I saved this picture along with explanations of the words, but I lost the explanations, so I leave it to y'all to figure it all out for me again.
B^h^: Blüte means flower in German (compare: blossom)
Dʰ: *Dʰegᵘ̯ʰ: I found the translations burning/fever/day here, maybe the image shows the day side of earth or the indoeuropeans predicted the global warming?
Ǵ^h^: Ast is branch in German
H3: h₃okʷ -> Auge in German, eye in English
N: Nebula in Latin, Nebel in German, Fog/Mist in English
R: Could either be *rēt (stick, rod) or *rēd (advice - "Rat" in German, great grandparent of the English "to read")
Ō: Probably an alternative writing of *k̑u̯on, dog (French chien, German Hund, English hound), afaik noone knows where the Old English dogga came from and why it replaced the already common hound
U: Oxen
Y: jég is ice in Hungarian, jää in Finish and Estonian, but those are not indoeuropean languages‽
