Binary star system precisely timed with pulsar's gamma-rays
Pulsars are rapidly rotating compact remnants born in the explosions of massive stars. They can be observed through their lighthouse-like beams of radio waves and gamma-rays. Scientists at the Max Planck Institute for Gravitational ...

Millisecond pulsars
When a star with a mass of roughly ten solar masses finishes its life, it explodes as a supernova, leaving behind a neutron star as remnant "ash." Neutron stars have masses of one-to-several suns but they are tiny in diameter, ...

Saturday Citations: Adorable kittens, violent pulsars, brand-new fusion reactor and a proposed giant cosmic void
This week in our wrap up, we lull you into a false sense of security with adorable lion cubs then ambush you with terrifying pulsars. We do this not out of a sense of malice but to prepare your mind for the possibility of ...
Astronomers discover a rare 'black widow' binary, with the shortest orbit yet
The flashing of a nearby star has drawn MIT astronomers to a new and mysterious system 3,000 light years from Earth. The stellar oddity appears to be a new "black widow binary"—a rapidly spinning neutron star, or pulsar, ...

Slowest-spinning radio pulsar detected by astronomers
An international team of astronomers has discovered a new radio pulsar as part of the LOFAR Tied-Array All-Sky Survey (LOTAAS). The newly detected object, designated PSR J0250+5854, turns out to be the slowest-spinning radio ...
Amateur astronomer helps uncover secrets of unique pulsar binary system
A professional astrophysicist and an amateur astronomer have teamed up to reveal surprising details about an unusual millisecond pulsar (MSP) binary system comprising one of the fastest-spinning pulsars in our Galaxy and ...
