Researchers say galaxy may swarm with 'nomad planets'
(PhysOrg.com) -- Our galaxy may be awash in homeless planets, wandering through space instead of orbiting a star.
Hubble finds birth certificate of oldest known star
(Phys.org) —A team of astronomers using NASA's Hubble Space Telescope has taken an important step closer to finding the birth certificate of a star that's been around for a very long time.
Physicists control quantum tunneling with light for the first time
Scientists at the Cavendish Laboratory in Cambridge have used light to help push electrons through a classically impenetrable barrier. While quantum tunnelling is at the heart of the peculiar wave nature of particles, this ...
Antihelium-4: Physicists nab new record for heaviest antimatter
(PhysOrg.com) -- Members of the international STAR collaboration at the Relativistic Heavy Ion Collider -- a particle accelerator used to recreate and study conditions of the early universe at the U.S. Department ...
Radioactive decay rates vary with the sun's rotation: research
Radioactive decay rates, thought to be unique physical constants and counted on in such fields as medicine and anthropology, may be more variable than once thought.
Oxygen nucleus with twice as many neutrons as normal is shown to be surprisingly stable
The nucleus at the heart of an atom is held together by a subtle balance between the nuclear force that binds protons and neutrons and the electric repulsion that tries to fling the positively charged protons ...
Research concludes there is no 'simple theory of everything' inside the enigmatic E8
The "exceptionally simple theory of everything," proposed by a surfing physicist in 2007, does not hold water, says Emory University mathematician Skip Garibaldi.
Silver tells a volatile story of Earth's origin: Water was present during its birth
Tiny variations in the isotopic composition of silver in meteorites and Earth rocks are helping scientists put together a timetable of how our planet was assembled beginning 4.568 billion years ago. The new ...
First measurement of magnetic field in Earth's core
(PhysOrg.com) -- A University of California, Berkeley, geophysicist has made the first-ever measurement of the strength of the magnetic field inside Earth's core, 1,800 miles underground.
Researchers recalculate age of Solar System
(PhysOrg.com) -- Lead-lead (Pb-Pb) dating is among the most widely used radiometric dating techniques to determine the age of really old things, such as the age of the Earth or the Solar System. However, recent ...
Lunar Reconnaissance Orbiter spectrometer detects helium in Moon's atmosphere
(Phys.org) -- Scientists using the Lyman Alpha Mapping Project (LAMP) aboard NASA's Lunar Reconnaissance Orbiter have made the first spectroscopic observations of the noble gas helium in the tenuous atmosphere ...
How slow is slow? EXO knows
(PhysOrg.com) -- Cooks think of watched pots. Handymen grumble about drying paint. Kids dread the endless night before Christmas morning.
Radioactive decay of titanium powers supernova remnant
(Phys.org)—The first direct detection of radioactive titanium associated with supernova remnant 1987A has been made by ESA's Integral space observatory. The radioactive decay has likely been powering the ...
Precision measurement of W boson mass portends stricter limits for Higgs particle
(PhysOrg.com) -- Scientists of the DZero collaboration at the Department of Energy's Fermi National Accelerator Laboratory have achieved the world's most precise measurement of the mass of the W boson by a ...
