Art Matching
Art Matching Program Type: Demonstration or Classroom Audience Type: Grade 4–adult Program Description: Students explore how artists from different cultures have used art to represent space-related phenomena. Topics: Moon, space travel, art, stars, sky-watching Process Skills Focus: Critical thinking, observing, creativity. LEARNING OBJECTIVES For Next Generation Science Standards alignment, see end of outline. • Many artists are inspired by astronomy and the universe. • Cultures often have their own interpretations of the sky and celestial phenomena. • Art is one of many ways to capture our observations of and reflections on the sky. TIME REQUIRED Advance Prep Set Up Activity Clean Up 15 minutes 5 minutes 10 minutes 5 minutes SITE REQUIREMENTS • Table or other flat surface • Chairs (optional, but helpful for elderly or young audiences) Art Matching 1 Lenses on the Sky OMSI 2017 PROGRAM FORMAT Segment Format Time Introduction Large group discussion 2 min Art Matching Group Activity 5 min Wrap-Up Large group discussion 3 min SUPPLIES Permanent Supplies Amount Notes Laminated pages showing the artists 5 and their work Laminated cards showing 5 astronomical images ADVANCE PREPARATION • Print out, cut, and laminate the pages showing the artists and their work (at the end of the document). • Print out, cut, and laminate the five cards showing the astronomical images (at the end of the document). • Complete the activity to familiarize yourself with the process.

Filter Performance Comparisons for Some Common Nebulae
Filter Performance Comparisons For Some Common Nebulae By Dave Knisely Light Pollution and various “nebula” filters have been around since the late 1970’s, and amateurs have been using them ever since to bring out detail (and even some objects) which were difficult to impossible to see before in modest apertures. When I started using them in the early 1980’s, specific information about which filter might work on a given object (or even whether certain filters were useful at all) was often hard to come by. Even those accounts that were available often had incomplete or inaccurate information. Getting some observational experience with the Lumicon line of filters helped, but there were still some unanswered questions. I wondered how the various filters would rank on- average against each other for a large number of objects, and whether there was a “best overall” filter. In particular, I also wondered if the much-maligned H-Beta filter was useful on more objects than the two or three targets most often mentioned in publications. In the summer of 1999, I decided to begin some more comprehensive observations to try and answer these questions and determine how to best use these filters overall. I formulated a basic survey covering a moderate number of emission and planetary nebulae to obtain some statistics on filter performance to try to address the following questions: 1. How do the various filter types compare as to what (on average) they show on a given nebula? 2. Is there one overall “best” nebula filter which will work on the largest number of objects? 3. -

In one myth, Orion boasted he would kill all the wild animals on the earth. But, the earth goddess Gaia, who was the protector of all animals, produced a gigantic scorpion, whose body was so heavily encased that Orion was unable to pierce through the armour, and was himself stung to death. His companion Artemis was greatly saddened and arranged for Orion to be immortalised among the stars. Scorpius, the scorpion, was placed on the opposite side of the sky so that Orion would never be hurt by it again. To this day, Orion is never seen in the sky at the same time as Scorpius.

Supernova Shocks in Molecular Clouds: Velocity Distribution of Molecular Hydrogen William T
Draft version September 6, 2019 Typeset using LATEX preprint2 style in AASTeX63 Supernova Shocks in Molecular Clouds: Velocity Distribution of Molecular Hydrogen William T. Reach,1 Le Ngoc Tram,1 Matthew Richter,2 Antoine Gusdorf,3 Curtis DeWitt,1 1Universities Space Research Association, MS 232-11, Moffett Field, CA 94035, USA 2University of California, Davis, CA USA 3Observatoire de Paris, Ecole´ normale sup´erieure, Sorbonne Universit´e,CNRS, LERMA, 75005 Paris, France ABSTRACT Supernovae from core-collapse of massive stars drive shocks into the molecular clouds from which the stars formed. Such shocks affect future star formation from the molecu- lar clouds, and the fast-moving, dense gas with compressed magnetic fields is associated with enhanced cosmic rays. This paper presents new theoretical modeling, using the Paris-Durham shock model, and new observations at high spectral resolution, using the Stratospheric Observatory for Infrared Astronomy (SOFIA), of the H2 S(5) pure rota- tional line from molecular shocks in the supernova remnant IC 443. We generate MHD models for non-steady-state shocks driven by the pressure of the IC 443 blast wave into gas of densities 103 to 105 cm−3. We present the first detailed derivation of the shape of the velocity profile for emission from H2 lines behind such shocks, taking into account the shock age, preshock density, and magnetic field. For preshock densities 103{105 −3 cm , the H2 emission arises from layers that extend 0.01{0.0003 pc behind the shock, respectively. The predicted shifts of line centers, and the line widths, of the H2 lines range from 20{2, and 30{4 km s−1, respectively. -

Í flestum tilfellum voru viðfangsefnin óeiginlegar breytistjörnur, aðallega myrkvatvístirni, en einnig var fylgst með nokkrum fjarreikistjörnum. Í mælingum á myrkvatvístirnum og fjarreikistjörnum er markmiðið að tímasetja myrkva og þvergöngur. Einnig er sagt frá niðurstöðum á nándarstjörnunni Ross 248 og athugunum á lausþyrpingunni NGC 7790 og breytistjörnum í nágrenni hennar. Markmið mælinga á nándarstjörnu og lausþyrpingum er að meta fjarlægðir eða aðra eiginleika fyrirbæranna. Að lokum eru kynntar athuganir á litrófi nokkurra bjartra stjarna. Í samantektinni er sagt frá hverju viðfangsefni í sérköflum. Þessi samantekt er sú þriðja um stjörnuathuganir sem er gefin út af Náttúrustofu Suðausturlands. Niðurstöður hafa verið sendar í alþjóðlegan gagnagrunn þar sem þær, ásamt fjölda sambærilegra mæligagna frá stjörnuáhugamönnum, eru aðgengilegar stjarnvísindasamfélaginu.
