Astronomers use JWST to peer into the heart of the Crab Nebula

Scientific papers rarely have images this spectacular in them.

Cosmic 'cannonballs' may explain mystery of fast-switching pulsar

Astronomers illuminate strange pulsar behavior.

Einstein's Theory of General Relativity aces its toughest test yet in 16-year-old study of unique pulsar system

Scientists hoped to find a deviation from this landmark theory. But general relativity proves yet again to be one tough nut to crack.

Astronomers map the surface of a pulsar for the first time

A new mapped the surface of a pulsar, and it may cause astronomers to rewrite their textbooks.

Peculiar pulsar slows down before 'glitching'

The findings might help astronomers unravel the dynamics inside neutron stars.

She lost the Nobel Prize to her supervisor in 1974 -- now, she got a $3 million physics prize, and donated all of it

The pioneering physicist gave all the prize money away.

Astronomers are on the lookout for low-frequency gravitational waves generated by merging supermassive black holes

An ingenious technique could enable us to witness some of the strongest gravitational waves.

Astronomers discover the first white dwarf pulsar in history, ending half a century of searching

It's small but it will rip you apart using only magnetism.

How to weigh a star: a new mathematical method

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 Observe Giant Burst of Radio Waves

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 […]

Pulsars with black holes could hold the 'holy grail' of gravity

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 […]

Nasa discovers a dozen pulsars that change understanding about dying stars

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 […]
