Rosetta getting bashed

At ... the Rosetta saga continues - it has now experienced significant buffeting and difficulties over controls as Rosetta swoops low across comet Churyumov-Gerasimenko, so much so that such close encounters may have to be curtailed in the future. It encountered a dense outflow of gases and dust particles that temporary caused scientists on earth to lose control of the spaceship.

Southern Lights

  at ... a nice image of the Southern Lights - aurorae near the South Pole. These have recently been visible from Australia but are apparently a rare occurrence as far north as Brisbane - more usually restricted to Tasmania.

wetland Utah

At .... some really cracking stone tools can be seen at this link, including a spear head known as a Hackett Point, dating back 12,000 to 13,000 years ago. This appears to be a misprint or mistake as they are referring to a time prior to the Younger Dryas event, which occurred around 12,900 years ago. Perhaps it should read BC rather than 'years ago' -  or some anomaly has crept into the text.

Why Egypt Fell

The link below is to a video of a programme on Discovery Channel some time ago. It relates the story of archaeologists seeking to understand why the Old Kingdom fell - and why eighty per cent of villages in the delta ceased to exist (suddenly and dramatically). Of course, if you look at the event from a terrestrial point of view you will reach a terrestrialised answer. In the case of the film makers the Old Kingdom of Egypt and the Akkadian Empire in what is now Iraq, fell as a result of drought.

dreaming of the big wave on Mars

At .... as it has been repeated now on many occasions the assumption is growing strength in the idea that Mars once harboured an ocean - suitably way back in the early universe. Once you come to accept there was once plentiful supply of water on the red planet, and a big ocean, you can conjure up almost anything - especially if you create a model.

new C14 technique

At .... we are informed archaeologists will be able to get dating results quicker and cheaper which will be a massive boon. At the moment c14 dating is so expensive only a few sample are ever properly dated - unless the archaeology budget has big money as a back-up. The new technique can also be used on site - without being sent to a laboratory (and having to wait for weeks to get the reply).

lava tubes on the moon

Another interesting post from .... no, not a reference to cities already on the moon, hiding in cavities and lava tubes, but the prospect of earthlings colonising the moon and finding somewhere safe to set up camp. Speculation is that theoretically lava tubes could exist on the moon over half a mile in width, big enough to harbour a lunar colony. They are pictured as offering a refuge from cosmic radiation, meteors, and temperature fluctuations. Sounds quite reasonable when you digest the whole story.

circles, ancient texts, and fortifications

At ... strange ritual sites in NW China (spilling over into Mongolia) appear to go back to 2500BC - the same age as Egypt's pyramids and Stonehenge in the UK.


At ... we have all heard of Tiahuanaco, high in the Andes, and its mysterious ruins - now a buried pyramid is thought to have been discovered.
