Latest Radio astronomy Stories
Astronomers investigating why the cosmic background radiation is much brighter at radio wavelengths than expected have identified a potential culprit: fast spinning black holes early in the galaxy formation process.
The Low Frequency Array (LOFAR), a new pan-European radio astronomy facility, has started mapping the Universe at very low energy wavelengths, a part of the electromagnetic spectrum that is relatively unexplored.
Supermassive black holes found at the centers of distant galaxies undergo huge growth spurts as a result of galactic collisions.
Up to now, primitive black holes, which occupy the cores of active galaxies and were around as far back as the early days of the universe, only existed in astronomerâ€™s models.
Astronomers have come across what appear to be two of the earliest and most primitive supermassive black holes known.
Quasars are active and very powerful black holes at the center of distant galaxies.
Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra.
GREENBELT, Md., March 10 /PRNewswire-USNewswire/ -- Distant galaxy clusters mysteriously stream at a million miles per hour along a path roughly centered on the southern constellations Centaurus and Hydra.
SARASOTA, Fla., March 4 /PRNewswire/ -- Quasar Bio-Tech Inc. is pleased to announce an exciting new partnership with Neiman Marcus, the nation's most refined retailer of luxury specialty products.
Astronomers have found the first clear evidence of a binary quasar within a pair of actively merging galaxies.

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...
