One Full Year of "What's Up This Week"
Oct 17, 2005 - I'd just like to take a moment and congratulate Tammy Plotner on wrapping up a full year's worth of What's Up This Week articles. Woohoo! She's never missed a week and never been late. Anyway, if you've appreciated her column, take a moment and drop her an email. I'm sure she'll really appreciate it (and curse me for filling up her email box). Hah! Check out the full archive here.

Here's to many more years of Tammy's wonderful, weekly columns.

P.S. I just did an interview with UK psychic debunker Tony Youens for the Skepticality podcast. I figured I'd pitch in to help out Derek and Swoopy while Derek continues his recovery. Check it out. Don't worry, I'll be updating my Podcast shortly too. (Full Story)

Oct 17, 2005 - Greetings, fellow SkyWatchers! The time for Mars is now as even small telescopes can see a wealth of details. Mid-week will offer some viewers the chance to see a very rare eclipse of a bright star by an asteroid! We'll explore bright stars, open clusters, watch occultations and welcome back the children of Comet Halley. So turn your eyes to the skies, because....

Chinese Astronauts Return Safely to Earth
Oct 17, 2005 - Chinese astronauts Fei Junlong and Nie Haisheng landed safely in Mongolia on Sunday, after spending 5 days in orbit. Their Shenzhou-6 capsule touched down by parachute less than a kilometre from their target, and were met by helicopters and off-road vehicles. Fei and Nie will spend the next 14 days in isolation, to observe their post flight health; however, their families will be able to visit. The Chinese Space Administration has hinted that spacewalks and women astronauts will be in future missions. (Full Story)

Mid-Latitude Glaciers on Mars
Oct 17, 2005 - New high-resolution images of Mars have revealed several glaciers in the planet's mid-latitudes, far away from its polar ice caps. Scientists had speculated that many of Mars' mid-latitude features looked like they had been formed by shifting ice, but there wasn't any sign of the actual glaciers. New images from Mars Odyssey show features, such as debris lines on valley floor, which are amazingly similar to Earth glaciers. (Full Story)

Matter Swirling into a Supermassive Black Hole
Oct 17, 2005 - Near-infrared images of galaxy NGC 1097 show incredible detail of the filamentary structure of matter swirling down to the supermassive black hole lurking at its centre. NGC 1097 is located about 45 million light-years away in the southern constellation Fornax. Astronomers used a special instrument on the European Southern Observatory's Very Large Telescope which masks the light from stars in the galaxy, revealing fainter material. The way this material winds as it nears the centre of the galaxy indicates the mass of the supermassive black hole. (Full Story)
