Using the Neutron Star Interior Composition Explorer (NICER) onboard the International Space Station (ISS), an international team of astronomers has inspected the recent outburst of an accreting millisecond X-ray pulsar known ...
Indian astronomers have performed long-term radio observations of a "black widow" millisecond pulsar known as PSR J1544+4937. Results of the observational campaign, published November 25 on the arXiv pre-print server, shed ...
European astronomers have conducted X-ray and optical observations of a transitional millisecond pulsar known as PSR J1023+0038. Results of the observational campaign, published November 23 on arXiv.org, yield important insights ...
Looking like a glittering swarm of buzzing bees, the stars of globular cluster NGC 6440 shine brightly in this NASA Hubble Space Telescope image. The cluster is located some 28,000 light-years away in the constellation Sagittarius, ...

Astronomers report the detection of four new pulsars using the Giant Metrewave Radio Telescope (GMRT) as part of the GMRT High Resolution Southern Sky (GHRSS) survey. The finding was detailed in a research paper published ...
All stars, including the sun, have a finite lifetime. Stars shine by the process of nuclear fusion in which lighter atoms, such as hydrogen, fuse together to create heavier ones. This process releases vast quantities of energy ...

Indian astronomers have employed NASA's NuSTAR spacecraft to inspect an X-ray pulsar known as 1E 1145.1-6141. Results of the observations deliver important insights into the properties and nature of this pulsar. The study ...
Pulsar signals obtained with radio telescopes are extremely weak. Generally, there are two primary difficulties in pulsar signal processing—one is the radio-frequency interference (RFI) mitigation, and the other one is ...
