Hoover claims ET-bacterial life on Meteorites.

[KABOOM]

Fascinating topic. Enjoy. Cyanobacteria not of this world???????????

The link is actually to 20 or so peer comments on the paper by Hoover, which was 10 years in the making.
Some my find these snippets easier to digest than the paper itself (which I'll post later)

Warning: The Journal of Cosmology does tend to be a little "out there" (no pun intended) to many hard core sceintists. That said, Hoover's paper is out there for full "peer review" and while given the "evidence" with which to work one will can never 100% certain, it is plausible and has some backing to it. Also, the comments of the 20 sceintists are skewed in a panspermia-friendly direction.

Richard Hoover of NASA has discovered evidence of microfossils similar to Cyanobacteria, in freshly fractured slices of the interior surfaces of the Alais, Ivuna, and Orgueil CI1 carbonaceous meteorites. Based on Field Emission Scanning Electron Microscopy (FESEM) and other measures, Hoover has concluded they are indigenous to these meteors and are similar to trichomic cyanobacteria and other trichomic prokaryotes such as filamentous sulfur bacteria. He concludes these fossilized bacteria are not Earthly contaminants but are the fossilized remains of living organisms which lived in the parent bodies of these meteors, e.g. comets, moons, and other astral bodies (JournalofCosmology.com March, 2011).

Ancient cyanobacteria are responsible for creating oxygen in earth's atmosphere. Maybe the first cyanobacteria to do so arrived here from afar by meteor showers? If so, life could be expected anywhere and everywhere in the universe.

Apostate!

Heretic!

Next thing you know,

The author will be claiming that

The Earth revolves around the sun.

Do not pay any attention to this dangerous idea.

You will go blind and not be able

To make babies!

hoka hey

They must be pretty tough.
Able to survive the cold of space and then the heat of atmospheric entry.

I put seeds and bacteria in a hard vacuum and at -20F all the time,
they keep longer that way,
and the inside of some of the meteor types don't heat up much on entry,
and then cool off by the time they hit the ground,

I am not saying that it happens often,
but it only needs to happen a few times,
but I really think that lots of regular bacteria types would do just fine, especially the spores and eggs and the like.
just try to kill all the green algae, it is just everywhere on earth and should live just fine in conditions like that

From what I can piece together, a school of thought on this topic is somewhat as follows:


1 Supernova in the neighborhood. Gasses, metals, minerals unleashed everywhere as planets surrounding such star explode as well (as do neighboring planetary systems).

2. Mega materials for star formation are now everywhere. Cosmic debris (apologies to Frank) with fossilized bacterium from planets in 1 abound.

3. New stars form, like Sol (our sun)

4. Protoplanetary disc surrounds sun, containing all known elements, heat, cool, radiations, ingredients for H20, H20 when mixed with cosmic debris spawn new bacterium. Planets, comets, Oort cloud material all congeal form and jockey for orbitting positions.

5. Chaos subsides. Solar System takes shape. Much of the original protoplanetary disc materials never congeal into a planet and freelance (comets, etc).

6. Freelance materials bombard inner rocky planets (Earth). Ingredients only, OR already prepackaged functional bacterium (or both) arrive. Nature takes its course. 3.7 billion years later -- look in the mirror.
