Recent research suggests that our solar system might be experiencing a comet shower, potentially caused by a star that passed through the Oort Cloud long ago.
The Oort Cloud is a vast region filled with icy bodies that exist at the outer edges of our solar system. A disturbance from a nearby star could have sent many comets on a collision course with the inner solar system.
This theory could help explain the increased frequency of comet sightings in recent years, as these celestial objects make their way toward the Sun.
