Are there plans to christen a nearby nebula after Steve Irwin?
Please explain:
- (Hen-1357) -- what classification system is this?
This means the 1357th object in Karl Henize's 3rd catalog. It's also known as He3-1357. --DrMattB
- as large as 130 solar systems - OUR solar system, or any?
Our solar system. --DrMattB
- as big as a dime - please do not use examples that only North American readers can understand.

Hen-1357 refers to the 1357th object in Karl Henize's 3rd list of stars showing emission-line features. "130 solar systems" is a comparison to OUR solar system. Good idea not to use the "dime" comparison. DrMattB (talk) 16:10, 31 July 2009 (UTC)
18,000 years ago
Shouldn't we point out that all this took place 18,000 years ago - it's just now that the light reached us ? -- Beardo 02:58, 22 January 2007 (UTC)
- The whole point of this article seems to be the claim that it didn't happen 18,000 years ago, but rather in 1987. This is explicitly what the DYK "hook" says. Is that simply incorrect? -Dmz5*Edits**Talk* 03:05, 22 January 2007 (UTC)
- Logic and science dictate that it could not have happened in the last century. Xiner (talk, email) 03:19, 22 January 2007 (UTC)
- I know, you are right. So, what's the deal then?-Dmz5*Edits**Talk* 03:23, 22 January 2007 (UTC)
- Logic and science dictate that it could not have happened in the last century. Xiner (talk, email) 03:19, 22 January 2007 (UTC)
- The point is that we can observe it for scientific examination at a very young age. From the perspective of earth, it is the youngest known observable PN. WilliamKF 01:32, 24 January 2007 (UTC)
Latest Info
I'm adding a lot more information, based on the papers that have come out since the HST observations. DrMattB (talk) 16:12, 31 July 2009 (UTC)
BTW, the photo you see appeared on the cover of the issue of Nature that contained Bobrowsky's definitive paper on this object.[1]
XKCD
This was referred to in http://xkcd.com/847/ . Should this be added to the article? Perhaps a In Popular culture section? Azrich (talk) 17:55, 14 January 2011 (UTC)
- No. Stop doing that. —Preceding unsigned comment added by 96.224.70.156 (talk) 18:41, 14 January 2011 (UTC)

The Stingray nebula is fading
A recent study has found that in the two last decades, the Stingray nebula has been extinguished (the oxygen emission, dimmed in brightness by a factor of nearly a thousand between 1996 and 2016).

- Template:Re Are the usage rights for these images compatible with Wikimedia Commons? The fast dimming is the most interesting thing about this nebula, so we should add these images to the article if we can. — UnladenSwallow (talk) 18:12, 13 May 2021 (UTC)
- Template:Re Yes indeed. I have just uploaded the photo to commons as File:Fading Stingray.jpg. Alexcalamaro (talk) 06:18, 14 May 2021 (UTC)
- Template:Re Thank you! I have added the image to the article. I have also moved things around and made some edits to make the article more clear. Still not entirely happy with it, especially the cryptic mention of "gas outflow collimation" in the lead—no idea what that means. — UnladenSwallow (talk) 18:22, 15 May 2021 (UTC)
- Template:Re I noticed your tag and tried to un-cryptic that sentence; is it more comprehensible now? (Also, African or European remains unresolved, please clarify.) Wikignome Wintergreentalk 17:36, 25 May 2021 (UTC)
