Giant Bones Discovered In Martian Soil

No, not really. Would be something though, wouldn't it?

The new study doesn't change the picture for life on Mars. The researchers say the temperatures they measured are too low and water too scarce "to support terrestrial organisms" (sorry, bunny fans).

But scientists say evidence of water ice at the planet's poles and now more evidence toward the theory of widespread brines keeps them hoping they'll find evidence that life at least once existed there.

Giant bones of Mars are nothing new.

Here, we see a picture of early-twentieth-century astronauts with a giant skull they unearthed (or should that be unmarsed?).



As you might have surmised from this picture, early astronaut training was not concerned with space walks etc., but concentrated primarily on the ability to hold one's breath for extended periods.
