Wow that is impressive! I always take notice of the bystander! I think collisions between galaxies are quite romantic!

I love that image - and I get a kick out of the galaxy! What a galaxy and what an image!

NGC 4485 is a quite blue galaxy (and you know what I think about that ).

In James D Wray's Color Atlas of Galaxies, NGC 4485 looks all green and a bit blue, with no trace of yellow at all. The colors suggest a galaxy all composed of young and intermediate-aged stars. I would be extremely surprised if there was not an underlying yellow population in NGC 4485 after all, because there appears to be practically no "newborn" galaxies in existence. In fact, there appears to be a halo of faint red stars surrounding NGC 4485, even though more of those red stars appear to be associated with NGC 4485's "dance partner": NGC 4490.

The B-V index of NGC 4485 is 0.39, and its U-B index is -.22. That's blue, indeed.

ESO: First Results from the ESO Ultra HD Expedition

The ESO Ultra HD Expedition may now be over, but there is much work being done behind-the-scenes to process and combine all the footage the team has taken — a staggering 10 TB of images and video. With four times the resolution of HD, Ultra HD takes our view of the night sky into a new, immersive dimension. The expedition team can now present some of their first results in dramatic Ultra HD footage — bringing the Universe closer than ever before. ...

ESA/HEIC: Hubble sees a flickering light display on Saturn

Astronomers using the NASA/ESA Hubble Space Telescope have captured new images of the dancing auroral lights at Saturn’s north pole. Taken from Hubble’s perspective in orbit around the Earth, these images provide a detailed look at Saturn’s stormy aurorae — revealing previously unseen dynamics in the choreography of the auroral glow.

It would gain from being labelled with the various features that APOD is so good at, without distracting from the granduer of the scene.

Wow it is impressive to see a closeup of this very small nebula! You can see the whole Circinus Cloud in this widefield image by Marco Lorenzi.

Copyright: Steve Crouch This very faint planetary nebula is one of more than 1000 new southern planetary nebulae in the MASH catalogue, which were discovered in the SuperCOSMOS Ha Survey (previously known as the AAO/UKST Hα survey). The catalogue can be accessed here: http://vizier.u-strasbg.fr/vizier/MASH/index.htx
Quite a lot of them also exhibit OIII emission and some are fairly bright.
