Planets are believed to form in these environments when stars are relatively young.

Named after the prototype of the class, UX Ori type variables (commonly called UXOrs) are intermediate mass, pre-main sequence Herbig Ae/Be stars. The light curves of these stars show Algol-like fadings of 1 magnitude or more in random intervals of days to weeks. These fadings are accompanied by a change in color and are thought to be caused by non-uniform dust structure around the star.

It is interesting how nature is almost always beautiful. I have to exclude spiders - though some mad disagree with me.
Surely everyone loves the Tarantula Nebula as well as the amazing Red Spider Nebula?!
