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. -
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. -

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). -

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. -

Women in Astronomy: an Introductory Resource Guide
Women in Astronomy: An Introductory Resource Guide by Andrew Fraknoi (Fromm Institute, University of San Francisco) [April 2019] © copyright 2019 by Andrew Fraknoi. All rights reserved. For permission to use, or to suggest additional materials, please contact the author at e-mail: fraknoi {at} fhda {dot} edu This guide to non-technical English-language materials is not meant to be a comprehensive or scholarly introduction to the complex topic of the role of women in astronomy. It is simply a resource for educators and students who wish to begin exploring the challenges and triumphs of women of the past and present. It’s also an opportunity to get to know the lives and work of some of the key women who have overcome prejudice and exclusion to make significant contributions to our field. We only include a representative selection of living women astronomers about whom non-technical material at the level of beginning astronomy students is easily available. Lack of inclusion in this introductory list is not meant to suggest any less importance. We also don’t include Wikipedia articles, although those are sometimes a good place for students to begin. Suggestions for additional non-technical listings are most welcome.

May/June 2008 Issue 140 A Publication for the members of the American Astronomical President’s Column 5 J. Craig Wheeler, [email protected] Astrozone and K12 Educator Two interesting years go by very rapidly. This is my last newsletter article as President. Reception My thanks to all of you who have commented positively on them for your support and to those of you who did not feel so moved on your discretion. 6-9 My term ends with a bang rather than a whimper with the sudden resignation of Alan Stern and Scenes from the the return to the NASA Science Mission Directorate of old hand Ed Weiler. Reading between the lines, my take on this transition is that Alan was dedicated to doing more with a fixed Austin Meeting budget. An important boundary condition is that he could not allow cost growth in missions. His approach to this was one of tough love. He intended to first say “no.” Any mission with 17 a threat of overrun had to find its own way of solving that problem by downscoping or delay. If, in especially pressing circumstances, the damage could not be contained in the mission, Honored Alan intended to keep it in the division. No bleeding of planetary problems into astrophysics, Elsewhere nor vice versa. I think what happened is that Alan foresaw overruns coming down the pike for which various pressures beyond his control would not allow him to exercise this tough love. It was thus a matter of principle for him to resign. He did so, by his own statement, with 19 respect for the NASA Administrator and for the team he had assembled. -

[Your Letterhead Here]
FOR IMMEDIATE RELEASE Dr. Bruce Elmegreen, of IBM Research, to receive the 2021 Bruce Gold Medal The Astronomical Society of the Pacific (ASP) is proud to announce the 2021 recipient of its most prestigious award, the Catherine Wolfe Bruce Gold Medal honoring Dr. Bruce Elmegreen, in recognition of his pioneering work on dynamical processes of star formation. SAN FRANCISCO, California – August 24, 2021 After four decades of innovative research, Dr. Elmegreen has fundamentally changed our understanding of star formation. He studied widespread hierarchical structure in young stellar regions, discovered that star formation is rapid following turbulent compression and gravitational collapse of these regions, explained the formation of stellar clusters, and discovered the largest scales for these processes in galaxies beyond our own, spanning a wide range of cosmic time. Elmegreen was born in Milwaukee, Wisconsin, and received a B.S. in Physics and Astronomy from the University of Wisconsin, Madison. He earned his PhD at Princeton University under the guidance of Lyman Spitzer, Jr. (Bruce Medal awardee, 1973), studying the ionization of the local interstellar medium. His interests turned to interstellar dynamics as a Junior Fellow at Harvard University, where, together with a colleague, he proposed that ionization from one generation of stars can compress residual gas and form another generation. He followed that with observations of interstellar filaments as further evidence for triggered collapse and proposed the same process on the scale of spiral arms. General observations and acceptance of these ideas would take several decades. After six years on the faculty of Columbia University in the City of New York, Elmegreen moved to IBM Research in 1984 where he began studies of galactic spirals, making the first digitized color images of galaxies and examining their symmetries to find spiral modes. -
President's Column
March/AprilAAS 2011, Issue 157 - TheNewsletter Online Publication for the members of the American Astronomical Society CONTENTS President's Column Debra Meloy Elmegreen, [email protected] 3 From the Seattle was the scene for a grand, fast-paced and entertaining Executive Officer 217th meeting, filled with exciting new results presented by our wonderful AAS members. We set a record for the West Coast and achieved the largest AAS meeting ever, outside of DC, with over 5 2900 participants, including over 600 junior members. As usual, Council Actions the hard work of AAS Executive Officer Kevin Marvel and his staff resulted in a smooth meeting experience for us. We were captivated by plenary sessions covering the gamut from exoplanets to the 6 early universe. The inaugural Lancelot Berkeley prizewinners, Bill Borucki and David Koch, gave Boston Meeting inspiring talks about the exciting Kepler results, and the first Kavli Prize lecturer, Dr. Carolyn Porco, 22-26 May described the Cassini mission. Our Warner prizewinner Scott Ransom expounded on exotic pulsars, while Pierce prizewinner Tommaso Treu discussed the growth of black holes and galaxy evolution, 8 and Cannon prizewinner Anna Frebel explored the oldest known stars. Rossi prizewinners Felix Committee News Aharonian, Werner Hoffmann, and Heinz Voelk described the successful H.E.S.S collaboration, while Heineman awardees Michael Turner and Rocky Kolb entertained us with a lively cosmology and particle astrophysics lecture. 10 With these prizewinners and so many other exciting talks still fresh in mind, I exhort you to nominate Seattle Meeting your colleagues for the next round of AAS prizes.
