WebAR means the experience launches from a browser route. Users can read a guide page, tap Start Sky AR, and grant permissions only when they are ready.
No-download AR stargazing
WebAR Stargazing App You Can Use in Your Browser
NightSky AR is designed for mobile browsers over HTTPS. It gives users a no-download way to launch an AR constellation viewer from useful astronomy pages.
Camera and motion sensors
The viewer uses the environment-facing camera, device orientation, and manual heading adjustment to place constellation overlays on the sky.
Built for discovery
The SEO pages answer common sky questions. The AR route is for action: comparing guide stars, constellation lines, and compass directions outside.
Frequently asked questions
Short answers for common skywatching questions before opening the AR viewer.
Does WebAR require an app store download?
No. NightSky AR runs from a supported mobile browser over HTTPS and asks for permissions only after the start tap.
Why does the AR page stay noindex?
The AR page is a functional camera screen. Search traffic should land on crawlable guide pages with useful text and then continue into AR.
What permissions does the viewer use?
The viewer uses camera, motion or orientation access, and location so it can align the sky map with the device and local horizon.
