For the last few decades NASA has been leaving few stones on the surface of Mars unturned—quite literally in some cases—in the search for extraterrestrial life within our own Solar System. But now an international team of researchers has found what may be a biosignature in the atmosphere of the
NASA has announced the creation of a new position within the space agency titled "Planetary Protection Officer" (PPO), and is currently looking for candidates suitably qualified to protect the Earth — and other planets — from possible biological contamination. The salary for this singular position will be between $124,406 to $187,000 per year, with the successful applicant being responsible for preventing the transmission of potential contamination to and from Earth by astronauts and space probes during their expeditions.
Two new studies have been released that illustrate that the dry Martian lakebed that is currently being explored by NASA’s Curiosity rover was home to a habitable environment for over 700 million years, and possibly for well over a billion years.
What if we’re looking for alien life in all the wrong places? In response to the current search for alien life in sources beyond Earth, Penn State astronomer Jason Wright has published a paper titled "Prior Indigenous Technological Species", putting forth the idea that there’s the possibility that we mightn’t have to look too far afield to find traces of technologically-advanced alien civilizations, as there may very well have been some that evolved right here on our own planet, in Earth’s distant past.
