Rehder D. Chemistry in Space. From Interstellar Matter to the Origin of Life
Wiley. 2010. 304 p.

On 27th December 1984, a team of meteorite hunters, funded by the National Science Foundation, picked up a rock of 1.93 kg in an Antarctic area known as Alan Hills. Since it was the fi rst one to be collected in 1984, it was labeled ALH84001, AL an H ills 19 84 no. 00 1 . Soon it became evident that this meteorite originated from our neighbor planet Mars – a rock that formed 4.1 billion years ago and was blasted off the red planet ’ s crust 15 million years ago by an impacting planetesimal. After roaming about in the Solar System for most of its time, this rock entered into the irresistible force of Earth ’ s attraction, where it landed 13 thousand years ago, in Antarctica and hence in an area where it was protected, at least in part, from weathering. Structural elements detected in this Martian meteorite, considered to represent biomarkers, sparked off a controversial debate on the possibility of early microbial life on our neighbor planet about 4 billion years ago, and shipping of Martian life forms to Earth, a debate which became reignited by recent reinvestigations of the meteoritic inclusions.
Other meteorites, originating from objects in the asteroid belt between Mars and Jupiter, have brought amino acids and nucleobases to Earth, among these amino acids which are essential for terrestrial life forms. Does this hint toward an extraterrestrial origin of at least part of the building blocks necessary for terrestrial life? And if yes – how could amino acids, which are rather complex molecules, have been synthesized and survived under conditions prevailing in space?

Springer Science and Business Media, 2012, 172 pages, ISBN: 1441988211 For over ten years, the dark side of the universe has been headline news. Detailed studies of the rotation of spiral galaxies, and 'mirages' created by clusters of galaxies bending the light from very remote objects, have convinced astronomers of the presence of large quantities of dark (unseen) matter in the cosmos. The most striking fact is that they seem to compromise ab...

Cambridge University Press, 2010. - 205 pp. Most astronomers and physicists now believe that the matter content of the Universe is dominated by dark matter: hypothetical particles which interact with normal matter primarily through the force of gravity. Though invisible to current direct detection methods, dark matter can explain a variety of astronomical observations. This book describes how this theory has developed over the past 75 years, and...
