Late on Friday, the Journal of Cosmology (a free of charge but peer-reviewed scholarly journal) published a paper on their web site by NASA astrobiologist Dr. Richard B. Hoover that showcases a selection of microscopic fossilized structures from within meteorites that are probably the remains of extraterrestrial germs. Aliens, for true.
Naturally, if these structures prove to be the actual stays of alien bacteria, this is unbelievably enormous reports. We're conversing one of the most substantial discoveries in human historical past, proving that life (in some type) is not only not special to Earth, but in simple fact likely prevalent through our solar system on comets and moons and probable just as prevalent across the tens or hundreds of billions of other planetary bodies in our galaxy. It also implies that life itself almost certainly didn't originate on Earth, but possibly came below from space. It really is absolutely thoughts blowing.
So here is the deal on what Dr. Hoover found. He sterilized, and then minimize open a bunch of carbonaceous chondrite meteorites, which are meteorites that have a tendency to contain tons of drinking water and natural content like amino acids. Hoover then examined the freshly uncovered insides of the meteorites with an electron microscope, and inside he identified lots (tons) of what he says look to be 'indigenous fossils' of bacteria. Numerous of the fossils were embedded immediately in the rock, and the absence of nitrogen in them helps make it not likely they they came from Earth, according to Hoover. So in this circumstance, 'indigenous' means that the bacteria could have arrived on Earth alongside with the meteorite: natively, they'd be aliens. ALIENS!
