Time for some Xenology once again.
As we all await
Curiosity's landing on Mars, we have been having some fun
thinking about what would happen if the rover suddenly encountered a Martian.
Of course, as previously mentioned, Curiosity does not have the
ability to detect life if it was there. Instead, Curiosity will look for the ingredients of life.
So, what would happen if an alien life-form suddenly stood staring at the rover? Sadly, not much. Curiosity would not recognize it as a living alien being.
It is almost a little ironic, but Curiosity is not a life detection mission.
But let us return back to the fascinating subject of aliens on Mars. What would a Martian look like anyway? Actually, no-one really knows, but many
scientists have speculated about alien physiology.

Extraterrestrials can be of different sizes and shapes, and these beings can be so alien that we might not even recognize them, even if we found ourselves
face to face with them.
We have created a public image of what ET will look like, but we tend to forget alien life-forms do not need to be humanoids at all. We cannot expect to find little green men.
"ET looks like a cute three-year-old child. But that is just for dramatic purposes, within the film.
If you ran Planet Earth again, the chances are you wouldn't get vertebrates. You wouldn't get creatures with a jointed spine, " Cohen says.
Early artists often pictures aliens living on Mars as silicon-based creatures. "Life on Mars" was envisioned as low to the ground, symmetrical and simple,
as you can see on this image below taken from the NASA archives.

The artist drew silicon-based life forms, probably coached by others, perhaps scientists, who had thought about such possibilities.
Peculiar saucer-like shapes stood only slightly above ground level, root-like structures reached outward for growth resources; a bundle of cones faced many
directions for heat, light or food. Instead of reality, the images embodied the artist's hope and anticipation of what future Martian exploration would find.
This composite of three artists' renderings from 1975 was only wish fulfillment for an unnamed JPL artist; however, the landscape and the rendered shapes
took into account what was known about Mars that year.
Compared to Earth, Mars is further away from the light of the sun,
very cold and very arid, and had a thin atmosphere rich in carbon dioxide but little nitrogen, an environment distinctly inhospitable to complex, Earth-like,
carbon-based life forms.
Aliens will most likely not look like little green men.
In The War of the Worlds by H.G. Wells, the Martians are depicted as a technologically advanced race.
They're described as large tentacled creatures much like octopuses who use a combination of heat rays, chemical weapons, and fighting robots called
tripods to wipe out humanity and drink their blood without even bothering to explain why they're doing it.
That is a grim picture indeed!
Maybe it is good after all that we are looking for just bacteria and that Curiosity is not able to recognize life.
More exotic types of alien life might be here already, but we are just not able to recognise them, Cohen and Stewart write in their book, but
they also point out it is the chances of life being found on the Red Planet are slim.
"Certainly aliens would not look like the canonical little green men... unless they wanted to.
"They might look exactly like people. Or cats. Or houseflies. Or they could be invisible, or lurking just outside our space time continuum," Cohen says.
Who Put The Monolith On Phobos?
A satellite of the planet Mars, Phobos, discovered by A.Hall in 1877 still attracts great attention.
"We should visit the moon of Mars. There is a monolith there, a very unusual structure on this little potatoes-shaped object
that goes around Mars," said former astronaut Buzz Aldrin in an interview with C-Span some years ago.
His words confirmed the existence of a mysterious structure on Phobos, one of Mars' two moons.
Shockwaves Could Crinkle Space-Time Creating A New Kind Of Singularity
Mathematicians have discovered a new way to crinkle up the fabric of space-time, at least in theory.
"We show that space-time cannot be locally flat at a point where two shock waves collide," said Blake Temple, professor of mathematics at UC Davis.
"This is a new kind of singularity in general relativity."
Extraterrestrial Life Is A Censored Subject Says Famous Professor
It is not often scientists are willing to openly discuss the possibility of extraterrestrial life.
According to a famous astronomy professor there is a reason why a majority of scientists avoid the subject - it is censored!
Even though the general public embraces ideas of extraterrestrial life, science is expected to shun this subject no
matter how strong the evidence, albeit through a conspiracy of silence.
Gullies On Mars Formed By Water
A new study reveals that parts of Mars may have been modified by liquid water in recent geologic times, which might indicate more
favourable conditions for life on the planet.
The surface of Mars displays a diverse landscape, and a new study shows that large areas of the northern hemisphere have undergone
a number of freeze-thaw cycles.
Alien Message Can Be Hidden In Your DNA
Do We All Carry A Cosmic Greeting Card?
While SETI is busy searching for signals from alien civilizations, there are scientists who think we can find proof of advanced
extraterrestrial life much closer to home - namely in our DNA!
Instead of leaving artefacts for humans to find once they are sufficiently evolved, an advanced extraterrestrial civilizations
might instead incorporate information into the human genome, allowing it to be copied and maintained over immense periods of time.
