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
I received a reply that said, in part: "Any image (like the one in question) credited to the National Science Foundation is in the public domain and can be used freely."
Thus, this image is in the public domain.
