What causes the dark radial stripes? Blocked by something in the sky? Downtime?
I know Elite Dangerous has similar artifacts showing small radial areas of the galaxy that our telescopes have surveyed (but it's lines of stars rather than lines of darkness)
- jwuphysics 5y agoMy best guess is that those are near very bright foreground stars, which cause artifacts in the corresponding imaging survey. DESI Legacy Imaging Surveys is used to pre-select targets for spectroscopic observations. If you go to legacysurvey.org/viewer you can see some of the bright stars and the kinds of issues they can cause.
