The 300/200BC event

We now have the 300/200BC event (see ... Dallas Abbot, a geologist based at Columbia University in New York, says an asteroid 183m wide crashed off the coast of New Jersey and sent a tsunami surging across what is now New York city over 2000 years ago.

Hazards from Space .... including a relook at the Tunguska event

At we learn that the Panoramic Survey Telescope has discovered an asteroid that will come within 4 million miles of the Earth in mid-October (a couple of weeks to go). It's a bit early for 2012 predictions and the object is just 150 feet in diameter. It will not strike the Earth, we are informed - and just as well, but scientists suspect there are many more of them under a mile across that have not yet been discovered - and you never know.

Comets and the Bronze Age collapse

George Howard, at September 26th ... has posted an article by Bob Kobres that acknowledges it is based on an artilce published by SIS in C&C Workshop 1992:1. This version has some additional images. One interesting point made by Kobres comes from Martin Brennan's The Stars and the Stones (Thames and Hudson: 1984) (reviewed by SIS a number of years ago) and concerns Tara, a ritual complex of the gods 10 SW of Newgrange.

The Trojan War

It seems that some European scholars have recognised there might be a connection between a comet or meteor and the end of the Late Bronze Age which in turn sparked an earthquake storm across the plate boundaries from the Aegean and Anatolia to at least as far east as Pakistan and India. Two articles in a book, Science and Technology in Homeric Epics (2008) are relevant. One is by Amanda Laouipi and the other by SP Papamarinopondas.

... yes, there are nano diamonds at the YD boundary event, preserved in ice on Greenland.

This is a paper by Kurbatov, Mayewski, Steffensen, West, the Kennetts, Bunch, and others which can be downloaded free in full text from August 31st. Recommended reading. Basically, a small layer of free nanodiamonds in very high abundances implies an unprecedented influx of extraterrestrial material  that occurred over the last glacial episode. From that layer nanodiamonds and hexagonal diamonds (lonsdaleite) of the order of many times grreater than background levels in adjacent younger and older ice.

No nano diamonds at YD boundary ....

Embedded resistance to the YD boundary event is evident in the post at (see also ), a report on a paper published in the August 30th issue of the Proceedings of the National Academy of Science by Tyrone Daulton, Pinter and Scott et al. They say they could find no evidence of nanodiamonds in YD boundary material - and this means the impact hypothesis has lost it's sparkle.

YD event update

Bill Napier reports that a Canadian radar meteor team has confirmed and modelled the predominance of Comet Enck/progenitor in the Zodiacal Cloud (a catastrophist model). At this moment in time the thesis goes unchallenged in astronomical circles. Nobody has produced a viable objection to date as yet. A meteoroid storm, he asserts, is a plausible scenario. He continues by saying he would like the progenitor to be some 100,000 years of age (in the solar system) which is in line with Fred Whipple. However, David Asher and Duncan Steel see it as somewhat younger.

Coal through the microscope

Go to where it says microscopes reveal the hidden nature of coal - made from thick accumulations of plant debris, mixed with swamp sediments. Also, coal contains a lot of charcoal - as a result of fires raging through the landscape as the coal was being formed. Now, that is catastrophic.

Near Earth Objects

At is a short post with a video clip of the asteroids that fly close to the earth - and only those discovered by telescope. It excludes the additional near earth objects found by the WISE mission. It was compiled by astronomer Scott Manley over the last 30 years. He is a former research student at Armagh Observatory.

A new paper on nanodiamonds at the YD boundary

At we have news of a new paper due to be published by the Journal of Glaciology by Kurbatov, Mayewski and Steffensen et al which presents evidence for a prominent peak in nanodiamonds in a narrow layer of ice in Greenland ice cores that date just prior to the YD boundary event. A direct link to the article will be available in due course.
