The most distant jet ever observed was discovered in an image of a quasar made by NASA’s Chandra X-ray Observatory.
Extending more than 100,000 light-years from the supermassive black hole powering the quasar, the jet of high-energy particles provides astronomers with information about the intensity of the cosmic microwave background radiation 12 billion years ago.
More than 150 researchers from across Europe, Canada, the United States, China and as far away as Chile have come together to recount their many and varied uses of a single instrument a desk-sized camera called MERIS, hurtling through space aboard Envisat at more than seven kilometres per second.
A nurse holds a strange-looking device, moving it slowly toward a young patient’s face. The note-card-sized device is covered with glowing red lights, but as it comes closer, the youngster shows no fear. He’s hopeful this painless procedure using an array of lights will help ease or prevent some of the pain and discomfort associated with cancer treatment.
The UO-14 Amateur Radio satellite has been declared officially dead after nearly 14 years in orbit, the Mission Control Centre at the Surrey Satellite Technology Ltd (SSTL) Center for Satellite Engineering Research reported November 11. AMSAT-UK Chairman Martin Sweeting, G3YJO, said one of the NiCad battery cells became exhausted, which caused UO-14’s transmitter to shut down due to undervoltage.
The popular and heavily used FM satellite quit working in August. Ground controller Chris Jackson, G7UPN, was able to reset the satellite at one time, but he later determined that UO-14 had suffered a primary power system failure.
NASA’s Langley Research Center visitor center in Hampton, Va., is celebrating the centennial of flight by unveiling a new state-of-the-art, interactive gallery. The one million-cubic-foot “Adventures in Flight” in the Virginia Air & Space Center (VASC) chronicles the history of aviation, and NASA’s contributions to flight.
Europe’s mission to the Red Planet, Mars Express, is on schedule to arrive at the planet on Christmas Day, 2003.
What is the next best thing to humans landing on Mars and exploring the wonders of the Red Planet? The answer: touching, imaging and analysing carefully preserved samples of Martian rock in a state-of-the-art laboratory on Earth
Newly seen details in a fan-shaped apron of debris on Mars may help settle a decades-long debate about whether the planet had long-lasting rivers instead of just brief, intense floods.
Pictures from NASA’s Mars Global Surveyor orbiter show eroded ancient deposits of transported sediment long since hardened into interweaving, curved ridges of layered rock. Scientists interpret some of the curves as traces of ancient meanders made in a sedimentary fan as flowing water changed its course over time.
ESA’s gamma-ray observatory Integral is making excellent progress, mapping the Galaxy at key gamma-ray wavelengths.
ESA’s Envisat satellite was witness to the dramatic last days of what was once the world’s largest iceberg, as a violent Antarctic storm cracked a 160-km-long floe in two.
