I have pulled data from three sources (NRAO, HLA, Hubble Heritage Team-wikipedia) and processed over the past 2 weeks. I offer this for consideration for APOD. THANK YOU!

I took this picture near Rolla, MO on September 9th, 2013 at sunset… Nifty cloud shadows…

PR Image eso1339d: Hubble view of galaxy NGC 4710 with X-shaped bulge (NASA & ESA)
Two groups of astronomers have used data from ESO telescopes to make the best three-dimensional map yet of the central parts of the Milky Way. They have found that the inner regions take on a peanut-like, or X-shaped, appearance from some angles. This odd shape was mapped by using public data from ESO’s VISTA survey telescope along with measurements of the motions of hundreds of very faint stars in the central bulge.

ESA/Hubble Photo Release heic1317 - New Hubble image of galaxy cluster Abell 1689
This new image from Hubble is one of the best ever views of the massive galaxy cluster Abell 1689, and shows the phenomenon of gravitational lensing with unprecedented clarity. This cluster acts like a cosmic lens, magnifying the light from objects lying behind it and making it possible for astronomers to explore incredibly distant regions of space. As well as being packed with galaxies, Abell 1689 has been found to host a huge population of globular clusters.
