Help with lojbanizing the black hole

[Yann Le Du <yann.ledu@noos.fr>]

Hello,

Trying to find some words in lojban related to cosmology, I found this 
page : http://www.lojban.org/tiki/tiki-index.php?page=Astronomy

I'd like to suggest something for the "black hole" but, being only a white
belt lojbanist, I am unable to construct the following word with {jvinu} :
"that which is viewed as black from outside" (a definition that keeps the
useful observational information contained in "black hole" but that also
avoids the pitfalls of literal translation).
