I am delighted to launch our new quarterly email newsletter. It is aimed at the general public with an interest in science and especially in my life-time passion – everything related to the sometimes contentious concept that LIFE IS A COSMIC PHENOMENON.
Last year we created a base paper summarizing the Panspemia Hypothesis in 2013.
This newsletter will build upon this foundation, exploring increasing evidence for Panspermia as astrobiology starts to play a dominant role in most experiments underway and planned by NASA, the ESA, and by the Space Programs of China, India and Japan.
Feedback is appreciated. Please feel free to contact me :

May 26, 2014 : Professor Chandra Wickramasinghe is appointed as Visiting Professor of the InRC (International Research Centre) at University of Peradeniya, SRI LANKA.
The Senate approved his appointment in its 390th meeting as InRC affiliate visiting scholar for a period of one year commencing from 01/07/2014.
I delivered a lecture entitled “New evidence for life as a cosmic phenomenon” at the Astronomical Society of Oman in Muscat on 15th January 2014, at the University of Peradeniya, Sri Lanka on 23rd January. The audience at Peradeniya included Professor Rohana Chandrajith, Professor of Geology, who had been reported as being antagonistic to the idea that the Polonnaruwa (Aralaganwila) stones that fell on 29th December 2012 were indeed meteorites1. In a discussion that followed the lecture Professor Chandrajith agreed that the Polonnaruwa stones in question did not resemble any that can be found anywhere locally. He further confirmed that his earlier reservations were based on the fact that these stones were different structurally and compositionally from any of the known and documented classes of meteorites. He alo agreed that there is no possibility that these could be fragments of industrial slag as was proposed by some critics.
The most recent studies of the Aralaganwila stones by Jamie Wallis et al2,3 that show oxygen isotope compositions inconsistent with Earth material, as well as extraordinarily high amounts of the terrestrially rare chemical element iridium strengthens the case for the Polonnaruwa stones being meteorites, and if so they contain unequivocal evidence of the existence of extraterrestrial microbial life. This discovery would then transform the way we think about the Earth and of life upon it as radically and profoundly as did the Copernican revolution some 500 years ago.
The view that the Polonnaruwa meteorites represent fragments of loosely held siliceous grain material within a cometary bolide from which water and volatiles were boiled off upon entry, thus leaving a highly porous structure, remains the most plausible explanation of all the available facts. A provisional identification with meteoroids in the annual Taurid meteor stream4 which we originally made is interesting particularly in view of the fact that the large bolide which led to the Tunguska event of 1908 did not lead to the recovery of any large meteorite fragments.
On 24th January 2014 I had an audience with His Excellency President Mahinda Rajapakse, President of the Democratic Republic of Sri Lanka. I appraised the President of the latest findings regarding the Aralaganwila meteorite and urged His Excellency to declare the location of the 29th December 2012 meteorite fall as a site of national scientific heritage. In the fullness of time the events of this day that took place in Sri Lanka would be regarded as having established beyond doubt that life is a truly cosmic phenomenon. President Rajapakse gave assent to this proposal without reservation and immediately set in train the protocol that would ensure its implementation
9 Feb 2014 :
Twelve months ago, publication of the 29 Dec 2012 POLONNARUWA METEORITE preliminary analysis resulted in a global furor. The rapid release of the first (of five) academic papers triggered criticism of the paper’s scientific analysis methods . The first paper was criticized by some who argued the contamination question had not been sufficiently addressed. Some even questioned whether the rock would be accepted as a meteorite by the British and International bodies.
Over the next four months, four more in depth academic papers reported the detailed analysis which provided evidence for the early claims. A later paper in December 2013 from Dr. Jamie Wallis looked at the rocks as geological objects. His paper is being used to register the rock as a proven meteorite with the British and Irish Meteorite Society and then the International Meteoritic Society.
8 Dec 2013 (Peak of Taurid Shower): The ANURADHAPURA METEORITE
A second incident happened in Sri Lanka just 2 months ago – just twelve months after the POLONNARUWA METEORITE. This second meteorite incident is now known as the ANURADHAPURA meteorite fall. This was witnessed on 8 Dec 2013 at the peak of the Taurid Shower – Taurid’s are the debris of Encke’s comet.
The Anuradhapura meteorites, were examined at Sri Lanka Institute of Nanotechnology (SLINTEC) who specialize in Nanotechnology research. Equipment used included a Hitachi SU6600 Analytical Variable Pressure FE-SEM. Hitachi SU 6600 is a versatile SEM allowing observation of a wide range of materials at high resolution. The following image shows SLINTEC and a sample of the structures that were found, many being deeply interwoven and intertwined into the rock matrix, evidence consistent with the position that they are not contaminants. Note that the Anuradhapura meteorites (like the Polonnaruwa meteorites) do not resemble any terrestrial stone that could have lain anywhere near the recovery location.
