Comet 67P harbors oxygen molecules as old as the Solar System

I wonder if it smells stale.

We have new data from the Philae lander – it identifies several new organic molecules on Comet 67P, charts internal structure

Two different Philae instruments, known as Ptolemy and COSAC (Cometary Sampling and Composition), hunted for organic compounds— the building blocks of life as we know it — on and around Comet 67P.
While the initial data burst received from the lander did hint at the existence of organics on its surface, the data was limited and its meaning not very clear.
The new data is much more interesting.

Philae could be sitting on a comet filled with alien life and not even know it

Comet lander Philae may be sitting on top of microbial life and not even know it – even worse, it has no way of figuring out if it actually is. According to two researchers, the comet’s characteristics (as well as computer simulations) might indicate that the surface may be teeming with microbes. The Rosetta spacecraft was launched in March 2004 by

Rosetta spacecraft finds huge sinkholes on comet’s surface

Rosetta is a robotic space probe built and launched by the European Space Agency. Along with Philae, its lander module, the craft is performing a detailed study of comet 67P/Churyumov–Gerasimenko. The probe usually orbits 67P at a distance of a few hundred kilometers. Footage received from Rosetta over the last year showed a number of dust jets coming from the comet,
