Triangulum spiral

Triangulum spiral

(M33; NGC 598) A spiral (Sc) galaxy in the constellation Triangulum that is the third largest of the confirmed members of the Local Group and is about 800 kiloparsecs distant. Although it is both smaller and more distant than the Andromeda galaxy it can appear larger because it is orientated face-on to us. The spiral arms are more open than those in our own Galaxy and the nucleus is relatively small and faint. It has a large number of young population I stars.

Discovering novae in the Andromeda and Triangulum spirals and other nearby galaxies will be just the beginning of what future amateurs might do if they tap into the pipeline of data flowing from the LSST.
