ROUND 1

Hubble Space Telescope13.1 m

Answer: the Hubble Space Telescope measures 13.1 m (length / span), which is 1.1× as big as the reference, a Tyrannosaurus rex at 12.3 m.

Hubble is roughly the size of a school bus, which is exactly what the Shuttle’s cargo bay was built to hold.

Common miss: players tend to compress the Hubble Space Telescope when it sits beside a Tyrannosaurus rex — big things get squeezed, small familiar things get stretched.
