The repeated explosions from the recurrent nova RS Ophiuchi (RS Oph) provide favorable environments for accelerating protons to very high energies, a new international study reports. The results ...

A small, dense star chowing down on its enormous dying neighbor caused a massive explosion that generated some of the highest-energy gamma-rays ever observed for a nova. The nova system, called RS ...

A group of scientists recently observed a massive nova explosion they say pushed particles to their theoretical speed limit. The eruption came from a burned-out stellar core in the system RS Ophiuchi ...

(CN) — A team of German astronomers has recorded the gamma radiation from a dramatic explosion deep in space, using two telescopes in Spain. Roughly 5,000 light-years away from Earth, RS Ophiuchi is a ...

Scientists have found that a nearby two-star system contains a precursor to a Type Ia supernova, an important class of star explosions used to measure the expansion rate of the universe. The ...

Artist’s impression of the RS Ophiuchi binary star system, which is comprised of a white dwarf (background) and red giant that orbit each other. Material from the red giant is continually accreted by ...
