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

SKA 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. The primary goal of PAPER (Precision Array to Probe the Epoch of Reionization) is to detect emission from the neutral gas that pervaded the universe before the first galaxies and black holes were formed. This...

Clouds Of Hydrogen Gas Found In Our Galactic Backyard
2013-05-08 12:37:51

Watch the video “Intergalactic Clouds Lurk Between Nearby Galaxies" John P. Millis, PhD for redOrbit.com — Your Universe Online As we gaze into space beyond the confines of our own Milky Way, we see a Universe filled with galaxies. But what scientists have come to realize is that the emptiness that spans between these giant pools of stars is not empty at all, but rather is filled with massive amounts of gas. In fact, these gas reservoirs can sometimes outweigh the galaxies...

SKA Organization Headquarters Opening Ceremony Paves The Way For World’s Largest Radio Telescope
2013-05-07 13:52:09

Square Kilometre Array Less than a year after the decision to site the revolutionary Square Kilometre Array (SKA) in both Southern Africa and Australia, the SKA Organisation has opened its new international headquarters. In front of an invited audience of local and global dignitaries, scientists and engineers, the UK Minister for Universities and Science the Rt. Hon. David Willetts MP recently opened the building which will be home to the team managing the construction, design and...

Young Universe Was A Massive Factory For Star Formation
2013-04-17 13:36:09

Lee Rannals for redOrbit.com — Your Universe Online Astronomers say they have discovered a star factory in a galaxy so distant that they see it when the Universe was only six percent of its current age of about 13.7 billion years old. The team wrote in the journal Nature that HFLS3 sits at about 12.8 billion light-years from Earth. They said the distant galaxy is producing about 3,000 Suns per year, which is more than 2,000 times that of our own Milky Way galaxy. "This is the...

Early Star Forming Galaxies
2013-04-17 05:09:48

Lee Rannals for redOrbit.com - Your Universe Online Astronomers report in The Astrophysical Journal that they have determined the positions of over 100 of the most fertile star-forming galaxies in the early Universe. The group used the new Atacama Large Millimeter/submillimeter Array (ALMA) telescope during their observations. This telescope can capture just as many observations of this group of galaxies in just a few hours as similar telescopes can in more than a decade. [ Video:...

High-speed Cameras For Westerbork Telescope
2013-04-15 10:11:15

ASTRON This week, a team of Dutch astronomers and engineers led by astronomer Joeri van Leeuwen (ASTRON) was awarded a grant to turn the new ℠Apertif' receivers on the Westerbork telescope into high-speed cameras. The receivers will expand the Westerbork field of view by over a factor 30 but the system is restricted to making images at the rate of one every second. The new upgrade increases this to 10,000 frames per second, allowing astronomers to survey the sky with greater...

Scientists Discover The Earliest Known Starburst Galaxies In The Universe
2013-04-05 15:32:28

Brett Smith for redOrbit.com - Your Universe Online An international team of researchers announced it has found some of the Universe´s earliest starburst galaxies, essentially young energetic clusters of cosmic gas and dust that form stars at an alarming rate. The discoveries, which were detailed in reports published in Nature and the Astrophysical Journal, were made using the newly inaugurated Atacama Large Millimeter/submillimeter Array (ALMA) telescope. In its first billions...

New Light Shed On The Earliest Moments Of The Universe Using New Radio Telescope
2013-03-27 10:47:16

Square Kilometre Array (SKA) Africa 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. The C-Band All-Sky Survey (C-BASS) is a project to map the sky in microwave (short-wavelength radio) radiation. Like Planck, it will survey the whole...

Europe's Herschel Space Observatory Has Detected Some Very Young Stars
2013-03-20 10:59:56

April Flowers for redOrbit.com - Your Universe Online Some of the youngest stars ever seen have recently been found, thanks to the European Space Agency's (ESA) Herschel Space Observatory. Herschel's observations were used in conjunction with contributing observations from NASA's Spitzer Space Telescope and the Atacama Pathfinder Experiment (APEX) telescope in Chile -- a collaboration involving the Max Planck Institute for Radio Astronomy (MPIFR) in Germany, the Onsala Space Observatory...

Previously Unknown Giant Radio Galaxy Discovered By LOFAR
2013-03-19 14:56:58

Lee Rannals for redOrbit.com — Your Universe Online Astronomers have discovered a previously unknown gigantic radio galaxy using the powerful International LOFAR Telescope (ILT). The team was browsing the first set of photos taken during LOFAR's first all-sky imaging survey known as the Multi-frequency Snapshot Sky Survey (MSSS). While browsing the first set of MSSS images, ASTRON astronomer Dr. George Heald found a new source of radio emission the size of the full moon...

Very Large Array -- The Very Large Array, one of the world's premier astronomical radio observatories, consists of 27 radio antennas in a Y-shaped configuration on the Plains of San Agustin fifty miles west of Socorro, New Mexico. Each antenna is 25 meters (82 feet) in diameter. The data from the antennas is combined electronically to give the resolution of an antenna 36km (22 miles) across, with the sensitivity of a dish 130 meters (422 feet) in diameter. The VLA is an...

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...

Radio Astronomy -- Radio astronomy is the study of celestial phenomena through measurement of the characteristics of radio waves emitted by physical processes occurring in space. Radio waves are much longer than light waves. In order to receive good signals, radio astronomy requires large antennas. Radio astronomy is a relatively new field of astronomical research. The earliest investigations into extraterrestrial sources of radio waves were by Karl Guthe Jansky, an engineer with Bell...

Jodrell Bank Observatory -- The Jodrell Bank Observatory, near Macclesfield, Cheshire in the north west of England is a part of the University of Manchester. It has played an important part in the research into quasars and pulsars, as well as the first detection of a gravitational lens in 1979, confirming one of Einstein's theories. It was established in 1945 by Dr. Bernard Lovell, who wanted to investigate cosmic rays after his work on radar in World War II. The first radio...
