Star Trek Discovery: Every Easter Egg & Hidden Reference From 'That Hope Is You'

After colliding with the Nautilus, Michael (and Book) crash land on the planet Hima.
While Michael's intention in "Such Sweet Sorrow, Part 2" was to take Discovery and meet up with her mother on the planet New Eden (from the episode "New Eden"), she and her ship are clearly off course.
Most of "That Hope is You" takes place on this new alien world and was filmed last summer in Iceland. Iceland was previously used for VFX plate shots of the unnamed planetoid on which Doctor McCoy and Carol Marcus performed torpedo surgery in Star Trek Into Darkness.
