Latest Radio astronomy Stories
Whether on their own or orbiting as a pair, black holes donâ€™t typically sit still.
The discovery potential of the future international SKA radio telescope has been glimpsed following the commissioning of a working optical fibre link between CSIROâ€™s Australian SKA Pathfinder (ASKAP) telescope in Western Australia, and other radio telescopes across Australia and New Zealand.
Astronomers are puzzled by the announcement that the masses of the largest objects in the Universe appear to depend on which method is used to weigh them.
WASHINGTON, June 15, 2011 /PRNewswire-USNewswire/ -- Using the deepest X-ray image ever taken, astronomers found the first direct evidence that massive black holes were common in the early universe.
Early results from dramatically upgraded telescope show breadth of scientific impact.
The biggest 3-D map of the distant universe ever made, using light from 14,000 quasars â€“ supermassive black holes at the centers of galaxies billions of light years away â€“ has been constructed by scientists with the third Sloan Digital Sky Survey (SDSS-III).
Astronomers from Wales and the Netherlands, in collaboration with five schools, have used eight telescopes simultaneously to study the strange behavior of an X-ray binary star system.
A powerful new telescope is allowing an international team led by University of Manchester scientists to have their â€œbest-ever lookâ€ at pulsars â€“ rapidly rotating neutron stars created when massive stars die.
Continent-wide telescope extends cosmic 'yardstick' three times farther into universe.
Astronomers gazing deep into the night sky to uncover the Universe's secrets will soon be able to discover even more star-births and planets thanks to new telescopes being built in Chile and Mexico drawing on space technology.

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...
