Ice& Stone 2020
Ice & Stone 2020 WEEK 41: OCTOBER 4-10 Presented by The Earthrise Institute # 41 Authored by Alan Hale This week in history OCTOBER 4 5 6 7 8 9 10 OCTOBER 4, 2020: The main-belt asteroid (1679) Nevanlinna will occult the 7th-magnitude star HD 224945 in Pisces. The predicted path of the occultation crosses Newfoundland, part of the Maritime Provinces of Canada, the northeastern through the south-central U.S. (including Houston, Texas), north-central Mexico (including the northern regions of Monterrey, Nuevo Leon), and the southern Pacific Ocean. OCTOBER 4 5 6 7 8 9 10 OCTOBER 7, 2008: Twenty hours after its discovery by Richard Kowalski during the course of the Mount Lemmon Survey in Arizona, the tiny asteroid 2008 TC3 enters Earth’s atmosphere above Sudan, explodes, and drops meteorite fragments – the Almahata Sitta meteorite – on the Nubian Desert. This is the first instance of an impacting asteroid being discovered in space while still inbound to an impact, and it is the subject of this week’s “Special Topics” presentation. OCTOBER 7, 2009: Astronomers using the Infrared Telescope Facility in Hawaii announce that the surface of the large main-belt asteroid (24) Themis appears to be completely covered with water ice. The significance of this discovery is discussed in a previous “Special Topics” presentation. OCTOBER 4 5 6 7 8 9 10 OCTOBER 8, 1769: Comet Messier C/1769 P1 passes through perihelion at a heliocentric distance of 0.123 AU. This was the brightest comet discovered by the 18th-Century French comet hunter Charles Messier and is a previous “Comet of the Week.” OCTOBER 4 5 6 7 8 9 10 OCTOBER 9, 1933: A brief but strong “storm” of Draconid meteors is seen over Europe. -

MBAs of such sizes are generally not access- ible to ground-based observations. Therefore, when NEAs approach the Earth (at distances which can be as small as 0.01-0.02 AU and sometimes less) they give a unique chance to study objects of such small sizes. Some of them possibly represent primordial matter, which has preserved a record of the earliest stages of the Solar System evolution, while the majority are fragments coming from catastrophic collisions that occurred in the asteroid main- belt and could provide “a look” at the interior of their much larger parent bodies. Therefore, NEAs are objects of special interest for sev- eral reasons. First, from the point of view of fundamental science, the problems raised by their origin in planet- crossing orbits, their life-time, their possible genetic relations with comets and meteorites, etc. are closely connected with the solution of the major problem of “We are now on the threshold of a new era of asteroid planetary science of the origin and evolution of the Solar studies” System. -

Statistical Survey and Analysis of Photometric and Spectroscopic Data on Neas

Raghavendra2, S.A.Ahmed1, D. Shanti Priya1 and Syeda Azeem Unnisa3 1Department of Astronomy, Osmania University, Hyderabad 2Nizam College, Osmania University, Hyderabad 3Department of Environmental Science, Osmania University, Hyderabad ABSTRACT Studies on Near Earth Asteroids (NEAs) throw light on discoveries, identification, orbit prediction and civil alert capabilities, including potential asteroid impact hazards. Due to various new observational programs, the discovery rate of NEAs has drastically increased over the last few years. In this paper we present the statistical survey and analysis of fundamental parameters (derived from Photometric and Spectroscopic observations) of a large sample of NEAs from various databases like IAU Minor Planet Center, European Asteroid Research Node (E.A.R.N.), Near Earth Objects - Dynamic Site (NEODyS- 2), M4AST and SMASSMTT portals. We also discuss the characterization of NEAs on the basis of the correlations between the parameters studied from different observations and their physical implications in understanding the nature and physical properties of these objects. Keywords: NEOs; Apollo; Amor; Aten; Observations: Photometric, Spectroscopic.

Appendix A: Scientific Notation
Appendix A: Scientific Notation Since in astronomy we often have to deal with large numbers, writing a lot of zeros is not only cumbersome, but also inefficient and difficult to count. Scientists use the system of scientific notation, where the number of zeros is short handed to a superscript. For example, 10 has one zero and is written as 101 in scientific notation. Similarly, 100 is 102, 100 is 103. So we have: 103 equals a thousand, 106 equals a million, 109 is called a billion (U.S. usage), and 1012 a trillion. Now the U.S. federal government budget is in the trillions of dollars, ordinary people really cannot grasp the magnitude of the number. In the metric system, the prefix kilo- stands for 1,000, e.g., a kilogram. For a million, the prefix mega- is used, e.g. megaton (1,000,000 or 106 ton). A billion hertz (a unit of frequency) is gigahertz, although I have not heard of the use of a giga-meter. More rarely still is the use of tera (1012). For small numbers, the practice is similar. 0.1 is 10À1, 0.01 is 10À2, and 0.001 is 10À3. The prefix of milli- refers to 10À3, e.g. as in millimeter, whereas a micro- second is 10À6 ¼ 0.000001 s. It is now trendy to talk about nano-technology, which refers to solid-state device with sizes on the scale of 10À9 m, or about 10 times the size of an atom. With this kind of shorthand convenience, one can really go overboard. -
Deep Carbon Science
From Crust to Core Carbon plays a fundamental role on Earth. It forms the chemical backbone for all essential organic molecules produced by living organ- isms. Carbon-based fuels supply most of society’s energy, and atmos- pheric carbon dioxide has a huge impact on Earth’s climate. This book provides a complete history of the emergence and development of the new interdisciplinary field of deep carbon science. It traces four cen- turies of history during which the inner workings of the dynamic Earth were discovered, and it documents the extraordinary scientific revolutions that changed our understanding of carbon on Earth for- ever: carbon’s origin in exploding stars; the discovery of the internal heat source driving the Earth’s carbon cycle; and the tectonic revolu- tion. Written with an engaging narrative style and covering the scien- tific endeavors of about 150 pioneers of deep geoscience, this is a fascinating book for students and researchers working in Earth system science and deep carbon research. is a life fellow at St. Edmund’s College, University of Cambridge.

REVIEW ARTICLE INTERNATIONAL MICROBIOLOGY (2004) 7:239-248 www.im.microbios.org Jordi Llorca Organic matter in meteorites Department of Inorganic Chemistry, University of Barcelona, Spain Summary. Some primitive meteorites are carbon-rich objects containing a vari- ety of organic molecules that constitute a valuable record of organic chemical evo- lution in the universe prior to the appearance of microorganisms. Families of com- pounds include hydrocarbons, alcohols, aldehydes, ketones, carboxylic acids, amino acids, amines, amides, heterocycles, phosphonic acids, sulfonic acids, sugar-relat- ed compounds and poorly defined high-molecular weight macromolecules. A vari- ety of environments are required in order to explain this organic inventory, includ- ing interstellar processes, gas-grain reactions operating in the solar nebula, and hydrothermal alteration of parent bodies.

Three Decades of Small-Telescope Science
Three Decades of Small-Telescope Science A Report on the 2011 Society for Astronomical Sciences 30th Annual Sym- posium on Telescope Science Robert K. Buchheim For three decades, the Society for Astronomical Sciences has supported small telescope sci- ence, encouraged amateur research, and facilitated pro-am collaboration. On May 24-26, more than one hundred participants in the 30th anniversary SAS Symposium heard presentations cov- ering a wide range of astronomical topics, reaching from the laboratory to the distant cosmos. From Planets to Galaxies Sky & Telescope Editor-in-Chief Bob Naeye opened the technical session with a review of the amateur contributions to exoplanet discovery and research through monitoring of transits and micro-lensing events. R. Jay GaBany described his participation as an astro-imager in the search for evidence of galactic mergers. His exquisite deep images taken with his 24-inch telescope displayed the di- verse patterns of star streams that can be left behind when a dwarf galaxy is disrupted and ab- sorbed by a larger galaxy. He also noted that not all faint structures are evidence of galactic mergers: the faint ”loop” structure near M-81 is actually foreground “galactic cirrus” in our own Milky Way masquerading as a faux tidal loop. Education and Outreach Several papers related to education and outreach were presented. Debra Ceravolo applied her expertise in the generation and perception of colors, to describe a new method of merging narrow-band (e.g. Hα) and broad-band (e.g. RGB) images into a natural-color image that displays enhanced detail without glaring false colors.
