Vol. 63, No. 10 – October 2015 GENERAL MEETING THE PRESIDIO . OBSERVATION POST . BUILDING 211 211 Lincoln Boulevard, San Francisco 7:00 pm Doors Open . 7:30 pm Announcements . 8:00 pm Speaker SFAA’s General Meetings occur on the 3rd TUESDAY of each month (except January) October 20, 2015 NORMAN SLEEP, Ph.D. Professor of Geophysics, Stanford University OUR MOON FROM FORMATION TO ASTEROID TARGET: MESSAGE FOR LIFE ON EARTH The present EarthMoon system formed in the aftermath of the impact of a Mars sized body on our planet. The Earth was then mostly melted and the Moon accreted from a ring of vapor and liquid orbiting the Earth. Part of the impactor’s core ended up in the Moonforming disk around the Earth. Iron metal within the disk was partly oxidized by ferric iron and water. Metallic iron remained and this formed our Moon’s small core, and about 2% of the impactor’s core ended up within Earth’s mantle. It is conceivable that early asteroid bombardment on the Earth was relatively benign and that planet sterilizing impact never occurred. A dense CO2 atmosphere blanketed Earth within about 10 million years of the impact, and a solarheated greenhouse maintained 200 degrees C temperatures at the surface. Earth did not become habitable until the CO2 subducted into the mantle. Subducted oceanic crust carried carbonates into the mantle, which partially melted beneath island arcs to form alkaline CO2rich lavas. Groundwaters within these lavas are an attractive prebiotic environment. By the time of Earth’s earliest sedimentary record at about 3.8 billion years ago, the surface was clement, the ocean was near its current pH about 8, and the CO2 pressure in the air was comparable to the modern value. -
Science Fiction and Astronomy
Sci Fi Science Fiction and Astronomy Many science fiction books include subjects of astronomical interest. Here is a list of some that have been recommended to me or I’ve read. I expect that most are not in the University library but many are available in Kindle and other e-formats. At the top of my list is a URL to a much longer list by Andrew Fraknoi of the Astronomical Society of the Pacific. Each title in his list has a very brief summary indicating the kind of story it is. Andrew Fraknoi’s list (http://www.astrosociety.org/education/resources/scifi.html). Gregory Benford is a plasma physicist who has been rated by some as one of the finest observes and interpreters of science in modern fiction. Note: Timescape [Vista, ISBN 0575600500] In the Ocean of Night [Vista, ISBN 0575600357] Across the Sea of Suns [Vista, ISBN 0575600551] Great Sky River [Gallancy, ISBN 0575058315] Eater and over 2 dozen more available as e-books. Stephen Baxter Titan [Voyager, 1997, ISBN 0002254247] has been strongly recommended by New Scientist as a tense, near future, thriller you shouldn’t miss. David Brin has a PhD in astrophysics with which he brings real understanding of the Universe to his stories. The Crystal Spheres won an award. Fred Hoyle is probably the most famous astronomer to have written science fiction. The Back Cloud [Macmillan, ISBN 0333556011] is his classic, followed by A for Andromeda. Try also October the First is too late. Larry Niven’s stories include plenty of ideas inspired by modern astronomy. -
Gruber Foundation Formed at Yale Yale Joins Sloan Digital Sky Survey
Yale University Astronomy Department Newsletter Vol. 3 Fall 2011 No. 1 Yale joins Sloan Digital Sky Survey III Yale is now a fully participating member of the Sloan Digital Sky Survey III (SDSS-III) Collaboration. Although Yale was not a member during the first two phases of SDSS, the suc- cess of SDSS and the excitement of Yale astronomers about the projects and data of SDSS-III led Yale to join now. Based on citations in refereed articles and meeting abstracts, SDSS has been rated as the telescope project with the biggest sci- entific impact in history, beating out even the Hubble Space Telescope and the Keck Telescopes (c.f. Madrid, Juan P. and Macchetto, Duccio 2009arXiv0901.4552M). The previous incarnations of SDSS have imaged 13,000 square degrees, corresponding to about a third of the en- tire sky. SDSS-III is taking spectra of interesting objects that were found in these images, through a program of four sur- veys that cover three scientific themes. The Baryon Oscil- lation Spectroscopic Survey (BOSS) studies dark energy and the geometry of space. (SEE SDSS-III, p. 4) SDSS-III Data Release 8 image from January 2011 Gruber Foundation formed at Yale with prizes and fellowships in astronomy and cosmology In May of 2011, Patricia and Peter Gruber officially formed the Gruber Founda- tion at Yale University, dedicated to the advancement of science, support of young scientists, global justice, and women’s rights. The Gruber Foundation at Yale will succeed The Peter and Patricia Gruber Foundation, originally estab- lished in 1993, and carry on its philanthropic mission, including its prestigious annual science prizes. -

Astro2020 Science White Paper The radio search for technosignatures in the decade 2020–2030 Background photo: central region of the Galaxy by Yuri Beletsky, Carnegie Las Campanas Observatory Thematic Area: Planetary Systems Principal Author: Name: Jean-Luc Margot Institution: University of California, Los Angeles Email: [email protected] Phone: 310.206.8345 Co-authors: Steve Croft (University of California, Berkeley), T. Joseph W. Lazio (Jet Propulsion Laboratory), Jill Tarter (SETI Institute), Eric J. Korpela (University of California, Berkeley) March 11, 2019 1 Scientific context Are we alone in the universe? This question is one of the most profound scientific questions of our time. All life on Earth is related to a common ancestor, and the discovery of other forms of life will revolutionize our understanding of living systems. On a more philosophical level, it will transform our perception of humanity’s place in the cosmos. Observations with the NASA Kepler telescope have shown that there are billions of habitable worlds in our Galaxy [e.g., Borucki, 2016]. The profusion of planets, coupled with the abundance of life’s building blocks in the universe, suggests that life itself may be abundant. Currently, the two primary strategies for the search for life in the universe are (1) searching for biosignatures in the Solar System or around nearby stars and (2) searching for technosignatures emitted from sources in the Galaxy and beyond [e.g., National Academies of Sciences, Engineer- ing, and Medicine, 2018]. Given our present knowledge of astrobiology, there is no compelling reason to believe that one strategy is more likely to succeed than the other. -

Session 13 Learning from SF Väätänen
Worldcon 75 Academic Track Session 13: Learning from SF Saturday 10:00-11:30 Room 209 Chair: Päivi Väätänen Abstract 1: Nick Falkner (University of Adelaide, Australia): Design Fiction for Education: Driving Reinterpretation of Educational Challenges in the Present through the Construction of Working Futures in Speculative Fiction [email protected] Design fiction, a term coined by Julian Bleecker of Near Future Laboratory and popularised by Bruce Sterling, is "the deliberate use of diegetic prototypes to suspend disbelief about change." To identify areas of change, we must be able to correctly perceive those elements that require change and, after Shklovsky, we must fight habitualisation and defamiliarise elements that we would otherwise overlook. The representation of education is an important part of world building and story telling, yet many examples of education are habitualised stereotype: bored students, 19th century classroom or recitative teaching machine, all combining to provide a backdrop that is glanced over. There are examples in fiction of innovative educational practices that mirror the best 21st century pedagogical practice but these are not commonplace. While few people will pick up and read papers on pedagogy, speculative fiction can provide elements for readers that will influence the community to accept the new directions in education that are often challenged by parents, students, and teachers as not being “real education”. What we often call “real education” is merely the comfortable habitual framework of tradition and educational researchers are well aware that tradition is not necessarily a guide to the best educational practices. Computer scientists and engineers are increasingly required to consider defamiliarisation as a tool for constructing new and innovative devices and software (after Genevieve Bell et al’s “Making by Making Strange”, ACM Transactions on Computer- Human Interaction, 2005). -

This book focuses on science learning outside of the classroom. It consists of a collection of articles written by people who are involved with sevaral types of informal science education. The value of informal science education extends beyond the mere acquisition of knowledge. Attitudes toward science can be greatly influenced by science experiences outside of the classroom. The intent of this book is to highlight some of the many out-of-school opportunities which exist including zoos, museums, television, magazines and books, and a variety of creative programs and projects. The 19 articles in this volume are organized into four major sections entitled: (1) "Strategies"; (2) "The Media"; (3) "Museums and Zoos"; and (4) "Projects, Coop2titions, and Family Activities." A bibliography of 32 references on these topies is included. -

The Mutable Galaxies How Galaxies Enrich with Heavy Elements
GENERAL I ARTICLE The Mutable Galaxies How Galaxies Enrich with Heavy Elements Biman Nath Biman Nath is an Soon after the discovery of the expansion of the astrophysicist at the universe, astronomers hoped to determine the Raman Research parameters of the universe by comparing dis Institute, Bangalore. tant galaxies with nearby ones. Observing dis tant galaxies, however, meant observing them as they were long ago. A crucial assumption in Keywords these studies was that galaxies hardly change, in Galaxies, evolution of stars, the time scale of the expansion of the universe. production of elements. Beatrice Tinsley was one of the first astronomers to point out that galaxies do change. Here we discuss a simplified model of galactic evolution, and show that the comparison of its prediction with observations uncovers clues to how galaxies evolve with time. A cursory look at the starry sky at night is likely to make us think that stars, galaxies and the universe are immutable and changeless. Stars and galaxies do how ever change with time. The beginning of the last century was marked by the discovery of the expansion of the uni verse and also the development of our knowledge of the evolution of stars. Yet, the overall evolution of galaxies, as a result of stellar evolution, was considered too messy, and perhaps even negligible. The study of stars told us that stars shine as a result of thermonuclear reactions inside their cores. These Beatrice Tinsley reactions synthesize heavy elements like carbon, oxy was one of the first gen, nitrogen and so forth, beginning with hydrogen astronomers to and helium (which were created in the first few minutes point out that of the birth of the universe). -
Natural Wormholes As Gravitational Lenses
Natural Wormholes as Gravitational Lenses John G. Cramer(1)∗, Robert L. Forward(2)†, Michael S. Morris(3)‡, Matt Visser(4)§, Gregory Benford(5)∗∗, and Geoffrey A. Landis(6)†† (1) Department of Physics FM-15, University of Washington, Seattle WA 98195 (2) Forward Unlimited, P. O.

A wormhole mouth embedded in high mass density might accrete mass, giving the other mouth a net negative mass of unusual gravitational properties. The lensing of such a gravitationally negative anomalous compact halo object (GNACHO) will enhance background stars with a time profile that is observable and qualitatively different from that recently observed for massive compact halo objects (MACHOs) of positive mass. We recommend that MACHO search data be analyzed for GNACHOs. I. INTRODUCTION: WORMHOLES AND NEGATIVE MASS The work of Morris and Thorne [1,2] has led to a great deal of interest in the formation and properties of three- dimensional wormholes (topological connections between separated regions of space-time) that are solutions of the Einstein’s equations of general relativity. Subsequently Visser [3] suggested a wormhole configuration, a flat-space wormhole that is framed by “struts” of an exotic material, a variant of the cosmic string solutions of Einstein’s equations [4,5]. -
POV's Discussion Guide
POV Community Engagement & Education DISCUSSION GUIDE The City Dark A Film by Ian Cheney www.pbs.org/pov LETTER FROM THE FILMMAKER When I set out to make a film about light pollution, I knew nothing about bird migration or melatonin; I just knew I missed seeing the stars. I spent a lot of my childhood in rural Maine, where I fell in love with the night sky. From an early age, I sought to capture it on film. I experimented with long nighttime exposures using Dad’s old indestructible Pentax K1000, a simple cable-release and an unforgivable amount of Kodak Gold film. I was lucky to get one decent shot per roll. But under count - less Maine summer night skies, I succeeded in becoming something of an amateur as - tronomer, eventually attending teen astronomy camp and building my own telescope out of an old cardboard construction tube. Years later, in 2008, working as a documentary filmmaker under New York’s neon skies, I stumbled upon a curious statistic: For the first time in history, more than half of the world’s population was now living in urban areas. As a species, we’d gradually moved from countryside to city. What struck a chord was the parallel with my own life, my own progression from dark, starry skies to the brilliant, hazy skyline of America’s largest city. There was no denying I’d gained a lot since coming to New York—but what had I lost? And what might we all be losing? Some three years later, I’d talked to astronomers, biologists, ecologists, wildlife veteri - narians, criminologists, lighting designers and Boy Scouts about the myriad ways that ar - tificial light affects our world. -
