New mechanism of radio emission in neutron stars released

Young scientists from ITMO University have explained how neutron stars generate intense directed radio emission. They developed a model based on the transitions of particles between gravitational states, i.e. quantum states ...

The gamma ray burst – supernova connection

A "core-collapse" supernova occurs when the iron core of a massive star collapses under the force of gravity and then rebounds, generating pressure waves and shocks that propagate outward. A superluminous supernovae is a ...

Dead star circled by light

New images from ESO's Very Large Telescope and other telescopes reveal a rich landscape of stars and glowing clouds of gas in one of our closest neighboring galaxies, the Small Magellanic Cloud. The pictures have allowed ...

Understanding fast radio bursts

Astronomers are detecting a mysterious, powerful form of radiation blipping across space, and nobody's quite sure why.

Measuring white dwarf masses with gravitational lensing

Measuring the mass of a celestial body is one of the most challenging tasks in observational astronomy. The most successful method uses binary systems because the orbital parameters of the system depend on the two masses. ...

Donor star breathes life into zombie companion

ESA's Integral space observatory has witnessed a rare event: the moment that winds emitted by a swollen red giant star revived its slow-spinning companion, the core of a dead star, bringing it back to life in a flash of X-rays.
