In the early 2000s, Phil Plait wrote his first book, Bad Astronomy, which debunked conspiracy theories and fallacies, like the idea that NASA faked the moon landings in the 1970s or that planetary alignments can affect life on Earth. Twenty years later, he’s continuing his quest to quash astronomical misconceptions while sharing his love for the cosmos. Plait, an astronomer and science writer, has spent his career sharing space news and explaining complex concepts to the public through his popular blog and newsletter, both called Bad Astronomy.
