Webb Could Help Check Them. Two new studies outline how a future space observatory could find planets around pairs of dead stars, then test some candidates with infrared light. NewJinMedia · November 12, 2026 Space-science analysis A planet can give itself away without crossing in front of a star or appearing as a separate point in a telescope image. Its gravity can pull the objects it orbits into a small wobble. Astronomers already exploit that motion in starlight. Two studies highlighted by NASA on November 10 explore how a future observatory could read a related signature in gravitational waves, potentially exposing a...
