Satellite gives a new view of pulsars
Observations of old pulsars by the European Space Agency’s XMM-Newton satellite fail to detect the 1 million-degree hot spots seen around the pole of younger pulsars. The absence of polar X...

Neutrinos provide new route to heavy elements in supernovae
During their long lifetimes stars generate their energies by nuclear fusion in their interiors, which are generally accepted to be the breeding grounds for carbon and heavier elements.

HESS helps lift the fog in intergalactic space
Observations of very high-energy gamma-rays from two distant active galaxies reveal that the universe is more transparent to this radiation than previously thought. This limited absorption of gamma-ra...

Sterile neutrinos unravel astrophysics
Almost every current theoretical model of neutrino masses introduces sterile ("right-handed") fields, which mix with the ordinary ("left-handed") neutrinos.
