“The predominant theory says that jets are essentially fire hoses that shoot out matter in a steady stream, and the stream breaks up as it collides with gas…
In conjunction with Galileo's birthday on Feb. 15, NASA is releasing images from its Great Observatories — the Hubble Space Telescope, Spitzer Space…
Kawaler, an Iowa State University professor of physics and astronomy, plans to celebrate the new research program by witnessing the mission’s launch in early…
The Cosmic Dawn began as galaxies began to form out of the debris of massive stars which died explosively shortly after the beginning of the Universe. The…
“At times, this remarkable object has erupted with more than a hundred flares in as little as 20 minutes,” said Loredana Vetere, who is coordinating the Swift…
The researchers drove semiconducting carbon nanotubes into an avalanche process that carries more electrons down more paths, similar to the way a multilane…
On 6 February, ESA reviewed the status of the spacecraft and the results of the test campaigns that were carried out over the past year. Following the review,…
Astronomers today celebrated the formal acceptance of the first North American antenna by the Joint ALMA Observatory. ALMA, the Atacama Large…
“We not only do not know what the stuff is, but we do not know where it is made or how it gets into space,” said Donald York, the Horace B. Horton Professor in…
The images unravel some of the inner workings of the most efficient solar energy process on earth – photosynthesis. Inside a photosynthetic protein, the sun's…
These results are significant in the understanding of QD behavior and scientists' ability to utilize QDs in active devices or for information processing. The…
Future telescopes, with mirrors half the size of a football field, will need special components to deal with the light they collect. Astronomers are turning to…
The method also might be used for detecting fatigue in materials such as carbon-fiber plastics used to build the latest generation of aircraft fuselages, tails…
When galaxies are born, do their stars form everywhere at once, or only within a small core region? Recent measurements of an international team led by…
“The new device is capable of controlling both the plasma conduction current and the light emission with an emitter voltage of 5 volts or less,” said Gary…
Cardiff University researchers who are part of a British-German team searching the depths of space to study gravitational waves, may have stumbled on one of…
