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. -
VOLANS-CARINA: a NEW 90 Myr OLD STELLAR ASSOCIATION at 85 Pc

We compile a list of 19 likely members from Gaia DR2 with spectral types B8{M2, and 46 additional candidate members from Gaia DR2, 2MASS and AllWISE with spectral types A0{M9 that require +5 further follow-up for confirmation. We find an isochronal age of 89−7 Myr based on MIST isochrones calibrated with Pleiades members. This new association of stars is slightly younger than the Pleiades, with less members but located at a closer distance, making its members ' 3 times as bright than those of the Pleiades on average. It is located further than members of the AB Doradus moving group which have a similar age, but it is more compact on the sky which makes it less prone to contamination from random field interlopers. -
Virgil, Aeneid 11 (Pallas & Camilla) 1–224, 498–521, 532–96, 648–89, 725–835 G
Virgil, Aeneid 11 (Pallas & Camilla) 1–224, 498–521, 532–96, 648–89, 725–835 G Latin text, study aids with vocabulary, and commentary ILDENHARD INGO GILDENHARD AND JOHN HENDERSON A dead boy (Pallas) and the death of a girl (Camilla) loom over the opening and the closing part of the eleventh book of the Aeneid. Following the savage slaughter in Aeneid 10, the AND book opens in a mournful mood as the warring parti es revisit yesterday’s killing fi elds to att end to their dead. One casualty in parti cular commands att enti on: Aeneas’ protégé H Pallas, killed and despoiled by Turnus in the previous book. His death plunges his father ENDERSON Evander and his surrogate father Aeneas into heart-rending despair – and helps set up the foundati onal act of sacrifi cial brutality that caps the poem, when Aeneas seeks to avenge Pallas by slaying Turnus in wrathful fury. Turnus’ departure from the living is prefi gured by that of his ally Camilla, a maiden schooled in the marti al arts, who sets the mold for warrior princesses such as Xena and Wonder Woman. In the fi nal third of Aeneid 11, she wreaks havoc not just on the batt lefi eld but on gender stereotypes and the conventi ons of the epic genre, before she too succumbs to a premature death. In the porti ons of the book selected for discussion here, Virgil off ers some of his most emoti ve (and disturbing) meditati ons on the tragic nature of human existence – but also knows how to lighten the mood with a bit of drag. -
THE CONSTELLATION MUSCA, the FLY Musca Australis (Latin: Southern Fly) Is a Small Constellation in the Deep Southern Sky
THE CONSTELLATION MUSCA, THE FLY Musca Australis (Latin: Southern Fly) is a small constellation in the deep southern sky. It was one of twelve constellations created by Petrus Plancius from the observations of Pieter Dirkszoon Keyser and Frederick de Houtman and it first appeared on a 35-cm diameter celestial globe published in 1597 in Amsterdam by Plancius and Jodocus Hondius. The first depiction of this constellation in a celestial atlas was in Johann Bayer's Uranometria of 1603. It was also known as Apis (Latin: bee) for two hundred years. Musca remains below the horizon for most Northern Hemisphere observers. Also known as the Southern or Indian Fly, the French Mouche Australe ou Indienne, the German Südliche Fliege, and the Italian Mosca Australe, it lies partly in the Milky Way, south of Crux and east of the Chamaeleon. De Houtman included it in his southern star catalogue in 1598 under the Dutch name De Vlieghe, ‘The Fly’ This title generally is supposed to have been substituted by La Caille, about 1752, for Bayer's Apis, the Bee; but Halley, in 1679, had called it Musca Apis; and even previous to him, Riccioli catalogued it as Apis seu Musca. Even in our day the idea of a Bee prevails, for Stieler's Planisphere of 1872 has Biene, and an alternative title in France is Abeille. When the Northern Fly was merged with Aries by the International Astronomical Union (IAU) in 1929, Musca Australis was given its modern shortened name Musca. It is the only official constellation depicting an insect. Julius Schiller, who redrew and named all the 88 constellations united Musca with the Bird of Paradise and the Chamaeleon as mother Eve. -
These Sky Maps Were Made Using the Freeware UNIX Program "Starchart", from Alan Paeth and Craig Counterman, with Some Postprocessing by Stuart Levy
These sky maps were made using the freeware UNIX program "starchart", from Alan Paeth and Craig Counterman, with some postprocessing by Stuart Levy. You’re free to use them however you wish. There are five equatorial maps: three covering the equatorial strip from declination −60 to +60 degrees, corresponding roughly to the evening sky in northern winter (eq1), spring (eq2), and summer/autumn (eq3), plus maps covering the north and south polar areas to declination about +/− 25 degrees. Grid lines are drawn at every 15 degrees of declination, and every hour (= 15 degrees at the equator) of right ascension. The equatorial−strip maps use a simple rectangular projection; this shows constellations near the equator with their true shape, but those at declination +/− 30 degrees are stretched horizontally by about 15%, and those at the extreme 60−degree edge are plotted twice as wide as you’ll see them on the sky. The sinusoidal curve spanning the equatorial strip is, of course, the Ecliptic −− the path of the Sun (and approximately that of the planets) through the sky. The polar maps are plotted with stereographic projection. This preserves shapes of small constellations, but enlarges them as they get farther from the pole; at declination 45 degrees they’re about 17% oversized, and at the extreme 25−degree edge about 40% too large. These charts plot stars down to magnitude 5, along with a few of the brighter deep−sky objects −− mostly star clusters and nebulae. Many stars are labelled with their Bayer Greek−letter names. Also here are similarly−plotted maps, based on galactic coordinates. -

Since the names and designs of the wheels are sometimes difficult to describe, we recommend obtaining the stamping number off the wheel before trying to order. Generally this stamping number will be a seven-digit number, found behind the center cap, or on the inside rear of the wheel. Before ordering wheels, it is a good idea to ask for the stamping number. If you find a wheel where the stamping number is not listed below, we can quickly update the list. 930 = Silver 931 = Dark Silver 932 = Anthracite 933 = Champagne 934 = White Silver 936 = Bright Silver Stamping Number Spare Part Number Size Name Color Code 1394934 1394935 6.5x15 Spica Dark Silver 931 3524154 9451348 7x17 Arrakis Bright Silver 936 3524161 9451552 6.5x15 Ariane White Silver 935 3524367 9451345 7x16 Regulus Silver 930 3529645 3529650 7x17 Titan Anthracite 932 3545745 9166116 6.5 x 16 Columba Anthracite 932 Produced in the USA and available as an electronic document.

The structure, at a characteristic redshift of 12,000 km s−1, has a density peak coincident with the celestial South Pole. This structure, the largest contiguous feature in the local volume and comparable to the Sloan Great Wall at half the distance, is given the name the South Pole Wall. 1.
