There is an article in the news section that mentions Brown Dwarf starts and the like.

So appart from extinguished stars there are also many more cooler, less observable stars everywhere in the universe.

Extend my original question to 'Where are all the failed star systems'.

If it is possible, even observable in the solar system, that small objects that do not shine under their own 'steam' outnumber the objects that do shine. Is it not conceivable that the universe is teeming with huge gas giant and gas supergiant systems between the observable stars. I think they are out there and that there are lots of them.
