Today's science news is bookended by two NASA missions: one racing against orbital decay to rescue a 22-year-old telescope, another reclassifying a Milky Way relic. Meanwhile, the theoretical physics beat offers a meditation on black holes and time travel, and a new Alzheimer's screening method emerges from retinal imaging.
Two NASA stories dominate: a daring rescue mission and a surprising reclassification of a star cluster.
NASA is attempting an unprecedented robotic rescue of the Swift Observatory, whose orbit is decaying; if it fails, the telescope could burn up by year's end.
Webb and Hubble data reveal Terzan 5 is not a simple globular cluster but a complex system with multiple star populations, offering clues to galaxy formation.
Chandra's 14-year study of M83 found supernova remnants behaving like fireworks, with half showing dramatic brightness changes, unexpected for slowly fading debris.
From black hole time travel to early Alzheimer's detection, today's pieces push boundaries.
A Scientific American piece explores whether black holes could enable backward time travel via closed timelike curves, mixing theory with a thought experiment.
Retinal imaging may predict Alzheimer's risk years before symptoms, offering a non-invasive early detection tool based on the retina's connection to brain tissue.
