New Pulsars Discovered In Archival Data
2013-08-29 08:25:39

AlphaGalileo Foundation Einstein@Home discovers 24 new pulsars in archival data. The combined computing power of 200,000 private PCs helps astronomers take an inventory of the Milky Way. The Einstein@Home project connects home and office PCs of volunteers from around the world to a global supercomputer. Using this computer cloud, an international team lead by scientists from the Max Planck Institutes for Gravitational Physics and for Radio Astronomy analyzed archival data from the CSIRO...

Pinpointing Radio Wave Origins In The Distant Universe
2013-05-01 05:04:41

April Flowers for redOrbit.com - Your Universe Online For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies. This was achieved by more than 50 hours of observations with the ultra-sensitive Karl G. Jansky Very Large Array (VLA). The researchers found that approximately 63 percent of the background radio emission comes from galaxies with gorging black holes at their cores. The remaining 37 percent...

US astronomers said Friday that they are now listening to the skies for the existence of ETs, using a massive radio telescope in West Virginia to scan for signs of alien life on 86 possible Earth-like planets in the heavens above.The giant dish began pointing toward each of the planets this week and will gather 24 hours of data on each one. The 86 planets were gleaned from a list of 1,235 planets identified by NASA's Kepler space telescope."It's not absolutely certain that all of these stars...

Why sunspots are a strong source of radio emissions and what information those emissions carry will be the focus of an invited talk by NJIT Research Professor Jeongwoo Lee tomorrow at the International Astronomical Union Symposium on the Physics of Sun and Star Spots in Ventura, CA. The event numbers among the top gatherings in the U.S. for people studying sunspots and related phenomena. Lee, who will speak today, Aug. 26, 2010, will highlight Owens Valley Solar Array (OVSA), one of the two...

MOUNTAIN VIEW, Calif., April 19 /PRNewswire/ -- SETI Institute, an interdisciplinary scientific organization that explores the nature of life throughout the universe, announced that starting today it will make large quantities of astronomical radio telescope data accessible to astronomers and other scientists as part of an effort to build a global community of searchers for evidence of extra-terrestrial intelligence. Today's announcement represents the latest milestone in SETI Institute's...

WASHINGTON, Dec. 5 /PRNewswire-USNewswire/ -- Radio astronomers have uncovered 17 millisecond pulsars in our galaxy by studying unknown high-energy sources detected by NASA's Fermi Gamma-ray Space Telescope. The astronomers made the discovery in less than three months. Such a jump in the pace of locating these hard-to-find objects holds the promise of using them as a kind of "galactic GPS" to detect gravitational waves passing near Earth. (Logo:...

Following the launch of ESA's SMOS satellite on 2 November, the French space agency CNES, which is responsible for operating the satellite, has confirmed that the instrument's three antenna arms have deployed as planned, and that the instrument is in good health. During launch and the first few orbits around Earth, the Soil Moisture and Ocean Salinity (SMOS) instrument's antenna arms remained safely folded up. Today, these three arms folded-out and now form a large three-pointed star shape....

Many of us have been rescued from unfamiliar territory by directions from a Global Positioning System (GPS) navigator. GPS satellites send signals to a receiver in your GPS navigator, which calculates your position based on the location of the satellites and your distance from them. The distance is determined by how long it took the signals from various satellites to reach your receiver. The system works well, and millions rely on it every day, but what tells the GPS satellites where they are...

An international team of astronomers has used a U.S. radio telescope to study the brightest galaxies that the Fermi Gamma-ray Space Telescope can see. Yuri Kovalev at the Max Planck Institute for Radio Astronomy in Germany said the study solidifies the link between an active galaxy's gamma-ray emissions and its powerful radio-emitting jets. Kovalev and colleagues used the world's largest radio telescope -- the National Science Foundation's Very Long Baseline Array -- a set of 10 radio...

Five astronomy students at the University of Wisconsin-Madison have carried their research to unexpected heights -- they found a galaxy. They made their improbable find in a most improbable way, using the world's largest radio telescope, the Arecibo Observatory in Puerto Rico. The students told the Wisconsin Sate Journal that their good fortune was not expected when they signed up for a research methods class being taught by UW-Madison astronomer Snezana Stanimirovic. But the astronomer had...

Radio telescopes, used in tracking and collecting data from satellites and space probes, are a form of directional radio antenna used in radio astronomy. They operate on the radio frequency portion of the electromagnetic spectrum where they detect radio sources. Radio telescopes are large parabolic antennas used singly or in an array and are located far from major centers of population in order to avoid electromagnetic interference. Karl Guthe Jansky built the first radio antenna used to...

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...

Interferometry -- Interferometry is the applied science of combining two or more input points of a data type, such as optical, and combine these data to form a greater picture based on the combination of the two sources. This technique is the basis for proposed radio telescope arrays, which spread out upon a wide area of hundreds of miles, can together produce a picture with resolution similar or equivalent to a single telescope with the diameter of the combined spread of telescopes. The...
