Twenty-three researchers give insightful snapshots of current progress in a wide variety of topics of astrophysical interest, including the nature of asteroid surfaces, interstellar gas, stars and star formation, hot gas in galaxies, and quasar variability. The reviews are at a level accessible to graduate students working in astronomy and will be useful summaries of many important research areas.

A unique, wide-ranging examination of asteroid exploration and our future in space Human travel into space is an enormously expensive and unforgiving endeavor. So why go? In this accessible and authoritative book, astrophysicist Martin Elvis argues that the answer is asteroid exploration, for the strong motives of love, fear, and greed. Elvis’s personal motivation is one of scientific love—asteroid investigations may teach us about the composition of the solar system and the origins of life. A more compelling reason may be fear—of a dinosaur killer–sized asteroid hitting our planet. Finally, Elvis maintains, we should consider greed: asteroids likely hold vast riches, such as large platinum deposits, and mining them could provide both a new industry and a funding source for bolder space exploration. Elvis explains how each motive can be satisfied, and how they help one another. From the origins of life, to “space billiards,” and space sports, Elvis looks at how asteroids may be used in the not-so-distant future.

State-of-the-art review of the growing field of astrometry, for researchers and graduate students.
