Black smokers, seeing ancient fossils in 3D and future of space travel

Welcome! “Alien Life” tracks the latest discoveries and thoughts in the various elements of the famous Drake Equation. You may notice that this and future entries are shorter than usual; career, family and book deal commitments have forced me to cut back some of my projects. Now, here’s today’s news:
g Abodes - Researchers are preparing for a deep-drilling project in Iceland where they will study the processes in deep, hot rocks below the terrestrial surface. Through the study, they also hope to learn more about “black smoker” hydrothermal vents in the ocean, which are known to support some of Earth's most unique lifeforms. See article.
g Life - Digital wizardry has allowed scientists to see the insides of a 53-million-year-old fossilized spider in 3-D. See article.
g Cosmicus - Book alert: What future possibilities for space travel are the most likely to succeed? What are the greatest challenges and advantages of space travel for humankind? What are the potential moral and ethical implications of our space explorations? “Space, the Final Frontier?” imaginatively illustrates the possibilities that the exploration and subsequent exploitation of space opens up for humankind. Authors Giancarlo Genta and Michael Rycroft delve into the factors that encourage space travel and speculate on the future of human expansion into space. See article.
