NASA Seeks Standards for ET Life Claims

The agency wants to develop a credibility scale so we know what to pay attention to

What with everything from Oumuamua to phosphine on Venus claiming our attention, NASA thinks it’s time to develop some standards for what constitutes a credible claim about extraterrestrial life: “The discovery of a potential biosignature in [a planet’s] atmosphere is important, but it’s just the start,” said Green in an interview. “You have to examine potential false positives, whether there are [non-biological] ways to form the chemical, whether the measurement is an artifact of your instrument, whether the environment on the planet is conducive or hostile to life, whether water is present.” Applying such a chain of reasoning could result in a kind of credibility scale for the general public to turn to when they read about new results in…

Researchers: We Don’t See ETs Because They Are All Dead

A recent NASA study suggests that most extraterrestrial civilizations have died out. : The statement comes from researchers with NASA’s Jet Propulsion Laboratory, the California Institute of Technology and Santiago High School who used an updated version of an equation to calculate the likely existence of intelligent life and determined aliens may have emerged some eight billion years after our galaxy formed. With these results, the team included the idea that progress of science and technology inevitably leads to the destruction of civilizations and because humans have yet to make contact outside our planet, scientists now think they know why… ‘If intelligent life is likely to destroy themselves, it is not surprising that there is little or no intelligent life…
