CAROLINA SKIES APRIL 2017 To use your star chart, hold it over your head. To avoid ruining your night vision with a bright flashlight, use a red light. Or put a red balloon or brown paper bag over your flashlight for a muted glow. Align north on the chart with north in the night sky by finding Polaris, ~1.5 hours after sunset the North Star. Begin by locating the Big Dipper.

Constellation Creation
Constellation Creation Constellations are fun to identify in the night sky, have helped humans navigate and chart the seasons for thousands of years, are the stuff of great legends and myths, but what can these patterns really tell us about stars?

Constellations with Prominent Stars That Can Be Found Near the Meridian at 10 Pm on January 15
ONSTELLATIONS C Altitude Ruler The rotation of the Earth on its axis causes the stars to rise and set each evening. In addition, the orbit of the Earth around the Sun places different regions of the sky in our Horizon night-time view. The PLANISPHERE is an extremely useful tool for finding stars and 10 constellation in the sky, depicting not only what is currently in the sky but it also allows the 20 prediction of the rising and setting times of various celestial objects. 30 THE LAYOUT OF THE PLANISPHERE 40 50 The outer circumference of the dark blue circular disk (which is called the star wheel) you’ll notice that the wheel is divided into the 12 months, and that each month is divided into 60 individual dates. The star wheel rotates about the brass fastener, which represents the 70 North Celestial Pole. The frame of the planisphere has times along the outer edge. 80 Holding the planisphere on the southern corner you'll see "midnight" at the top. Moving Zenith counterclockwise, notice how the hours progress, through 1 AM, 2 AM, and so on through "noon" at the bottom. The hours then proceed through the afternoon and evening (1 PM, 2 PM, etc.) back toward midnight. Once you have the wheel set properly for the correct time and day, the displayed part represents what you see if you stand with the star and planet locator held directly over your head with the brass fastener toward the north. (Notice that the compass directions are also written on the corners of the frame.) Of course, you don't have to actually stand that way to make use of the Star and Planet Locator--this is just a description to help you understand what is displayed.

Creating a Constellation
CLASSROOM ACTIVITY Creating a Constellation General Information Level: elementary 1st and 2nd cycles. Students per group: individual activity. How long: two 60-minute periods. Where: in class. When: before visiting the Planetarium. Type of activity: discovery led by the teacher. Key words: constellations — stars — legends — mythology. Skills honed: observing, classifying, inventing concepts, researching, developing motor skills, writing, communicating, fostering creativity. Starting Point What is a constellation? What picture does a group of stars evoke? Can I create my own constellation and think up a story about it? Preconceptions Students, particularly younger ones, might not know what a constellation is. They may also believe that the constellations are the same for all people on Earth and that everyone who looks at a specific group of stars sees the same thing in it. Basic Concepts From time immemorial, people have pondered the heavens. In the patterns formed by neighbour- ing stars, different cultures have seen animals, mythical creatures, legendary heroes, and objects of cultural importance. These groups of randomly linked stars are known as constellations. Creating a Constellation © 2000 Planétarium de Montréal — 2001.12.08 1 Goals Students create their own constellation from a group of stars and invent stories explaining their constellation. They then compare their creations with what other students have thought up and what other cultures have seen in the same group of stars. By the end of this activity, students should be able to: • Deﬁ ne constellation (a pattern formed by a group of stars). • Create a constellation using a speciﬁ c group of stars. • Make up a brief story about their constellation.

Educator's Guide: Orion

It consists of a humorous 24-minute show and educator’s package. The Orion Educator’s Guide is designed for Planetarians, Teachers, and parents. The information is researched, organized, and laid out so that the educator need not spend hours coming up with lesson plans or labs. This has already been accomplished by certified educators. The guide is written to alleviate the fear of space and the night sky (that many elementary and middle school teachers have) when it comes to that section of the science lesson plan. It is an excellent tool that allows the parents to be a part of the learning experience. The guide is devised in such a way that there are plenty of visuals to assist the educator and student in finding the Winter constellations.

In This Exercise, You Will Learn Some of the Stars That Make up Patterns in the Sky
PHYS 1830 - Perspectives on the Universe Winter 2015 PLANETARIUM EXERCISE In this exercise, you will learn some of the stars that make up patterns in the sky. These are properly known as asterisms. Constellations, on the other hand, are defined as 88 regions or patches of sky that are officially designated by the International Astronomical Union (IAU). Constellations often contain the familiar patterns of stars that are the asterisms, but constellations are usually identified by their Latin name. For example, the asterism of the Big Dipper is contained within the constellation of Ursa Major, the Greater Bear. You will also be introduced to the astronomical coordinate system that is most commonly used to describe positions of objects in the sky: the equatorial coordinate system. Part 1: Sketching You will sketch several asterisms on a single page. Draw a line across the bottom of the page to indicate the position of the horizon. Label this line with the cardinal points. Draw a cross near the top of your sketch to represent the position of the zenith. Label this point. Lightly draw in the position of the meridian and label it. For each sketch, label the time for which the planetarium is set and record your location within the dome. Use circles to mark the relative positions of the stars. The size of the circle should reflect the relative brightness with larger circles indicating brighter stars. Use straight lines to connect the relevant stars to draw the asterism shape. Sketch #1: Big Dipper, Little Dipper, and Cassiopeia Label the asterism/constellation name.

Winter Constellations Orion
Night Sky 101: Winter Constellations Orion Orion is possibly the most well-known constellation, apart from The Big and Little Dipper. Easily recognizable by the three bright stars that form the “belt of Orion,” the constellation is, in reality, much larger. The two brightest stars in Orion are called Betelgeuse and Rigel. Betelgeuse has a distinct red tint, which makes it easy to tell them apart. Betelgeuse may soon go completely supernova. Astronomers suspect that this supernova will not affect the Earth, but may cause a double shadow to be cast on the Earth’s surface for up to two weeks. Orion is identified as the hunter by the Greeks. According to the myth, Orion was the son of the god Posiedon and Euryale, queen of the Amazons. Orion inherited his mothers talents and became the greatest hunter in the whole world. However, he boasted about this repeatedly, and was killed by a small scorpion (Scorpius), who stung him on the ankle. Canis Major and Canis Minor According to Greek mythology, Canis Major and Minor represent Orion’s faithful hunting companions. Canis Major appears to be chasing the rabbit constellation, Lepus, in the night sky. Canis Major is home to the sky’s brightest star, Sirius, also called “The Dog Star.” Sirius is a blue star, but appears to be many different colors and has been repeatedly mistaken as a UFO. One of the most unique celestial objects in Canis Major is the colliding spiral galaxies, NGC 2207 and IC 2163. The larger galaxy is in the process of pulling stars and remaining material from the smaller galaxy.
