Latest Radio astronomy Stories
In the week that saw the release of the first results from the European Space Agency's Planck satellite, astronomers at the Hartebeesthoek Radio Astronomy Observatory (HartRAO) near Johannesburg are working on a new radio telescope that will also shed new light on the very earliest moments of universe.
Astronomers from the University of Colorado Boulder believe that so-called sideline quasars located on the outer fringes of a larger, brighter active galactic nucleus might have joined forces with it to prevent the formation of small galaxies billions of years ago.
For only the second time in history, a team of scientists including Michele Fumagalli from the Carnegie Institution for Science in the United States have discovered an extremely rare triple quasar system.
Angel Flight West attracts aviation enthusiasts to San Diego Air and Space Museum event where
The world was on edge earlier this month when North Korea detonated an underground nuclear explosion meant to showcase to the world community the abilities of this beleaguered nation.
On February 15, astronomers will have an exciting opportunity with a record-setting close approach of an asteroid. The research team, using the National Radio Astronomy Observatory (NRAO) and NASA telescopes, will gain a key clue that will help predict the future of this nearby cosmic neighbor.
Pulsars are one of the most baffling classes of astronomical objects. Originally discovered as flickering sources of radio waves, pulsars were soon interpreted as rapidly rotating and strongly magnetized neutron stars about the size of a small city.
Astronomers using CSIRO radio telescope have discovered that the Universe's temperature has cooled down, which falls right in line with the Big Bang theory.
Thanks to a powerful National Science Foundation telescope and an observation made by one National Radio Astronomy Observatory official, the W50 nebula located approximately 18,000 light years away has a new name – the Manatee Nebula.
ALMA (the Atacama Large Millimeter/submillimeter Array) has begun a new and more advanced phase of science observations. This phase is known as Early Science Cycle 1, and will last until October 2013.
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...
