The first entry is always the pin's source. Overall confidence is a weighted average of how firmly each reference supports the start and end times used above; a reference counts half as much for every 180 days older than the newest.
Given as a target, not a fixed date, per the pin description: "…as the world's largest radio telescope. Estimated date.…"
SKAO's[3] own "construction journey" page is the observatory's account of its build-out timeline and the primary source underlying the pin's "estimated" 2030 target for full-array observations, though its content could not be directly retrieved here.
SKAO's[2] own release describes only a partial first-light image from SKA-Low, using just 1,024 of the eventual 131,072 planned antennas, dated 17 March 2025 - a preliminary milestone well short of full observations, consistent with the pin's "estimated" 2030 date for when full observations begin.
Something missing or wrong? Say it in your own words: a link that backs this pin up, a different start or end date and why, or a fact it lacks or gets wrong. The AI checks it against this pin's sources, searches for better ones, and adds any page that backs you up. The pin's own sources still count most.
