An ingenious technique could enable us to witness some of the strongest gravitational waves.
It’s small but it will rip you apart using only magnetism.
A novel mathematical model can weigh the mass of a pulsar – a rapidly rotating magnetized neutran star – using principles of nuclear physics, rather than gravity. Up until now, the mass of a star could only be determined in relation with other bodies, based on the gravitational pull these exerted. Now, using the new model scientists will be able to study pulsars in isolation, allowing for more precise measurements than ever before.
Scientists have observed a massive burst of radio waves, helping them narrow down the potential sources of these huge bursts of energy. These events, also called blitzars, last about a millisecond but give off as much energy as the sun does in a million years. These are quite possibly the most interesting and shocking sources of energy in the Universe. It’s
Pulsars and black holes, two of the most enigmatic celestial bodies in the Universe may actually hold the key to understanding how Einstein’s theory of relativity and gravity interact. A pulsar is a highly magnetized, rotating neutron star that emits a beam of electromagnetic radiation. Pulsars are from when a star that turns becomes a supernova and then collapses into a neutron star;
It’s a good day for crowdsourcing – the Einstein@Home project, which connects home and office PCs of volunteers from around the world to a global supercomputer announced that through the participation of volunteers alone, astronomers were able to discover 24 new pulsars. That’s right, you can do top notch science, from your very own home… without actually doing anything. Einstein@Home
In case you’re wondering, the biggest ‘guitar’ in our galaxy is in fact a pulsar that was nicknamed The Guitar Pulsar. It’s basically a stellar corpse that emits a beam of electromagnetic radiation that just shreds interstellar gas, creating a wake of hot hydrogen shaped just like a guitar. Little is known about these remnants, from any point of view.
Recently, NASA’s Fermi Gamma-ray Space Telescope discovered no more, no less than 12 pulsars, and it also detected gamma ray pulse from 18 others. These findings are forcing scientists to rethink what we know about dying stars, as they totally underestimated the power of these stellar cilinders. “We know of 1,800 pulsars, but until Fermi we saw only little wisps
