Once again, don’t trust the output of any #AI assistant without verification. This is not the HR 8799 exoplanet system, it’s the YSES 1 exoplanet system. Source: my (then) grad student Alex Bohn took this image using VLT/SPHERE. #astrodon #astronomy #exoplanets

An image of the YSES 1 exoplanet system as posted on X by a farming account, with someone asking Grok "what is this system?" and Grok confidently giving completely the wrong answer.
