XRISM’s Resolve spectrometer measured shifted iron absorption lines in a binary star system. The spectrum indicates gas moving toward an orbiting neutron star at about 335,000 miles per hour. Researchers interpret the captured companion-star wind as feeding bright X-ray flares. The observation lasted about 16 hours near the end of one flare; the inward-flow animation is an interpretation, not a direct image. The peer-reviewed result appeared in *Science Advances* on September 18, 2026.
