No Wonder, that life does exist somewhere in the endless universe.
Soon it may be that we find the traces of life to be at the arms lenght from our planet.
Evidence is building to suggest biological processes might be operating on the red planet, and life on Mars, many scientists believe, is now more a likelihood than merely a possibility.
Tantalizing evidence is accumulating that suggests the red planet is alive, but incontrovertible proof is still lacking. And while the European Space Agency is keen to send a lander to find it, a history of failed life-finding missions at NASA makes Americans more cautious.
"The life on Mars issue has recently undergone a paradigm shift," said Ian Wright, an astrobiologist at the Planetary and Space Sciences Research Institute at the Open University in Britain, "to the extent now that one can talk about the possibility of present life on Mars without risking scientific suicide."
Formisano showed evidence of the presence of formaldehyde in the atmosphere. Formaldehyde is a breakdown product of methane, which was already known to be present in the Martian atmosphere, so in itself its presence is not so surprising. But Formisano measured formaldehyde at 130 parts per billion.
To astrobiologists it was an incredible claim. It means huge amounts of methane must be produced on Mars. (While methane lasts for hundreds of years in the atmosphere, formaldehyde lasts for only 7.5 hours.) "It requires that 2.5 million tons of methane are produced a year," said Formisano.
"There are three possible scenarios to explain the quantities: chemistry at the surface, caused by solar radiation; chemistry deep in the planet, caused by geothermal or hydrothermal activity; or life," he added.
And, with no known geological source of formaldehyde on Mars, it's clear where Formisano's suspicions lie.
"I believe there is extremely high probability that microbial subsurface life exists on Mars," he said, while acknowledging that although he believes in Martian life, he can't yet prove it.
"What will certainly be needed in the future is a drill on a lander and direct evidence of the existence of Archaea bacteria," Formisano said, adding that he intends to publish his data in a forthcoming issue of planetary science journal Icarus.
The European Space Agency certainly wants to send a rover to Mars, and was urged to do so at an international space workshop at Aston University in Birmingham, England, earlier this month. To get a lander on Mars will almost certainly require the involvement, at some level, of NASA.
But NASA has its own surface mission planned. Scheduled to arrive in late 2010, the Mars Science Laboratory rover will use an array of instruments to look for evidence of life.

Fujitsu has announced that the University of Tokyo Hospital's room access security system will now use their contactless palm vein authentication technology. Palm veins are unique amongst individuals, and with the exception of size, don't change at all over one's lifetime. They offer more consistent readings throughout different environments and are not much affected by other factors like cold weather, injury and chafing. Since the unit is also contactless, its deployment makes perfect sense in a hospital, where you obviously want to try to touch as few surfaces as possible. We briefly mentioned a similar device
