Mysterious X-ray signal intrigues astronomers
(Phys.org) —A mysterious X-ray signal has been found in a detailed study of galaxy clusters using NASA's Chandra X-ray Observatory and ESA's XMM-Newton. One intriguing possibility is that the X-rays are ...
New study suggests more and longer atmospheric stagnation events due to global warming
Le Mans: Nissan ZEOD praised for run on electric power
Researchers predict global warming will cause an increase in frequency of Indian Ocean Dipole events
Surprisingly strong magnetic fields challenge black holes' pull
A new study of supermassive black holes at the centers of galaxies has found magnetic fields play an impressive role in the systems' dynamics. In fact, in dozens of black holes surveyed, the magnetic field ...
Astronomers harness the galaxy's biggest telescope to make most precise measurement of spinning star
(Phys.org) —An international team of astronomers has made a measurement of a distant neutron star that is one million times more precise than the previous world's best.
Stimulated mutual annihilation: How to make a gamma-ray laser with positronium
Twenty years ago, Philip Platzman and Allen Mills, Jr. at Bell Laboratories proposed that a gamma-ray laser could be made from a Bose-Einstein condensate (BEC) of positronium, the simplest atom made of both ...
Researchers find carbon reactions with basalt can form carbonate minerals faster than thought
Study casts doubt on climate benefit of biofuels from corn residue
Using corn crop residue to make ethanol and other biofuels reduces soil carbon and can generate more greenhouse gases than gasoline, according to a study published today in the journal Nature Climate Change.
Mysterious source of ozone-depleting chemical baffles NASA
A chemical used in dry cleaning and fire extinguishers may have been phased out in recent years but NASA said Wednesday that carbon tetrachloride (CCl4) is still being spewed into the atmosphere from an unknown ...
How the Asian monsoon affects methane emissions
(Phys.org) —Scientists at the University of Bristol's Cabot Institute have shown how changes in the Asian monsoon affected emissions of methane, a prominent greenhouse gas, from the Tibetan Plateau.
Why global warming is taking a break
The average temperature on Earth has barely risen over the past 16 years. ETH researchers have now found out why. And they believe that global warming is likely to continue again soon.
Follow the radio waves to exomoons, astrophysicists say
Scientists hunting for life beyond Earth have discovered more than 1,800 planets outside our solar system, or exoplanets, in recent years, but so far, no one has been able to confirm an exomoon. Now, physicists ...
