New 12CO J = 4-3 and 13CO J = 3-2 observations of the N 159 region, an active site of massive star formation in the Large Magellanic Cloud, have been made with the NANTEN2 and ASTE submillimeter telescopes, respectively. ... The 13CO J = 3-2 data were newly taken for the present work. ... The N 159 E clump is associated with cluster(s) embedded, as observed at 24нјm by the Spitzer MIPS, and the derived high temperature, 80 K, is interpreted as being heated by these sources. ...

Galaxies are diffuse objects which are imaged against a background of finite brightness and noise. Galaxies which have the maximum contrast with respect to this background are the ones that are first discovered. ... These galaxies have been missed to date but active surveys for them are underway. ... In this page we present several examples of these newly discovered Low Surface Brightness galaxies as well as examples of high surface brightness galaxies. ...
