The sweeping beams of cosmic lighthouses called pulsars are much more energetic than previously thought, calling into question the bulbs that power them. A new analysis, from the High Energy ...

The surprising detection of light 200 times more powerful than previous observations from the nearby pulsar Vela indicates hidden physics around dead stars. When you purchase through links on our site ...

Astronomers have discovered an extraordinary celestial system containing a runaway pulsar fleeing the scene of a massive stellar supernova explosion. What makes this system even more spectacular is ...

Astronomers used the Arecibo Observatory in Puerto Rico to spot pulses that travelled faster than the speed of light. Every physicist is taught that information cannot be transmitted faster than the ...

Astronomers have added a new species to the neutron star zoo, showcasing the wide diversity among the compact magnetic remains of dead, once-massive stars. While it’s an oddball, some of this newfound ...

Science advances through data that don't fit our current understanding. At least that was Thomas Kuhn's theory in his famous On the Structure of Scientific Revolutions. So scientists should welcome ...

When it comes to the future of space travel, nothing exceeds like excess. Pulsar Fusion hopes to demonstrate that axiom with its planned Sunbird nuclear fusion rocket, which is designed to travel at ...

Space propulsion company Pulsar Fusion has started construction on a large nuclear fusion chamber in England, as it races to become the first firm to fire a nuclear fusion-powered propulsion system in ...
