In one of those science puzzles the general public has generally been sheltered, for whatever reason, the consensus has admitted problems did exist with moving spacecraft about by using gravity of big planets such as Jupiter to provide a boost. In the event, they claim they have solved the puzzle. It couldn't have been much of a problem as spacecraft were regularly boosted by the so called 'sling shot' method, and NASA has been very successful.
Stonehenge is going back further into the past according to www.bbc.co.uk/news/uk-england-wiltshire-24488759 ... or rather, a Mesolithic site on a hill overlooking Stonehenge is proving to be an archaeological tree ring of time. The site, closer to Amesbury than Stonehenge, and ignored by archaeologists for years, will in all likelihood go back in time to 10,000BC, or there abouts. They have dug out a trench and found a boar's tusk that gave a date of 7596BC - but they are not at the bottom of the trench as yet. There is still a way to go.
In 1251 lightning is said to have destroyed the bedchamber of the queen at Windsor and shook the whole house. In the nearby Windsor Forest thirty five trees were split asunder (Matthew Paris, Historia Anglorum). Lightning struck this year too, striking houses and setting them abaze (Weather Eye, The Times). For example, in Wakefield lightning hit a chimney, passed into the loft and then travelled through the central heating system and set the house on fire.
The boundary event is the same as in yesterday's post, the transition from the Palaeocene to the Eocene, but the date is slightly different - 56 million years ago rather than 55 million years ago (but what's a million years in uniformitarian geochronology - a sliver of time equivalent to the thickness of a cat's whisker).
At http://heritageofjapan.wordpress.com/2013/10/08/6thearly-8th-century-yok... ... is about Late Kofun burial catacombs of the 6th to 8th centuries AD, some of which have lovely murals. They are thought to be the last resting place of individuals from a Japanese warrior society. However, a few of the images have the back drop of spirals and ring or maze like motifs, more commonly found in European rock art. The blog author then seeks an origin for the catacombs in East and Central Asia - even as far away as northern India.
At http://phys.org/print300440386.html ... this story has the title, 'first ever evidence of a comet striking the Earth' - and the event is dated 28 million years ago, leaving evidence behind in the Sahara desert. We may note the date safely shifts the event away from human memory - unlike the less popular idea that something similar happened at the Younger Dryas Boundary, a mere 13,000 years ago.

No surprise that people were watching the sky in Arizona as they were elsewhere in the world - and built structures to predict the return of worrisome space rocks, including meteorites. Two 12th century settlements in the dry lands of Arizona, set one hundred miles apart, have one thing in common - meteorite shrines. Archaeoastronomy is the study of ancient cultures and how they tracked celestial events.
At http://phys.org/print299786071.html ... a new study by climate scientists at the University of Berne in Switzerland has been looking at the Little Ice Age. In classic terms this is a tale of two halves - divided by a reprieve during the 16th century (the Tudor Period) when grown up men wore pantie hose - right up to their bloomers. In contrast, it must have been cold in the 17th century as grown up men wore thick trousers and long coats and balanced tall hats on their heads.
At www.thelocal.se/50604/20131004/ ... archaeologists in northern Sweden have come across the remains of farm dating from around 1100 BC, in a completely unexpected location. Is this evidence of people migrating long distances in the aftermath of cosmic catastrophe? It dates just after the end of Late Bronze Age. Presumably the farm was not viable after 800BC when a colder climate system kicked in.
At http://phys.org/print300352509.html ... a core sample from New Jersey geology, in a region once beneath the sea (55 million years ago) has clay bands around 2cm thick that appear to have been laid down rhythmically, or cyclic. As such, they were akin to tree rings, providing an annual pulse, a yearly amount laid down as strata. I've heard similar wave patterns in sediments described as Milankovitch periods but annual changes preserved in the geological record doesn't appear to comply with uniformitarian geochronological parameters.
