Latest Radio astronomy Stories
At the center of the Milky Way lurks a supermassive black hole known as Sagittarius A*, with some four million times the mass of our Sun. More than any single object, it has the greatest impact on the formation, evolution and fate of our galaxy.
Recently, a team of three 3rd year students studying at the Niels Bohr Institute undertook a week long observation at the Nordic Optical Telescope in La Palma, Spain. Their mission: to take deeper, follow-up observations of a puzzling object that had been recently discovered.
South Africa's SKA Project (SKA SA) and the National Radio Astronomy Observatory (NRAO) in the US have agreed to continue their collaboration across a broad front to advance cutting-edge radio astronomy projects in both countries over the next five years.
Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars.
High-performance computing specialists from Perth’s International Centre for Radio Astronomy Research (ICRAR) today became the first users of one of Australia’s leading supercomputing facilities -- the Pawsey Centre -- ahead of its official opening later this year.
To promote academic research in the UK relating to the Search for Extraterrestrial Intelligence (SETI), a new network has been launched. Academics from 11 institutions across the UK are being brought together by the UK SETI Research Network (UKSRN), whose Patron is the Royal Astronomer, Professor Martin Rees.
Astronomers were able to catch a distant galaxy in the act of snacking on nearby gas while using the European Space Observatory's Very Large Telescope.
Astronomers said at a Royal Astronomical Society Meeting in St Andrews, Scotland on Monday that they have found a new way to map out quasars.
An international team of scientists led by astronomer Adam Deller (ASTRON) have used the Very Long Baseline Array (VLBA) to set a new distance accuracy record, pegging a pulsar called PSR J2222-0137 at 871.4 light-years from Earth.

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...
- The act of burning, scorching, or heating to dryness; the state or being thus heated or dried.
- In medicine, cauterization.
