Comet lander Philae may be sitting on an object teeming with alien microbial life, according to two leading astronomers. Distinct features of the comet 67P/Churyumov-Gerasimenko, such as its organic-rich black crust, are best explained by the presence of living organisms beneath an icy surface, they claim. The experts go as far as to suggest the comet is more hospitable to life than the Earth's polar regions. Rosetta, the European space craft orbiting the comet, is also said to have detected strange 'clusters' of organic material that look suspiciously like viral particles. But neither Rosetta nor its lander are equipped to search for direct evidence of life after a proposal to include this in the mission was allegedly laughed out of court.Leading space experts say comet may be capable of housing microbial lifeEven suggest comet is more hospitable to life than Earth's polar regionsCalculate that its distinct feature point to presence of living organismsProfessors plan to include life-detecting device on lander was laughed at
