Although the term ‘UFO’ (unidentified flying object) in the true sense of the word merely refers to an unexplained observation in the sky, today it is inextricably associated with ideas of extraterrestrial spaceships.

Regardless of this, the UFO topic has been (re-)legitimized both politically and scientifically in recent years.
Against the backdrop of these developments, the thematic focus “Extraterrestrials and UFOs” at IGPP is dedicated to three key questions:
