Observing a cool object that size away from any star would be very difficult, but this one's glowing in the infra-red and visible spectrum so it's much easier. Hence I think we're far more likely to observe young objects like this one, even though they must be pretty rare compared to much older ones that have cooled down to low temperatures. | |
