ESO’s 60th anniversary image: the Cone Nebula as seen by the VLT
The image shows the Cone Nebula at the centre of the picture taking up most of the frame. The shape of the dark nebulous cloud is that of a cone, pointing upwards. At the top and surrounding the cone are bright yellow stars of different sizes, tiny dots and bigger gassy spheres. To the left of the central figure, abstract dusty patterns are fading upwards. The top shines brightly, lit up by luminous stars. The Cone Nebula is part of a star-forming region of space, NGC 2264, about 2500 light-years away. Its pillar-like appearance is a perfect example of the shapes that can develop in giant clouds of cold molecular gas and dust, known for creating new stars. This dramatic new view of the nebula was captured with the FOcal Reducer and low dispersion Spectrograph 2 (FORS2) instrument on ESO’s Very Large Telescope (VLT), and released on the occasion of ESO’s 60th anniversary.

Update 2014 Mar 23: Replaced it with better noise reduction. Probably not noticeable unless you look at it zoomed. It does have slightly better fidelity even at gallery size, though.
Messing around with the cone nebula and seeing what had already been done with these data I discovered there are some interesting structures which become hidden if you try to cram the near-infrared and H-alpha both into the red channel where they technically belong. I am probably committing some form of processing heresy by representing H-alpha with blue-green but to hell with convention. Please compare it with this image, at HubbleSite.
Reddish orange colors are representing near-infrared data. Greenish blue colors are H-alpha. Blue is a wideband blue filter.

North is almost up. It is 4.5° clockwise from up.
