Gravitational Vortex

At ... the ESAs orbiting X-ray observatory has 'proved' the existence of a 'gravitational vortex' around a black hole. The study, which included NASA data from the NuSTAR mission, has solved a 30 year mystery we are told. The theory is that as matter falls into a black hole it heats up as it plunges into doom, swallowed by the black hole. At that point of very high temperature it shines x-rays into space.

Philistine graves

At ... a Philistine cemetery has been found at Ashkelon, a Mediterranean port city in the Bronze and Iron Ages. Some 150 burials are said to date from the 11th to the 8th centuries BC. The good news is that bone samples will be analysed - for DNA, radiocarbon dating, and other biological reasons. Ashkelon was situated just to the north of Gaza, a trading hub that was used by the Egyptians to sell and transport slaves, linen, and other manufactures such as papyrus.

Space Weather

At (July 10th) we hear that Earth is currently insdie a single speed stream of solar wind flowing from an enormous hole in the atmosphere of the sun.

Ordovician co2 problem

At .... we are told that during the Ordovician period the amount of co2 in the atmosphere was eight times greater than in the modern world. Why then did climate not develop into runaway global warming? The Ordovician period is normally associated with glaciation.

Leaking Atmosphere

At ... the magnetosphere shields earth from the solar wind (or plasma injections) but at Earth's poles the field lines are open - like those of a bar magnet. Hence the solar wind is able to descend towards the earth's surface. However, just as particles can head downwards so too can particles ascend upwards - ions from the earth's atmosphere (the ionosphere). The question of plasma transport and atmospheric loss is relevant not just to planets we may note but to stars also.


Formerly known as Gla but apparently now Glas we have an article in the journal Popular Archaeology - see ... where the site of Glas has recently been reassessed by archaeologists (with more up to date instruments). Glas is the largest Mycenaean site from Bronze Age Greece. It is located in what was known as Boeotia in the marshland of the Kopais Basin. Glas was ten times the size of Tiryns and seven times the size of Mycenae.

Clovis First under pressure

Give a day or two and they will give a bit. At ... and I thought for a moment she was an archaeologist. It seems we have somebody not very keen on 'authority' or being told aboriginal history (in Canada) which is contradictory to tribal tradition. She is kicking at the wall that is Clovis First - and good luck. Can't say I have much sympathy for the Clovis First proponents but arguing from emotion doesn't appear to be too effective. So far.

Closing In

Closing in is the term used in the link at ... but is it just too hopeful? Closing in on black holes, a theory now within an arms length of actual observation.
