Using the MeerKAT radio telescope, European astronomers have serendipitously discovered a new radio nebula during observations of the black hole binary GRS 1915+105. The newfound object, dubbed "the Mini Mouse," is a young ...
Astronomers have investigated an ultraslow radio pulsar known as PSR J0901-4046, finding that it has an extremely high magnetic field—at a level of 30 quadrillion Gauss. The discovery, published April 7 in Physical Review ...
On Feb. 22, 1971, a sounding rocket lifted off from Wallops Island, Virginia, with specialized sensors aimed at the Crab Nebula, a bright cosmic object 6,500 light-years away. In those days, before recovering physical tapes ...

Using the Australia Telescope Compact Array (ATCA), astronomers from Hong Kong and Australia have performed radio observations of a nearby pulsar wind nebula (PWN) powered by the pulsar PSR B1706−44. Results of the study, ...
Using various space telescopes, astronomers have performed X-ray observations of a radio pulsar known as PSR J1420−6048. Results of the observational campaign, published January 27 on the arXiv pre-print server, shed more ...
If you want to know where you are in space, you'd better bring along a map. But it's a little more complicated than riding shotgun on a family road trip.

Pulsars are highly magnetized, rotating neutron stars that emit a beam of electromagnetic radiation. The observed periods of their pulses range from 1.4 milliseconds to 8.5 seconds. The radiation can only be observed when the beam of emission is pointing towards the Earth. This is called the lighthouse effect and gives rise to the pulsed nature that gives pulsars their name. Because neutron stars are very dense objects, the rotation period and thus the interval between observed pulses are very regular. For some pulsars, the regularity of pulsation is as precise as an atomic clock. Pulsars are known to have planets orbiting them, as in the case of PSR B1257+12. Werner Becker of the Max Planck Institute for Extraterrestrial Physics said in 2006, "The theory of how pulsars emit their radiation is still in its infancy, even after nearly forty years of work."
