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.

Desert Sky Observer Volume 32 Antelope Valley Astronomy Club Newsletter February 2012 Up-Coming Events February 10: Club Meeting* February 11: Moon Walk @ Prime Desert Woodlands February 13: Executive Board Meeting @ Don’s house February 18: Telescope Night and Star Party @ Devil's Punchbowl * Monthly meetings are held at the S.A.G.E. Planetarium on the Cactus School campus in Palmdale, the second Friday of each month. The meeting location is at the northeast corner of Avenue R and 20th Street East. Meetings start at 7 p.m. and are open to the public. Please note that food and drink are not allowed in the planetarium President Don Bryden Well I gave a star party and no one showed up! Not that I can blame them – it was raining and windy and cold – it even hailed! Still I dragged out the scope and got it ready to go. Briefly, between the clouds I looked at Jupiter and it was quite a treat. The Galilean moons were all tight to the planet either coming from just in front or behind. It gave a bejeweled look like a large ruby surrounded by four small diamonds. Even with the winds and clouds the sky was surprisingly steady and I went as high as 260x with ease, exposing the shadow of Europa transiting the planet. But soon more clouds came and inside we had a nice fire so I put the Artist's rendering DVD “400 Years of the Telescope” on and settled in for the night. My daughter had a few friends over after a skating party that afternoon and later when I went out for one more look they came out to see what was up. -

Lurking in the Shadows: Wide-Separation Gas Giants As Tracers of Planet Formation
Lurking in the Shadows: Wide-Separation Gas Giants as Tracers of Planet Formation Thesis by Marta Levesque Bryan In Partial Fulfillment of the Requirements for the Degree of Doctor of Philosophy CALIFORNIA INSTITUTE OF TECHNOLOGY Pasadena, California 2018 Defended May 1, 2018 ii © 2018 Marta Levesque Bryan ORCID: [0000-0002-6076-5967] All rights reserved iii ACKNOWLEDGEMENTS First and foremost I would like to thank Heather Knutson, who I had the great privilege of working with as my thesis advisor. Her encouragement, guidance, and perspective helped me navigate many a challenging problem, and my conversations with her were a consistent source of positivity and learning throughout my time at Caltech. I leave graduate school a better scientist and person for having her as a role model. Heather fostered a wonderfully positive and supportive environment for her students, giving us the space to explore and grow - I could not have asked for a better advisor or research experience. I would also like to thank Konstantin Batygin for enthusiastic and illuminating discussions that always left me more excited to explore the result at hand. Thank you as well to Dimitri Mawet for providing both expertise and contagious optimism for some of my latest direct imaging endeavors. Thank you to the rest of my thesis committee, namely Geoff Blake, Evan Kirby, and Chuck Steidel for their support, helpful conversations, and insightful questions. I am grateful to have had the opportunity to collaborate with Brendan Bowler. His talk at Caltech my second year of graduate school introduced me to an unexpected population of massive wide-separation planetary-mass companions, and lead to a long-running collaboration from which several of my thesis projects were born. -

This belt is considered special because it is where the sun, the moon, and the planets all move. The word zodiac means “circle of figures” or “circle of life”. As the earth revolves around the sun, different parts of the sky become visible. Each month, one of the 12 constellations show up above the horizon in the east and disappears below the horizon in the west. If you are born under a particular sign, the constellation it is named for can’t be seen at night. Instead, the sun is passing through it around that time of year making it a daytime constellation that you can’t see!

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. DSO’s ● ***M42 “Orion Nebula” (Neb) with Trapezium A stellar nursery where new stars are being born, perhaps a thousand stars. These are immense clouds of interstellar gas and dust collapse inward to form stars, mainly of ionized hydrogen which gives off the red glow so dominant, and also ionized greenish oxygen gas. The youngest stars may be less than 300,000 years old, even as young as 10,000 years old (compared to the Sun, 4.6 billion years old). 1300 ly. 1 ● *M43--(Neb) “De Marin’s Nebula” The star-forming “comma-shaped” region connected to the Orion Nebula. ● *M78--(Neb) Hard to see.
