This may be a station or a sit-down test.   It may also be done as a powerpoint or inside a planetarium, but these are far less common.  Teams may be viewing any combination of models, pictures, diagrams/charts, or recorded/written descriptions. They will then be asked to answer questions (multiple choice, fill in the blank, short answer, etc), label diagrams, make graphs, etc. related to the information. Topic for 2023 tournament season is an understanding of Stellar Evolution & Variability.


Each team may bring one of the following options containing information in any form and from any source:
i. two three-ring binders;
ii. a computer/tablet and a three-ring binder; or,
iii. two computers/tablets, of any kind.

If three-ring binders are used they may be of any size and the information contained should be attached using the available rings. The information or pages may be removed during the event. Sheet protectors and laminated sheets are allowed.

Each team may bring two stand-alone calculators of any type to use during the event. If the participants are using a computer/tablet they may use a calculator app or other program on their device in place of a stand-alone calculator.  No Internet access is allowed during any part of this event. Participants using computers/tablets as a resource should have all information stored so that it is available to them off-line.


High score wins. Questions are worth a pre-assigned number of points. Predetermined questions will be used to break ties.

Common Mistakes:



-Contact Community Colleges and Universities near you to see what special events they are hosting. Many have planetariums or host stargazing nights, or will take you on a tour of their facility.
