Seven Sisters secrets to be uncovered before cliffs tumble into the sea

The secrets of the cliffs at Seven Sisters are set to be uncovered by archaeologists who believe the site could be on the of UK’s most important prehistoric monuments. 

The hilltop enclosure at Belle Tout is an ‘archaeological mystery’ – according to the National Trust, whose archaeologists will be starting a dig next month (September) to uncover the secrets before the cliffs erode into the sea. 

They hope to find evidence of an early Bronze Age settlement. It is already known that there is a huge outer earthwork, 1.2km long, but archaeologists have yet to arrive at a date for when the hilltop enclosure was built. Previous finds are from different eras including prehistoric flintwork and early Bronze Age Beaker pottery.

What sets this project apart from previous excavations is the application of new scientific techniques such as LiDAR laser scanning, environmental sampling, Optical Stimulated Luminescence (which measures the last time an object was exposed to light) and even analysing microscopic snails, which only exist in certain habitats and give clues as to the ancient landscape. Read more.

The Transit of Venus

The transit of Venus across the Sun takes place when the planet Venus passes directly between the Sun and a Earth. This last occurred in early June of 2012 and lasted about 6 and a half hours. The transits of Venus are incredibly rare and occur in a pattern that generally repeats every 243 years.

Seven Sisters: Pleiades

The Seven Sisters, also called the Pleiades or M45, is an open star cluster located about 400 light years away towards the constellation Taurus. It is about 13 light years across and is one of the brightest and closest star clusters to us.

The cluster contains over 3000 stars, most of which are considered middle aged. Surrounding the brighter stars are reflection nebulae, gas and dust reflecting the light from the stars. Also buried in the cluster are faint, low mass brown dwarf stars.
