The biological effects of asteroid and comet impacts have been
widely viewed as primarily destructive. The role of an impactor in
the K/T boundary extinctions has had a particularly important
influence on thinking concerning the role of impacts in ecological
and biological changes. th During the 10 and final workshop of the
ESF IMPACT program during March 2003, we sought to investigate the
wider aspects of the involvement of impact events in biological
processes, including the beneficial role of these events from the
prebiotic through to the ecosystem level. The ESF IMPACT programme
(1998-2003) was an interdisciplinary effort that is aimed at
understanding impact processes and their effects on the Earth
environment, including environmental, geological and biological
changes. The IMPACT programme has 15 member states and the
activities of the programme range from workshops to short courses
on topics such as impact stratigraphy, shock metamorphism, etc. The
program has also awarded mobility grants and been involved in the
development of teaching aids and numerous publications, including
this one.
Only 10% of the 150 or so known impact craters on Earth date from
the early Precambrian Era, a time period covering some 88% of the
Earth's history. Yet this Era encompasses fundamental events in the
origin and evolution of our planet from the origin of life itself
to the development of continents. The papers in this volume were
presented at a workshop sponsored by the European Science
Foundation Scientific Network on Impact cratering held in
Cambridge, UK, in December 1998. The papers outline the present
state of scientific understanding of the role impacts may have
played in the biological and geological evolution of the Early
Earth.
Ongoing advances in Solar System exploration continue to reveal its
splendour and diversity in remarkable detail. This
undergraduate-level textbook presents fascinating descriptions and
colour images of the bodies in the Solar System, the processes that
occur upon and within them, and their origins and evolution. It
highlights important concepts and techniques in boxed summaries,
while questions and exercises are embedded at appropriate points
throughout the text, with full solutions provided. Written and
edited by a team of practising planetary scientists, this third
edition has been updated to reflect our current knowledge. It is
ideal for introductory courses on the subject, and is suitable for
self-study. The text is supported by online resources, hosted at
www.cambridge.org/solarsystem3, which include selected figures from
the book, self-assessment questions and sample tutor assignments,
with outlines of suggested answers.
How did life on Earth begin? How common is it elsewhere in the
Universe? Written and edited by planetary scientists and
astrobiologists, this undergraduate-level textbook provides an
introduction to the origin and nature of life, the habitable
environments in our solar system and the techniques most
successfully used for discovery and characterisation of exoplanets.
This third edition has been thoroughly revised to embrace the
latest developments in this field. Updated topics include the
origins of water on Earth, the exploration of habitable
environments on Mars, Europa and Enceladus, and the burgeoning
discoveries in exoplanetary systems. Ideal for introductory courses
on the subject, the textbook is also well-suited for self-study. It
highlights important concepts and techniques in boxed summaries,
with questions and exercises throughout the text, with full
solutions provided. Online resources, hosted at
www.cambridge.org/features/planets, include selected figures from
the book, self-assessment questions and sample tutor assignments.
