Same vibe, no. Vangelis was one of a kind. But somewhere in the same galactic neighborhood:
Maurice Jarre (The Witness, Gorillas in the Mist)
Bear McCreary is mostly orchestral, but the "Cult of Baltar" cue, for example, seems to me cut from some of the same corners of the world/ambient universe.
Cliff Martinez has done a ton of great ambient synth stuff (Traffic, The Neon Demon, Drive).
Other synth soundtracks you may already know, but should check out if you haven't: Wendy Carlos's TRON and Daft Punk's TRON: Legacy; Brad Fiedel's Terminator; Tangerine Dream's various soundtracks.
