NASA's SPHEREx mission caught it erupting two months after perihelion, ejecting water, organics (methanol, cyanide, methane), and BB-sized rocky chunks as solar heat finally penetrated to its subsurface ice. After a close encounter with Jupiter in March 2026, it will vanish into interstellar space, never to return. Based on SPHEREx observations (NASA, Feb 2026) and trajectory data.","shortDescription":"A visitor from the stars, glimpsed in passing"}}
