Part of the difficulty in searching for life of any sort is that scientists don’t agree on how life started in the first place—or what life even is. One good attempt at a definition came in 2011 from geneticist Edward Trifonov, who collated more than 100 interpretations of the word “life” and distilled them into one overarching idea: it’s “self-rep...
The first issue of the academic journal Astrobiology, more than two decades ago, featured an article by Kenneth Nealson and Pamela Conrad called “A Non-Earth-centric Approach to Life Detection.” But taking a non-Earth-centric approach isn’t easy for our brains, which formed in this environment. We are notoriously bad at picturing the unfamiliar. “I...
LAB’s research is a combination of fieldwork, lab projects and computation. One project is a planned visit to Canada’s Kidd Creek Mine, which drops nearly 10,000 feet into the ground. Its open pit looks like a quarry reaching toward the seventh circle of hell. At those depths, around 2.7 billion years ago, an ocean floor brewed with volcanic activi...
There is plenty of skepticism outside LAB as well. Some scientists question the need to search for unfamiliar life when we still haven’t done much searching for extraterrestrial life as we know it. “I think there’s still a lot we can explore before we go to life as we don’t know it,” says Martina Preiner of the Royal Netherlands Institute for Sea R...
