Nasa's Rossi X-ray Timing Explorer leaves scientific legacy

NASA's decommissioned Rossi X-ray Timing Explorer (RXTE) satellite re-entered Earth's atmosphere on April 30. Orbiting for more than 22 years, the 6,700-pound satellite operated from 1996 to 2012, providing scientists with ...

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 ...
