Molecules of hydrogen peroxide have been found for the first time in interstellar space. The discovery gives clues about the chemical link between two molecules critical for life: water and oxygen. On Earth, hydrogen peroxide plays a key role in the chemistry of water and ozone in our planet's atmosphere, and is familiar for its use as a disinfectant or to bleach hair blonde. Now it has been detected in space by astronomers using the ESO-operated APEX telescope in Chile. An international team...

Early results from dramatically upgraded telescope show breadth of scientific impact A new and uniquely powerful tool for cutting-edge science is emerging on the crisp, high desert of western New Mexico. Outwardly, it looks much the same as the famed Very Large Array (VLA), a radio telescope that has spent more than three decades on the frontiers of astronomical research. The 27 white, 230-ton dish antennas still peer skyward, the 72 miles of railroad track still wait to transport the...

Since the dawn of the space age, humanity has sent 16 robotic emissaries to fly by some of the solar system's most intriguing and nomadic occupants -- comets and asteroids. The data and imagery collected on these deep-space missions of exploration have helped redefine our understanding of how Earth and our part of the galaxy came to be. But this fall, Mother Nature is giving scientists around the world a close-up view of one of her good-sized space rocks -- no rocket required. "On November 8,...

A powerful new telescope is allowing an international team led by University of Manchester scientists to have their "best-ever look" at pulsars "“ rapidly rotating neutron stars created when massive stars die. In the first scientific results from the new European telescope LOFAR (Low Frequency Array) to appear in a journal "“ Astronomy & Astrophysics "“ the scientists present the most sensitive, low-frequency observations of pulsars ever made. The International LOFAR...

Jodrell Bank Observatory in Cheshire has been selected to take part in a $2.1 billion project to build the world's biggest radio telescope. Jodrell Bank signed an agreement with Australia, China, the Netherlands, New Zealand, South Africa, France, Germany Italy, and the U.K. to run the Square Kilometer Array (SKA). SKA is designed to answer some key questions about the Universe. They have not decided on the location of the project but it could be built in Australia or Southern Africa. The...

Scientists use innovative Radio Aurora Explorer satellite to discover conditions that cause disruptions in space-based communication and navigation signals Space weather-based disturbances in the Earth's upper atmosphere cause disruptions that affect space-based communication and navigation signals, such as GPS and radio signals. Radio Aurora Explorer (RAX) is a space weather research satellite that is designed to investigate the causes of these weather disturbances. RAX is the first...

Using a perfectly orchestrated world-wide network of radio telescopes, astronomers have produced a high-resolution map of an Active Galactic Nucleus (AGN) belonging to an unknown class of gamma-ray sources. The unusual source and the groundbreaking technique used to produce the image are detailed in a letter published today in Astronomy & Astrophysics. The paper, "Global e-VLBI observations of the gamma-ray narrow line Seyfert 1 PMN J0948+0022" (abstract, full html, PDF), presents very...

Continent-wide telescope extends cosmic 'yardstick' three times farther into universe Using the super-sharp radio "vision" of astronomy's most precise telescope, scientists have extended a directly-measured "yardstick" three times farther into the cosmos than ever before, an achievement with important implications for numerous areas of astrophysics, including determining the nature of Dark Energy, which constitutes 70 percent of the Universe. The continent-wide Very Long Baseline Array (VLBA)...

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...
