Lightyears, that's more like it.

Phenomenal Photo!

BTW, what are those resolutions in ALACU's (astronomical Los Angles County units)? Couldn't resist the urge to stir up trouble. Maybe they should also be presented in Londons or milli-Australias.

IMO your country has and continues to have much to offer the world – especially in the science. Actually for the U.S.A., except for some minor quirks and eccentricities here and there, and perhaps sometimes too over the top patriotism and hype or insular views of the rest of the world – but overall Americans are fair and decent people. The ones I've so far meet seem just like me.
So no, your assumption is wrong. I don't think I have really have any real animosity to the U.S. at all.
Anyway, I'm so sorry to disappoint you, I don't live in the British Isles, England or Europe, but at least now we know about your true xenophobic fears are aim towards.
As the English sometimes say; Cheers my good man….. and thanks for your perspective.

I cannot see any suggestion that anyone is trying to tell you how to spell.

You seem to have a huge animosity towards those of us in the USA and any of our materiel, so if you don't like the TV program, turn off the TV (or should I say Telly).

Your Socialist ranting is one of the reasons we left your country, and attitudes, some 300 years ago, we don't want anypart of it now.

It was probably a huge mistake on our part to get involved with your problems in the early 1900's and the 1940's, we should have let you solve them on your own. Let's pray we don't get involved again.

Right… now I get it…. Americans don't want to adopt the metric system, so therefore they want to tell us how to spell it.
Simple logic still astounds me.
Praise God for the Atlantic and wider Pacific Ocean!

"Kilometer" is not a wrong Americanised (Americanized) spelling of "kilometre" – it is American English (aka AmE, AE, or en-US) for "kilometre".
I live in Ireland. I could go to the local College of Commerce and take a course in American English. There doesn't seem to be much point, though. I've had no problems, so far, understanding any American English I came across….

What a beautiful image, thanks for the link to the original. I downloaded both, the largest JPEG and the largest animation. This is great – the magic of IR photography, letting me peep into the "mysterious Dark Rift"…

Here it is stated under "Style';
"Use standard abbreviations for SI (e.g., m, km, mm) and natural units (e.g., AU, pc, cm). If English units such as inches or pounds per square inch are used, metric equivalents should follow in parentheses."
As to your irrelevant "socialism" brain snap, well the imperial system in science and generally is actually in the significantly small minority. The United States is only one officially resisting the metric system, along with Liberia and Myanmar. Even your scientists (and astronomers) have already seen the light, like the AAS. Sadly, your argument here of isolationism is no longer a practical policy.
Also if you must use imperial measures, the why not give both?

Oh, and finally, the Americanised spelling of "Kilometers" is wrong. It is spelt 'kilometres"? (How arrogant is this? You claim your readers are being dictated too, yet when even the system you don't claim to use is presented, you try and impose the Americanised spelling. on the rest of us. Socialism you reckon?)

"The spatial resolution of NICMOS corresponds to 0.025 light-years at the distance of the galactic core of 26,000 light-years. Hubble reveals details in objects as small as 20 times the size of our own solar system."

This should read;

"The spatial resolution of NICMOS corresponds to 0.0075 parsecs (16,000 A.U. [if you must]) at the distance of the galactic core of 8 kpc (kiloparsecs). Hubble reveals details in objects as small as 20 times the size of our own solar system"

AAAAAAhhhh! (takes a deep breath in) Now THIS is Astronomy.
