Hackers Forced Announcement of 10th Planet Find
JCY2K writes "According to The Inquirer, hackers gained access to the secure server where the data about the new planet was being held and threatened to reveal it. Evidently the discoverers have been withholding this information from the public since 2003 while they waited for full analysis."
This claim has been extensively discussed in the Minor Planet Mailing List, in particular in this thread, where the "hacker" tells the whole story.
