The Malvern Zodiac

Malvern Zodiac

According to its discoverer, Alan Gripton, the Malvern Zodiac is the oldest constellational star map in the world

“At the heart of England where ancient counties meet, a beautiful terrestrial zodiac lies hidden – the Malvern Zodiac – a circle of ancient constellations carved into the landscape by the first post-glacial inhabitants of this land more than 10,000 years ago.It is obscured from the modern world by its enormous size and most of the surviving graphic outlines now form the roads, footpaths, waterways and field boundaries of a 21st century agricultural landscape.

The Malvern Zodiac is the source of legends – a unique design that preceded the zodiac that we all know today. It opens a window into the dark and distant past of our ancestors and, when compared to historical documents, holds ramifications that will send shockwaves through the dusty corridors of church and academia.”

The Square Kilometre Array

Square Kilometre Array layout

The Square Kilometre Array will be the world’s largest telescope with thousands of dishes in Australia and South Africa connected by fibre optic cables that will require capacity greater than the total internet traffic of the world.

The antennas will be arranged in five spiral arms extending to distances of at least 3 000 km from the centre of the array.

The spiral layout has been chosen as this gives many different distances (baselines) and angles between antennas resulting in very high resolution imaging capability. The perfect layout would be a random arrangement that maximises the number of different baselines and angles between antennas. However the practicalities of construction, as well as linking the antennas together with cables, mean that the spiral configuration is the best trade off between image resolution and cost.

It will be able to survey the sky 10000 times faster than before.

The project is due to commence in 2016 for completion in 2024
