel Space Observatory launched in May by the European Space Agency has provided one of the most detailed views yet of space up to 12 billion years back in time. The December images have revealed thousands of newly discovered galaxies in their early stages of formation, said CU-Boulder Associate Professor Jason Glenn, a co-investigator on the Spectral and Photometric Imaging...

It's going to take infrared eyes to see farther back in time than even the Hubble Space Telescope, and that's what the James Webb Space Telescope's MIRI or Mid-Infrared Instrument detectors will do. Now there's a new short movie that shows what the MIRI detectors are all about and what they can do. "The MIRI is one of four science instruments aboard the Webb telescope that is designed to record images and spectra at the longest wavelengths that the Webb telescope can observe," said Matt...

Astronomers facing Socratic "ignorance" An extensive study made with ESO's Very Large Telescope deepens a long-standing mystery in the study of stars similar to the Sun. Unusual year-long variations in the brightness of about one third of all Sun-like stars during the latter stages of their lives still remain unexplained. Over the past few decades, astronomers have offered many possible explanations, but the new, painstaking observations contradict them all and only deepen the mystery. The...

NEWTON, N.C., Nov. 20 /PRNewswire/ -- The first of 25 North American antennas to be manufactured by General Dynamics SATCOM Technologies for the Atacama Large Millimeter/Submillimeter Array (ALMA) astronomical observatory was recently installed at the ALMA Operations Site located high in the Chilean Andes. Traveling on a custom-built transporter from the ALMA Operations Support Facility at 9,500 feet above sea level, the 12-meter, 100-ton antenna made a 22-mile trek to the Array...

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...
