A higher repetition rate is also key to using a high - power laser to drive beams of particles. (sciencemag.org)
Instead of a black hole, it left behind a rotating neutron star, or pulsar, that spins 30 times a second and shoots beams of particles from its poles. (discovermagazine.com)
One dramatic consequence is that some of the star's material, stripped from the star and collected around the black hole, can be ejected in extremely narrow beams of particles at speeds approaching the speed of light. (sciencedaily.com)
