Using the MeerKAT radio telescope, an international team of astronomers has observed a Galactic globular cluster known as NGC 6522. As a result, they have discovered two new isolated pulsars in this cluster. The finding is ...
(PhysOrg.com) -- The Crab Nebula is the remnant of a supernova. Its precursor star exploded in 1054 AD in an event that was recorded by Chinese and (quite probably) Anasazi Indian astronomers. It is called the Crab Nebula ...

Using the MeerKAT radio telescope, an international team of astronomers has detected 13 new pulsars in the globular cluster NGC 1851. Twelve of them turned out to be millisecond pulsars (MSPs). The discovery was reported ...
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, ...
(PhysOrg.com) -- NASA's Fermi Gamma-ray Space Telescope has discovered 12 new gamma-ray-only pulsars and has detected gamma-ray pulses from 18 others. The finds are transforming our understanding of how these stellar cinders ...

Using the Parkes radio telescope, Chinese astronomers have investigated an isolated pulsar known as PSR J1047−6709 and detected dozens of giant pulses during the bright state of this source. The finding is reported in a ...
While the scientific community grapples with the loss of the Arecibo radio telescope, astronomers who recently revived a long-dormant radio telescope array in Argentina hope it can help modestly compensate for the work Arecibo ...
