Milky Way Gas Cloud Creates Multiple Images Of Distant Quasar
2013-08-29 03:49:01

redOrbit Staff & Wire Reports - Your Universe Online Using the National Science Foundation's Very Long Baseline Array (VLBA) radio telescope system, astronomers have for the first time managed to capture an image of a distant quasar split into multiple images due to the effects of a cloud of ionized gas in the Milky Way. While these events were first predicted some four decades ago, the VLBA has managed to obtain the first evidence of their existence. Using the array, the...

Future Space Missions Could Rely On Pulsars For Navigation
2013-08-21 13:36:21

Lee Rannals for redOrbit.com - Your Universe Online Scientists at Commonwealth Scientific and Industrial Research Organization (CSIRO) are developing a new GPS method for spacecraft using pulsars. Pulsars are small spinning stars that emit regular pulses of radio waves and sometimes X-rays. CSIRO astronomers measure when these pulsar pulses arrive in our Solar System. This data can be used to give clues about the behavior of a pulsar itself or whether it is orbiting another star. Dr...

Highly Magnetized Pulsar At Galactic Center
2013-08-14 12:20:25

John P. Millis, PhD for redOrbit.com - Your Universe Online 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. However, probing this massive object is difficult. Due to the nature of black holes, most of what we learn about their existence is derived by observing their influence on other nearby...

Quasar Observed In 6 Separate Light Reflections

John P. Millis, Ph.D. for redOrbit.com - Your Universe Online Part of the educational process for college students majoring in the sciences is to engage in research activities, helping them to experience the challenges and triumphs they will experience in their careers. Because of the learning curve for most research progress, as well as small windows of time in order to complete the projects, undergraduate research experiences are often less-than-exciting. Occasionally, however, a...

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. An agreement signed in Cape Town on 5 August 2013 paves the way for the organizations to pool resources and expertise in high-level projects related to the development and implementation of software, data processing and archiving and...

Quasar Radiation Influences Galaxy Growth
2013-07-25 05:58:07

Lee Rannals for redOrbit.com - Your Universe Online Astrophysicists writing in The Astrophysical Journal have shed some new light on the universe's brightest objects - quasars. The team from Dartmouth University published details about discoveries based on 10 quasar observations. They wrote about the power of quasar radiation, which can reach out for many thousands of light years to the limits of the quasar's galaxy. Astrophysicists Ryan Hickox and Kevin Hainline and colleagues used...

Age Of Astronomy Big Data Is Already Here

ICRAR 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. The recent launch of the Murchison Widefield Array (MWA) -- a radio telescope based in Western Australia's Mid West -- marked the start of an impressive flow of astronomical data that will be stored in the iVEC-managed...

UK Launches SETI Network
2013-07-06 04:47:37

April Flowers for redOrbit.com - Your Universe Online 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. The network covers a wide range of diverse topics, including potential methods for detecting signals, the linguistic challenge...

Astronomers Catch Distant Galaxy Snacking On Gas
2013-07-04 13:01:16

Lee Rannals for redOrbit.com - Your Universe Online Astronomers were recently able to catch a distant galaxy in the act of snacking on nearby gas while using the European Southern Observatory's (ESO) Very Large Telescope (VLT). The team wrote in the journal Science about how they were able to make the best direct observational evidence so far supporting the theory that galaxies pull in and devour nearby material to grow and form stars. Scientists have always suspected galaxies grow this...

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...
