Everyday, NASA releases an Astronomy Picture of the Day (APOD) http://apod.nasa.gov/apod/

This thread is to discuss these images.

The archive for APOD http://apod.nasa.gov/apod/archivepix.html

Previous spectacular posts in the Forum demonstrate what we can learn from Hubble images.

2014 July 15 A Blue Bridge of Stars between Cluster Galaxies http://apod.nasa.gov/apod/ap140715.html

likely a bridge created by tidal effects between the two merging central elliptical galaxies [...] The knots in the bridge are condensation regions that glow blue from the light of massive young stars.

Lots of gravitational lensing, and a very red galaxy

Galaxy Cluster SDSS J1531+3414

SDSS J153110.60+341425.0

Hubble images do not have N at the top, so the Hubble image is rotated slightly clockwise.

There is a spectrum http://skyserver.sdss3.org/dr8/en/tools/explore/obj.asp?id=1237661851485929746. Can you see the OII and OIII peaks?
