We were able to apply the convex inversion method to more than 5,000 asteroids with more than 60 good measurements in order to derive their sidereal rotation periods, spin axis orientations, and shape models. We derive unique spin state and shape solutions for 760 asteroids, including 163 new determinations. This corresponds to a success rate of about 15%, which is significantly higher than the success rate previously achieved using photometry from surveys. -

First He Got Pluto Demoted and Now He's Taking on Hollywood in One

This journey through contemporary American popular culture uses science as the signposts as he focuses on movies and TV shows that most people know and love while offering a new appreciation of such moments as Luke Skywalker looking up at the double sunset. A man that has held his own with Jon Stewart on The Daily Show and Stephen Colbert on the Colbert Report, Tyson stresses this is not a university lecture. In an interview for the Broward Center program Spotlight, he said, “I want you to leave and think, 'Boy, I learned a lot!' and enjoyed every minute of it. That's how I want you to feel. I think you'll enjoy it because I think the universe is hilarious!" Tyson has been honored in many fields from academia to being named by the editors of Time Magazine as a Top Tweeter. -

Invisible Light 10. Between the Planets 11. Exoplanet Earth 12. Reflections on the Cosmic Perspective Acknowledgments Index PREFACE In recent years, no more than a week goes by without news of a cosmic discovery worthy of banner headlines. While media gatekeepers may have developed an interest in the universe, this rise in coverage likely comes from a genuine increase in the public’s appetite for science. Evidence for this abounds, from hit television shows inspired or informed by science, to the success of science fiction films starring marquee actors, and brought to the screen by celebrated producers and directors. And lately, theatrical release biopics featuring important scientists have become a genre unto itself. There’s also widespread interest around the world in science festivals, science fiction conventions, and science documentaries for television. The highest grossing film of all time is by a famous director who set his story on a planet orbiting a distant star. And it features a famous actress who plays an astrobiologist. While most branches of science have ascended in this era, the field of astrophysics persistently rises to the top. I think I know why. At one time or another every one of us has looked up at the night sky and wondered: What does it all mean? How does it all work? And, what is my place in the universe? If you’re too busy to absorb the cosmos via classes, textbooks, or documentaries, and you nonetheless seek a brief but meaningful introduction to the field, I offer you Astrophysics for People in a Hurry. -

LIGHTCURVE ANALYSIS FOR 19848 YEUNGCHUCHIU Kwong W. Yeung Desert Eagle Observatory P.O. Box 105 Benson, AZ 85602 [email protected] (Received: 19 Feb) The lightcurve for asteroid 19848 Yeungchuchiu was measured using images taken in November 2005. The lightcurve was found to have a synodic period of 3.450±0.002h and amplitude of 0.70±0.03m. Asteroid 19848 Yeungchuchiu was discovered in 2000 Oct. by the author at Desert Beaver Observatory, AZ, while it was about one degree away from Jupiter. It is named in honor of my father, The amplitude of 0.7 magnitude indicates that the long axis is Yeung Chu Chiu, who is a businessman in Hong Kong. I hoped to about 2 times that of the shorter axis, as seen from the line of sight learn the art of photometry by studying the lightcurve of 19848 as at that particular moment. Since both the maxima and minima my first solo project. have similar “height”, it’s likely that the rotational axis was almost perpendicular to the line of sight.

Tyson Brings the Universe Down to Earth
Tulane University Tyson brings the universe down to Earth April 15, 2014 12:00 PM Fran Simon [email protected] Tulane University Campus Programming (TUCP) went out with a big bang on Monday (April 14), presenting astrophysicist Neil deGrasse Tyson for the last Direction program of the academic year. Astrophysicist Neil deGrasse Tyson, on a mission to bring science to the general public, rocks the audience in McAlister Auditorium, with hundreds more crammed into the overflow room in Kendall Cram Lecture Hall to watch live streaming of his lecture. (Photo by Ryan Rivet) Tyson is host and editor of “COSMOS: A Space-Time Odyssey,” airing on FOX (a counter-intuitive choice, Tyson acknowledged) and the National Geographic Channel. The show is a sequel to “Cosmos: A Personal Voyage,” the 1980 PBS series hosted by Carl Sagan, previously the world's best-known astrophysicist. Tyson also hosted PBS's “NOVA ScienceNOW” and launched the popular “StarTalk” radio program. With those programs and many more appearances on TV, the director of the Hayden Planetarium in New York drew thousands to his talk, “This Just In.” Working the stage like a consummate stand-up comedian, Tyson bopped from cosmic subject to cosmic subject: the controversy over demoting Pluto from planetary status (“Pluto is still not a planet. Get over it.”), the proposal to make the Bible the official state book of Louisiana, the “blood moon” this week, the continuing expansion of the universe due to the Big Bang (“It's still happening. Get over it.”), the Higgs Boson “God” particle, life on Mars, his “discovery” of the planet Krypton in the Constellation Corvus, asteroids ⦠his topics were seemingly as vast as the cosmos.
