"Harvard Astronomers Uncover Mysterious Galactic Wave's Encounter with Earth"
A new study published in Nature reveals that the Radcliffe Wave, a wave-shaped chain of stars and gas in our galactic neighborhood, is oscillating like a wave and may have passed over Earth 13 million years ago, potentially exposing our planet to a series of exploding stars. The wave's motion was detected using data from the Gaia project, and researchers speculate that it may have left unique isotopes on Earth. This discovery suggests that galaxies may be more dynamic than previously thought, and the cause of the wave's oscillation remains a mystery.
