March – April 2010 / Vol. 3, Issue 2 Where kids and grown-ups have fun with science and technology

News and Notes for formal and informaleducatorsThe Space Place is a NASA website for elementary school-aged kids, their teachers, and their parents. Its colorful!Its dynamic!Its fun! Its rich with science, technology, engineering, and math content!Its informal. Its meaty. Its easy to read and understand. Its also in Spanish. And its free! It has 130 (and counting) separate modules for kids, including hands-on projects, interac-tive games, animated cartoons, and amazing facts about space and Earth science and technology.

Our Milky Way Galaxy is one of at least 100 billion galaxies in the Universe. But that does not make our galaxy small or insignifi cant. The Milky Way has 200 billion to 400 billion stars! We can’t take a picture of our own galaxy, but we can study other galaxies we believe are similar, such as our neighbor, the Andromeda Galaxy. The Space Place has a lot of material to offer about our galactic home.

What’s new on spaceplace.nasa.gov . . .The Voyager 1 and Voyager 2 space-craft, launched in 1977 and still going strong, are about to break free of our solar system and be the fi rst human-made ob-jects to reach interstellar space. They will be galactic explorers! Although they aren’t expected to keep transmitting informa-tion much beyond 2025, they will still keep going. A new Amazing Fact page on The Space Place (http://tiny.cc/vgr) imagines what it might be like if some extra-terres-trials fi nd one of the Voyagers someday and play its Golden Record. Find out what is on the record that brings news of Earth to an un-known listener. Spotlight on Dr. Marc’s offeringsThe expert science advisor for The Space Place, Dr. Marc Rayman, loves to talk and write about astronomy. Marc was only 14 when he joined an adult astronomy club and met his fi rst real astronomer. His favorite galaxy, the Milky Way, is a topic in his "Phone Dr. Marc" archives. He speculates on the number of solar systems in our galaxy (http://tiny.cc/drmarc). He also explores the constellations, also all part of our galaxy (http://tiny.cc/drmarc526). In a Podcast (also available in transcript and MP3 form), Marc dis-cusses how the Milky Way got its name (http://tiny.cc/marcpod). All Dr. Marc’s explanations are in simple language so that educators can themselves answer these fascinating questions when curious students ask.Space Place en españolWith help from Engi-neer Ruth Fragoso, Dr. Marc’s discussion of solar systems and constella-tions in our galaxy are also available in Span-ish at http://tiny.cc/ss279 and http://tiny.cc/constel, respectively.For the ClassroomWe would love to be able to offer you a giant poster with a highly detailed and high-resolution Hubble Space Telescope, Spitzer Space Telescope, or Galaxy Evolution Explorer image of the beautiful barred spiral galaxy we call the Milky Way. Unfortunately, we’re just a little too close to get a good NASA Space Place: News & Notes Vol. 3, No. 2: March - April 2010 www.nasa.gov

shot of it! But, next best thing, we have several largehigh-res images you can download of the Androm-eda Galaxy, M31. Andromeda is our nearest galactic neighbor and is thought to be similar in appearance to our own Milky Way (although it’s about twice as large). You can download all these fi les at http://spaceplace.nasa.gov/en/educators/posters.First is a poster with an ultraviolet view of An-dromeda, captured by the Galaxy Evolution Explorer.Articles on the back of the poster explain how tele-scopes see back in time and why the night sky is black, in spite of 200 billion suns shining right here inthe Milky Way galaxy. Activities include crossword anword fi nd puzzles based on vocabulary in the articlesas well as a creative writing activity. The poster front is available in .pdf format for professional printing at full-size (22 x 26).Second is an 8½ x11 lithograph, with another even more dramatic view of the ultraviolet M31. On the back of the litho is a description of the galaxy andthe special insights provided by the UV view.The third print product is a large poster (25½ x 22) with multiwavelength views of Andromeda. It shows why we need telescopes that see at different wavelengths, because the information from visible, infrared and ultraviolet light, in different combinations, reveal very different characteristics of the galaxy. On the back of the poster are classroom versions of the two experiments that originally spawned the discoveryof infrared and ultraviolet light at the turn of the 19th century. For After SchoolPrint and read aloud "Lucy’s Planet Hunt: Or, how to see things in a different light." It is the story, in verse and cartoon illustrations of a girl who dreamed of fi nd-ing other Earth-like planets in our galaxy. She made her dream come true by becoming a sci-entist and helping to design and build an infrared space telescope! (http://tiny.cc/lucy208).Time to Celebrate March is Listening Awareness Month. One can learn a lot by just listening, especially to such rich material as in the Podcasts at The Space Place (http://tiny.cc/marcpod).d March 15: Absolutely Incredible Kid Day. We love , this "holiday" at The Space Place! We wish we could write a letter of support and encouragement to every one of our Web site visitors. We can’t. But you can—at least to some of them!March 20: International Earth Day. Make "Gummy Greenhouse Gas" molecules and learn about the greenhouse effect on our planet. Also in Spanish. (http://tiny.cc/gumdrop).April 10: Encourage a Young Writer Day. Ask them to write about a black and starry night or a brilliantblue-sky day. (http://tiny.cc/bluesApril 19: Humorous Day. Read the online or print version of "The First Annual Planet Awards." A cross between the Miss America Pageant and the Os-cars, this "award show" gives each planet a chance to prove its worthiness for an award. (http://tiny.cc/planetawards).April 24: Astronomy Day. A good day to play the Spitzer Concentration game and learn to recognize some exciting astronomical objects in our galaxy. Also in Spanish. (http://tiny.cc/concentration822) .And another thing . . .Our Scouting pages have found wider uses than only for Scouts and their leaders. Teachers, as well, have told us this resource has given them ideas for rewarding projects for their students. In cooperation with the scouting organizations, we have identifi ed activities on The Space Place that partially or completely fulfi ll specifi c achievement requirements.
