Messier Objects
Messier Objects From the Stocker Astroscience Center at Florida International University Miami Florida The Messier Project Main contributors: • Daniel Puentes • Steven Revesz • Bobby Martinez Charles Messier • Gabriel Salazar • Riya Gandhi • Dr. James Webb – Director, Stocker Astroscience center • All images reduced and combined using MIRA image processing software. (Mirametrics) What are Messier Objects? • Messier objects are a list of astronomical sources compiled by Charles Messier, an 18th and early 19th century astronomer. He created a list of distracting objects to avoid while comet hunting. This list now contains over 110 objects, many of which are the most famous astronomical bodies known. The list contains planetary nebula, star clusters, and other galaxies. - Bobby Martinez The Telescope The telescope used to take these images is an Astronomical Consultants and Equipment (ACE) 24- inch (0.61-meter) Ritchey-Chretien reflecting telescope. It has a focal ratio of F6.2 and is supported on a structure independent of the building that houses it. It is equipped with a Finger Lakes 1kx1k CCD camera cooled to -30o C at the Cassegrain focus. It is equipped with dual filter wheels, the first containing UBVRI scientific filters and the second RGBL color filters. Messier 1 Found 6,500 light years away in the constellation of Taurus, the Crab Nebula (known as M1) is a supernova remnant. The original supernova that formed the crab nebula was observed by Chinese, Japanese and Arab astronomers in 1054 AD as an incredibly bright “Guest star” which was visible for over twenty-two months. The supernova that produced the Crab Nebula is thought to have been an evolved star roughly ten times more massive than the Sun. -

How We Found About COMETS
How we found about COMETS Isaac Asimov Isaac Asimov is a master storyteller, one of the world’s greatest writers of science fiction. He is also a noted expert on the history of scientific development, with a gift for explaining the wonders of science to non- experts, both young and old. These stories are science-facts, but just as readable as science fiction.Before we found out about comets, the superstitious thought they were signs of bad times ahead. The ancient Greeks called comets “aster kometes” meaning hairy stars. Even to the modern day astronomer, these nomads of the solar system remain a puzzle. Isaac Asimov makes a difficult subject understandable and enjoyable to read. 1. The hairy stars Human beings have been watching the sky at night for many thousands of years because it is so beautiful. For one thing, there are thousands of stars scattered over the sky, some brighter than others. These stars make a pattern that is the same night after night and that slowly turns in a smooth and regular way. There is the Moon, which does not seem a mere dot of light like the stars, but a larger body. Sometimes it is a perfect circle of light but at other times it is a different shape—a half circle or a curved crescent. It moves against the stars from night to night. One midnight, it could be near a particular star, and the next midnight, quite far away from that star. There are also visible 5 star-like objects that are brighter than the stars. -

Maria Margaretha Kirch - Wikipedia Seite 1 von 2 Anlage 3 WIKIPEDIA Maria Margaretha Kirch Marua Margareföa Kirch, geborene Wmkelmann (' 25 Februar i67o in Pamtzsch bei Leipmg, t 29 Dezember 1720 in Berlin), war eine deutsche Astronomin. Inhaltsverzeichnis Leben Ehrungen Literatur Weblinks Einzelnachweise Leben Maria Margareföa Winkelmann war die jüngste von drei Töchtern des lutherischen Pa.stors Matthias Winkelmann ('+ 1682) und der Buch- und Tuchhändlerstochter Maria Töllner (t i683). Der Vater soll ihr Interesse an der Astronomie geweckt und gefördert haben. Mit i3 Jahren wurde sie durch den Tod ihrer Mutter Vollwaise und wuchs seitdem bei ihrer Schvvester Sara Elisabeth auf. Als Vormund erzog und unterwies sie der pietistische Amtsnachfolger ihres Vaters in Panitzsch, Justinus Töllner, der später ihre Schwester heiratete. Ihre zweite Schwester Anna Magdalena heiratete dessen Bruder Heinrich Tönner. Maria Margaretha trat, vermutlich als Dienstbotin, in den Haushalt des mit Justinus Töllner befreundeten Bauernastronomen Ch0stp?ph Amold im Nachbardorf Sommerfeld ein, bei dem sie sich grundlegende Kenntnisse und Erfahrungen im Tätigkeitsbereich astronomischer Beobachtungen aneignete. Dort wurde sie auch in die ersten Gmndlagen der Meteorologie eingeführt. Bei Arnold lernte sie ihren späteren Ehemann, den dreißig Jahre älteren verwitweten Astronomen und Kalendermacher Gottfried Kirch kennen, der Arnold Unterricht in Astronomie gab und mit ihm gemeinsame Beobachtungen durchführte. Im Mai 1692 heiratete sie Gottfried Kirch, den sie bei den Observationen und Berechnungen unterstützte. Beide waren radikale Pietisten und mussten im Laufe der Verfolgungen der evangelischen Reformbewegung aufgmnd der Festnahme einiger Glaubensbrüder Leipzig verlassen, worauföin sie in Gottfrieds Geburtsstadt Guben zogen. Dort gebar sie ihre Kinider Marie (i6g3 -i6g7), Christfrjed, Chris0ne und Sophie (i6g8-1699). -
Initial Characterization of Interstellar Comet 2I/Borisov
Initial characterization of interstellar comet 2I/Borisov Piotr Guzik1*, Michał Drahus1*, Krzysztof Rusek2, Wacław Waniak1, Giacomo Cannizzaro3,4, Inés Pastor-Marazuela5,6 1 Astronomical Observatory, Jagiellonian University, Kraków, Poland 2 AGH University of Science and Technology, Kraków, Poland 3 SRON, Netherlands Institute for Space Research, Utrecht, the Netherlands 4 Department of Astrophysics/IMAPP, Radboud University, Nijmegen, the Netherlands 5 Anton Pannekoek Institute for Astronomy, University of Amsterdam, Amsterdam, the Netherlands 6 ASTRON, Netherlands Institute for Radio Astronomy, Dwingeloo, the Netherlands * These authors contributed equally to this work; email: [email protected], [email protected] Interstellar comets penetrating through the Solar System had been anticipated for decades1,2. The discovery of asteroidal-looking ‘Oumuamua3,4 was thus a huge surprise and a puzzle. Furthermore, the physical properties of the ‘first scout’ turned out to be impossible to reconcile with Solar System objects4–6, challenging our view of interstellar minor bodies7,8. Here, we report the identification and early characterization of a new interstellar object, which has an evidently cometary appearance. The body was discovered by Gennady Borisov on 30 August 2019 UT and subsequently identified as hyperbolic by our data mining code in publicly available astrometric data. The initial orbital solution implies a very high hyperbolic excess speed of ~32 km s−1, consistent with ‘Oumuamua9 and theoretical predictions2,7. Images taken on 10 and 13 September 2019 UT with the William Herschel Telescope and Gemini North Telescope show an extended coma and a faint, broad tail. We measure a slightly reddish colour with a g′–r′ colour index of 0.66 ± 0.01 mag, compatible with Solar System comets. -

On the Trail of Comets
Issue 10 – March 2006 On the trail of comets The frontispiece to Hevelius’ great work on comets, the Cometographia (published in Danzig in 1668) showing rival theories about the origin and motion of comets. On the left Aristotle demonstrates his theory that comets are terrestrial exhalations that have ascended to the upper atmosphere. On the right Kepler suggests that comets move in straight lines. Seated in the middle Hevelius expounds his own theory that comets are expelled from the turbulent atmospheres of Jupiter and Saturn and move in curved paths. The history of the study of comets was discussed at the start of the recent RAS Discussion Meeting on Comets: From Antiquity to the Present Day. This meeting had been arranged to celebrate the tercentenary of the publication of Edmond Halley’s Synopsis of the Astronomy of Comets in 1705. A report appears inside.
