Moire patterns (properly aliasing artefacts) occur when a semi-periodic pattern below the limit of resolution of the CCD occurs in the image, not in random noise patterns. Thus the signal needs some semi-periodic component to get these artefacts. I have seen hundreds of astronomical images taken below the resolution limit of the optics, and have never yet seen Moire-like aliasing artefacts.
Auroras are often magnificent, but this adds a whole new dimension (38 actually, from 3D RGB to 41D hyperspectral)!
I wonder if the airglow wave pattern is in some way similar to ionospheric waves seen by the LOFAR antennae. Those seem to occur at higher altitude, but I wonder if similar mechanisms trigger them (or that there is some coupling between ionospheric waves and the low altitude wave pattern seen here).

Re: Should be mandatory declared
Good idea. Some appraisal systems I have seen could very efficiently be replaced by throwing darts. You simply take the score modulo 5 and there you are!
Some employees might prefer throwing darts at senior management, however.
This might be taken as meaning that you are taking these badges FAR too seriously

If they were really serious about the pink look, they would have labelled all the pink buttons in pink on a pink background and have a little pink light light up pink to show that you have pressed it.

Absolutely. The BOFH for one would love to wave one around in the boardroom.
Where on earth can you still get a spare 500 MB drive?
If you want one like that, maybe you can also use my 8" floppy disk (128 kB storage!!) with CP/M2.0 on it (official copy).

Or maybe these are stars surrounded by a fleet of black Haggunenon battle cruisers (the ones with the black instrument panels, with black buttons which are labelled in black on a black background, and whenever you press one of them a little black lamp lights up black to show that you have done it), which blot out the light of the star.
Either that or

I must say I am curious, but the ASUS Transformer series still seems to fit my needs a bit better (that and a fast 13 or 14" notebook with good graphics grunt)
Re: Asked in jest
Astronomers use FITS = Flexible Image Tape System. It typically uses 80 byte records called "card images". That alone shows its age.
We are just adapting our code to handle FITS. I would love to put our parallel code through its paces on this image (biggest we have done so far is 3.9 Gpixel).
Of course the whales were making a racket back then!

Tedium? Well yes, I suppose. "Inserted into a cow's vagina" might well be the result of near terminal boredom (but not on the part of the cow, I presume)
I am somehow torn between to emotions, i.e.:
1. HOW ON EARTH DID IT GET THERE??!!
2. I DO NOT WANT TO KNOW how it got there
Games are not the only reason for wanting graphics clout. Physics simulation and 3D visualisation of medical data (MRI and CT scans) require more grunt. For many people the HD 4000 might be OK, but there are those whose work depends on graphics power.
Re: The only snag...
"Most people use wifi or do not see an issue leaving a small and relatively cheap adapter on their Ethernet cable."
The problem is not that I mind having an adapter on my ethernet cable at home (though it is a potential problem when someone detaches it to use their native port, the adapter can get lost). My problem is when I want to use ethernet elsewhere (visiting other institutes, e.g.). It is just another thing to pack, no deal breaker, but still a bit of a hassle. If the things had a decent graphics card, I could certainly live with an ethernet dongle.
Re: The only snag...
No nVidia = no CUDA = no use to me. I also MUCH prefer ethernet, as I routinely do need bandwidth. Real pity as this machine ticks a lot of boxes for me. It looks really nice, I love the high resolution, and light weight. My current lightweight (13", 1.69kg) really needs replacement, but I need a machine with nVidia graphics and ethernet. Using a dongle is a pain, in my view.

Largest things in the universe?
It depends on what you think is a single "thing," I suppose. Clusters of galaxies are larger than 2 million light years. Super-clusters are bigger still. These are organized in walls and filaments, and these in turn form the cosmic web. Quite a few people say the cosmic web is the largest thing.
Still an impressive jet.
A colleague of mine at first logged all (failed) attempts at getting through his router, but gave up full logging because the log file started to grow alarmingly fast. Generally attempts by script kiddies at that point in time, plus some more concerted efforts to break in (usually eastern Europe or Far East). And yes, neither his nor my home router's settings are the factory defaults, only the bare minimum of ports are open to allow internet access. And then there is still no reason for complacency.
Agreed, Steve, it is! it is fucking obvious
Somehow the fucking obvious escapes many people
Take politicians. How many projects are out there based on the premise that as long as we collect ALL the data we will be in a better position to find terrorists/paedophiles/other undesirables? Lets take fingerprints from everybody entering the country! Hooray!! We have struck a blow in the war on terror!!!
No, you are just showing the general public that you are doing something, by pissing them off big time every time they enter your country.
When will these guys learn that data is not the same as intelligence?
Mine is the one with the shiny new degree from the UFO (sorry, couldn't miss the chance to hijack that acronym for the University of the Fucking Obvious)
Too true: "Adding hay does not make finding needles easier" is one of my favourite sayings when discussing pattern recognition. The key to successfully finding things is in reducing data by knowing exactly how to obtain all relevant information rather than just flinging more data at the problem.
One of the coolest galaxies
just got even cooler! I just downloaded the paper and it is really fascinating. I am surprised to see such a well-defined spiral inside the galaxy.

Re: There are many ways to skin a cat...
Many astronomers now say the moon is not really a satellite of earth (hence "That is not a moon" ;-) ), because it is not many orders of magnitude lighter than the Earth. The Earth-Moon system is a double planet (much like Pluto and Charon is properly called a double dwarf planet).
Most moons formed in orbit around their planet, as mini solar systems (and can have a strikingly different composition from their parent planet, and even each other, depending on the distance to the planet). Some, like Phobos and Deimos of Mars, were probably captured asteroids.
