This area deals with the fundamental laws and building blocks of nature and how they interact, the properties and the behavior of matter, and research into space and time and their structures.
innovations-report provides in-depth reports and articles on subjects such as astrophysics, laser technologies, nuclear, quantum, particle and solid-state physics, nanotechnologies, planetary research and findings (Mars, Venus) and developments related to the Hubble Telescope.
For the last few years evidence that we are living on a very “weird” universe has been growing: the expansion of the universe is accelerating, and one theory proposed to account for this acceleration is what has been termed “dark energy.”
In order to find out what this mysterious energy really is, astronomers need to compare astrophysical observations that are at first sight completely unrelated. At a session on dark energy at the Annual Meeting of the American Association for
Distributed computing project to search for gravitational waves.
A new grassroots computing project dubbed Einstein@Home, which will let anyone with a personal computer contribute to cutting edge astrophysics research, will be officially announced at the annual meeting of the American Association for the Advancement of Science (AAAS) in Washington DC on Saturday, February 19. LIGO Laboratory Director Barry Barish of Caltech and Einstein@Home Principal Investigator Bruce Allen
Cassini-Huygens supplied new evidence about why Titan has an atmosphere, making it unique among all solar system moons, a University of Arizona planetary scientist says.
Scientists can infer from Cassini-Huygens results that Titan has ammonia, said Jonathan I. Lunine, an interdisciplinary scientist for the European Space Agencys Huygens probe that landed on Titan last month. “I think whats clear from the data is that Titan has accreted or acquired significant amounts
Astronomers around the world recorded late last year the brightest explosion ever of high-energy X-rays and gamma rays – a split-second flash from the other side of our galaxy that was strong enough to affect the Earth’s atmosphere.
The flash, called a soft gamma repeater flare, reached Earth on Dec. 27 and was detected by at least 15 satellites and spacecraft between Earth and Saturn, swamping most of their detectors. Some of the best observations were recorded by the Reuven
Advanced computational methods and supporting experiments, including work performed at the Department of Energys Oak Ridge National Laboratory, are giving scientists a better understanding of the nature and stability of superheavy nuclei and the heaviest elements that lie beyond the borders of the periodic table.
Nature magazine on Thursday published a review article that describes collaborative work by researchers at Oak Ridge National Laboratory and the University of Te
Earth is showered constantly by particles called muons that are created by cosmic rays, and clever scientists are finding ways to use them as probes of dense objects, including a massive pyramid in Mexico and volcanoes in Japan. American researchers also have proposed using the energetic particles to detect smuggled nuclear materials in vehicles and cargo containers.
Muons are formed when cosmic rays from deep space interact with the atmosphere. The particles, which strike earth
