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.

2013-07-01 12:24:07

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.

Astronomers Use The Very Long Baseline Array To Set New Record
2013-06-13 14:46:36

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.

Unusual Testbed For Analyzing X-ray Navigation Technologies Built By NASA
2013-05-21 08:20:54

Pulsars have a number of unusual qualities. Like zombies, they shine even though they’re technically dead, and they rotate rapidly, emitting powerful and regular beams of radiation that are seen as flashes of light, blinking on and off at intervals from seconds to milliseconds. A NASA team has built a first-of-a-kind testbed that simulates these distinctive pulsations.

PAPER Instrument In The Karoo Producing Ground-breaking Science And Spectacular Cosmic Images
2013-05-10 09:57:52

Scientific studies done with the "PAPER" array, one of the world-class scientific instruments in South Africa's Karoo Radio Astronomy Reserve, is producing ground-breaking science and spectacular cosmic images, resulting in several important articles in top astronomy journals.

Pinpointing Radio Wave Origins In The Distant Universe

For the first time, astronomers have identified discrete sources that account for nearly all of the radio waves coming from distant galaxies.

Cosmic Test Upholds Einstein's Theory Of General Relativity
2013-04-25 13:56:53

A team of researchers used telescopes around the world to study the most massive neutron star confirmed so far, orbited by a white dwarf. The scientists wrote in the journal Science that so far the new observations match up with Einstein's predictions for general relativity.

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...
