Lab Notes: When astronomers make mistakes

In March 2018, a South African astronomer looking into the distant universe "discovered" a bright red spot in the sky that hadn't been there previously; it felt like an exciting potential discovery. A message was sent to other astronomers, asking them to look at this new dot and study it further.After forty minutes and a few more calculations, he realised this "star" was much closer to home and nothing new at all: it was the planet Mars.According to Dr Kat Ross, making this kind of mistake is something of a rite of passage for astronomers.You can binge more episodes of the Lab Notes podcast with science editor and presenter Jonathan Webb on the ABC Listen app (Australia).
