"Scientists Confirm Existence of Missing Link in Spider Pulsars Theory"

Astronomers using the Five-hundred-meter Spherical radio Telescope (FAST) have discovered a binary pulsar system, known as PSR J1953+1844 or M71E, with an orbital period of only 53 minutes. This finding fills a gap in our understanding of the evolutionary stages of spider pulsar systems, confirming the theory of their evolution from redback to black widow states. The discovery was made possible by the unprecedented sensitivity of FAST, the world's largest and most sensitive radio telescope.
