The ship flying out of the rift reminds me of the XCV-330 Enteprise from the 22nd Century, first seen as part of the Enterprise lineage of ships in a painting in TMP. The ring structure might be a coleopteric warp drive which the XCV-330 used, also used by Vulcan starships.

I think a similar ring design was also an early concept for the Enterprise, before they settled on the familiar saucer + nacelles look.
