    Astronomy Reports, Vol. 45, No. 11, 2001, pp. 841–853. Translated from Astronomicheski˘ı Zhurnal, Vol. 78, No. 11, 2001, pp. 963–976. Original Russian Text Copyright c 2001 by Chernin, Kravtsova, Zasov, Arkhipova. Galaxies with Rows A. D. Chernin, A. S. Kravtsova, A. V. Zasov, and V. P. Arkhipova Sternberg Astronomical Institute, Universitetskii˘ pr. 13, Moscow, 119899 Russia Received March 16, 2001 Abstract—The results of a search for galaxies with straight structural elements, usually spiral-arm rows (“rows” in the terminology of Vorontsov-Vel’yaminov), are reported. The list of galaxies that possess (or probably possess) such rows includes about 200 objects, of which about 70% are brighter than 14m.On the whole, galaxies with rows make up 6–8% of all spiral galaxies with well-developed spiral patterns. Most galaxies with rows are gas-rich Sbc–Scd spirals. The fraction of interacting galaxies among them is appreciably higher than among galaxies without rows. Earlier conclusions that, as a rule, the lengths of rows are similar to their galactocentric distances and that the angles between adjacent rows are concentrated near 120◦ are confirmed. It is concluded that the rows must be transient hydrodynamic structures that develop in normal galaxies. c 2001 MAIK “Nauka/Interperiodica”. 1.

    Astronomy (Part I) Stars and Solar Systems SDH 2017 OVERVIEW: Always fascinating, always perplexing, and truly overwhelming, the night sky offers endless discoveries to those wanting to learn and explore. Students will discover the evening sky by gazing through our telescope and learn more about the systems that organize our solar system and beyond! OBJECTIVES: Students will be able to: Identify the characteristics of stars in the sky. Summarize the size and scope of Earth in the solar system and the universe. Describe the relationship between our planet and the solar system. VOCABULARY: Stars Planets General Lesson Plan Earth’s Moon Milky Way Galaxy Planet Astronomy Satellite Star Earth Cycle Astrology Moon Sun Gravity Lunar Cycle Solar Energy Orbit Solar System NEXT GENERATION SCIENCE STANDARDS: Solar energy reaches the Earth through radiation, mostly in the form of visible light. (6.4.b) The sun is a star that appears larger and brighter than other stars because it is closer. Stars range greatly in their distance from Earth. (5-ESS1-1 and ESS1.A) The orbits of earth around the sun and of the moon around Earth, together with the rotation of Earth about an axis between its North and South poles, cause observable patterns. (5-ESS1-2 and Ess1.B) Materials: Binoculars/Celestrons or Star Gazers Flashlight Procedures: 1. Introduction: Astronomy vs. Astrology? A. Have students form a circle. Then have them turn around to stare up at the stars while remaining silent. Have them observe the night sky and discuss with them what they saw. Is it different compared to what they may see back home.
