Across a distance of 650 light-years, the Helix Nebula has quietly held a secret for more than four decades — an unexplained pulse of X-ray light emanating from a stellar corpse at its heart. New observations from NASA's Chandra and ESA's XMM-Newton now suggest that rhythmic signal is the dying echo of a Jupiter-sized world being torn apart and consumed by a white dwarf, marking what may be the first witnessed act of planetary destruction within a planetary nebula. In solving this long-standing mystery, astronomers find themselves peering not only into a distant past, but into a possible futur
