A concise companion and update to Vicki Oransky Wittenstein’s Planet Hunter (2010).
An enticing overview of tools, techniques, and discoveries in what the author rightly characterizes “a red-hot field in astronomy.”
Alas; it is perhaps too red-hot. Not only is Kenney’s count of accepted and potential exoplanets (as of May 2016) well out of date already, but her claim that “Wolf-1061” (sic: that’s actually the name of the star and its system) is the nearest Earthlike planet in the habitable “Goldilocks Zone” has been trumped by the recent discovery of a closer candidate orbiting Proxima Centauri. Still, along with describing in nontechnical terms each tool in the researcher’s kit—from space- and ground-based telescopes of various types to instruments that detect subtle stellar wobbles, spectrum changes, microlensing, and other telling signs—the author fills in the historical background of exoplanet research and profiles some of its weirder findings. She also casts side glances at extremophile life on Earth and other, at least tangentially related, topics. The small format gives the assortment of photos, artists’ renditions, diagrams, and generic star fields a cramped look, but readers curious about how researchers could possibly detect such dinky, distant objects as planets belonging to other star systems will come away satisfied and intrigued.

Will the world end in a bang or a whimper? Unless pre-empted by human-induced disaster or one of many scientifically possible catastrophic scenarios, life on Earth will end a billion years from now in a sizzle.
Predicting the end of the world is an old story, argues the author, presenting evidence in brief surveys of eschatologies from the world's major religions and mythologies of ancient civilizations. Miller also notes how end-of-world scenarios have captured humanity's imagination in their frequent appearances in science-fiction novels and motion pictures. (Disappointingly, the reasons for this ongoing fascination are not explored.) A chapter about imminent predictions for 2012 explains the Mayan prophecy and a theory about a phantom planet called Nibiru crashing into Earth. Another chapter examines pseudoscientific end-of-world theories such as planetary alignment and pole shifts. The primary focus is on scientifically plausible scenarios: self-destruction through nuclear war or continued environmental exploitation; humanity wiped out by a pandemic; an asteroid or comet strike destroying Earth.
Attractively designed and handsomely illustrated, this informative text introduces teens to many intriguing angles on a high-interest topic that should inspire many to further explore the subject. (chronology, glossary, bibliography, further reading, index) (Nonfiction. 12-16)Pub Date: Oct. 1, 2011

A chilling look at a timely topic.
The rapid melting of Arctic ice has opened a new frontier for international competition or cooperation.
The book opens with a dramatic scene, as three men in a submersible search for a hole in the ice above the North Pole location on the ocean floor where they’ve just planted a Russian flag. McPherson goes on to describe the changes in polar ice cover that are encouraging exploration and allowing access to previously inaccessible energy resources. Subsequent chapters describe new, shorter ocean passages, the jockeying for territory as nearby nations lay claim and others look for ways to get involved, and the likely difficulties of development. Native peoples, whose livelihoods and cultures are inextricably connected to this harsh environment, have to make difficult choices, and the melting of the ice sheet over Greenland offers new opportunities as well as potential for disaster. McPherson’s clear explanations and balanced approach encourage reflection; there are no easy answers. Given that the burning of fossil fuels contributes to global warming, should the newly accessible oil and gas be extracted and added to the world’s supply? Does the North Pole belong to one or another nearby nation or to the world? Is it even possible to develop this area without spoiling it? Maps, photographs and a thoughtful design add to the package.
A chilling look at a timely topic. (source notes, glossary, bibliographies, index) (Nonfiction. 12-16)Pub Date: Oct. 1, 2014
