Book Description
In 1931, the cluster of craters at Henbury Cattle Station south of Alice Springs in Central Australia was one of the first places on Earth where a group of impact structures could definitely be linked to the fall of iron meteorites. It was also the first place where radial rays and loops of ejected rock material, comparable to those seen around craters on the Moon, were observed. As such it was one of the primary observation sites associated with the science of meteoritics in its infancy. In this work the authors present previously unpublished documents covering early research at the Henbury site, provide an extended data set on the distribution of meteoritic material at Henbury craters, and compare recent discoveries on the mechanics of hypervelocity impacts with evidence collected over 80 years of research at the Henbury meteorite craters. In their conclusion, the authors suggest a new hypothesis for the fragmentation and incident direction of the crater-forming bolide, on the basis of a more complete set of data compared with previous models.

Book Description
Filled with data about the Earth, Moon, the planets, the stars, our Galaxy, and the myriad galaxies in deep space, this invaluable resource reveals the latest scientific discoveries about black holes, quasars, and the origins of the Universe. It includes maps supported by detailed tables of the names, positions, magnitudes, and spectra of the main stars in each constellation along with key data on galaxies, nebulae, and clusters. MNASSA wrote, "This book fills a niche with detailed astronomical data and concise explanations, all at an accessible level it is an excellent resource, and probably will be the first book I shall reach for.

Book Description
This volume of the EMU Notes in Mineralogy is one of the outcomes of a school in planetary mineralogy that was held in Glasgow, Scotland, in 2014. The school was inspired by the recent advances in our understanding of the nature and evolution of our Solar System that have come from the missions to study and sample asteroids and comets, and the very successful Mars orbiters and landers. At the same time our horizons have expanded greatly with the discovery of extrasolar protoplanetary disks, planets and planetary systems by space telescopes. The continued success of such telescopic and robotic exploration requires a supply of highly skilled people and so one of the goals of the Glasgow school was to help build a community of early-career planetary scientists and space engineers.

Book Description
The Moon is the most viewed object in the sky, the Sun being too bright to look at directly and the planets too far away. The Greeks deduced everything that could be learned about the Moon using only the naked eye, including that it has no light of its own but reflects that of the Sun. They understood the cause of eclipses and used the Earth's shadow on the Moon to conclude that our planet is a sphere and to calculate the size of both the Moon and the Earth. The invention of the telescope some two millennia later offered the opportunity for much greater understanding, but the early observers became sidetracked onto a dead end: First, they fooled themselves into believing that they saw evidence of life on the Moon, even the works of a civilization. Second, they became convinced that the craters of the Moon were volcanoes like those we have on the Earth. These wrong-headed beliefs took centuries to dispel. The origin of the Moon itself has proven an even more difficult question, but scientists have now closed in on the answer. They find that our placid and seemingly unchanging Moon was born in colossal violence as a planet the size of Mars crashed into the primordial Earth and flung off a blob that solidified to become our heavenly companion. Unlocking the Moon's Secrets follows these developments to show how science evolves, complete with misunderstandings, contentious arguments, difficult to relinquish assumptions, and shifting views as new facts come to light. Thanks to the work of generations of determined scientists, we understand our Moon, at last.

Book Description
"This volume contains a sizable suite of contributions dealing with regional impact records (Australia, Sweden), impact craters and impactites, early Archean impacts and geophysical characteristics of impact structures, shock metamorphic investigations, post-impact hydrothermalism, and structural geology and morphometry of impact structures - on Earth and Mars"--

Book Description
A complete and updated catalogue of impact craters and structures in South America from 2014 is presented here. Approximately eighty proven, suspected and disproven structures have been identified by several sources in this continent. All the impact sites of this large continent have been exhaustively reviewed: the proved ones, the possible ones and some very doubtful. Many sites remain without a clear geological "in situ" confirmation and some of them could be even rejected. Argentina and Brazil are leading the list containing almost everything detected. In Bolivia, Chile, Colombia, Guyana, Paraguay, Perú, Uruguay and Venezuela only a few were observed. Only Ecuador is waiting for new discoveries. So far, the largest well stated impact site is still the Araguainha structure in Brazil with its 40 kilometers in diameter. However, two possible impact structures are larger than Araguainha: Malvinas, (with 250 kilometers in diameter) and Vichada in Colombia, (50 kilometers). This study also reports the existence of some Tertiary-Quaternary glassy impactite layers: the "escorias" and "tierras cocidas" of the pampas in Argentina.
