Eclipses at the Double!
Sometimes the bodies of the Solar System line up to provide denizens on Earth with a spectacular show. The lucky inhabitants having a grandstand view of the total lunar eclipse due on 8 October will watch our Moon turn spectacular autumnal shades of golden coppery-reddish-brown. Just a couple of weeks later, a partial solar eclipse will occur but this will only be visible from eastern Siberia, Alaska, Canada, most of North America and all of Mexico except for the Yucatán Peninsula. If you're in these areas and want to witness either of these syzygy1 events, consultation of local times is advised.
A Martian Close Shave
On 19 October, Comet Siding Spring (C/2013 A1) will scoot past Mars. Up till 2013 scientists thought the comet was going to impact Mars' surface, but now it is projected to miss the planet by 132,000km. This is approximately a third of the distance from the Earth to the Moon, and what astronomers deem a close shave, or near miss. NASA have published an artistic image of what a tall Martian would see.
Halley's Celestial Fireworks
The Earth will pass through remnants of Halley's Comet's many visits to the inner Solar System between 2 October and 7 November. Any cosmic dust which hits Earth's atmosphere will cause the particles to glow. People lucky enough to witness this spectacle will no doubt be wishing upon the 'shooting stars'. Appearing to emanate from the constellation Orion 'the Hunter', this meteor shower is known as 'the Orionids'.

The IAU (International Astronomical Union) are now accepting nominations to name extrasolar planets. If you wish to call one 'Bob' after your uncle, then you'll need to read these instructions carefully. Please let me know if you apply, and what the result was!
