A Life on Mars. Talk by Bud Martin

25 NovHerschel Museum of Astronomy

A Life On Mars by Bud Martin We take a look at the personalities, speculations and theories that have contributed to our changing views of the Red Planet over the last 150 years. From the sublime to the ridiculous, we examine what it takes to visit our near neighbour. About Bud Bud first became interested in astronomy at 8 years old after seeing a bright meteor flash across the night sky. Determined to learn more, he avidly read all the astronomy books in the local Public Library then set about making his first telescope from spectacle lenses and cardboard tubes. At the same time, he developed a love for music and by the age of 13 had made his own electric guitar. Nearly 60 years later, Bud is still performing at gigs on his equally old Gibson 345. Astigmatism in his right (dominant) eye began to make observation at the telescope eyepiece a troublesome experience so Bud developed a system using a modified web-cam to view the heavens. Naturally, this paved the way to enable him to capture the images he was seeing on the computer screen. Constantly improving camera sensor technology meant that before long he was seeing objects – especially on the Lunar surface – in such detail impossible with his naked eye. Bud is an internationally published Lunar Astrophotographer. The event: Bath Astronomers monthly meeting for all members and new comers to meet up, enjoy perhaps a new topic and a cup of tea and a biscuit. Held on the last Wednesday of every month at the Herschel Museum of Astronomy, 19 New King Street. Bath Astronomers' members and under 18s enter for free. All visitors welcome and there is an entry charge of £5. Reduced to £2 for Herschel Society members and students. Picture: Bud Martin

A Path North

Mario Konang

What happens if you keep going north? The direction north on the Earth, the place on your horizon below the northern spin pole of the Earth -- around which other stars appear to slowly swirl, will remain the same. This spin-pole-of-the-north will never move from its fixed location on the sky -- night or day -- and its height will always match your latitude. The further north you go, the higher the north spin pole will appear. Eventually, if you can reach the Earth's North Pole, the stars will circle a point directly over your head. Pictured, a four-hour long stack of images shows stars trailing in circles around this north celestial pole. The bright star near the north celestial pole is Polaris, known as the North Star. The bright path was created by the astrophotographer's headlamp as he zigzagged up a hill just over a week ago in Lower Saxony, Germany. The astrophotographer can be seen, at times, in shadow. Actually, the Earth has two spin poles -- and much the same would happen if you started below the Earth's equator and went south.
