Astronomy Picture of the Day Discover the cosmos! Each day a different image or photograph of our fascinating universe is featured, along with a brief explanation written by a professional astronomer. 2000 February 26 Impact: 65 Million Years Ago Credit: courtesy V.L. Sharpton, LPI Explanation: What killed the dinosaurs? Their sudden disappearance 65 million years ago, along with about 70 percent of all species then living on Earth, is known as the K-T event (Cretaceous-Tertiary Mass Extinction event). Geologists and paleontologists often entertain the idea that a large asteroid or comet impacting the Earth was the culprit. In such a cosmic catastrophe, the good(!) news would be that the impact would generate firestorms, tidal waves, earthquakes, and hurricane winds. As for the bad news ... debris thrown into the atmosphere would have a serious global environmental consequences, creating extended periods of darkness, low temperatures, and acid rains - resulting in a planet-wide extinction event. In 1990, dramatic support for this theory came from cosmochemist Alan Hildebrand's revelation of a 65 million year old, 112 mile wide ring structure

Search Space / Astronomy From Nick Greene Your Guide to Space / Astronomy Apollo 1 Fire - Early Blow to the Space Race It was January 27, 1967 and the crew of Apollo/Saturn 204 (more commonly known as Apollo 1 mission) were training for the first crewed Apollo flight, an Earth orbiting mission scheduled to be launched on 21 February. They were involved in a "plugs-out" test, with the Command Module mounted on the Saturn 1B on the launch pad just as in the actual launch, but the rocket was not fueled. This test was a simulation, going through an entire countdown sequence. At 6:31 PM, a voice (later believed to be Roger Chaffee) exclaimed, “Fire, I smell fire.” Two seconds later, Ed White voice came over the circuit, “Fire in the cockpit.” The final voice transmission from crew was very garbled. “They’re fighting a bad fire—let’s get out. Open ‘er up” or, “We’ve got a bad fire—let’s get out. We’re burning up” or, “I’m reporting a bad fire. I’m getting out.” The transmission ended with cry of pain, perhaps from pilot. Read more about the Apollo 1 fire.

112. Boy Scout Astronomy Merit Badge Program Program, fees, and badge requirements for offering by the Ritter PlanetariumBrooks Observatory of Toledo, Ohio. http://www.rpbo.utoledo.edu/bscouts.html

The Ritter Planetarium-Brooks Observatory Astronomy Merit Badge Program is based on the requirements to earn an Astronomy Merit Badge. The program includes a tour and use of the hands-on displays in our lobby, a specialized planetarium program, and either a tour of the Ritter 1-Meter Telescope , or observing at the Brooks Observatory , weather permitting. Scouts are also given a helpful workbook ( view a 4 page sample - requires Acrobat) based on the badge requirements, and each group is given a useful star and planet locator to keep and use during future stargazing. Astronomy Merit Badge Programs will be offered*: Thursday, September 18, 2003 Saturday, October 25, 2003 Wednesday, November 12, 2003 Saturday, December 13, 2003 All programs begin at 6:30pm and last 2 1/2 to 3 hours. Seating is limited! If your troop would like to attend one of our Astronomy Merit Badge Programs please RSVP in advance. Please contact the Planetarium Office at (419) 530-2650, Mondays through Fridays, 9:00am - 5:00pm to schedule your troop. Admission is $9.00 per person including all attending adults. Note: Please keep in mind that while this program covers most of the Astronomy Merit Badge requirements, it does not complete them all. Scouts will still need to complete several activities. Those activities that are not completed by the program will be covered by planetarium staff. Additionally, no planetarium staff are Merit Badge Counselors, and therefore are not qualified to sign off on a scout's requirements. If you have any further questions about this program, please contact the Associate Director

The image was taken using the National Optical Astronomy Observatory's 0.9 metre WIYN at Kitt Peak, with the Mosaic I camera. The small star cluster at the lower right of the image is Melotte 72. Comet NEAT was discovered in August 24, 2001 by the Near Earth Asteroid Tracking system managed by NASA's JPL.

But new research using the Gemini Observatory in Hawaii shows that they live in some of the more boring galaxies in the Universe. Under the current theories, the powerful twin 8-metre telescopes should have found enormous galaxies in chaos, but they didn't. Only one galaxy could actually be detected, and it wasn't much different from our own Milky Way galaxy.

Tectron Collimation Tools Imagine a book nearly eight inches thick, containing thousands of pages and photographs - all on your favorite hobby. Now imagine that every three months another 68 page chapter and another hundred plus photos are added to this book. This is Amateur Astronomy Magazine! Our articles are not written by professional writers. They are written by our subscribers, amateur astronomers who know their subject and their articles reflect their love of the hobby. The articles are not edited to death so they have no life left in them. We are subscriber supported. That means that we can say what we want. If a reviewer does not like a product, we can say so, since we don't bow to the almighty advertising dollar. Each issue contains 68 pages - and less than eight pages contain advertising. We only carry enough ads to help pay the bills. We cover the subjects that you will never see in the big magazines. If we don't like a telescope or book we say so. When we go to a star party we run many pages and dozens of photos, not a paragraph or two with one small photo that doesn't tell the real story. One article ran 20 pages and had 108 photos, just to do justice to the story. We carry articles that the real amateur astronomers of the world are interested in reading - not articles that are aimed at the news stand market of casual readers, or intended for professional astronomers.

Greek Astronomy The Revival of an Ancient Science One of the most powerful creations of Greek science was the mathematical astronomy created by Hipparchus in the second century B.C. and given final form by Ptolemy in the second century A.D. Ptolemy's work was known in the Middle Ages through imperfect Latin versions. In fifteenth-century Italy, however, it was brought back to life. George Trebizond, a Cretan emigre in the curia, produced a new translation and commentary. These proved imperfect and aroused much heated criticism. But a German astronomer, Johannes Regiomontanus, a protege of the brilliant Greek churchman Cardinal Bessarion, came to Italy with his patron, learned Greek, and produced a full-scale "Epitome" of Ptolemy's work from which most astronomers learned their art for the next century and more. Copernicus was only one of the celebrities of the Scientific Revolution whose work rested in large part on the study of ancient science carried out in fifteenth-century Italy.

120. Islamic Astronomy By Owen Gingerich About ancient astronomy preserved and improved by the Islamic empire. http://users.kfupm.edu.sa/phys/alshukri/PHYS215/Islamic astronomy.htm

Islamic astronomy by Owen Gingerich Scientific American , April 1986 v254 p74(10) Historians who track the development of astronomy from antiquity to the Renaissance sometimes refer to the time from the eighth through the 14th centuries as the Islamic period. During that interval most astronomical activity took place in the Middle East North Africa and Moorish Spain. While Europe languished in the Dark Ages, the torch of ancient scholarship had passed into Muslim hands. Islamic scholars kept it alight, and from them it passed to Renaissance Europe. Two circumstances fostered the growth of astronomy in Islamic lands. One was geographic proximity to the world of ancient learning, coupled with a tolerance for scholars of other creeds. In the ninth century most of the Greek scientific texts were translated into Arabic, including Ptolemy's Syntaxis , the apex of ancient astronomy. It was through these translations that the Greek works later became known in medieval Europe . (Indeed, the Syntaxis is still known primarily by its Arabic name, Almagest, meaning "the greatest.")
