The earliest definitions of time and time-interval quantities were based on observed astronomical phenomena, such as apparent solar or lunar time, and as such, time as measured by clocks, and frequency, as measured by devices ...
The Center for Computational Astrophysics (CfCA) of the National Astronomical Observatory of Japan upgraded the supercomputer Cray XC30 system "ATERUI". By introducing state-of-the-art CPUs, the theoretical peak performance ...
(Phys.org) —For only the second time in history, a team of scientists—including Carnegie's Michele Fumagalli—have discovered an extremely rare triple quasar system. Their work is published by Monthly Notices of the ...
(Phys.org)—NASA's Nuclear Spectroscopic Telescope Array, or NuSTAR, set its X-ray eyes on a spiral galaxy and caught the brilliant glow of two black holes lurking inside.
(Phys.org)—On the evening of 13 and the morning of 14 December, skywatchers across the world will be looking up as the Geminid meteor shower reaches its peak, in potentially one of the best night sky events of the year.
A research team of the Department of Physics, Keio University, has discovered a molecular cloud with a peculiar helical structure by observation with the NRO 45m Telescope at Nobeyama Radio Observatory, National Astronomical ...
(PhysOrg.com) -- A University of Toronto-led team of astronomers has observed extreme brightness changes on a nearby brown dwarf that may indicate a storm grander than any seen yet on a planet. Because old brown dwarfs and ...
(PhysOrg.com) -- Certain stars stream vast amounts of matter into space, creating some of the most beautiful objects in astronomers' telescopes. But while the astronomers can enjoy the beauty, they can't explain it. Adam ...
(PhysOrg.com) -- Solar flares are amongst the most dangerous cosmic phenomena man has ever known. Though they pose no harm to humans, their effect on technology is vast. When they occur, they possess the capability to knock ...
Even Albert Einstein might have been impressed. His theory of general relativity, which describes how the gravity of a massive object, such as a star, can curve space and time, has been successfully used to predict such astronomical ...
