Astronomers have witnessed a never-seen-before event in observations by ESA’s XMM-Newton spacecraft – a collision between a pulsar and a ring of gas around a neighbouring star. The rare passage, which ...
Down a seldom traveled side road an hour south of Buenos Aires, two half century old 30-meter single dish radio antennas are pointed upward. Separated by only 120 meters (about the size of a soccer ...
Astronomers have uncovered the strange case of a neutron star with the peculiar ability to transform from a radio pulsar into an X-ray pulsar and back again. This star’s capricious behavior appears to ...
Neutron stars are some of the most extreme objects in the universe. Formed from the collapsed cores of supergiant stars, they weigh more than our Sun and yet are compressed into a sphere the size of a ...

Pulsars to the extreme: Spinning dead stars found blasting radio signals from their edges
Astronomers have discovered that rapidly spinning dead stars called neutron stars at the heart of pulsars can blast out radio signals from their edges. The finding could overturn decades of thinking ...
Astronomers have spotted a rare cosmic duo: a neutron star that rotates nearly a hundred times every second locked in an ultra-tight orbit with a semi-shredded star. The scientists who found the pair ...
About 2,600 light-years away, a dead star is sending signals from beyond the grave. Astronomers recently found the strange beacon, which appears to be a pulsar blinking in slow motion — something that ...
