Mysterious Martian "Cauliflower" May Be the Latest Hint of Alien Life
Unusual silica formations spotted by a NASA rover look a lot like structures formed by microbes around geysers on Earth

The hunt for signs of life on Mars has been on for decades, and so far scientists have found only barren dirt and rocks. Now a pair of astronomers thinks that strangely shaped minerals inside a Martian crater could be the clue everyone has been waiting for.
In 2008, scientists announced that NASAs Spirit rover had discovered deposits of a mineral called opaline silica inside Mars's Gusev crater. That on its own is not as noteworthy as the silicas shape: Its outer layers are covered in tiny nodules that look like heads of cauliflower sprouting from the red dirt.
No one knows for sure how those shapesaffectionately called micro-digitate silica protrusionsformed. But based on recent discoveries in a Chilean desert, Steven Ruff and Jack Farmer, both of Arizona State University in Tempe, think the silica might have been sculpted by microbes. At a meeting of the American Geophysical Union in December, they made the case that these weird minerals might be our best targets for identifying evidence of past life on Mars.
If the logic holds, the silica cauliflower could go down in history as arguably the biggest discovery ever in astronomy. But biology is hard to prove, especially from millions of miles away, and Ruff and Farmer arent claiming victory yet. All theyre saying is that maybe these enigmatic growths are mineral greetings from ancient aliens, and someone should investigate.

(36,988 posts)The Universe was a damned silly place at best . . . but the least likely explanation for its existence was the no-explanation of random chance, the conceit that some abstract somethings "just happened" to be some atoms that "just happened" to get together in configurations which "just happened" to look like consistent laws and then some of these configurations "just happened" to possess self-awareness and that two such "just happened" to be the Man from Mars and the other a bald-headed old coot with Jubal himself inside.
No, Jubal would not buy the "just happened" theory, popular as it was with men who called themselves scientists. Random chance was not a sufficient explanation of the Universe--in fact, random chance was not sufficient to explain random chance; the pot could not hold itself.

Interesting find.......... but we need humans there, to really check it out.
