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

They've got a 26-metre radio dish, and many other instruments. It would be a great opportunity to see the equipment and meet radio astronomers, so if you live nearby, put this on your calendar.

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. 2005 September 18 M42: Wisps of the Orion Nebula John P. Gleason Explanation: The Great Nebula in Orion , an immense, nearby starbirth region , is probably the most famous of all astronomical nebulas . Here, glowing gas surrounds hot young stars at the edge of an immense interstellar molecular cloud only 1500 light-years away. In the above deep image , faint wisps and sheets of dust and gas are particularly evident. The Great Nebula in Orion can be found with the unaided eye just below and to the left of the easily identifiable belt of three stars in the popular constellation Orion . In addition to housing a bright open cluster of stars known as the Trapezium , the Orion Nebula contains many stellar nurseries . These nurseries contain hydrogen gas, hot young stars, proplyds , and stellar jets spewing material at high speeds. Also known as , the Orion Nebula spans about 40 light years and is located in the same spiral arm of our Galaxy as the Sun Tomorrow's picture: asteroid ahead Archive Index Search Calendar ...

152. Islamic Astronomy By Owen Gingerich An article by Owen Gingerich, in Scientific American, on ancient astronomy preserved and improved in 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.")

156. Magi - Early Natural Philosophers & Thinkers (and A Great Poet, Too) Introduction to contributions by AlKhwarismi, Al-Kindi, and Omar Khayyam in the fields of mathematics, astronomy, medicine, and optics. Period of time discussed is from around 680 AD to 1120 AD in the present day Middle East. http://www.perceptions.couk.com/magi.html

comment + criticism welcome "Perceptions" ITEM Ray Dickenson Magi early Eastern philosophers (and a great poet) Here's picture of Taqi al-Din ibn Muhammad ibn Ma‘ruf, Director of Istanbul Observatory. He's holding the astrolabe, an early analog computer, which he's discussing with another senior astronomer. [Just to confuse us, Assyriologists also refer to Mesopotamian constellation-lists - i.e. text documents - as `astrolabes'] Below, a `universal' astrolabe - for all latitudes - which can solve the celestial navigation problems, including `time'. Astrolabes were developed from c. 900 CE in the Islamic world, which inherited both the genius and the records of the Babylonians. In the picture there are only two western instruments - a celestial globe (front center) and a carriage-clock (middle far right). Al-Khwarizmi Al-Kindi Omar Khayyam Al-Khwarizmi (c. 680 - 750 CE) Al-Khwarizmi (c. 680 - 750 CE) Abu Abdullah Mohammed ibn Musa al-Khwarizmi al-Magusa was possibly the most influential of the intellectually adaptive Arab mathematicians ... at a time when the Europeans were trapped in a primitive fundamentalism, with its resulting intolerance and persecution of (secular) knowledge"
