I don't have access to specific historical events like that. You can try searching online for information about specific astronomical events that may have occurred on October 17, 2008.

Here are some good places to look:

* NASA's website: They often have archives of past events.

* Space.com: This website covers a wide range of space-related news and information.

* Astronomy websites: Sites like Sky & Telescope or Astronomy Magazine often have archives of past events.

* General news archives: Websites like the New York Times or BBC News may have archives of past news articles.

Good luck in your search!
