THUBAN the Star Thuban in the Constellation Draco (The Dragon) Was the North Pole Star Some 5,000 Years Ago, When the Egyptians Were Building the Pyramids
STAR OF THE WEEK: THUBAN The star Thuban in the constellation Draco (the Dragon) was the North Pole Star some 5,000 years ago, when the Egyptians were building the pyramids. Thuban is not a particularly bright star. At magnitude 3.7 and known as alpha draconis it is not even the brightest star in its constellation. What is Thuban’s connection with the pyramids of Egypt? Among the many mysteries surrounding Egypt’s pyramids are the so-called “air shafts” in the Great Pyramid of Giza. These narrow passageways were once thought to serve for ventilation as the The Great Pyramid of Giza, an enduring monument of ancient pyramids were being built. In the 1960s, though, Egypt. Egyptologists believe that it was built as a tomb for fourth dynasty Egyptian Pharaoh Khufu around 2560 BC the air shafts were recognized as being aligned with stars or areas of sky as the sky appeared for the pyramids’ builders 5,000 years ago. To this day, the purpose of all these passageways inside the Great Pyramid isn’t clear, although some might have been connected to rituals associated with the king’s ascension to the heavens. Whatever their purpose, the Great Pyramid of Giza reveals that its builders knew the starry skies intimately. They surely knew Thuban was their Pole Star, the point around which the heavens appeared to turn. Various sources claim that Thuban almost exactly pinpointed the position of the north celestial pole in the This diagram shows the so-called air shafts in the Great year 2787 B.C. -

Tomlinson left it in his will that his estate should be turned into public buildings for the city after his wife also passed. It read " He passed on November 14, 1870. His wife made a contract in 1871 by which the city would take ownership of the property and she would receive $7,000 per year until her death. Tomlinson Hall was then constructed in 1885–86. The approximate cost of the building, with running water and heating, was $137,500. On January 30, 1958, a four- alarm fire engulfed the building. Despite public dissent, the building was razed on July 8, 1958 as it could not be saved. It was not reconstructed. Sunset Terrace: With the end of prohibition in the United States, several night clubs and taverns sprang up along Indiana Avenue after 1933. The Sunset Terrace was one of the many properties within the area owned by brothers Denver and Sea Ferguson. -
Dhruva the Ancient Indian Pole Star: Fixity, Rotation and Movement
Indian Journal of History of Science, 46.1 (2011) 23-39 DHRUVA THE ANCIENT INDIAN POLE STAR: FIXITY, ROTATION AND MOVEMENT R N IYENGAR* (Received 1 February 2010; revised 24 January 2011) Ancient historical layers of Hindu astronomy are explored in this paper with the help of the Purân.as and the Vedic texts. It is found that Dhruva as described in the Brahmân.d.a and the Vis.n.u purân.a was a star located at the tail of a celestial animal figure known as the Úiúumâra or the Dolphin. This constellation, which can be easily recognized as the modern Draco, is described vividly and accurately in the ancient texts. The body parts of the animal figure are made of fourteen stars, the last four of which including Dhruva on the tail are said to never set. The Taittirîya Âran.yaka text of the Kr.s.n.a-yajurveda school which is more ancient than the above Purân.as describes this constellation by the same name and lists fourteen stars the last among them being named Abhaya, equated with Dhruva, at the tail end of the figure. The accented Vedic text Ekâgni-kân.d.a of the same school recommends observation of Dhruva the fixed Pole Star during marriages. The above Vedic texts are more ancient than the Gr.hya-sûtra literature which was the basis for indologists to deny the existence of a fixed North Star during the Vedic period. However the various Purân.ic and Vedic textual evidence studied here for the first time, leads to the conclusion that in India for the Yajurvedic people Thuban (α-Draconis) was Dhruva the Pole Star c 2800 BC. -

The Relative Sizes of the Sun and Stars 25
The relative sizes of the sun and stars 25 Stars come in many sizes, but their true appearances are impossible to see without special telescopes. The image to the left was taken by the Hubble Space telescope and resolves the red supergiant star Betelgeuse so that its surface can be just barely seen. Follow the number clues below to compare the sizes of some other familiar stars! Problem 1 - The sun's diameter if 10 times the diameter of Jupiter. If Jupiter is 11 times larger than Earth, how much larger than Earth is the Sun? Problem 2 - Capella is three times larger than Regulus, and Regulus is twice as large as Sirius. How much larger is Capella than Sirius? Problem 3 - Vega is 3/2 the size of Sirius, and Sirius is 1/12 the size of Polaris. How much larger is Polaris than Vega? Problem 4 - Nunki is 1/10 the size of Rigel, and Rigel is 1/5 the size of Deneb. How large is Nunki compared to Deneb? Problem 5 - Deneb is 1/8 the size of VY Canis Majoris, and VY Canis Majoris is 504 times the size of Regulus. How large is Deneb compared to Regulus? Problem 6 - Aldebaran is 3 times the size of Capella, and Capella is twice the size of Polaris. How large is Aldebaran compared to Polaris? Problem 7 - Antares is half the size of Mu Cephi. If Mu Cephi is 28 times as large as Rigel, and Rigel is 50 times as large as Alpha Centauri, how large is Antares compared to Alpha Centauri? Problem 8 - The Sun is 1/4 the diameter of Regulus. -

Chasing the Pole — Howard L. Cohen
Reprinted From AAC Newsletter FirstLight (2010 May/June) Chasing the Pole — Howard L. Cohen Polaris like supernal beacon burns, a pivot-gem amid our star-lit Dome ~ Charles Never Holmes (1916) ew star gazers often believe the North Star (Polaris) is brightest of all, even mistaking Venus for this best known star. More advanced star gazers soon learn dozens of Nnighttime gems appear brighter, forty-seven in fact. Polaris only shines at magnitude +2.0 and can even be difficult to see in light polluted skies. On the other hand, Sirius, brightest of all nighttime stars (at magnitude -1.4), shines twenty-five times brighter! Beginning star gazers also often believe this guidepost star faithfully defines the direction north. Although other stars staunchly circle the heavens during night’s darkness, many think this pole star remains steadfast in its position always marking a fixed point on the sky. Indeed, a popular and often used Shakespeare quote (from Julius Caesar) is in tune with this perception: “I am constant as the northern star, Of whose true-fix'd and resting quality There is no fellow in the firmament.” More advanced star gazers know better, that the “true-fix’d and resting quality”of the northern star is only an approximation. Not only does this north star slowly circle the northen heavenly pole (Fig. 1) but this famous star is also not quite constant in light, slightly varying about 0.03 magnitudes. Polaris, in fact, is the brightest appearing Cepheid variable, a type of pulsating star. Still, Polaris is a good marker of the north cardinal point. -

THE IMPORTANCE of STARS for HUMANS the STARS the Reason Why Stars Are So Important Is Because They Have Helped Humans Navigate Through Earth
THE IMPORTANCE OF STARS FOR HUMANS THE STARS The reason why stars are so important is because they have helped humans navigate through Earth . When it was dark these stars would light up the sky giving people light . In addition stars are very important because they make life on Earth. the most important is the Sun, because without that it wouldn't be life on Earth . Earth would just be a rock with ice. Stars since ancient times are discribed as forever, hope, destiny, heaven and freedom. They have also for us people great importance and we believe that falling stars make our wishes. For example: Ancient sailors used the stars to help guide them while they were at sea. Just like Phoenicians looked to the sun’s movement across the heaven to tell them their direction. THE IMPORTANCE OF SUN Life as we know would not be possible without the heat and Also the solar energy offers clean power with light of the sun. different benefits like: The infrared light of the sun give us the warmth we need to • Important for the protection of the environment live. • Prevents destruction of habitats The exposition to sunlight ultraviolet radiations also help us to • Combats climate change form vitamin-D in our bodies. This vitamin helps us to build • Social and economic benefits teeths, bones and helps the body to absorb calcium. THE POLE STAR The Pole Star, or Polaris, is directly above Earth's North Pole. A pole star is lined up whit earths axis, because of it's position over the North Pole, it's the only star that doesn't move so it’s important for the orientation. -
CONSTELLATION URSA MINOR, the LITTLE BEAR Ursa Minor
CONSTELLATION URSA MINOR, THE LITTLE BEAR Ursa Minor (Latin: "Smaller She-Bear", to contrast with Ursa Major), also known as the Little Bear, is a constellation in the northern sky. Like the Great Bear, the tail of the Little Bear may also be seen as the handle of a ladle, hence the North American name, Little Dipper. It has seven main stars with four in its bowl, like its partner the Big Dipper. It was one of the 48 constellations listed by the 2nd-century astronomer Ptolemy, and remains one of the 88 modern constellations. Ursa Minor has traditionally been important for navigation, particularly by mariners, because of Polaris (at the end of the tail) being the North Star. Alpha Ursae Minoris, better known as Polaris, is the brightest star in the constellation, is a yellow-white supergiant and the brightest Cepheid variable star in the night sky, ranging from an apparent magnitude of 1.97 to 2.00. Beta Ursae Minoris, also known as Kochab, is an aging star that has swollen and cooled to become an orange giant with an apparent magnitude of 2.08, only slightly fainter than Polaris. Gamma Ursae Minoris, magnitude 3 and Kochab have been called the "guardians of the pole star". Planets have been detected orbiting four of the stars, including Kochab. The constellation also contains an isolated neutron star—Calvera—and H1504+65, the hottest white dwarf yet discovered, with a surface temperature of 200,000 K. HISTORY AND MYTHOLOGY In the Babylonian star catalogues, Ursa Minor was known as the Wagon of Heaven, Damkianna.
