It wasn’t that long ago that a science teacher would have told students that there was no evidence of planets around other star systems. Even more recently, they might have …. That’s No Moon… That’s an Exoplanet!
Even more recently, they might have said that while we’ve seen evidence of extra-solar planets, we would never be able to see them directly. [Jason Wang] has several videos that use images taken over years to visualize the orbit of several large exoplanets. According to [Jason]: We unfortunately do not have the luxury of watching these planets every night and record them.
These planets move slowly, with orbital periods at least decades long, and predictably following Kepler’s laws. We can use a technique called motion interpolation to reconstruct what the image should look like using images taken before and after the date we are interested in. Motion interpolation is a technique commonly found in video editing and in modern TVs.
You have to be a patient photographer, apparently.
