@SeanPLynch From the paper
https://iopscience.iop.org/article/10.3847/2041-8213/adc1c8:
"It is widely recognized that the detection of a biosignature is unlikely to be instantaneous or unambiguous in the first instance, rather relying on continued accumulation of evidence..."
"Further work is needed to robustly verify the current findings. More observations are required to robustly demonstrate the repeatability of our present findings, rule out potentially unaccounted-for instrumental systematics, as well as increase the detection significances."
Somehow these (reasonable!) cautious remarks do not square so well with the grandiose-sounding statements of the lead author as quoted by NPR.
