Re: APOD: Galaxy Cluster Abell 1689 Magnifies... (2010 Aug 2

Hi, At the upper right of the Abell 1689 image (yellow box) I noted two galaxies with what may look like supernovae. I know it seems unlikely, are those just intervening stars or what? http://geoserv.ipfw.edu/~tennisc/pics/abell1689_hst_600_select1.jpg http://geoserv.ipfw.edu/~tennisc/pics/starpoint...

Aging Galaxy (APOD 17 Oct 2007)

Is it true, there are no stars in this picture ( APOD Oct. 17, 2007? )
Are all the points of light in the galaxies presented star clusters? And are all the other smudges and points of light outside of the galaxies other galaxies?
