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—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 on a trip to the countryside, the 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?

嘿，邻居，这是世界太空周！

太空是一个又大又孤独的地方，所以知道我们有邻居很好。照片中的仙女座星系是我们银河系最近的邻居，距离我们250万光年远。我们与仙女座星系的亲密关系可以追溯到大约100亿年前，当时两个星系都还在形成。但麻烦正在酝酿：仙女座正在与银河系发生碰撞，预计将在40亿年后发生碰撞。这附近就要闹了…

在我们剩下的40亿年中的某个时候（最好是10月4日至10日的世界空间周），我们鼓励你将注意力转向星星，无论是去乡村、天文馆还是你的后院。2021年世界空间周的主题是“太空中的女性”——这也是今天测验的主题。你对《最后的边疆》的著名女性了解多少？
