[edit] Photograph
Why is a photograph taken by Janssen of a dirigible needed in this article? It's an interesting old picture, but does it tell the reader much about Janssen? -- Astrochemist 12:37, 12 May 2007 (UTC)
[edit] Discovery of helium: 8th or 18th of August ?
I notice that despite Janssen's priority, Encyclopaedia Britannica 1911 wants to give credit for the discovery of helium to Norman Lockyer, an Englishman by coincidence. *cough* Preumably that's why the 1911 text made no mention of helium in Janssen's entry, even though it covered the 1868 Indian eclipse expidition fairly well. -- John Owens (talk) 2005 July 7 03:48 (UTC)
When was helium first discovered ? Helium#Discoveries says 1868 August 18. Pierre Jules César Janssen says August 8. Other descriptions of the events seem to be the same on the two wikipages, but one of them is wrong. Can someone in the know fix this, please ? Thanks. -- PFHLai 06:12, 2005 August 17 (UTC)
- All we need is the exact date of the solar eclipse in India of that year. I found this page, that seems to indicate that August 18 is the correct date. Awolf002 13:39, 17 August 2005 (UTC)

- Great ! Thank you ! Tomorrow is the anniversary, eh ! I'll fix the article accordingly. -- PFHLai 17:00, 2005 August 17 (UTC)
[edit] Simpsons Reference
If people want to put it in, let them, and leave it there. It doesn't matter if it's considered 'trivial'. —Preceding unsigned comment added by 124.171.199.225 (talk) 12:56, 28 October 2007 (UTC)
[edit] Some additions
Today I split the Janssen article into sections, added some new pictures, and put in some additional references. Can someone write more about Janssen's early life or on his contributions to solar photography? - Astrochemist 17:57, 18 August 2007 (UTC)
