Polonnaruwa – Hard evidence of panspermia, or bad science?

Sounds exciting, but we’re skeptical so far.

A meteorite that Landed recently, close to the ancient city of Polonnaruwa in Sri Lanka has been described as the most important scientific discovery in the last 500 years as it carried “compelling evidence of life” from outer space.

The scientists who discovered the contents of the meteorite said, “we report here the first compelling evidence for life existing outside the earth.’

Following extensive lab work in the United Kingdom and Sri Lanka four scientists in a paper said , “We report the discovery for the first time of fossilized diatoms in a carbonaceous meteorite that fell on 29 December 2012”. Diatoms are a variety of algae.

They very firmly said contamination, a hazard scientists face when examining things fallen from the sky on the ground is excluded in the meteorite they have named Polonnaruwa.

We’ll keep looking out for follow-up on this and further support by the scientists, one of whom is Nalin Chandra Wickramasinghe, the only scientist testifying for the defense of creationism and against evolution at the scientific/creationist trial in Arkansas.

It Came from Outer Space: “Comets Brought Building Blocks of Life to Earth”

Could life on Earth as we know it have come from outer space? New research from Lawrence Livermore National Laboratory scientists shows that comets that crashed into Earth millions of years ago could have produced amino acids – the building blocks of life. Amino acids are critical to life and serve as the building blocks of proteins, which are linear chains of amino acids.

“There’s a possibility that the production or delivery of prebiotic molecules came from extraterrestrial sources,” Goldman said. “On early Earth, we know that there was a heavy bombardment of comets and asteroids delivering up to several orders of magnitude greater mass of organics than what likely was already here.

Livermore’s Nir Goldman and colleagues found that simple molecules found within comets (such as water, ammonia, methylene and carbon dioxide) just might have been instigators of life on Earth as the sudden compression and heating of cometary ices crashing into the planet can produce complexes resembling the amino acid, glycine.

Origins of life research initially focused on the production of amino acids from organic materials already present on the planet. Further research showed that Earth’s atmospheric conditions consisted mainly of carbon dioxide, nitrogen and water. Shock-heating experiments and calculations eventually proved that synthesis of organic molecules necessary for amino acid production will not occur in this type of environment.”

Ancient Organic Particles from Space Discovered in Antarctica

A new family of extraterrestrial particles, probably of cometary origin, were discovered this spring by researchers from the Center for Nuclear Spectrometry and Mass Spectrometry (CSNSM) in central Antarctica. The micrometeorites, which are remarkably well preserved, are made up of organic matter containing small assemblages of minerals from the coldest and most remote regions of the Solar System. The team discovered two micrometeorites measuring no more than .003 inches and .01 inches across, “exhibiting a fine-grained, fluffy texture with no evidence for substantial heating during atmospheric entry.”

The larger object is 85% carbon -the essential ingredient for the organic chemistry needed for life, and the smaller one is 48% carbon. Both contain higher-than-expected amounts of deuterium, a rare form of hydrogen, in a concentration 30 times higher than is usually found mixed with hydrogen on Earth -all elements common in interstellar clouds of dust in deep space, far more ancient than the sun. When the team used a microscope to examine the dust particles they also found tiny crystals which could only have been “condensed or processed at close distances from the young sun.”

The French-Italian scientific base Concordia is located at Dome C in the central region of the Antarctic continent. This is one of the most remote places in the world, where the amount of dust of terrestrial origin is extremely small.
