NEWS ROOM: - Are you much talked about news that runs the network for days, under which a NASA scientist have found evidence of the presence of traces of extraterrestrial life in meteorites! Big stuff, no? Let's see the details.
all begins with an article published online in the Journal of Cosmology, here
written by Richard B . Hoover, a scientist from NASA's Marshall Space Flight Center, Huntsville (Alabama). Hoover
This article claims to have found fossil evidence of terrestrial bacteria within some type CI1 carbonaceous chondrite meteorites found in 800 in France and Tanzania.
Analysis by Environmental Scanning Electron Microscopy (ESEM) and Field Emission Scanning Electron Microscopy (FESEM) of the internal structure of these meteorites have shown the presence of long and complex filaments. You see them in pictures of this post.
The article is very long and detailed and is the invitation to the scientific community to analyze the results presented and comment on the discovery.
The whole thing seems really big. The hypothesis that most meteorites - the oldest - contain within them life size fossil suggests the fascinating theory that life could have spread almost everywhere in the universe.
But the scientific method requires an absolute rigor, especially when as in this case the implications are so large size.
Among other things, in an article published UniverseToday ( this ) citing a position of NASA in merito alla questione, eccola
Sostanzialmente l'Agenzia Spaziale Americana afferma di non poter supportare una posizione senza che questa venga esaminata da altri esperti. Relativamente all'articolo di Hoover, lo statement NASA continua dicendo che tale articolo era stato sottoposto nel 2007 all'International Journal of Astrobiology ed il processo di analisi non è ancora stato completato. E mi sembra una posizione assolutamente ragionevole.
Insomma, è ancora presto per dire qualcosa di definitivo. Aspettiamo di avere maggiori notizie CERTE!
