Two glowing jellyfish-like objects float across Pasadena, CA sky

I'm a 22 year old computer science major from University of Washington, in Pasadena for a co-op job with the Jet Propulsion Laboratory. I stepped outside my apartment (near intersection of E. Del Mar Blvd. and Hill Ave.) this evening to walk to my car and happened to notice two glowing shapes crossing the sky from the North-West. They were irregularly shaped, lumpy, and fuzzy. The best way I can summarize their appearance is to describe them as glowing jellyfish. They seemed to changed shape as they floated silently together across the sky, finally disappearing into the haze above the South-East horizon. They were probably five to ten diameters apart from each other, and about doubled their distance in the time that I watched them. They were side-by-side, although the West-most object lagged slightly. The really strange thing about them was that they each had several blobs inside them that were glowing brighter than the rest of the object. These blobs moved, sort of tumbling around inside. I'm sure there are others out there who got a better view of these objects than me. Many people in the LA area must have seen them, especially since there might have been people out watching the meteor shower that's supposed to be happening tonight. A plane was also in the sky, traveling East to West.
