In German a moon or a star is "am Himmel". "Am Himmel" relates to the sky, whereas "im Himmel" means "in heaven".
Agree, I reported it exactly the same way as described by rfo, hope they get the message, Duolingo made the same mistake with the sun.
Vielen dank für die Erklärung :))
First, "Ist der Mond im Himmel?" was given in the "Type what you hear" exercise, then a minute later it is not accepted as a correct translation. Not nice.
