Halley's Comet

One from William. Why Halley's Comet may be linked to famine 1500 years ago. Sounds almost like Patrick McCafferty and Mike Baillie in their book, 'The Celtic Gods' - but it comes from Dallas Abbott. Did a piece of the comet slam into the Earth in AD536? This is already attributed to two volcanoes - now conceded by Baillie. However, Abbott approaches it slightly differently - and combines volcanoes with impact (did one spark the other?) The theory evolved after Abbott was looking at Greenland ice cores laid down between 533 and 540.

Geothermal Greenland

Pierre Gosselin provides a guest post by Kenneth Richards which has some interesting information - especially if you've visited hot springs in Canada, a very cold part of the world. Well, Greenland is a lot colder than most of Canada and it too has geothermal hot springs - right under the glaciated region.

Revising solar system history

Sent in by Robert - go to https://www.nature.com/articles/d41586-018-01074-6 ... which questions the idea of the Late Heavy Bombardment, a theory which has had a somewhat extended life. The bombardment is thought to have occurred half a billion years after our planet was formed. In the process all hell was let loose as a barrage of asteroids remodeled the surface of the Earth. Only after this stream of space debris had quietened down was Life able to evolve. However, it seems mounting evidence has caused a body of researchers to question the hypothesis.

More on Keros 2

At https://phys.org/print436032776.html ... sent in by William. Dhaskalios, a nearby island but once a promontory of Keros, was at one time almost completely covered in monumental structures of gleaming white marble. Another slant on the same story as in an earlier post.

Windy Black Holes

This story is at https://phys.org/print435824324.html ... new research shows evidence of strong winds around black holes - throughout the bright outburst events. This is the point where black holes are thought to be feeding - rapidly gorging on material that has been dragged into their vicinity. This, in turn, is said to show how mass transfers to black holes and how black holes can affect the environment around themselves. The winds are hypothesized to blow away matter the black hole cannot consume.

Dust Storms Mars

At https://phys.org/print435918054.html ... it seems like all the juicy research turns up months after space missions - and so it is with Mars. A study published in Nature Astronomy used data from NASAs Mars Reconnaissance Orbiter and suggests dust storms on Mars have a direct link with gases escaping from the top of the atmosphere. The inference is that a wetter warmer ancient Mars lost its liquid volatiles by the same route - launched out of the atmosphere.

Velikovsky Comet

Velikovsky perceived his Exodus comet as raining hydrocarbons on the Earth - among other things less salubrious. We now know meteorites contain hydrocarbons - and so do comets. Planet sized comets are not necessary - just your run of the mill comet such as Comet Churiyumov Gerasimenko (visited by the Rosetta Mission). At https://phys.org/print435919207.html ... we learn that instruments aboard the space probe Rosetta analysed dust particles ejected from the comet's nucleus. This research was published by the Royal Astronomical Society in December of 2017.

Cosmic and Comet Dust

Is the origin of Life just cosmic dust in the wind? Carl Sagan famously siad 'we are made of star stuff ...' and perhaps we are. See https://phys.org/print435920203.html ... A new study proposes Life on Earth started from particles flyings as dust from outer space. As such, a 105kg of space dust reaches Earth every day - apparently. More interestingly, small particles in the earth's atmosphere could be picked up by the these streams of space dust and transported across the universe to seed far away planets.

oxydised iron

Diamonds with garnets can form at depths within Earth's Manetle. Earth scientists, it is said, made a discovery that 550km beneath the surface - oxydised iron. This is similar tro rust. It was found within garnets within diamonds - we are told. How does iron become rusty within the Mantle? One might point a finger at water in the Mantle - but not these guys. We know that iron exists as a metal in the core and Mantle - or so the mainstream songsheet assures us (and why not - a reasonable deduction).

More on Keros

The full article by Colin Renfrew (which doesn't include the recent discovery of drainage channels under the surface) is available at https://www.britac.ac.uk/sites/default/files/JBA-001-187-Renfrew-HR.pdf ... see also DOI:10.5871/jba/001.187 ,Journal of British Archaeology' 17th December 2013 (as published in the same journal pages 187-2120. You can also watch a video of the discoveries on Keros at https://www.youtube.com/watch?v=hYlaQn7LUjM ... Renfrew is mostly concerned with the sanctuary in this paper which dates to the end of the mid 3rd millennium BC.
