General Dynamics-built radio telescope antennas give scientists a microscopic view of the universe that is thousands of light years away. NEWTON, N.C., June 25, 2014 /PRNewswire/ -- General Dynamics SATCOM Technologies, a part of General Dynamics C4 Systems, will build and install a 100-ton, 12-meter (40-foot), submillimeter-wavelength radio telescope antenna for the new Large Latin American Millimeter Array (LLAMA) observatory. The LLAMA project is a joint venture between...

Black Hole Observed Pushing Matter Away, Rather Than Consuming It

Lawrence LeBlond for redOrbit.com - Your Universe Online Observations of a nearby active galaxy using the Very Large Telescope Interferometer (VLTI) at ESO´s Paranal Observatory in Chile have shown astronomers something they hadn´t expected to see. Astronomers have found over the past twenty years that nearly all galaxies have a black hole at their center, some of which grow by drawing in matter from their surroundings. This growth process creates some of the most energetic objects...

A team of astronomers at Jodrell Bank Observatory have begun the deepest ever high-resolution radio imaging of the region around the Hubble Deep Field (HDF), the images originally captured by the Hubble Space Telescope (HST) in the mid 1990s. The HDF led to the discovery of numerous galaxies billions of light years distant and provided direct visual evidence of the evolution of the Universe. First results from the new imaging, which uses observations from the UK's newly upgraded e-MERLIN...

Image 1 - Vampire Star Reveals Its Secrets

[ Video 1 ] | [ Video 2 ] Astronomers have obtained the best images ever of a star that has lost most of its material to a vampire companion. By combining the light captured by four telescopes at ESO´s Paranal Observatory they created a virtual telescope 130 meters across with vision 50 times sharper than the NASA/ESA Hubble Space Telescope. Surprisingly, the new results show that the transfer of mass from one star to the other in this double system is gentler than expected....

Spearheaded by the University of Manchester's Jodrell Bank Observatory and funded by the Science and Technology Facilities Council, the e-MERLIN telescope will allow astronomers to address key questions relating to the origin and evolution of galaxies, stars and planets. To demonstrate its capabilities, University of Manchester astronomers turned the new telescope array toward the "Double Quasar". This enigmatic object, first discovered by Jodrell Bank, is a famous example of Einstein's...

About 550 light-years from Earth, a star like our Sun is writhing in its death throes. Chi Cygni has swollen in size to become a red giant star so large that it would swallow every planet out to Mars in our solar system. Moreover, it has begun to pulse dramatically in and out, beating like a giant heart. New close-up photos of the surface of this distant star show its throbbing motions in unprecedented detail. "This work opens a window onto the fate of our Sun five billion years from now,...

Europe is sending its first home-built receiver to the largest radio telescope array ever constructed, nestled in its permanent home in Chile, BBC News reported. The Atacama Large Millimeter Array (Alma) is made up of sixty six 39-foot wide antenna dishes that detect the faint signals in the sub-millimeter wavelength range to learn more about the formation of stars and galaxies. Scientists at the Rutherford Appleton Laboratory (RAL) in Oxfordshire will assemble and test 26 of the receivers...

A team of French astronomers has captured one of the sharpest color images ever made. They observed the star T Leporis, which appears, on the sky, as small as a two-storey house on the Moon [1]. The image was taken with ESO's Very Large Telescope Interferometer (VLTI), emulating a virtual telescope about 100 meters across and reveals a spherical molecular shell around an aged star. "This is one of the first images made using near-infrared interferometry," says lead author Jean-Baptiste Le...

First Light for the PRIMA instrument The PRIMA instrument [1] of the ESO Very Large Telescope Interferometer (VLTI) recently saw "first light" at its new home atop Cerro Paranal in Chile. When fully operational, PRIMA will boost the capabilities of the VLTI to see sources much fainter than any previous interferometers, and enable astrometric precision unmatched by any other existing astronomical facility. PRIMA will be a unique tool for the detection of exoplanets. "PRIMA is specifically...

Interferometry -- Interferometry is the applied science of combining two or more input points of a data type, such as optical, and combine these data to form a greater picture based on the combination of the two sources. This technique is the basis for proposed radio telescope arrays, which spread out upon a wide area of hundreds of miles, can together produce a picture with resolution similar or equivalent to a single telescope with the diameter of the combined spread of telescopes. The...
