The size or energy of diverse structures or phenomena in geoscience appears to follow
power law distributions. A rigorous statistical analysis of such observations is tricky, though …

The Moon is generally depleted in volatile elements and this depletion extends to the
surface where the most abundant mineral, anorthite, features< 6 ppm H 2 O. Presumably the …

Technology has advanced to the point that it is possible to image the entire sky every night
and process the data in real time. The sky is hardly static: many interesting phenomena …

The debiased absolute-magnitude and orbit distributions as well as source regions for near-
Earth objects (NEOs) provide a fundamental frame of reference for studies of individual …

Most large (over a kilometre in diameter) near-Earth asteroids are now known, but
recognition that airbursts (or fireballs resulting from nuclear-weapon-sized detonations of …

INTRODUCTION The color and reflectance of asteroids can be used to infer their
compositions and histories. Variations in these spectrophotometric properties are driven by …

Context. Until recently, camera networks designed for monitoring fireballs worldwide were
not fully automated, implying that in case of a meteorite fall, the recovery campaign was …

Some of the global warming from anthropogenic greenhouse gases is offset by increased
reflection of solar radiation by clouds with smaller droplets that form in air polluted with …

An asteroid's history is determined in large part by its strength against collisions with other
objects,(impact strength). Laboratory experiments on centimetre-scale meteorites have been …

We model the cratering of the Moon and terrestrial planets from the present knowledge of
the orbital and size distribution of asteroids and comets in the inner Solar System, in order to …
