How to Observe the Moon: 1 How to Observe the Moon: 1. Look up - The simplest way to observe the Moon is simply to look up. The Moon is the brightest object in our night sky, the second brightest in our daytime sky, and can be seen from all around the world. With the naked eye, you can see dark gray seas of cooled lava called mare. 2. Peer through a telescope or binoculars - With some magnification help, you will be able to identify details on the Moon. The line between night and day on the Moon (called the terminator) is ideal for seeing lunar craters and mountains since very long shadows heighten the contrast of the features. 3. Photograph the Moon - Our Lunar Reconnaissance Orbiter (LRO) has taken more than 20 million images of the Moon, mapping it in stunning detail. You can take your own photos from Earth, too! 4. Make and admire Moon art – People have been making moon inspired art for millennia. You can enjoy artwork of the Moon and create anything from drawings, painting, poetry, songs, and more. 5. Continue your observations throughout the year - International Observe the Moon Night is the perfect time to start a Moon journal. See how the shape of the Moon seems to change over the course of a month, and keep track of where and what time it rises and sets. Where is the Moon Tonight? On September 26th, the Moon will rise in the early evening around 5:00PM in the Southeast; however mountains, trees, buildings and other material may get in the way until about 6 PM. The moon will reach its highest position in the sky, due south, around 9:30 PM. Near middle of the night the moon will finally set at 1:30 AM in the Southwest. What Phase is the Moon Tonight? The moon will be a waxing Gibbous on September 26th. That means it will be growing in illumination, filled right to left as seen from the northern hemisphere, and more than half but not completely full. The moon will be about 74% full. Why Does the Moon Have Phases? As the moon orbits the Earth, we see its day/night cycle creating the phases of the moon. As the moon waxes, or grows, the face we see from Earth becomes illuminated by the Sun from New to Crescent, to Half, to Gibbous, to Full. After becoming Full, the moon wanes, and the amount of sunlight reaching the face of the moon we see from earth decrease and it becomes gibbous, then half, then crescent, and back to new. It takes about 29 earth days for the moon to have just one day! The 29-day cycle of the moon is known as the “MOONth” and where we get the word ‘month’ from! Activity: The Moon's phases in Oreos (adapted from https://spaceplace.nasa.gov/oreo-moon/en/) Why does the Moon look different throughout the month? The Moon has "phases." That means it looks a little different to us each night during its one-month orbit of our planet. We describe how the Moon looks with terms such as "Full Moon," "First Quarter," and "New Moon" (which we can't really see, because the side that is lit faces away from us). The Moon has no light of its own. Moonlight is sunlight bouncing off the Moon's surface. As the Moon orbits Earth, the Sun lights up whatever side of the Moon is facing it. To the Sun, it's always a full Moon! If you were looking down upon Earth and its Moon from way out in space over the North Pole, you would see a Moon that looked like the figure on the left. But we see the Moon from the center of its orbit. So we see different portions of the lit side of the Moon, as shown by the figure on the bottom of the page! Modeling the Moon Phases Using the placemat below as guide, open up some Oreo cookies and scrape off the creme filling to make the four major phases of the Moon (shown on the right). These Oreo "Moons" show how the Moon looks from Earth during these phases. What phase of the moon do we see tonight?

The front page of this newspaper was extremely helpful to our project because we used it to see how this event impacted the whole world not just America. Beloff, Nora. “The Space Race: Experts Not Keen on Getting a Man on the Moon.” Age [Melbourne] 24 April 1962. 2. Print. This was an incredibly important article to use in out presentation so that we could see different opinions. This article talked about how some people did not want to go to the moon; we didn’t find many articles like this one. In most everything we have read it talks about the advantages of going to the moon. This is why this article was so unique and important. Canadian Press. “Half-billion Watch the Moon Spectacular.” Gazette [Montreal] 21 July 1969. 4. Print. This source gave us a clear idea about how big this event really was, not only was it a big deal in America, but everywhere else in the world. This article told how Russia and China didn’t have TV’s so they had to find other ways to hear about this event like listening to the radio.

It’s not very big - just a box a metre wide with folded solar panels attached - and six strong men could lift it. It weighs less than 370 kilograms, compared with thousands of kilos for Ariane’s usual customers’satellites. So it should pose no problems as an auxiliary passenger. SMART stands for Small Missions for Advanced Research in Technology. They pave the way for the novel and ambitious science projects of the future, by testing the new technologies that will be needed. But a SMART project is also required to be cheap - about one- fifth of the cost of a major science mission for ESA - which is why SMART-1 has no launcher of its own.

  • In Situ Observations of the Preexisting Auroral Arc by THEMIS All Sky Imagers and the FAST Spacecraft
    JOURNAL OF GEOPHYSICAL RESEARCH, VOL. 117, A05211, doi:10.1029/2011JA017128, 2012 In situ observations of the “preexisting auroral arc” by THEMIS all sky imagers and the FAST spacecraft Feifei Jiang,1 Robert J. Strangeway,1 Margaret G. Kivelson,1,2 James M. Weygand,1 Raymond J. Walker,1 Krishan K. Khurana,1 Yukitoshi Nishimura,3 Vassilis Angelopoulos,1 and Eric Donovan4 Received 6 September 2011; revised 25 January 2012; accepted 6 March 2012; published 5 May 2012. [1] Auroral substorms were first described more than 40 years ago, and their atmospheric and magnetospheric signatures have been investigated extensively. However, because magnetic mapping from the ionosphere to the equator is uncertain especially during active times, the magnetospheric source regions of the substorm-associated features in the upper atmosphere remain poorly understood. In optical images, auroral substorms always involve brightening followed by poleward expansion of a discrete auroral arc. The arc that brightens is usually the most equatorward of several auroral arcs that remain quiescent for 30 min or more before the break-up commences. In order to identify the magnetospheric region that is magnetically conjugate to this preexisting arc, we combine auroral images from ground-based imagers, magnetic field and particle data from low-altitude spacecraft, and maps of field-aligned currents based on ground magnetometer arrays. We surveyed data from the THEMIS all sky imager (ASI) array and the FAST spacecraft from 2007 to April 2009 and obtained 5 events in which the low altitude FAST spacecraft crossed magnetic flux tubes linked to a preexisting auroral arc imaged by THEMIS ASI prior to substorm onset.

    CHAPTER EXTRACTS WONDER STRUCK BY MARGARET FEINBERG AWAKEN TO THE NEARNESS OF GOD In Wonderstruck, Margaret invites you to unearth the extraordinary moments in every day life, recognize the presence of God in the midst of your routine, and discover peace in knowing you’re wildly loved. Winsome yet compelling, whimsical yet profound, the stories from Wonderstruck will inspire you to fall in love anew with God. Wonderstruck consists of eleven chapters full of practical steps, challenging questions, intimate stories, and Biblical insights culminating in a 30 Days of Wonder Challenge. This book and Bible study are for anyone who wants to live astounded by God and walk in the fullness of all He offers. 1 TRANSFORMATIONAL COMMUNITY COMMUNITY TRANSFORMATIONAL “[Feinberg] succeeds in keeping the reader engaged, entertained, and edified . [She] raises questions that linger in the mind after the book is closed.” PUBLISHERS WEEKLY Margaret Feinberg is a modern-day David. With eyes on the heavens, His Word in hand, and all her heart turned towards His, she tells the wonders of His love in ways you’ve never known. Who in the world doesn’t need joy like this? ANN VOSKAMP Author of One Thousand Gifts “Feinberg turns exegesis into an art, delivering findings that invite the audience to touch, taste, smell, and see God’s handiwork throughout the Scriptures and in their own lives.” ED STETZER President, LifeWay Research We dangerously underestimate the power of wonder . Margaret recenters wonder at the heart of our relationship with God, with seismic results. This book shook my soul awake and made it impossible for me to continue following a God of my own design.
