First detection of sugars in meteorites gives clues to origin of life

Billy:

Really gigantic. But something else: life has indeed independently evolved on Earth, as life has also, however, been brought to Earth by comets and meteors from outer space. Anyhow, so I was taught by your father, Sfath, as well as your daughter, Semjase, as well as Quetzal and yourself. This life was indeed so very tiny, only just in the form of micro-organisms. These micro-organisms, that is to say, microbes, are mostly single-celled organisms which can be, according to their tiny size, in the range of only a few microns, made visible by microscopic magnification. To that end, the question is, whether, in outer space and indeed by way of comets and meteors – perhaps by asteroids – such micro-organisms are still being brought to Earth? Sfath told me regarding comets that micro-organisms only reached Earth from these when the comet crashed to Earth or if it passed by very close to the planet or the planet ran into their tail. Only thereby can the microbes then reach the atmosphere and the geosphere, and if I remember correctly, such micro-organisms from outer space are called panspermia by the terrestrial scientists, or anyhow, so I have read it somewhere once. But there are various microbes, and it interests me. Can you say a few words about it?

Ptaah:

There are, if I am to use the terrestrial-scientific terms, eukaryotic micro-organisms which have a genuine nucleus and also exhibit DNA, being micro-algae, microscopically small fungi, protozoa. Next there are the prokaryotic micro-organisms which do not have a genuine nucleus, being archaebacteria, cyanobacteria and eubacteria. But additionally, there is still a third form, which certainly has cells, which however possess no intrinsic DNA, but which, in spite of that, can still replicate at several hundred degrees of heat. But I should not say any more about it, because these things are still unknown to terrestrial scientists. Moreover, they are not endemic to Earth, but only temporarily reach the Earth’s atmosphere and geosphere by way of comets and meteors, that is to say, through their disintegration.

Billy:

Disintegration: what do I need to understand by this? Perhaps a dissolution or some such, as, for example, with a comet’s tail, or by way of an explosion of a comet or meteorite in or over the terrestrial atmosphere? Disintegration indeed actually means as much as “splitting” or even “dissolving”.

Ptaah:

What you say is right, naturally.

An international team has found sugars essential to life in meteorites. The new discovery adds to the growing list of biologically important compounds that have been found in meteorites, supporting the hypothesis that chemical reactions in asteroids—the parent bodies of many meteorites—can make some of life’s ingredients. If correct, meteorite bombardment on ancient Earth may have assisted the origin of life with a supply of life’s building blocks.

The team discovered ribose and other bio-essential sugars including arabinose and xylose in two different meteorites that are rich in carbon, NWA 801 (type CR2) and Murchison (type CM2). Ribose is a crucial component of RNA (ribonucleic acid). In much of modern life, RNA serves as a messenger molecule, copying genetic instructions from the DNA molecule (deoxyribonucleic acid) and delivering them to molecular factories within the cell called ribosomes that read the RNA to build specific proteins needed to carry out life processes.

“Other important building blocks of life have been found in meteorites previously, including amino acids (components of proteins) and nucleobases (components of DNA and RNA), but sugars have been a missing piece among the major building blocks of life,” said Yoshihiro Furukawa of Tohoku University, Japan, lead author of the study published in the Proceedings of the National Academy of Sciences November 18. “The research provides the first direct evidence of ribose in space and the delivery of the sugar to Earth. The extraterrestrial sugar might have contributed to the formation of RNA on the prebiotic Earth which possibly led to the origin of life.”

“It is remarkable that a molecule as fragile as ribose could be detected in such ancient material,” said Jason Dworkin, a co-author of the study at NASA’s Goddard Space Flight Center in Greenbelt, Maryland. “These results will help guide our analyses of pristine samples from primitive asteroids Ryugu and Bennu, to be returned by the Japan Aerospace Exploration Agency’s Hayabusa2 and NASA’s OSIRIS-REx spacecraft.”

Philae allegedly crash lands in the dark, has 24 hours to live

November 14, 2014

Rosetta is a near failure, and yet the ESA is nothing but awkward high fives.   If you’ve heard the sounds and listened to Mythi’s video, 67P already has E.T. mining activity.  But don’t expect any truth from the mainstream media…including  this:

Last chance for Rosetta probe? Scientists prepare to make Philae landing craft ‘hop’ into better position on surface of comet as clock ticks on fading battery power

  • Lander is stuck in partial darkness near a cliff on the rim of a crater
  • It is not getting enough sunlight to keep it alive so engineers may try to get it to ‘hop’ using its landing gear
  • But there might not be enough power to do this until the comet gets closer to the sun in a few months
  • This could mean the lander has to go into hibernation for a few months until it can ‘come back from the dead’  
  • Its main battery only has about 24 hours of power left and the probe needs to receive more sunlight to survive
  • Earlier Philae sent back the first ever images from the surface of a comet, confirming it was in darkness   
  • Probe bounced twice – once up to 0.62 miles (1km) then again to 65ft (20 metres) – before coming to a rest
  • Comet’s surface was described as being more like a ‘trampoline’ than rock, owing to soft and powdery texture

Space Dust Is Filled with Building Blocks for Life

Murchison Meteorite

A study of teeny-tiny meteorite fragments revealed that two essential components of life on Earth as we know it, could have migrated to our planet on space dust.

Researchers discovered DNA and amino acids components in a smidgen of a space rock that fell over Murchison, Victoria, in Australia in September 1969. Previous studies of the meteorite revealed organic material, but the samples examined then were much larger. This study would lend more credence to the idea that life arose from outside of our planet, researchers said in a statement.

“Despite their small size, these interplanetary dust particles may have provided higher quantities and a steadier supply of extraterrestrial organic material to early Earth,” said Michael Callahan, a research physical scientist at NASA’s Goddard Space Flight Center in Greenbelt, Md. [5 Bold Claims of Alien Life]

Amino acids are the basis of proteins, which are structures that make up hair, skin and other bits of living creatures. DNA is a molecule that contains information on building and running an organism.

Size matters

Meteorites such as Murchison are rare types of space rocks: the carbonaceous chondrites make up less than 5 percent of meteorites found on Earth, NASA said. Further, the molecules discovered in these space rocks are usually in miniscule concentrations of parts-per-million or parts-per-billion.

These factors have researchers questioning how significant the carbon-rich rocks themselves were in bringing life to Earth. Space dust, however, is more plentiful as it is constantly available from comets and asteroids shedding debris in their travels through the solar system.

The Murchison study (a proof of concept for further work, the researchers say) found life’s building blocks in a sample that weighed about the same as a few eyebrow hairs. The 360-microgram sample was about 1,000 times smaller than a typical sample analyzed by researchers.

This micro-sample required a more sensitive technique than usual to extract the information scientists needed. A nanoflow liquid chromatography instrument organized the molecules, which were then ionized with a nanoelectrospray for analysis in a mass spectrometer.

NASA and other agencies have dealt with small sample sizes before, such as on the Stardust mission that collected particles from Comet Wild-2 and returned them to Earth in 2006. Researchers anticipate the techniques they are using today could be used for other missions in the solar system, especially for sample-return missions.

“This technology will also be extremely useful to search for amino acids and other potential chemical biosignatures in samples returned from Mars and eventually plume materials from the outer planet icy moons Enceladus and Europa,” said Goddard astrobiologist Daniel Glavin, who was co-author on the research.

The study, led by Callahan, was recently published in the Journal of Chromatography A.
