Flares on Brown Dwarf

At https://phys.org/print447490481.html ... astronomers have spotted two super flares issuing forth from a brown dwarf star. The discovery is detailed in a paper published on May 26th on the arXiv pre-print server. The flares had a duration of around two days and heightened by a factor of 48.

Origin of Pluto

It is being suggested Pluto is a great comet - of sorts. They say it is an agglomeration of a billion comets (in other words an inestimable number of comets). Another idea is that Pluto formed from coldices with a chemical composition similar to the Sun (but the giant comet theory is gaining traction it is alleged).

0.02 of human induced global warming

Having a laugh. The amount of co2 emissions perpetrated by humans is falling every day it would seem. Dr Boris Smirnov, an atomic physicist and author of textbooks on the subject, has eitten a scientific paper on co2 emissions, calculating the effect of atmospheric co2 during the radiative transfer process (a big part of global warming theory). He claims this idea is flawed - and new calculations reveal the climate's sensitivity to a doubling oc co2 concentration is just 0.4 and the humna contribution to that figure is a negligible 0.02K. This virtually nothing at all.

K/T boundary event

Sent in by Jovan (as the earlier link to Sky and Telescope). Global warming caused by co2 levels reaching 2300 parts per million. Currently we have just over 400 parts per million and alarmists are feeling very wobbly. WEhat researchers have found is that after the K/T boundary event temperatures shot up - in North Africa. One might suppose an asteroid strike would cause global cooling due to lots debris in the atmosphere - and the researchers acknowledge this. They claim it was followed by a period of global warming which lasted for 100,000 years.

Near Miss

At www.skyandtelescope.com/astronomy-news/close-stellar-encounters-surge/#.... ... close stellar encounters. An analysis of our stellar neighbourhood is said to reveal more stellar traffic then recognised - stars that sideswipe our solar system. That potentially hurl hailstorms of comets inward and showering our planet with debris. Not just worlds in collision but stars and solar systems in collision.

Iran archaeology

In Current World Archaeology 89 (June 2018) - www.world-archaeology.com ... there is an article on Iran's prehistory. It says the archaeology of Iran is dominated by the Zagros mountain chain which divides it from the flood plain of the Tigris and Euphrates. To the west of the Zagros are the fertile lands of Mesopotamia and to the east the hilly upland of the Iranian plateau (rich in metals but also fertile in places). The Neolithic revolution, we are informed, began in the hills and valleys of the Zagros between 10,000 and 8,000BC.

Further on Stonehenge Landscape

Further updates on the Stonehenge landscape are outlined in Mike Haigh's 'archaeology review' in Northern Earth magazine 153 (June 2018) - see www.northernearth.co.uk ... It seems a causewayed enclosure has been found at Larkhill barracks during an archaeological survey prior to construction of new buildings - and the excavation is ongoing. Causewayed enclosures are usually concentric circles with sausage shaped ditches (or pits) with banks. A henge is a circle with a continuous ditch and bank.

Stonehenge Landscape Research

British Archaeology magazine (May of 2018) has an interesting article by Mike Pitts. It concerns geophysics surveys around Stonehenge. The Hidden Landscape project and the First Monuments project are quite well known but there has been a lot more archaeology that does not reach the mainstream media but is done by local groups and most importantly, prior to development. In this case there are new housing schemes in the vicinity of Amesbury and a huge commercial park to the east of Stonehenge.

Electric Dark Matter

At https://phys.org/print446911328.html ... Does dark matter carry an electric charge is the headline - which turns out to be a bit of PR. Astronomers, it is said, have produced a new model for the invisible matter that is supposed to make up most of the universe - the so called dark matter (unseen and unverified). These particular astronomers and modellers think dark matter might have an electric charge. However, this is just a 'tiny' electric charge - so they are not jumping in with both feet.

Grand Canyon Geology

At https://phys.org/print447061881.html ... it is 50 years since the last formation was discovered and defined in the Grand Canyon but now geologists have been having a look at the Sixty Mile Formation - and their research is published in Nature Geoscience. It seems this particular piece of the Grand Canyon is somewhat younger than thought - ie it was generally labelled PreCambrian. The Sauk marine transgression event is dated between 600 and 500 million years ago and the formation is somewhat older.
