Howdy, everyone! We've had a few changes in the presentation schedule for Astronomy Weekend; I just wanted to send this out to everyone so that you have a better idea of who else is talking (and for those who might want to come hear them.) :-) This may still not be final, but it's getting close. Kudos to Terri Finch and Howard Israel for all of their work encouraging and organizing speakers and volunteers for this event. The presentations are all free with the price of admission to the Arizona Science Center (members get in free, adults $8). There will be solar telescopes set up on Saturday and Sunday in Heritage Square, and an evening observing session in Heritage Square on Sunday (roughly 7pm to 9 pm). There will also be a large number of exhibits set up by individuals, clubs, observatories, and companies, and many handouts. Volunteers and speakers, please let me know if you have any questions that haven't been answered yet.

Robin Fergason, Research Assistant, Mars Space Flight Facility, Department of Geological Sciences, Arizona State University Using Elephants to Study Cosmic Crabs: Using Exotic Telescopes to Study the Most Violent Events in the Universe (Saturday at 1:30 p.m. in the Light & Color Gallery) The most dynamic astrophysical phenomena are best observed by the new astronomies at X-ray and gamma-ray wavelengths. The sources that exhibit these properties are some of the most exciting members of the cosmic zoo: stars that explode catastrophically, supermassive black holes at the centers of galaxies, jets of relativistic particles from stars and galaxies that are pointed in the direction of the Solar System. They constitute cosmic laboratories where the normal laws of physics are tested in their extremes. The classic example of such objects is the Crab Nebula. Recently it has become possible to observe cosmic catastrophes in which very high energy gamma rays, some million million times the energy of a photon of light, are emitted. It is almost impossible to create such gamma rays here on earth yet they are apparently created with ease in the chaos of these cosmic sources. This extreme form of astronomy is pursued with a strange technique that uses unusual ground-based telescopes. These observations give new insights into particle acceleration and may ultimately supply the answer to one of the most perplexing puzzles in astrophysics, the origin of the cosmic radiation. Dr. Trevor Weekes, Harvard-Smithsonian Center for Astrophysics Dr. Weekes is a high energy gamma ray astronomer, and has been an astrophysicist at the Whipple Observatory, Smithsonian Astrophysical Observatory since 1967 The World's Most Powerful Telescope and the Search for ET (Saturday at 4 p.m. and Sunday at 5 p.m. in the Flinn Theater) In the next three years, the Large Binocular Telescope (LBT) will go into operation on Mt. Graham near Safford, Arizona. This telescope has two giant mirrors, each 28 ft in diameter, with the light collecting power of a single mirror or 39 ft. Utilizing state-of-the-art adaptive optics, the LBT will acquire images that are ten times sharper than Hubble. With these optics and other techniques, University of Arizona astronomers expect to be able to directly image (or see) planets orbiting nearby stars. This talk is aimed popular audiences and will describe the work in progress on the LBT and the search for planets around other stars. Dr. Peter Wehinger is a Staff Astronomer at the Steward Observatory, of the University of Arizona. He is involved in the development of the LBT and the Mirror Lab were the world's largest mirrors are being spun cast.
