Claims of alien "hotspots" have prompted calls for the Department of Defence to monitor Irish skies for UFOs.
Astronomer Eamonn Ansbro, who has researched extraterrestrial activity for three decades, said the Government needs to take the issue seriously.
He said UFO sightings are "more prevalent" in West Cork, south Kerry, Lough Key in Co Roscommon and the north west adding: "Dublin is also quite active."
