Comet Churyumov-Gerasimenko

You'll get used to the Russian name of this comet as it approaches Mars in October. According to the European Space Agency (ESA) the comet is losing the equivalent of two tumblers of water per second - which is a lot of water vapour (go to

Greenhouse Venus

There is a discussion ongoing at ... and one commenter has come on and said Venus was born from Jupiter just 6000 years ago. What is the modern view of Carl Sagan's greenhouse Venus - go to link above and join in if you like.

Kurgans in Georgia

At .... in Georgia in the South Caucasus, a chariot burial has been dug up from beneath a kurgan (burial mound). It dates back to the Early Bronze Age, or the second half of the 3rd millennium BC, and there were, in fact, two chariots each with four wooden wheels. Various artefacts were found, even though the tomb was robbed in antiquity.

New fangled computer modelling and science

Apparently, the BBC have recently issued a response to a complaint by the Green lobby, complaining about an interview in which Lord Lawson allegedly led listeners astray. This is all part of the campaign to silence dissent on CAGW - as so much money is riding on the scam and it must continue if wallets are not to be depleted. The complaint appears to be that Lawson was unqualified to speak on the climate - even though he had written a best selling book on the subject.

Slowing the Speed of Light

At ... physicist James Fransen of the University of Maryland has a paper in New Journal of Physics in which he claims he has found evidence the speed of light as described in Einstein's Theory of General Relativity, is actually slower than thought. His argument actually rests on observations of a supernova event from 1987 - and how long it took photons to arrive. They turned up later than expected.

Space Weather

At ... the site is updated daily and is  always worth a brief snatch of your attention. Today it has a video of sprites in the sky above Oklahoma on June 23rd. One of themis 40 miles tall and 46 miles wide - hardly a sprite in the literal meaning of the word. It was bigger than Mount Everest.

Sprites have been recorded over a long period of time but scientists did not believe they existed and ignored them until after 1989 when they were photographed from the space shuttle. Basically, sprites are upward rising lightning bolts

Sand dunes in Antarctica

Earth and Planetary Science Letters 209 (2010) page 30-42 is an article on the age and migration of dunes in Antarctica - they are thought to have been caused by sublimation

Skyscape Archaeology

Following on from yesterday, this story can also be seen at --- and comes with some nice images. Stone chambered tombs in the northern part of the Cotswolds appear to be astronomically orientated while on Bodmin Moor in Cornwall the three stone circles known as the Hurlers are reputed to be based on the three stars in the Belt of Orion. Further information is available at - the web site of the Royal Astronomical Society.

Titan again, and coronal rain

At ... anomalous amounts of nitrogen detected in the atmosphere of Titan have caused some scientists to have a rethink. Does it indicate Titan's raw materials might have been locked up in ices that condensed before Saturn was formed? The study, a collaboration between NASA and ESA, says they have found 'firm' evidence nitrogen on Titan originated in conditions similar to those of comets (assumed to have an origin in the Oort Cloud on the outer rim of the solar system).

Dr Daniel Brown, Fabia Silvia.

Dr Daniel Brown of Nottingham Trent University is intending to bring archaeo-astronomy out from the shadows of the controversies engendered by Alexander Thom and an establishment unprepared for the fact that Neolithic people were not quite as rustic or backward as the orthodox consensus allowed in the late 20th century. A new generation of archaeologists are not quite the stuffed shirts of old and hence, archaeo-astronomy, at last, is getting a dust down and coming out of the closet, where it was swept away all those years ago, in the flower of our youth.
