   The astronomy syllabus now follows the senior IOAA syllabus

   The astronomy syllabus used to be transcribed from the Junior IOAA syllabus. It now follows the senior IOAA syllabus, because the OSN guide says OSN astronomy follows the IOAA syllabus.

   The senior syllabus has no "space sciences" section or "cosmonautics" topic, so both are gone. The topics exoplanets and space-exploration moved to the sections where the senior syllabus lists them. Topic ids that existed before were kept, so materials, editorials and your planner are unaffected.

   Each syllabus topic now says where it comes from

   Each syllabus page now opens with a Where this comes from block. It names every source, who issues it, the edition, its official language, when the topic list was last compared with it, and how far that comparison went.

   Every topic carries a label showing which syllabuses list it. For physics we added the IPhO syllabus next to the OSN guide: topics only the IPhO lists are labelled as such, and are not confirmed in the OSN guide. For informatics we added the IOI syllabus, and for astronomy the 2025 OSN guide, which says astronomy follows the IOAA syllabus.

   Nothing about the study planner or the quiz bank changed. They still use only the OSN topics.
