TIME TO BUILD
How long does it take to build Tales of the Space Age?
A starting point for planning your build. Times for each experience level are editorial estimates, not measurements submitted by HowLongToBuild users.
Editorial model estimate · no verified measured building time
Intermediate
≈ 2 h 45 minSuggested range1 h 45 min – 4 hExperienced
≈ 2 hSuggested range1 h 15 min – 3 hBased on one person building the set for the first time, following the original instructions and using numbered bags where supplied. Includes normal piece-finding and minor adjustments; excludes long breaks, filming, dismantling and modifications. Sources may use different methods. This range is neither a statistical interval nor a limit: your build may take less or more time.
How we estimate times · sources and method
Four independent compositions, layered backgrounds and small symbols. The three central durations are model-specific editorial assessments. Planning ranges extend approximately from 65% to 145%, rounded to quarter-hours; they are not measured experience-level averages or guaranteed limits.
Sources do not always specify the builder’s experience. The three experience bands are our editorial assessment, based on the complexity of the set and individual accounts where available.

The first black-hole image was presented on 10 April 2019, showing M87’s central object through the Event Horizon Telescope. NASA places the galaxy about fifty-five million light-years away. This was another galaxy, not the Milky Way’s black hole, giving the achievement its location.
Light reveals the outline
Hot gas near the black hole outlines the dark region. The light does not come from inside it.
