For most of history, humans have been watching the night-sky (Hawkins, 1983). Historically, individuals have watched the night-sky for aesthetic appreciation and to gain insights and knowledge (Brecher & Feirtag, 1979). Despite the long history of night-sky watching among humans and the apparent importance of the behavior to large groups of contemporary individuals (i.e., amateur astronomers), this behavior has only recently become a focus of scientific study. To provide a foundation for studying night-sky watching, Kelly (2003) surveyed a small sample of college students about their attitudes towards the night-sky. The results indicated two important findings: 1) there was a general positive attitude towards night-sky watching and 2) a single underlying construct appeared to account for night-sky watching attitudes. Kelly termed this construct noctcaelador, psychological attachment to the night-sky. Kelly and Kelly (2003) found that noctcaelador appears to influence night-sky watching behaviors and some basic night-sky related life decisions. One finding of Kelly and Kelly pertinent to the present study was that individuals higher in noctcaelador are also more likely to report sacrificing sleep the night before a personally important event to watch the night-sky. It is possible, therefore, that higher noctcaelador individuals might generally attain less sleep at least partially as a result of night-sky watching behaviors. If this is the case, individuals scoring higher on a measure of noctcaelador should also tend to report less habitual sleep.
