Hey neighbor, it's World Space Week!
Space is a big, lonely place, so it's nice to know we have neighbors. The pictured Andromeda galaxy is our Milky Way's closest neighbor—right next door at 2.5 million light-years away. Our cordial relationship with Andromeda goes back about 10 billion years to when both galaxies were still forming. But trouble is brewing: Andromeda is on a collision course with the Milky Way, due for impact in 4 billion years. This neighborhood's about to get rough…
Sometime in the 4 billion years we have left (preferably this World Space Week, October 4-10), we encourage you to turn your attention to the stars, whether you're in the countryside, a planetarium, or your backyard. World Space Week's 2021 theme is 'Women in Space'—and it's also the theme of today's quiz. How much do you know about the final frontier's famous females?
