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)...
متن کاملCan 3D Visualization Assist in Young Children's Understanding of Sun-Earth-Moon System?
This research-in-progress investigates how the usage of technology, specifically three dimensional (3D) stereoscopic vision, might support astronomy learning in primary grades. 3D stereoscopic vision might be an effective means to observe the relationships among space objects through simulations. In order to explore this presumption, this pilot study examines how 3D stereoscopic vision might en...
متن کاملThe Sun-earth Space Information System
Nowadays the object of Space Information System (SIS) is limited to the earth surface, and the large-scale sun-earth space does not been considered. In this paper, the research object of SIS is been extended, namely the object is been studied from the earth surface to the sun-earth space, and the concept of “Sun-earth Space Information System” is been proposed. It is the very important content ...
متن کاملResonances in the Early Evolution of the Earth-moon System
Most scenarios for the formation of the Moon place the Moon near Earth in low-eccentricity orbit in the equatorial plane of Earth. We examine the dynamical evolution of the Earth-Moon system from such initial conÐgurations. We Ðnd that during the early evolution of the system, strong orbital resonances are encountered. Passage through these resonances can excite large lunar orbital eccentricity...
متن کاملAccretion of Terrestrial Planets and the Earth/moon System
Introduction: The leading paradigm for the origin of the terrestrial planets is the planetesimal hypothesis, which proposes that mutual collisions between objects in the protoplanetary disk resulted in the accretional growth of increasingly massive bodies, ending with the formation of planets in the 0.5 to 1.5AU region. Two decades of analytical modeling and numerical simulation have revealed t...
