Black Hole Caught Belching In Neighboring Galaxy
2013-01-08 08:36:30

April Flowers for redOrbit.com - Your Universe Online A team of scientists conducting a long-term study of molecules in galaxies gained a tantalizing look at what is likely a powerful belch by a gorging black hole at the center of a changing galaxy. "The discovery was entirely serendipitous. Our observations were spread over a few years, and when we looked at them, we found that one galaxy had changed over that time from being placid and quiescent, to undergoing a hugely energetic...

ALMA Correlator Supercomputer Turns Man Antennas Into One Giant Telescope
2012-12-21 10:45:51

[ Watch the Video: All Systems Go for Highest Altitude Supercomputer ] Michael Harper for redOrbit.com — Your Universe Online When one begins to search for the origins of the universe, it helps to be well-equipped and as close to the heavens as possible. Therefore, the Atacama Large Millimeter/sub-millimeter Array (or ALMA) has been built high up in the martian-esque landscape of the Atacama desert of northern Chile. Each of these 66 radio telescopes (or giant antennas) are used...

Researchers Disprove Pulsar Glitch Theory
2012-12-18 16:21:44

Lee Rannals for redOrbit.com — Your Universe Online Researchers reported in the journal Physical Review Letters that they have found a "glitch" in a 40-year-old theory explaining the periodic speeding up or "glitching" of pulsars. Pulsars emit a rotating beam of electromagnetic radiation, which can be detected by powerful telescopes once it sweeps past the Earth. The cosmic objects, which are highly magnetized rotating neutron stars formed from the remains of supernovae, rotate...

Microquasar Found In Distant Galaxy
2012-12-12 13:35:22

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have found a microquasar in a galaxy far away for the first time, according to a report in the journal Nature. The discovery of the microquasar gives hope that more objects may be found in nearby galaxies, which could give astronomers the opportunity to study them in detail, unraveling some of their mysteries. In a microquasar, a black hole with a mass several times that of the Sun pulls material from its companion star...

Very Large Array Detected Two US Underground Nuclear Tests
2012-12-06 07:31:52

April Flowers for redOrbit.com - Your Universe Online Scientists searching for rogue nukes have discovered an unlikely tool, astronomical radio telescopes. When they demonstrated that South Korean GPS stations detected telltale atmospheric disturbances from North Korea's 2009 nuclear test, a research team from Ohio State University discovered another unlikely tool. The discovery that underground nuclear explosions leave their mark on the outer reaches of Earth's atmosphere led to the...

Big Boost To BigBOSS Givin By The Gordon And Betty Moore Foundation
2012-12-04 16:13:07

Lawrence Berkeley National Laboratory $2.1 Million Grant to Berkeley Center for Cosmological Physics advances dark energy research at UC Berkeley and Berkeley Lab A $2.1 million grant from the Gordon and Betty Moore Foundation to the University of California at Berkeley, through the Berkeley Center for Cosmological Physics (BCCP), will fund the development of revolutionary technologies for BigBOSS, a project now in the proposal stage designed to study dark energy with unprecedented...

To Attend The ALMA Observatory Inauguration Apply Now

European Southern Observatory (ESO) On 13 March 2013 the Atacama Large Millimeter/submillimeter Array (ALMA), the largest ground-based astronomical project in the world, will be inaugurated, celebrating ALMA´s transition from a construction project to a fully fledged observatory and marking the milestone of all the major systems of the observatory being operational. More than 50 of ALMA´s antennas will be in operation, and all 66 will be fully assembled. The inauguration ceremony...

Chandra Eyes Most Distant X-ray Jet Ever Observed
2012-11-29 10:00:20

April Flowers for redOrbit.com - Your Universe Online NASA's Chandra X-ray Observatory has detected a jet of X-rays from a supermassive black hole 12.4 billion light years from Earth, making it the most distant X-ray jet ever observed. The jet gives astronomers a glimpse into the explosive activity associated with super massive black hole growth in the early universe. A quasar named GB 1428+4217, or GB 1428 for short, produced the jet of X-rays. The black holes at the center of most...

Cosmic Outflow From Distant Quasar More Powerful Than Ever
2012-11-28 06:09:15

Lee Rannals for redOrbit.com - Your Universe Online Astronomers have reported in The Astrophysical Journal that they have found a quasar with the most energetic outflow ever seen. The quasar, SDSS J1106+1939, is at least five times more powerful than any that have been observed to date. Quasars are bright galactic centers powered by supermassive black holes. These cosmic objects outflows have never been observed as powerful as theorists have predicted, until now. The new study looked...

Image Caption: NGC 4414, a typical spiral galaxy in the constellation Coma Berenices, is about 56,000 light-years in diameter and approximately 60 million light-years distant. 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...
