both the Here for comparison is the full data (publicly available, thanks NASA!!) over the lifetime ofthe twin Voyager probes for the cosmic ray instrument.









I think this figure is even more remarkable than the 1-year subset shown on APOD, as it gives you a flavor for both the

of the Voyager mission, and the magnitude of the discovery.





I frequently think how the seemingly menial data we collect today might be used in the future, and this figure is a grand example. If we want to discover the

The upturn (highlighted by the red bar) isnoticeable from 2011 onwards. Sinusoidal modulations, measured by both spacecraft, seem to occur on roughly an 11 year cycle subtle things, things that take a long time to find, or only change noticeably on timescales longer than a human lifespan, then. This is our investment in the future of astronomy, and why you mind your p's and q's when reporting and storing your observations.
