Astronomers Discover PSR J1544-2555: A Rare Black Widow Millisecond Pulsar A newly identified "spider" millisecond pulsar, named PSR J1544-2555 , has been detected by an international team of astronomers. This remarkable finding, published in a research paper on arXiv on 11 September , provides fresh insights into one of the most intriguing classes of neutron stars. Millisecond pulsars (MSPs) are the fastest known cosmic clocks, spinning hundreds of times each second. The discovery of PSR J1544-2555 not only expands our understanding of pulsar families but also emphasizes the value of optical and gamma-ray surveys in uncovering hidden celestial objects.
