yep, as far as I know, beside earth and most of human artifacts launched in the close universe there are no terrestrial (at least) bacteria, or other life forms :)

And on our earth, you can expect that lava, sulfuric acid ponds found in nature (close to sulfur sources) and other limited but hostiles places like this are quite sterile.

Yep, space, stars, other planets, they don't contain life... or it hasn't been discovered yet. There could be alien life form but not look like bacteria.

On Earth, air contains some bacteria, but they are not naturally airborne; very small number of bacteria are found in the upper atmosphere due to sterilizing effect of sunlight.

If you're just referring to the Earth which I got the impression you were there are some extreme evironments where only Archaea can surivive, like some hot springs.

Members of the group Bacteria are indeed not found in several harsh environments on earth. For example, members of the Bacteria group are rarely found thriving in glaciers, salt, or near hydrothermal vents. However, several Archaeans are known to prefer such environments.

Yup..some bacteria like Aquifex live in harsh environments and grows optimally in temperature about 80ºC - 100ºC.

Some bacteria even eat radio active waste/Uranium!

Hmm...then I think that we can use this bacteria to degrade those nuclear waste in the nuclear power plant...

What seriously?!!! Well isn't that a far better solution than burying it?

Bacteria can't eat those. I think Linn might be referring to the element uranium itself although it's still incredible!
