Astronomy Although the existence of exomoons—moons orbiting extrasolar planets—is probable, direct observational evidence has been elusive. Previous observations made using NASA's Kepler space telescope suggested that Kepler-1625b, a Jupiter-sized planet orbiting the solar-mass yellow star Kepler-1625, may be orbited by an exomoon.

A new look at photometry of the Moon
Icarus, 2010Abstract We use ROLO photometry (Kieffer, H.H., Stone, T.C. [2005]. Astron. J. 129, 2887–2901) to characterize the before and after full Moon radiance variation for a typical highlands site and a typical mare site. Focusing on the phase angle range 45° α I / F at small incidence angles (high Sun) is used as an estimate of I / F for zero ...

The most sophisticated simulations yet of the Moon's birth show that it could have been created from an impact of a large body with a fully formed, rather than half-formed, Earth.

“The Old Moon in the Arms of the New”
Contributions of the Society for Research on Meteorites, 1945ABSTRACTIt is suggested that variations in the lunar earthshine may be due at times, in part at least, to intense meteoritic activity on the Moon. In view of this possibility, it may be worth‐while to record the intensity of the earthshine, especially when rich showers of meteors are observed to be in progress here on the Earth.

New Institute Shoots for the Moon
Science, 2008ELECTION 2008The home of the new NASA Lunar Science Institute lacks air conditioning, a conference room, and a working water fountain. But lunar scientists hope to refurbish the shabby surroundings as part of a larger renovation that will set the agenda for a new generation of scientific exploration.
