Phases of Venus and Galileo
Galileo and the phases of Venus I) Periods of Venus 1) Synodical period and phases The synodic period1 of Venus is 584 days The superior2 conjunction occured on 11 may 1610. Calculate the date of the quadrature, of the inferior conjunction and of the next superior conjunction, supposing the motions of the Earth and Venus are circular and uniform. In fact the next superior conjunction occured on 11 december 1611 and inferior conjunction on 26 february 1611. 2) Sidereal period The sidereal period of the Earth is 365.25 days. Calculate the sidereal period of Venus. II) Phases on Venus in geo and heliocentric models 1) Phases in differents models 1) Determine the phases of Venus in geocentric models, where the Earth is at the center of the universe and planets orbit around (Venus “above” or “below” the sun) * Pseudo-Aristoteles model : Earth (center)-Moon-Sun-Mercury-Venus-Mars-Jupiter-Saturne * Ptolemeo’s model : Earth (center)-Moon-Mercury-Venus-Sun-Mars-Jupiter-Saturne 2) Determine the phases of Venus in the heliocentric model, where planets orbit around the sun. Copernican system : Sun (center)-Mercury-Venus-Earth-Mars-Jupiter-Saturne 2) Observations of Galileo Galileo (1564-1642) observed Venus in 1610-1611 with a telescope. Read the letters of Galileo. May we conclude that the Copernican model is the only one available ? When did Galileo begins to observe Venus? Give the approximate dates of the quadrature and of the inferior conjunction? What are the approximate dates of the 5 observations of Galileo supposing the figure from the Essayer, was drawn in 1610-1611 1 The synodic period is the time that it takes for the object to reappear at the same point in the sky, relative to the Sun, as observed from Earth; i.e. -

Astronomical Calculations for The
Astronomical Calculations for The Real Star of Bethlehem While the spectacular astronomical signs in the 18 months from May 3 B.C. to December 2 B.C. would have caused wonderful interpretations by astrologers on behalf of Augustus and the Roman Empire, the Magi decided to go to Jerusalem with gifts to a newborn Jewish king. The Magi focused on Judaea and not Rome at this crucial time in history. Let us look at some of the astrological and biblical factors that may have brought the Magi to Jerusalem and then to Bethlehem. Since the New Testament says the Magi saw the “star” rising in the east, it would most naturally be called a “morning star.” The Book of Revelation has Jesus saying of himself, “I am the root and offspring of David, and the bright and morning star.” 1 The apostle Peter also mentioned that Jesus was symbolically associated with “the day star.” 2 The above verses refer to celestial bodies that were well known and recognized in the 1st century and they inspired symbolic messianic interpretation by early Christians. There were several prophecies in Isaiah which generally were interpreted as referring to the Messiah. One has definite astronomical overtones to it. Isaiah said, “The Gentiles shall come to thy light, and kings to the brightness of thy rising.” 3 This prophecy could easily refer to the rising of some star. It would be particularly appropriate to a “morning” or “day” star. Luke, in his Gospel, referring to the celestial symbolism of Isaiah 60:3 which spoke of God as being “the daybreak [the rising] from on high that hath visited us, to give light to them that sit in darkness.” 4 Astronomy and the New Testament These references reveal that celestial bodies were symbolically important to the New Testament writers. -
Make up Lab: Phases of Venus Introduction Galileo Is Justifiably Famous for Many Discoveries in Both Physics and Astronomy
PHYS 1401: Descriptive Astronomy Summer 2016 Make Up Lab: Phases of Venus Introduction Galileo is justifiably famous for many discoveries in both physics and astronomy. While he was fascinated by gravity and kinematics, his most valuable discovery is arguably the phases of Venus. By carefully observing and recording the progression of Venus through phases similar to our own moon, he was able to demonstrate the impossibility of the Ptolemy’s increasingly complicated geocentric model. 4. Orient yourself: Toggle on the constellation outlines and labels. Locate one or two constellations whose shapes you know. Are the constellations of 1610 recognizable to you? Face north and locate Polaris. Comment on the location of Polaris compared to its position today. Synodic Period of Venus The synodic period of an object is a measure of its motion with respect to Earth. We are most familiar with this idea as applied to the moon: to measure its synodic period, we count the time between successive full moons (or new moons, or whichever phase you like). As Galileo discovered, we can do precisely the same thing for Venus. 5. Change the date and locate Venus: Advance your date to May 01, 1610. Keep the time set to 00:00:00. Locate Venus, and zoom in to notice its phase. Advance your day until Venus Using the Stellarium program, we can replicate his is fully illuminated (100.0%) and record the date. Use the table observations by placing ourselves in the same time and place below as a model for recording your data. as Galileo himself. 6. -
The Birth of Christ & Christmas Star- a Possible Explanation
The Birth of Christ & Christmas Star- A Possible Explanation By Rich Jacobs, M.D. Godʼs Word tells us about the “Star of Bethlehem”. This star has baffled believers and cynics alike for generations. To know what the Christmas star could have been, we must first look at what Godʼs Word has to say about it. Then, we must look to the historical and astronomical clues to gather the facts we need to come to a conclusion. And, we must forget all the wrong things we have been told about the Star and that wonderful night, if we are to come to the truth. Letʼs begin with Godʼs Word. Matthew 2:1-12 1 After Jesus was born in Bethlehem in Judea, during the time of King Herod, Magi from the east came to Jerusalem 2 and asked, "Where is the one who has been born king of the Jews? We saw his star in the east and have come to worship him." 3 When King Herod heard this he was disturbed, and all Jerusalem with him. 4 When he had called together all the people's chief priests and teachers of the law, he asked them where the Christ was to be born. 5 "In Bethlehem in Judea," they replied, "for this is what the prophet has written: 6 "'But you, Bethlehem, in the land of Judah, are by no means least among the rulers of Judah; for out of you will come a ruler who will be the shepherd of my people Israel.'" 7 Then Herod called the Magi secretly and found out from them the exact time the star had appeared. -
Star of Bethlehem: an Astronomical and Historical Perspective
THE STAR OF BETHLEHEM: AN ASTRONOMICAL AND HISTORICAL PERSPECTIVE By Susan S. Carroll The Star of Bethlehem is one of the most powerful, and enigmatic, symbols of Christianity. Second perhaps only to the Cross of the Crucifixion, the importance of its role in the story of the Nativity of the Christ child is almost on a par with the birth itself. However, the true origin of the Star of Bethlehem has baffled astronomers, historians, and theologians for the past two millennia. For the purposes of this discussion we shall consider four possibilities: That the star was a one-shot occurrence - never before seen and has not been seen since; it was placed in the sky by God to announce the birth of His Son; That the Star was added to the story of the Nativity after the fact; That the Star was a real, documentable astronomical object; That the entire New Testament is fake. If you subscribe to the first theory, then we, as astronomers, have nothing to talk about. It was a supernatural miracle that defies scientific explanation. However, many theologians insist on putting some sort of divine interpretation on Matthew s writings. By admitting that the Star was a natural phenomenon, with an actual scientific explanation, is tantamount to totally removing its heavy symbolic significance. After all, how could something so miraculous have such a mundane explanation? There is a certain amount of credence to the second theory. At the time of Jesus' birth, very few people recognized its significance. The only time the Star is mentioned at all is in the Book of Matthew. -

Christmas Ball Star of Bethlehem by Mary Ann Stephens
“Star of Bethlehem” Christmas Ball Pattern overview: Circularly-knit, ball-shaped ornament with symmetrical, stranded knitting motif repeated across all four panels. I-cord hanging loop is shown, but the common crocheted chain loop will work, too. If you’re having trouble understanding the layout of the chart, this article of mine should prove helpful. Suggested yarn: A (background): One 50g ball of Dale of Norway “Heilo” 100% Norwegian wool or “Falk” 100% superwash wool in Off-White #0018. B (motif): One 50g ball of Dale of Norway “Gullfasan” 90% viscose / 10% polyamide metallic yarn in Gold #2633. Note: Heilo and Gullfasan have been discontinued; Falk is no longer sold in North America. To get comparably sized balls (approximately 3” / 8cm) you can substitute with many other sport to DK weight yarns. GAUGE: The gauge on the ball shown is about 28 stitches per 4” / 10cm. But, in this case, the gauge is not crucial. What matters is that you’re happy with the resulting fabric and that you keep your gauge consistent across multiple balls, especially if they will be hanging together on your tree. NEEDLES: US #3 / 3.25mm, or whatever size needle you need to obtain your preferred gauge. You can use double-pointed needles (extra helpful, but not essential, for the I-cord hanging loop), one long circular needle with the magic loop method, or two circular needles. NOTIONS: Wool or polyester batting, to stuff the balls. I always love wool, and it makes a nice, firm stuffing, especially for balls that are meant to be decorative keepsakes. -

Gabriel: (looks down at Michael and his watch confused) (playfully) Uhhh.. It’s exactly the fourteenth year of Augustus… you know annus quattuordecimus, as these Romans say. Michael: No, no, no! I want it in the new time. I can’t remember! Is it B.C. or A.D? Gabriel: (excited) Oh yeah! It’s about time for the changeover! Tonight at midnight, the Lord God lights that new star over Bethlehem… then all the angels have to set their watches ahead to A.D.! Michael: Oh okay A.D. ... What’s that mean? Gabriel: ( trying to remember) I remember it means anno Domini, year of the Lord. It means Jesus Time. The whole world is going to use it! It all becomes official as soon as the Lord God takes the brakes off that new star! Michael:(stops walking) (cautiously) Hey, Gabriel, how are they coming along on that new star? Gabriel: (stop, turn, getting excited) I just flew by the Star Foundry yesterday. Mike, this is going to be a big one! Bright too! You remember how all the angels were wearing sunglasses when the Lord God started dumping the hydrogen in Andromeda? Well, This one’s bigger and brighter. It makes Halley’s comet look like a (looking for words)…...sulfur match! Michael: (walk again with Gabriel) Sulfur Match? © 2016 University Presbyterian Church Gabriel: (turn, walking) Never mind, Michael! They’re pumping the helium in now. -

NASA and Planetary Exploration
**EU5 Chap 2(263-300) 2/20/03 1:16 PM Page 263 Chapter Two NASA and Planetary Exploration by Amy Paige Snyder Prelude to NASA’s Planetary Exploration Program Four and a half billion years ago, a rotating cloud of gaseous and dusty material on the fringes of the Milky Way galaxy flattened into a disk, forming a star from the inner- most matter. Collisions among dust particles orbiting the newly-formed star, which humans call the Sun, formed kilometer-sized bodies called planetesimals which in turn aggregated to form the present-day planets.1 On the third planet from the Sun, several billions of years of evolution gave rise to a species of living beings equipped with the intel- lectual capacity to speculate about the nature of the heavens above them. Long before the era of interplanetary travel using robotic spacecraft, Greeks observing the night skies with their eyes alone noticed that five objects above failed to move with the other pinpoints of light, and thus named them planets, for “wan- derers.”2 For the next six thousand years, humans living in regions of the Mediterranean and Europe strove to make sense of the physical characteristics of the enigmatic planets.3 Building on the work of the Babylonians, Chaldeans, and Hellenistic Greeks who had developed mathematical methods to predict planetary motion, Claudius Ptolemy of Alexandria put forth a theory in the second century A.D. that the planets moved in small circles, or epicycles, around a larger circle centered on Earth.4 Only partially explaining the planets’ motions, this theory dominated until Nicolaus Copernicus of present-day Poland became dissatisfied with the inadequacies of epicycle theory in the mid-sixteenth century; a more logical explanation of the observed motions, he found, was to consider the Sun the pivot of planetary orbits.5 1.
