Wait for the Next Crossing
Three imagined telescopes illustrate a proposed test at separated observing positions.

Richard Stanton proposed synchronized telescopes, separated by tens of meters, to measure the motion of future optical disturbances. Differences in their arrival times could help distinguish nearby atmospheric effects from faster-moving objects in Earth’s orbital neighborhood or the wider solar system.
THE OBSERVATION
What we can actually see.
The 2025 journal paper reports the HD 89389 pair and a comparison with an earlier record. A subsequent conference paper discusses three paired events in different stars and proposes synchronized telescopes. The 4.4-second separation belongs to the two observed disturbances in HD 89389’s light; it is not a measured gravitational-lensing delay.
THE ILLUSTRATION
What the artwork imagines.
This is an AI-generated illustration of an array idea, not a photograph of a completed experiment. Equipment, separation and the landscape are not a surveyed plan. The artwork is not a direct astronomical observation.
FROM THE ILLUSTRATED ARTICLE
The story that inspired it.
The article follows an unusual optical record into competing explanations and a possible timing experiment. Richard Stanton proposed synchronized telescopes, separated by tens of meters, to measure the motion of future optical disturbances. Differences in their arrival times could help distinguish nearby atmospheric effects from faster-moving objects in Earth’s orbital neighborhood or the wider solar system.
