Brown Dwarf Stars Can Grow Rocky Planets
2012-11-30 06:05:22

Lee Rannals for redOrbit.com - Your Universe Online - Video 1 | Video 2 | Video 3 Astronomers using the Atacama Large Millimeter/submillimeter Array (ALMA) have discovered that the outer region of a dusty disc encircling a brown dwarf contains solid grains like those found in denser discs of newborn stars. The find challenges theories of how rock, Earth-scale planets form, suggesting the planets may be more common in the Universe than expected. Scientists believe rocky planets form...

Final US Antenna Dishes For ALMA Delivered
2012-11-21 05:07:52

April Flowers for redOrbit.com - Your Universe Online It has taken more than a decade of design and construction, but North America has finally delivered the last of 25 antenna dishes, marking an important milestone in the construction of an observatory astronomers are using to open up a "final frontier" of the spectrum of visible light to exploration. The dishes are 12-meters in diameter, and comprise the North American share of antennas for the international ALMA telescope. Stretching...

Michael Harper for redOrbit.com — Your Universe Online The team at ASTRON, the Netherlands Institute for Radio Astronomy, has been pointing their low Frequency Array (or LOFAR) telescope at the sky since 2010, using bands of low frequencies to observe the heavens. With LOFAR, ASTRON is able to look deep into the heavens for signals of galaxies and other far away objects that haven´t yet reached earth. Now, after using a new, international version of LOFAR, called (ILT), the...

Old Star May Have A Companion

[ Watch the Video: Slicing Through View of the Material Around R Sculptoris ] Lee Rannals for redOrbit.com - Your Universe Online Astronomers have discovered an unexpected spiral structure in the material around an old star called R Sculptoris The team used the Atacama Large Millimeter/submillimeter Array (ALMA) to discover the surprising spiral structure in the gas around the red giant star, which could mean there is a previously unseen companion star orbiting the star....

SKA Project Visited By President Zuma To Celebrate An African Science Success Story
2012-10-09 17:39:40

South Africa's President joined dignitaries, scientists, a large media contingent and members of the local community in the small town of Carnarvon today to celebrate South Africa's successful bid to build the world's largest scientific instrument — the Square Kilometre Array — in Africa. President Jacob Zuma touched down by helicopter at the telescope site about 100 km from Carnarvon where the first seven telescope dishes are already operational. The newly appointed Minister...

Australia Unveils ASKAP Telescope
2012-10-05 21:32:55

Lee Rannals for redOrbit.com — Your Universe Online Australia has unveiled a new $155 million telescope that could start to capture radio images as soon as today. The Australian Square Kilometer Array Pathfinder (ASKAP) is one of the world's fastest telescopes and sits in Australia's outback. ASKAP has 36 antennas with a diameter of 40 feet each and forms part of the world's biggest radio telescope projects. The telescope is located at the Murchison Radio-Astronomy...

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...
