I do not have the content of the provided article "Is astronomy a luxury?" from Science (Volume 391, Issue 6792, March 2026), so I cannot create a summary based only on verified facts from it. The available search results do not contain the text of the article or its main findings, statistics or details. The summary would not be factual and verified as required. If you provide the full content of the article, I will prepare a summary according to the instructions.
