elcome to the


...the largest organization of planetarium professionals in the world.

24 May 2019 ALERT: We are sad to report that within the past two days a number of IPS members have received messages with Subject line "Summit Invitation Letter.PDF", a button that says "Download Attachments", and a "Learn More" link. They are intended to seem like they are from IPS, but are actually from a yahoo.com.ar address. We hope that nobody was duped by this, since at best it was spam and at worst phishing or virus attack attempt. In general, avoid clicking any link or responding to any email address without knowing that it's not bogus. Official IPS emails are only from an ips-planetarium.org address. We are reporting this incident to the IPS website service provider and Yahoo.

Nominations for 2020 IPS Awards and Fellows due July 1. See Awardees and Fellows page for more information.

The next IPS conference:
18–25 June 2020
in Edmonton, Alberta, Canada.World of Science, Edmonton
See the Conference web pages.
