Grey aliens, also referred to as Zeta Reticulans, Roswell Greys, or simply Greys, are purported extraterrestrial beings. They are frequently reported in alleged alien abductions and other close encounters. Greys are typically described as hairless humanoids with grey skin, small bodies, disproportionately large heads, and large almond-shaped eyes without sclerae. The 1961 Barney and Betty Hill abduction claim was key to the dissemination of the concept of Grey aliens and their subsequent popularity in modern culture. Precursor figures have been described in science fiction and similar descriptions appeared in later accounts of the 1947 Roswell UFO incident and early accounts of the 1948 Aztec UFO hoax. The Grey alien is cited as an archetypal image of an intelligent, non-human being and extraterrestrial life in general, as well as an iconic trope of popular culture in the age of space exploration.
