12-Year Time-Lapse Shows Four Planets Orbiting a Distant Star

Original: A 12-year sequence of telescope images of a star and four planets orbiting

Astronomers have assembled 12 years of telescope images into a sequence showing a star and four planets orbiting it, making visible the motion of exoplanets around their host over more than a decade. The composite is being widely shared, with many noting how rare it is to see multiple exoplanets move in direct images rather than being inferred from indirect measurements.

Why now: Directly watching multiple exoplanets orbit over 12 years is rare and visually striking, drawing broad attention to advances in exoplanet imaging.
