I wrote the following email to the NSF webmaster:

Hi,

You have some nice graphics of Gamma Ray Bursts, for instance http://www.nsf.gov/news/news_images.jsp?cntn_id=104440&org=NSF.

I'm working on that Wikipedia article: http://en.wikipedia.org/wiki/Gamma_ray_burst

Could you possibly identify any suitable graphics from your site with Public Domain or CC-BY licensure so we can use them? Thank you!

Best regards, Jonathan

Thus, this image is in the public domain. - Jehochman Talk 02:00, 1 December 2007 (UTC)
