Understand what Astro Corner can publish to the open web, how public astronomy reaches Discover/search engines and which privacy choices remain under your control.
Astro Corner can make genuinely public astronomy useful outside a signed-in social feed. Public pages may appear in Discover, XML sitemaps, normal search engines and web-search assistants, while private/member/friends-only records remain governed by their original audience rules.
What Discover shows
Discover is a public entry point for astronomy records that are eligible to be seen without an Astro Corner account. Depending on their visibility, this can include profiles, posts, images, communities, Guides, observations, observing nights, projects, events, equipment reference pages and other supported public records.
Discover does not turn a restricted record public. It only links to records that already pass the public-content checks for that type.
Search engines and AI-powered web search
Astro Corner publishes an XML sitemap and can notify participating search engines about changed public URLs. Search crawlers such as Google, Bing and web-search assistants can then discover the same public pages any ordinary visitor can open.
Search ranking and whether an external service chooses to show a page are controlled by that service, not by Astro Corner.
Public, unlisted and restricted
Public is the correct choice when you are comfortable with a record being openly discoverable. Unlisted is intended for direct-link sharing without deliberate normal discovery where that visibility exists. Friends, members and private/Only Me audiences are not submitted as public content.
Public Passport, Statistics and recaps
Passport, Statistics and yearly recap have their own public-sharing choices where available. Enabling one of those public summaries does not expose the source records beyond their own visibility settings.
Generated share cards summarise the permitted public page; they should never be treated as a way to bypass the underlying privacy decision.
Review before publishing
Before publishing an observing report, photograph or society page, check it for information you would not want indexed outside Astro Corner—especially exact home locations, private contact details or details about another person who has not chosen to publish them.
