Scientists have discovered the first robust evidence of a black hole and neutron star orbiting in an oval path before merging, rather than the perfect circular orbits previously assumed. This groundbreaking observation challenges long-standing theories about how these cosmic pairs form and evolve in the universe.
Black hole-neutron star mergers are among the most violent events in the cosmos, producing gravitational waves detectable on Earth. These collisions were thought to occur after the objects spiraled inward in nearly circular orbits, but the new evidence suggests a more complex orbital dynamics at play.
