A day on Venus lasts longer than its year: the planet takes about 243 Earth days to spin once and only 225 to circle the Sun. The Andromeda galaxy, about 2.5 million light years away, is one of the most distant things you can see without a telescope. Both are in this grid with 33 other space words, from SPUTNIK, the first satellite in 1957, to the PULSAR, first detected by Jocelyn Bell Burnell in 1967. ASTRONAUT and COSMONAUT share their last four letters, so watch which one you circle.
