Not human life but so-called Extremophiles.
What are they? Well The 26th June 2015 BBC Radio 4 Programme 'In Our Time' chaired by Melvyn Bragg will explain with speakers:
Professor of Planetary and Space Sciences at the Open University
Professor of Planetary Science and Astrobiology at Birkbeck University of London
Reader in Evolutionary Biochemistry at University College London
Link To In Our Time - Extremophiles
The discussion was about Extremophiles and group of organisms that thrive in physically or geochemically extreme conditions that are detrimental to most life on Earth. In contrast, organisms that live in more moderate environments may be termed mesophilesor neutrophiles. They were first identified in 1977 when the submersible 'ALVIN' was used to go down to over 2000 metres off the Galapagos Islands and found Hydro Thermal Vents of super heated water apparently teaming with life despite the extreme temperature and acidity.
In the words of Star Trek 'Its Life Jim But Not How We Know It'. Since then a huge class of Extremophiles have been found in diverse extreme locations and a new science has emerged.
The radio programme is excellent listening, with well structured arguments and theories all of which is evidence based. I recommend listening to this and them casting another glimpse at my videos of Ceres, it the pyramid turns out not to by ' creature made' which it most likely will be, then it is possibly a very large inactive volcano and my well have within it the type of conditions in which Extremophiles may have been or may still be in residence.
If you knew to science and history, or suspect of it In Our Time is an excellent place to broaden your horizons. This episode is very pertinent to the DAWN mission to Ceres, co-incidentally ;-)
