Stromatolites and Earth--sun--moon Dynamics

Vanyo, J.P. and Awramik, S.M., 1985. Stromatolites and Earth--Sun--Moon dynamics. Precambrian Res., 29 : 121--142. Inclination of stromatolite columns, caused by nonvertical direction of averaged incident solar radiation, provides a signal for deducing astronomical and geophysical data at time of stromatolite formation. A sample of Anabaria juvensis (Bitter Springs Formation, central Australia)...

The Wives of the Sun and Moon

In much Native American mythology, marriage is conceptualized as a monthly honeymoon interrupted at each dark moon by menstruation. Woman’s monthly alternation between marital sex and menstrual seclusion is coded as an alternation between her rival partners, Sun and Moon. Against this background, a Plains Indian myth attempts to come to terms with a novel problem. With the introduction of patri...

Moon and Sun shadowing effect in the MACRO detector

Using data collected by the MACRO experiment from 1989 to the end of its operations in 2000, we have studied in the underground muon flux the shadowing effects due to both the Moon and the Sun. We have observed the shadow cast by the Moon at its apparent position with a significance of 6.5 σ. The Moon shadowing effect has been used to verify the pointing capability of the detector and to determ...

Moon and Sun Shadowing Observed by the MACRO Detector

Using over 40 million muons collected since 1989 by the MACRO detector we have searched for a depletion of muons coming from the direction of the Moon due to primary cosmic rays striking the Moon. We observe this Moon shadow in the expected position with a statistical significance of more than 5 standard deviations. We have analyzed the same data for an analogous Sun shadow, and have found a si...
