Interstellar EmDrive gets boost from new theory of inertia
May 02, 2016 (Sputnik)
A researcher from the UK has put forward a theory for how the EmDrive, an electromagnetic propulsion drive, might work, a question which has puzzled scientists ...
Physicists detect the enigmatic spin momentum of light
Apr 29, 2016 (SPX)
Ever since Kepler's observation in the 17th century that sunlight is one of the reasons that the tails of comets to always face away from the sun, it has been u...
Fermi Telescope helps link cosmic neutrino to blazar blast
Apr 29, 2016 (SPX)
Nearly 10 billion years ago, the black hole at the center of a galaxy known as PKS B1424-418 produced a powerful outburst. Light from this blast began arriving ...
Superfast light source made from artificial atom
Apr 29, 2016 (SPX)
All light sources work by absorbing energy - for example, from an electric current - and emit energy as light. But the energy can also be lost as heat and it is...
New nanodevice shifts light's color at single-photon level
Apr 25, 2016 (SPX)
Converting a single photon from one color, or frequency, to another is an essential tool in quantum communication, which harnesses the subtle correlations betwe...
Herschel captures galactic panorama of the Milky Way
Apr 25, 2016 (ESA)
This new video from ESA's Herschel space observatory reveals in stunning detail the intricate pattern of gas, dust and star-forming hubs along the plane of our ...
Cosmic beacons reveal the Milky Way's ancient core
Apr 25, 2016 (SPX)
An international team of astronomers led by Dr. Andrea Kunder of the Leibniz Institute for Astrophysics Potsdam (AIP) in Germany has discovered that the central...
Dark matter does not contain certain axion-like particles
Apr 25, 2016 (SPX)
Researchers at Stockholm University are getting closer to corner light dark-matter particle models. Observations can rule out some axion-like particles in the q...
Microscopic 'clocks' time distance to source of galactic cosmic rays
Apr 22, 2016 (SPX)
Most of the cosmic rays arriving at Earth from our galaxy come from nearby clusters of massive stars, according to new observations from the Cosmic Ray Isotope ...
Nearby supernova ashes continue to rain on Earth
Apr 22, 2016 (SPX)
Traces of 60Fe detected in space indicate that a nearby supernova occurred within the last few million years. The iron isotope 60Fe, which is very rare, is crea...
Microscopic 'timers' reveal likely source of galactic space radiation
Apr 22, 2016 (SPX)
Most of the cosmic rays that we detect at Earth originated relatively recently in nearby clusters of massive stars, according to new results from NASA's Advance...
HAWC Gamma-Ray Observatory's reveals the very-high-energy sky
Apr 20, 2016 (SPX)
The United States and Mexico constructed the High Altitude Water Cherenkov (HAWC) Gamma-ray Observatory to observe some of the most energetic phenomena in the k...
Inside the fiery furnace
Apr 18, 2016 (SPX)
Galaxies, it seems, are sociable animals and they like to gather together in large groups, known as clusters. Actually it's gravity that holds the galaxies in t...
Hidden galaxy found in ALMA gravitational lens image
Apr 18, 2016 (SPX)
Researchers have uncovered the existence of a dwarf "dark galaxy" lurking nearly 4 billion light-years away from Earth. The discovery was made when a team of re...
Probing the transforming world of neutrinos
Apr 18, 2016 (SPX)
Every second, trillions of neutrinos travel through your body unnoticed. Neutrinos are among the most abundant particles in the universe, but they are difficult...
A Space Spider Watches Over Young Stars
Apr 18, 2016 (JPL)
A nebula known as "the Spider" glows fluorescent green in an infrared image from NASA's Spitzer Space Telescope and the Two Micron All Sky Survey (2MASS). The S...
Calcium isotope holds the secret to the mass of neutrinos
Apr 15, 2016 (SPX)
Scientists around the world are being kept in suspense by the negligible mass of neutrinos, subatomic particles that could be matter and antimatter at the same ...
New hypervelocity binary star challenges dark matter, stellar acceleration models
Apr 15, 2016 (SPX)
A team of astronomers at the Friedrich Alexander University led by Peter Nemeth has discovered a binary star moving nearly at the escape velocity of our galaxy....
Are cosmic rays the key to galaxy formation
Apr 14, 2016 (SPX)
The new Junior Research Group "High Energy Astrophysics and Cosmology" (HAC) has now started at the Heidelberg Institute for Theoretical Studies (HITS). HITS as...
The Missing Brown Dwarfs
Apr 13, 2016 (SPX)
When re-analysing catalogued and updated observational data of brown dwarfs in the solar neighbourhood, astronomers from Potsdam have found that a significant n...
