MrSeb writes: "Researchers at Cardiff University in the UK have found algae-like fossils in meteorite fragments that landed in Sri Lanka last year. This is the strongest evidence yet of cometary panspermia — that life on Earth began when a meteorite containing simple organisms landed here, billions of years ago — and, perhaps more importantly, that there’s life elsewhere in the universe. These findings aren’t a slam dunk, though. There’s a possibility that the fossils aren’t actually biological in nature — they simply look biological. There’s also the fact that the research was published in the Journal of Cosmology, a peer-reviewed journal that has come under critical scrutiny numerous times since it was established in 2009. The journal faced a lot of controversy when it published a paper by NASA engineer Richard Hoover claiming to have found fossils “similar to cyanobacteria” in meteorites. One thing’s for certain, though: For this to actually become science — for Chandra Wickramasinghe’s dream of panspermia to become a reality — this work will need to be replicated by many other groups around the world. It would be very, very exciting indeed if biological fossils have been found on an extraterrestrial meteorite. It would be proof that there’s life on other planets — and essentially a guarantee that the universe is full of life. But, as always, extraordinary claims require extraordinary evidence."
