“No one knows why they do it. Yet each fall, thousands of starlings dance in the twilight above Gretna, Scotland. The birds gather in magical shape-shifting flocks called murmurations, having migrated in the millions from Russia and Scandinavia to escape winter’s bite. Scientists aren’t sure how they do it, either. Even complex algorithmic models haven’t yet explained the starlings’ acrobatics, which rely on the tiny bird’s quicksilver reaction time of under 100 milliseconds to avoid aerial collisions—and predators—in the giant flock.”

Following a Moon Shadow
Image courtesy PHL/UPR AreciboSeen from one of Japan’s MTSAT meteorological satellites, the shadow of the moon darkens part of the North Pacific during the annular solar eclipse last Sunday and Monday. Despite the diminutive shadow shown, the moon is actually a little bigger than a quarter the size of Earth.
An annular eclipse happens when the moon lines up between Earth and the sun, and when the dark moon’s apparent diameter is smaller than the visible disk of the sun, leaving a ring—or annulus—of fiery light around the edges.
