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

OIivier Giroud and Theo Walcott's battle for Arsenal's striking berth is emerging as one of the most intriguing rivalries of the season. There have been great player rivalries over the years – Cesc Fabregas and Frank Lampard, Diego Costa and Martin Skrtel, Roy Keane and Patrick Vieira, Alan Shearer and Alf-Inge Haaland – but they are generally found between players from opposing sides (Lee Bowyer and Kieron Dyer aside).
