Identify the logo 9. 7 X is among the rarest of all predictable astronomical phenomena and occurs in a pattern that generally repeats every 243 years, with pairs of its occurrences eight years apart separated by long gaps of 121.5 years and 105.5 years. Its most recent occurrence was on June 5&6, 2012 and was the last of the 21st century. Prior to that it took place on June 8, 2004. The original scientific interest in observing X was that it could be used to determine the distance from the Earth to the Sun, and from this the size of the Solar System, by employing the parallax method and Keplers third law. The observation of X also led to the conclusion that there was an atmosphere on a planet named after the Roman Goddess of love and beauty. Give me X. 10. 8 __X____, during his time as an honours program undergraduate, worked in the laboratory of the geneticist H. J. Muller and wrote a thesis on the origins of life with physical chemist H. C. Urey. He used the summer months of his graduate studies to work with planetary scientist Gerard Kuiper (thesis advisor), physicist George Gamow, and chemist Melvin Calvin. He was an astronomer, astrophysicist, cosmologist, author, science populariser and science communicator in astronomy and natural sciences. He pioneered exobiology and promoted the Search for ExtraTerrestrial Intelligence (SETI). One of his famous quotes is: "The idea that God is an oversized white male with a flowing beard who sits in the sky and tallies the fall of every sparrow is ludicrous. But if by God one means the set of physical laws that govern the universe, then clearly there is such a God. This God is emotionally unsatisfying it does not make much sense to pray to the law of gravity" His saga has been carved indelibly in the history of astronomy and astrophysics. Who? 11. 9 If Horsehead - Orion, Eagle - Serpens, Cats eye - Draco; Crab 12. 10* 1. Alnitak is approximately 736 light years away from Earth and, taking into consideration ultraviolet radiation, which the human eye cannot see, it is 100,000 times more luminous than the Sun. 2. Alnilam is is approximately 1340 light years away from Earth and shines with magnitude 1.70. Considering ultraviolet light it is 375,000 times more luminous than the Sun. 3. Mintaka is 915 light years away and shines with magnitude 2.21. It is 900,000 times more luminous than the Sun. It is a double star. Both stars orbit around each other every 5.73 days. What are they collecting known as? 13. 11 Rocks that rain, spend energy in vain air is our hero, that protects you again moon is the traitor, hides them so well oh leo, oh perseus just why did they fellThis self-made poem depicts a phenomenoneasily observable during fixed certain periods.Identify 14. 12 Hindus always present detailed complex accounts of historic events. Each Yuga has its own saptarshis who govern dhruv-loka (dhruv - pole star, saptarshi - 7 stars of Ursa Major). Abhijeet was once a mighty king who even dared to challenge gods. Contesting against him Krittika (Pleides) went to forest to have him slipped and thus ultimately dethroning and defeating him. This also enabled Saptarshis to ascend dhruv to its position which Abhijeet was occupying during his conquest. This event actually signifies shifting of pole star position which happened during 12000BC. The story further states Abhijeet prayed to gods and gods forgave him thus allowing to take the position back in next yuga. This also matches with the fact that star corresponding to Abhijeet will replace Pole star as the north star in around 13,127 AD. Arguably next most important star in sky after sun, 5th brightest star of night sky; Well lyres have already started playing, who could it be? 15. 13* V838 Monocerotis (V838 Mon) is a red variable star in the constellation Monoceros about 20,000 light years from the Sun, and possibly one of the largest known stars for a short period following the outburst. The previously unknown star was observed in early 2002 experiencing a major outburst. Originally believed to be a typical nova eruption, it was then realized to be something completely different. Recently some of its images taken by the Hubble Space Telescope went viral due to the similarity in its appearance to X, a popular free and open source software which is used in conjunction with a system of interlinked hypertext documents which was the brainchild of Sir Tim Berners-Lee. What? 16. 14 It is not known exactly what causes the distinctivecolour of this unique feature. Theories supported bylaboratory experiments suppose that the color maybe caused by complex organic molecules, redphosphorus, or yet another sulphur compound. It variesgreatly in hue, sometimes to pale salmon, or evenwhite. The central region is slightly warmer than thesurroundings, which is the firstevidence that the color is affected by environmentalfactors. What am I talking about? 17. 15 The astronomer Patrick Moore points out thatSchiaparelli (18351910) "had found that his NodusGordis and Olympic Snow were almost the only featuresto be seen" during dust storms. The Mariner 9 spacecraftarrived in orbit around Mars in 1971 during a global dust-storm. The first objects to become visible as the dustbegan to settle, demonstrated that the altitude of thesefeatures greatly exceeded that of any mountain found onEarth, as astronomers expected. Observations of theplanet from Mariner 9 confirmed the existence of thisfeature which had been known to astronomers since thelate 19th century. What? 18. 16 In an anonymous footnote to his 1766 translation of Charles Bonnets Contemplation de la Nature, theastronomer Johann Daniel Titius noted an apparentpattern in the layout of the planets. In his footnoteTitius declared, "But should the Lord Architect haveleft that space empty? Not at all." This was a firstreference to what? 19. 17 The two moons of mars are 20. 18.
