POPS"The World Will Not End on Dec. 21, 2012" Morrison said he tries to reassure people that their fears are groundless, but has received so many inquiries that he has posted a list of 10 questions and answers on the website of the Astronomical Society of the Pacific (www.astrosociety.org). Titled "Doomsday 2012, the Planet Nibiru and Cosmophobia," the article breaks down the sources of the hysteria and assures people that the ancients didn't actually know more about the cosmos than we do. "The world will not come to an end on Dec. 21, 2012," E.C. Krupp, director of Los Angeles' Griffith Observatory, declared in a statement released Thursday by the observatory and Sky & Telescope magazine. Krupp debunks the 2012 doomsday idea in the cover story of the magazine's November issue. Morrison said he attributes the excitement to the conflation of several items into one mega-myth. One is the persistent Internet rumor that a planet called Nibiru or Planet X is going to crash into the Earth. . .

POPSGalileo's Spyglass Using ever-more powerful telescopes over the next year, Galileo observed that the Moon was not perfectly smooth, as claimed by Aristotle, but cratered and mountainous. He spotted hundreds of stars previously untouched by human eyes. More critically, he discovered the four inner satellites of Jupiter - still known as the "Galilean moons" in his honour - and learnt that Venus, Earth's closest planet, goes through a full range of phases. Put together, his observations validated the revolutionary theory of Nicolaus Copernicus that Earth orbits the Sun, and not the other way round. Galileo understood the implications of what he had seen, but the Catholic Church was not ready to accept such heresy. Only in 2000 did the Holy See apologise for putting Galileo on trial in 1633, forcing him to recant his ideas lest he face imprisonment or worse. The Vatican also pays tribute to him in an exhibition that opened this month. I never knew that it was only in 20

POPSSet Your Alarm For The Orionids!
"Last but not least, the display will be framed by some of the prettiest stars and planets in the night sky. In addition to Orionids, you'll see brilliant Venus, red Mars, the dog star Sirius, and bright winter constellations such as Orion, Gemini and Taurus. Even if the shower is a dud, the rest of the sky is dynamite." "According to Japanese meteor scientists Mikiya Sato and Jun-ichi Watanabe, 2006 marked Earth's first encounter with some very old debris. "We have found that the was caused by dust trails ejected from 1P/Halley in 1266 BC, 1198 BC, and 911 BC," they wrote in the August 2007 edition of Publications of the Astronomical Society of Japan. In their paper "Origin of the 2006 Orionid Outburst," Sato and Watanabe used a computer to model the structure and evolution of Halley's many debris streams stretching back in time as far as 3400 years. The debris that hit Earth in 2006 was among the oldest they studied and was rich in large fireball-producin

POPSHerschel scans hidden Milky Way Herschel intends to study large regions of the Milky Way in its combined Spire-Pacs scanning mode. The instruments will, of course, also work independently. The mission is due to go into routine operations in the next few weeks. However, its third instrument is currently down after experiencing a fault. Engineers can switch to a back-up system to reactivate the Heterodyne Instrument for the Far Infrared (HiFi), but they do not intend to do that until they have satisfied themselves the cause the anomaly is properly understood. The Dutch-led HiFi is a spectrometer that will identify elements and molecules in the clouds of gas and dust which give rise to stars.
