A rare green comet is set to be visible in the Irish skies in a once-in-a-lifetime event.
Skygazers can catch a glimpse of the comet, known as Comet C/2022 E3 or ZTF, this week and the next. It will be the brightest on February 1 and 2.
ZTF has not been visible from Earth since the Stone Age as it only orbits the sun every 50,000 years. The comet comes from the Oort cloud at the edge of the solar system.
