Jeffrey Mangum, a scientist at the National Radio Astronomy Observatory (NRAO) headquarters in Charlottesville, Virginia, has been appointed Editor of the Publications of the Astronomical Society of the Pacific (PASP), a peer-reviewed scientific journal. The tenth editor in PASP's 125-year history, Mangum will continue in his position on the NRAO's scientific staff, where he has worked fulltime since 1994. PASP is a publication of the Astronomical Society of the Pacific (ASP), a nonprofit...

Hot Gas Bridging Galaxy Cluster Pair Spotted By Plank
2012-11-20 10:46:32

ESA ESA´s Planck space telescope has made the first conclusive detection of a bridge of hot gas connecting a pair of galaxy clusters across 10 million light-years of intergalactic space. Planck´s primary task is to capture the most ancient light of the cosmos, the Cosmic Microwave Background, or CMB. As this faint light traverses the Universe, it encounters different types of structure including galaxies and galaxy clusters — assemblies of hundreds to thousands of...

Black Hole Blows Giant Plasma Bubble Like A Child Blowing Bubble Gum

Michael Harper for redOrbit.com — Your Universe Online The team at ASTRON, the Netherlands Institute for Radio Astronomy, has been pointing their low Frequency Array (or LOFAR) telescope at the sky since 2010, using bands of low frequencies to observe the heavens. With LOFAR, ASTRON is able to look deep into the heavens for signals of galaxies and other far away objects that haven´t yet reached earth. Now, after using a new, international version of LOFAR, called (ILT), the...

Pulsar Is Accompanied By Black Widow
2012-10-25 16:03:16

Lee Rannals for redOrbit.com — Your Universe Online Scientists at the Max Planck Institute have discovered a millisecond pulsar accompanied by an unusual sub-stellar partner known as a "black widow." The team has solved the mystery and identified the culprit of a source of strong gamma-rays found in the constellation of Centaurus back in 1994. Millisecond gamma-ray pulsar PSR J1311-3430 was found through a new data analysis method developed by the scientists at the Max Planck...

Distant Quasar Shows No Sign Of Feeding On Galaxy Of Stars
2012-10-24 12:05:36

Lee Rannals for redOrbit.com — Your Universe Online While looking at one of the most distant quasars in the universe, astronomers were surprised to not see an underlying host galaxy of stars feeding it. NASA said the best explanation is that the galaxy is shrouded in so much dust that the stars are completely hidden everywhere. As stars aged and burned out in the early universe, they filled interstellar space with dust as they lost their atmosphere. The quasar dates back to an...

Dead Stars Could Guide Future Spacecraft
2012-10-10 09:43:51

April Flowers for redOrbit.com - Your Universe Online The European Space Agency (ESA) has commissioned a research team, including scientists from the National Physical Laboratory (NPL) and the University of Leicester, to investigate the possibility of using dead stars to navigate in deep space. If it is found to be feasible, this technique could revolutionize the way spacecraft navigate in the outer Solar System and beyond. Currently, spacecraft navigation relies on radio transmissions...

Pulsar Speed And Rotation Explained By New Model
2012-10-09 14:38:04

Lee Rannals for redOrbit.com - Your Universe Online A new model developed by researchers at the University of Southampton explains how the spin of a pulsar slows down as the star gets older. A pulsar is a highly magnetized rotating neutron star that forms from the remains of a supernova which emits a rotating beam of electromagnetic radiation. Pulsars rotate at very stable speeds, but slow down as they emit radiation and lose their energy. Researchers now say that they have found a...

Quasar Clouds Gone With The Wind
2012-10-01 21:45:23

Lee Rannals for redOrbit.com — Your Universe Online The distant quasar gas clouds that seemed to disappear off the grid were gone with the wind, according to a study published in The Astrophysical Journal. Astronomers Nurten Filiz Ak and Niel Brandt of Pennsylvania State University led the team to search for the missing quasar gas clouds that seemed to disappear in just a few years. "We know that many quasars have structures of fast-moving gas caught up in 'quasar winds,' and...

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...

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...
