Until recently, there were only ten known stars on trajectories that will allow them to escape the Milky Way galaxy, thrown astray by powerful supernova explosions. A new study using data from ESA's Gaia survey this June ...

An international team of astronomers has analyzed the data from the latest phase of the Sloan Digital Sky Survey (SDSS). They discovered eight new cataclysmic variables (CV) systems. The finding is reported in a paper published ...
Fast radio bursts—intense, milliseconds-long flashes of radio energy from outer space—have puzzled astronomers since they were first spotted in 2007. A single burst can emit as much energy in its brief life as the Sun ...

We're building the tools to trap ions and watch them glow (or not). The art-deco-esque device shown above is a combined trap for ions (charged atoms) and detector for individual photons (particles of light). When you hold ...

By analyzing the data from the Hubble Space Telescope (HST), astronomers from the University of Bologna in Italy and elsewhere have found that the millisecond pulsar PSR J1835−3259B has a young white dwarf companion. The ...
A white dwarf star can explode as a supernova when its mass exceeds the limit of about 1.4 solar masses. A team led by the Max Planck Institute for Extraterrestrial Physics (MPE) in Garching and involving the University of ...
