Space imagery is a Bing homepage constant, nebulae, launches, the Milky Way, and the space quiz drew huge search interest. Planet records and spaceflight firsts supply most answers, and the hottest-planet question catches almost everyone once.

The hottest-planet trap
Mercury sits closest to the Sun, but Venus is the hottest planet, its dense carbon-dioxide atmosphere traps heat in a runaway greenhouse effect. Jupiter is the largest planet, Mars gets its red colour from iron oxide, and Saturn's rings front the image questions.
Spaceflight firsts
Yuri Gagarin became the first human in space in 1961; Apollo 11 put Neil Armstrong and Buzz Aldrin on the Moon in July 1969. Valentina Tereshkova's 1963 flight, the first woman in space, crosses over from the women's history rounds, and the International Space Station has hosted crews continuously since 2000.
Units and objects
A light-year measures distance, not time, the span light travels in a year, a trap Bing loves. The Sun is a star, the Milky Way is our galaxy, and 'what is a supermoon or blood moon' questions hand off to the lunar side of the quiz.
Answering approach
Planet records and mission dates are fixed, learn the handful above. For anything about current missions or recent launches, search the mission name, because spaceflight news moves quickly.
