Hi. The Mathmos Jupiter 2 (there was no Jupiter 1) came out in the mid-90's and, I guess was the spiritual successor to the Crestworth Galaxy (in my opinion) as it was a high end market, domed fibre optic lamp. They are quite sought after at the moment and examples can easily reach three figure sums, say 200 pounds UK. I don't think production lasted long as there aren't many of these about, in fact you see al lot more crestworth galaxys and they were from 20 years earlier. There's a Jupiter 2 on German Ebay at the moment.
