The comet 67P or Churyumov-Gerasimenko, orbited by Philae and Rosetta, may be home to alien life, according to Dr Max Wallis of the University of Cardiff and Professor Chnadra Wickramasinghe of the Buckingham Centre for Astrobiology. The comet that is being studied by Rosetta and Philae spacecraft since 2014 has distinct body features that could only be explained by the existent of microbial organisms living underneath the comet’s icy surface.
Alien life exists on the comet
Wallis and Wickramasinghe said that data from Rosetta have revealed that the particular comet is an irregular ‘duck shaped’ comet with about 4.3 by 4.1 km in extent. The comet also appeared to have a black crust and underlying ice. More data taken from Rosetta showed large, smooth ‘seas,’ flat bottomed craters and surface peppered with mega-boulders.
“Rosetta has already shown that the comet is not to be seen as a deep-frozen inactive body, but supports geological processes and could be more hospitable to micro-life than our Arctic and Antarctic regions,” Wallis said.
Unfortunately, Rosetta and Philae are both unequipped to explore Wallis and Wickramasinghe’ claims. The proposal from both scientists was said to have received mockery among fellow scientists.
“What we’re saying is that data coming from the comet seems to unequivocally, in my opinion, point to micro-organisms being involved in the formation of the icy structures, the preponderance of aromatic hydrocarbons, and the very dark surface,” Wickramasinghe argued.
Wickramasinghe also said that viral particle may also be present on the comet.
“The current estimate for the number of extra-solar planets in the galaxy is 140 billion plus. Planets that can harbour life are really quite abundant in the galaxy, and the next neighboring system to us is only spitting distance away. I think it’s inevitable that life is going to be a cosmic phenomenon,” Wickramasinghe upheld.
“Five hundred years ago it was a struggle to have people accept that the Earth was not the centre of the universe. After that revolution our thinking has remained Earth-centred in relation to life and biology. It’s deeply ingrained in our scientific culture and it will take a lot of evidence to kick it over.”
Alien life is unlikely
Scientists with Rosetta and Philae are one in saying that claims by Wallis and Wickramasinghe are unfounded.
“I think it is highly unlikely,” Professor Monica Grady told The Telegraph. Grady helped design the Ptolemy instrument carried by Philae.
“It’s pure speculation. I think it is unlikely,” according to Rosetta project scientist Dr Matt Taylor.
