Meteorites and the Origin of the Solar System
Meteorites and the origin of the solar system STEPHEN G. BRUSH University of Maryland, College Park, MD 20742, USA (e-mail: [email protected]) Abstract: During the past two centuries, theories of the origin of the solar system have been strongly influenced by observations and theories about meteorites. I review this history up to about 1985. During the 19th century the hypothesis that planets formed by accretion of small solid particles ('the meteoritic hypothesis') competed with the alternative 'nebular hypothesis' of Laplace, based on condensation from a hot gas. At the beginning of the 20th century Chamberlin and Moulton revived the meteoritic hypothesis as the 'planetesimal hypothesis' and joined it to the assumption that the solar system evolved from the encounter of the Sun with a passing star. Later, the encounter hypothesis was rejected and the planetesimal hypothesis was incorporated into new versions of the nebular hypothesis. In the 1950s, meteorites provided essential data for the establishment by Patterson and others of the pre- sently accepted 4500 Ma age of the Earth and the solar system. Analysis of the Allende meteorite, which fell in 1969, inspired the 'supernova trigger' theory of the origin of the solar system, and furnished useful constraints on theories of planetary formation developed by Urey, Ringwood, Anders and others. Many of these theories assumed condensation from a homogeneous hot gas, an assumption that was challenged by astrophysical calculations. The meteoritic-planetesimal theory of planet formation was developed in Russia by Schmidt and later by Safronov. Wetherill, in the United States, established it as the preferred theory for formation of terrestrial planets. -

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. -

FOREWORD Dorota Glowacka
FOREWORD Dorota Glowacka Try to look. Just try and see. —Charlotte Delbo, None of Us Will Return Charlotte Delbo penned her memoir None of Us Will Return to commemorate 230 women with whom she had been trans- ported from Drancy to Auschwitz-Birkenau on 24 January 1943. As one of only forty-nine members of the convoy who had “returned,” most of them French political prisoners, Delbo made a commitment to preserve the memory of her martyred comrades. With the images of tortured and dying women in- delibly seared in her mind, her narrative is punctuated with the refrain, “Try to look. Just try and see” (Essayez de regarder. Essayez pour voir).1 Delbo’s compassionate desire to see trans- forms her descriptions of horror and humiliation into a work of mourning and into an injunction that those who come after bear witness to what happened to her friends. Nowhere has similar commitment to an ethics of testimo- nial gaze been expressed with more lucidity, eloquence, and passion than in On the Death of Jews. Straddling the boundary between historical inquiry and personal refl ection, this extraor- dinary text unfolds as a series of encounters with eponymic Holocaust photographs. Although only a small number of pho- tographs are reproduced here, Fresco provides evocative de- scriptions of many well-known images: synagogues and Torah scrolls burning on the night of Kristallnacht; deportations to the ghettos and the camps; and, fi nally, mass executions in the killing fi elds of Eastern Europe. The unique set of photographs included in On the Death of Jews shows groups of women and children from Liepaja (Liepa ¯ja), shortly before they were killed On the Death of Jews Photographs and History Nadine Fresco https://www.berghahnbooks.com/title/FrescoOn viii FOREWORD in December 1941 in the dunes of Shkede (Šk,e¯de) on the Baltic Sea. -

Big Questions in Astrophysics – the Next Decades a Symposium to Celebrate the Knut and Alice Wallenberg Foundation’S 100-Year Anniversary
BIG QUESTIONS IN ASTROPHYSICS – THE NEXT DECADES A SYMPOSIUM TO CELEBRATE THE KNUT AND ALICE WALLENBERG FOUNDATION’S 100-YEAR ANNIVERSARY April 4, 2017, Grand Auditorium, Lux, Helgonavägen 3, Lund BIG QUESTIONS IN ASTROPHYSICS – THE NEXT DECADES 1 KNUT AND ALICE WALLENBERG FOUNDATION 100 YEARS IN SUPPORT OF EXCELLENT SWEDISH RESEARCH AND EDUCATION The Knut and Alice Wallenberg Foundation primarily grants funding in the natural sciences, technology and medicine, in the form of grants for basic research of the highest international standard. During the Foundation’s 100 years, SEK 24 billion has been awarded in grants for excellent Swedish research and education. Recent annual grants of SEK 1.7 billion make the Foundation one of the largest private funders of scientific research in Europe. Over their lifetimes, Knut and Alice Wallenberg built up a sizable fortune, and, even before the establishment of the Foundation, they financed various construction and public development projects. They wanted to organize their support through the establishment of the Foundation. The endowment consisted mainly of shares in Stockholms Enskilda Bank and Investor worth SEK 20 million, SEK 593 million in today’s currency value. Even though the Foundation has granted SEK 24 billion, the assets have, after 100 years and successful capital management, grown to SEK 90 billion. Knut and Alice Wallenberg were determined to promote scientific research and education beneficial to Sweden, things that contributed to Swedish progress in research and education. In the beginning, the Foundation mainly financed buildings to house research and education. Gradually the support shifted to financing of advanced equipment needed for research. -

Now it turns out that the Hubble Space Telescope had captured an image of one of them 10 years ago, but astronomers failed to spot it. This raises hope that more planets lie buried in Hubble's vast archive. In 1998, Hubble studied the star HR 8799 in the infrared, as part of a search for planets around young and relatively nearby stars. -

Water on the Moon, I. Historical Overview Arlin Crotts (Columbia University)
Water on The Moon, I. Historical Overview Arlin Crotts (Columbia University) By mid-19th century, astronomers strongly suspected that the Moon was largely dry and airless, based on the absence of any observable weather. [1] In 1892, William H. Pickering made a series of careful occultation measurements that allowed him to conclude that the lunar surface’s atmospheric pressure was less than 1/4000th of Earth’s. [2] Any number of strange ideas arose to contradict this, including Danish astronomer/mathematician Peter Andreas Hansen’s hypothesis, that the Moon’s center of mass is offset by its center of figure by 59 kilometers, meaning that one or two scale-heights of atmosphere could hide on the far side of the Moon, where it might support water oceans and life. [3] Hans Hörbiger’s 1894 Welteislehre (“World Ice”) theory, that the Moon and much of the cosmos is composed of water ice, became the favored cosmology of leaders of Third Reich Germany. [4] Respectable scientists realized that significant amounts of water on the Moon’s surface would rapidly sublime into the vacuum. [1] “The absence of any bodies of water on the moon is placed beyond doubt, both by actual telescopic examination and by inference from absence of clouds. There are no streams, lakes or seas. An eminent astronomer has remarked that the heat of the surface exposed to the sun would occasion a transfer of any water the moon might contain to its dark side, and that there may be frosts in this part, and perhaps running water near the margin of the illuminated portion.
