Solar Eclipse
SOLAR ECLIPSE A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partially obscuring Earth's view of the Sun. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun, causing the sun to look like an annulus (ring), blocking most of the Sun's light. An annular eclipse appears as a partial eclipse over a region thousands of kilometers wide The solar eclipse of January 15, 2010 was an annular eclipse of the Sun with a magnitude of 0.9190. It was the longest annular solar eclipse of the millennium, [1] and the longest until December 23, 3043, with a maximum length of 11 mins and 7.8 seconds. (The solar eclipse of January 4, 1992, was longer, at 11 minutes, 41 seconds, occurring in the middle of the Pacific Ocean.)[2] The eclipse was visible as only a partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as an annular eclipse within a narrow stretch of 300 km (190 mi) width across Central Africa, Maldives, South Kerala (India), South Tamil Nadu (India), Sri Lanka and parts of Bangladesh, Burma and China. The eclipse started in the Central African Republic, traversed Cameroon, DR Congo and Uganda, passed through Nairobi, Kenya, and passed over the Indian Ocean, where it reached its greatest visibility. It then entered Maldives, where it was the longest on land with 10.8 viewable minutes. The annular eclipse at Malé, the capital city of Maldives, started at 12:20:20 and ended at 12:30:06 Maldives local time (UTC+5). -

In addition, the elliptical orbit of the Moon often takes it far enough away from Earth that its apparent size is not large enough to block the Sun entirely. -

The Moon for a Twopence: Street Telescopes in Nineteenth-Century Paris and the Epistemology of Popular Stargazing David Aubin* 1 March 2017 Abstract: In this article, I explore the epistemology of popular stargazing as it emerged in the nineteenth century. I want to chart the way in which the spectacle of the sky, a powerful metaphor of the Enlightenment, became an object of mass consumption in nineteenth-century Paris. Turning astronomy into a spectacle for wide audiences, I want to argue, went hand-in-hand with the emergence renewed forms of popular observations. To this end, I focus on the telescopes that were set up in public places (boulevards, bridges, and squares). -

33 Days: August 21, 2017 There Goes the Sun: The North American Total Solar Eclipse 2017 Randall L. Milstein, Ph.D. Oregon State University Oregon NASA Space Grant Consortium Photo: M. Druckmüller A total solar eclipse is like nothing else you will ever witness in your life; and arguably the most spectacular of natural phenomena. We have records of people witnessing eclipses for over 5,300 years. “I will make the Sun go down at noon, and darken the Earth in broad daylight.” 762 BCE Assyrian Eclipse The Book of Amos 8:9 sciencesource.com 3F8576 Stars visible during totality. Moon Sun The Eclipse of November 30, 3,340 BCE May be the earliest known recorded solar eclipse. Loughcrew Cairn Megalithic Monument Ireland Battle of the Eclipse: May 28, 585 BCE Arguably the oldest precisely dated historical event, the Eclipse of Thales ended the Battle of Halys: the Medes and Lydians interpreted it as a bad omen and declared a truce. The Norse explained eclipses as sky wolves, or wargs, Sköll and Hati who chase down and eat both the Sun (Sol) and Moon (Mani). Guerber, 1909 On “average” a total eclipse of the Sun occurs in a location once every 400 years. During the 5th, 6th, and 7th centuries CE twenty-eight major solar eclipses all crossed South America. Central and South America China Australia The Navajo people regard the cosmic order of the Universe to be about balance. A solar eclipse is just part of Nature's law. You pause and acknowledge that eclipse time is special, and you reflect on the cosmic order. -

Terrestrial Atmosphere, Water and Astrobiology
EPJ Web of Conferences 9, 241–265 (2010) DOI: 10.1051/epjconf/201009020 c Owned by the authors, published by EDP Sciences, 2010 Terrestrial atmosphere, water and astrobiology A. Brack1,a and M. Coradini2 1Centre de Biophysique Moleculaire,´ CNRS, Rue Charles Sadron, 45071 Orleans´ Cedex 2, France 2ESA, 8-10 rue Mario Nikis, 75015 Paris, France Abstract. Primitive life, defined as a chemical system capable to transfer its molecu- lar information via self-replication and also capable to evolve, originated about 4 billion years ago from the processing of organic molecules by liquid water. Terrestrial atmosphere played a key role in the process by allowing the permanent presence of liquid water and by participating in the production of carbon-based molecules. Water molecules exhibit specific properties mainly due to a dense network of hydrogen bonds. The carbon-based molecules were either home made in the atmosphere and/or in submarine hydrothermal systems or delivered by meteorites and micrometeorites. The search for possible places beyond the earth where the trilogy atmosphere/water/life could exist is the main objec- tive of astrobiology. Within the Solar System, exploration missions are dedicated to Mars, Europa, Titan and the icy bodies. The discovery of several hundreds of extrasolar planets opens the quest to the whole Milky Way. 1 Introduction Defining life is a difficult task and the intriguing and long lasting question “What is life” has not yet received a commonly accepted answer, even for what could define a minimal life, the simplest possi- ble form of life. Perhaps the most general working definition is that adopted by the NASA Exobiology Programme: “Life is a self-sustained chemical system capable of undergoing Darwinian evolution”. -
