Optical image of the Rosette Nebula (NGC 2237- 2239). About 2600 light years away,it is a giant cloud of dust & hydrogen some 100 light years across. It is ionised & lit up by the open cluster of young,hot stars (NGC 2244) at its centre. Part of the nebula contains thin dark filaments composed of interstellar dust; they appear to be condensing into round blobs known as Bok globules,which are believed to be regions where star formation takes place. The photo was taken with the UK Schmidt Telescope in Australia | |
