Pulsar Planets And How To Find Them
2012-09-28 07:36:13

Lee Rannals for redOrbit.com - Your Universe Online Astronomer Fabrice Mottez made a series of predictions at the European Planetary Science Congress about the properties of planetary systems around pulsars. Pulsars are dense balls of matter which are heavier than the Sun, yet only are a few tens of miles in diameter. They rotate rapidly, and give off a bright flashing light, giving them their name "pulsating star." So far, there have been two pulsars observed that are home to...

Associated Universities Inc. (AUI) and the National Radio Astronomy Observatory (NRAO) have made a preliminary examination of the report released today from the National Science Foundation (NSF) Astronomy Portfolio Review Committee (PRC). Among the recommendations of that report are that the NSF´s Green Bank Telescope (GBT) and Very Long Baseline Array (VLBA) be fully divested from the NSF Astronomy Division´s portfolio of research facilities in the next five years, with no...

First Public Data Release From The Baryon Oscillation Spectroscopic Survey (BOSS)
2012-08-08 10:08:02

Led by Berkeley Lab scientists, the Sloan Digital Sky Survey´s BOSS is bigger than all other spectroscopic surveys combined for measuring the universe's large-scale structure The Third Sloan Digital Sky Survey (SDSS-III) has issued Data Release 9 (DR9), the first public release of data from the Baryon Oscillation Spectroscopic Survey (BOSS). In this release BOSS, the largest of SDSS-III's four surveys, provides spectra for 535,995 newly observed galaxies, 102,100 quasars, and 116,474...

Astronomers Locate Gamma-ray Pulsar With The Hiccups
2012-07-24 11:51:53

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online A special gamma-ray pulsar with the hiccups has been discovered by researchers from the Max Planck Institutes for Gravitational Physics and Radio Astronomy (MPIfR) using data constructed from the Fermi Gamma-ray Space Telescope. The pulsar J1838-0537 is very young, and has experienced the strongest rotation glitch ever observed for a gamma-ray-only pulsar. Pure gamma-ray pulsars are difficult to identify...

Jansky Very Large Array Achieves First Light
2012-07-22 07:59:27

redOrbit Staff & Wire Reports - Your Universe Online Researchers with the U.S. Naval Research Laboratory (NRL) and the National Radio Astronomy Observatory (NRAO) in New Mexico announced Friday that they had successfully achieved "first light" at low frequencies using the Jansky Very Large Array (JVLA) radio astronomy telescope. Using five of the JVLA's 27 230-ton, 25-meter diameter very high-frequency (VHF) dish antennas, NRAO astronomer Dr. Frazer Owen was able to map the radio...

Quasar Revealed In Unprecedented Detail

[ Watch Video 1 ] | [ Watch Video 2 ] | Watch Video 3 ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have made a crucial step towards a scientific goal by observing the heart of a distant quasar with angular resolution. An international team of astronomers connected radio telescopes in Chile, Hawaii and Arizona for the first time using the technique of Very Long Baseline Interferometry (VLBI), enabling them to make the sharpest observation ever of the center of a...

Astronomers Spot Fastest Moving Pulsar Ever
2012-06-29 13:31:30

[ Watch the Video ] Lee Rannals for redOrbit.com - Your Universe Online Researchers may have discovered the fastest moving pulsar ever seen using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. Astronomers used X-ray observations, combined with infrared data from the 2MASS project and optical data from the Digitized Sky Survey to find evidence for the record-breaking pulsar. The XMM-Newton image was produced when a massive star exploded as a supernova, leaving behind a...

Credit: NASA/ESA/Wikipedia What is Astrophysics? For much of the modern age the term Astrophysics has been used synonymously with Astronomy. This interchange is so common that many textbooks even offer the two as having the same meaning. However, from a strictly historical perspective there are differences...

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...

Sample Entry: Astronomy is the scientific study of stars, planets, comets, galaxies, and other phenomena that occur outside Earth's atmosphere (e.g. cosmic radiation). Astronomy deals with the evolution, physics, chemical makeup, meteorology, and motion of celestial objects, and also the formation of the universe. The word Astronomy comes from the Greek words astron (meaning "star") and nomos (meaning "law"). Astronomy is one of the oldest sciences. Since the dawn of man, people always...

Yakov Borisovich Zel'dovich (March 8, 1914 "“ December 2, 1987) was a productive Soviet physicist. He was instrumental in the advancement of Soviet nuclear and thermonuclear weapons, and also was an invaluable assistance in the fields of adsorption and catalysis, shock waves, nuclear physics, particle physics, astrophysics, physical cosmology, and general relativity. In 1914, he was born into a Jewish family in Minsk, now called Belarus. Four months after his birth, he and his family...

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...
