A distant exoplanet mysteriously vanished from sight. Astronomers just discovered why
AI-summarised brief · reviewed before publication
Astronomers have explained the disappearance of exoplanet TOI‑2535 b, a hot Jupiter 1,000 light‑years away, after seven years of observation with NASA’s TESS telescope. The planet’s orbit, once regular, began arriving up to six hours early or late, and in March 2026 its transits vanished. Analysis shows an unseen companion is gravitationally tugging on TOI‑2535 b, causing its orbit to wobble and tilt out of alignment with its star. The interaction may reveal a rare, slow inward migration pathway for hot Jupiters.
