Kinetic Sunyaev-Zel'dovich Effect Observed In Individual Object For The First Time
2014-01-17 11:14:32

redOrbit Staff & Wire Reports - Your Universe Online Scientists from the California Institute of Technology (Caltech) and NASA’s Jet Propulsion Laboratory (JPL) report in a recent study that they have observed a change in an individual object’s cosmic microwave background radiation resulting from its interaction with massive moving objects for the first time ever. According to the recently-published paper in The Astrophysical Journal, this phenomenon, which is known as the...

Quasars Illuminate Swirling Clouds Around Galaxies
2014-01-09 08:49:42

University of Illinois at Urbana-Champaign A new study of light from quasars has provided astronomers with illuminating insights into the swirling clouds of gas that form stars and galaxies, proving that the clouds can shift and change much more quickly than previously thought. Led by University of Illinois at Urbana-Champaign astronomy professor Robert J. Brunner and former graduate student Troy Hacker (now with the U.S. Air Force), the astronomers published their findings in the...

Gravity Clues From Stellar Triple System
2014-01-06 03:39:45

redOrbit Staff & Wire Reports - Your Universe Online The discovery of a superdense neutron star in a stellar triple system has made it possible for researchers to collect the best measurements to date of the complex gravitational interactions present in these types of systems, according to a new study in Nature. Using the National Science Foundation's Green Bank Telescope (GBT), the study authors were able to locate the pulsar along with two white dwarf stars in a compact area...

Astronomers See The Light With Help From Citizen Scientists

National Science Foundation Einstein@Home volunteers find four Gamma-ray pulsars and shed light on another part of the galaxy The combination of globally distributed computing power and innovative analysis methods is now a proven formula for the discovery of new once-elusive pulsars. Scientists from the Max Planck Institutes for Gravitational Physics and Radio Astronomy together with volunteers from Australia, Canada, France, Germany, Japan and the United States discovered four...

Revealing New Information On Strength Of Black Hole Mergers
2013-11-08 07:13:10

Lee Rannals for redOrbit.com - Your Universe Online The Commonwealth Scientific and Industrial Research Organization (CSIRO) in eastern Australia has helped reveal new information about the strength of black hole mergers. Giant black holes throughout the universe sometimes pair up and merge, sending out gravitational waves that ripple across space and time. Albert Einstein predicted that these waves exist, but scientists have yet to directly detect one. Astronomers were able to...

Former Missile Tracking Telescope Tracks Evolution Of Crab Pulsar
2013-10-31 16:31:02

Lee Rannals for redOrbit.com – Your Universe Online A former missile tracking telescope has helped astronomers determine how the magnetic field structure and rotation of a young and rapidly rotating Crab pulsar evolves. Scientists wrote in the journal Science about a 22-year experiment that involved observing a steady change in the flashes of the Crab pulsar. This highly-compact star emits beams of radio waves that produce flashes each time it rotates, which occurs about 30 times a...

5 ways shutdown is bad for science
2013-10-07 11:44:33

[ Watch the Video: Science Isn't Safe From Government Shutdown ] Michael Harper for redOrbit.com - Your Universe Online Now entering its second week, the government shutdown has forced an awkward “define the relationship” conversation between those who write the paychecks and those who receive them. Without a clear decision on a new national budget, money to operate government services has become tight, meaning politicians have been left to define which government services are...

Jekyll And Hyde Pulsar Has A Split Personality
2013-09-26 04:31:06

Lee Rannals for redOrbit.com - Your Universe Online [ Watch the Video: Millisecond Pulsar with Magnetic Field Structure ] Scientists writing in the journal Nature say they have discovered a millisecond pulsar with a dual identity. The team used NASA's Swift and Chandra X-ray Observatory to find a pulsar that readily shifts back and forth between two mutually exclusive styles of pulsed emission, including one in X-rays and another in radio. Scientists say this discovery represents an...

TheSkyNet Celebrating Second Anniversary
2013-09-13 09:22:04

ICRAR TheSkyNet is celebrating its two year anniversary today with the official launch of a new research project, as well as a range of improvements and new features to make contributing to astronomical research at home more enjoyable, and even easier. Launched on September 13th 2011, theSkyNet is a community computing project dedicated to astronomy, initiated by the International Centre of Radio Astronomy Research (ICRAR) in Perth, Western Australia. By using the idle processing...

Black Hole Blows Powerful Streams
2013-09-06 08:51:29

April Flowers for redOrbit.com - Your Universe Online A worldwide network of radio telescopes has allowed astronomers to find strong evidence that a powerful jet of material, propelled to nearly light speed by the central black hole of a galaxy, is blowing massive amounts of gas out of the host galaxy. The scientists say the process is limiting the growth of the black hole and the rate of star formation in the galaxy. That makes the process a key to understanding how galaxies develop....

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...
