Variations in the sky brightness during a lunar eclipse
A total lunar eclipse is conjectured to have influence on the physical conditions of an environmental area, particularly on the brightness of the sky. The phenomenon might also be relevant on weather parameters change on Earth, such as temperature, humidity and pressure, though a straightforward correlation is not easy to establish. This work mainly aims at measuring the brightness of the sky a...
متن کاملLunar eclipse observations reveal anomalous thermal performance of Apollo reflectors
Laser ranging measurements during the total lunar eclipse on 2010 December 21 verify previously suspected thermal lensing in the retroreflectors left on the lunar surface by the Apollo astronauts. Signal levels during the eclipse far exceeded those historically seen at full moon, and varied over an order of magnitude as the eclipse progressed. These variations can be understood via a straightfo...
متن کاملRecent Advances in Lunar Seismology
Introduction: The most detailed knowledge that we have on the interior structure so far concerning planetary bodies besides the Earth is the Moon. The Apollo seismic data have provided us with a unique opportunity to elucidate the internal structure of the Moon. The primary data set employed here are the Apollo seismic data which were obtained in the period from 1969 to 1972 when the US Apollo ...
متن کاملLunar eclipse theory revisited Scattered sunlight in both the quiescent and the volcanically perturbed atmosphere
The residual brightness of the shadowed Moon during a lunar eclipse is attributed to unscattered sunlight rays refracted in the Earth’s atmosphere. The classical theory of lunar eclipses is built on the premise that the sunlight scattered by the gases and particles in the atmosphere contributes negligibly to the brightness of the eclipsed Moon. The current work revisits the lunar eclipse theory...
متن کاملMeteor Storm Evidence against the Recent Formation of Lunar Crater
It has been suggested that the formation of 22 km diameter lunar crater Giordano Bruno was witnessed in June 1178 AD [1]. To date, this hypothesis has not been well tested. Such an impact on the Earth would be “civilization threatening.” Previous studies have shown that the formation of Giordano Bruno would lead to the arrival of 10 million tonnes of ejecta in the Earth’s atmosphere in the foll...
