[QUOTE="ifmihai, post: 6003700, member: 325217"] Amazing thread! Thank you very much for the pictures. They are great! They say a lot more than reading. I have a question. Is there something like an equinox, as seen from sun? When galactic center crosses sun's equator? Hard to imagine if this is even a pertinent question, but i couldn't answer it myself. What seems to confuse me is the large spans of time and space involved. From what i got from this thread, it appears solar system crossed galactic equator around 3Mil years ago. Was that the moment that could be considered as an equinox? Is there such a point or area in the sky, representing this equinox moment? Ps. Also, to me it seems a little strange, that ~3 million years number. Kind of coincides with homo erectus location in time, more or less. [/QUOTE]
