Did you know that you can see the International Space Station (ISS) from Earth with your naked eyes? My husband told me that he’d seen it fly by one night. I don’t know why it surprised me exactly. I remember learning as a kid that it was possible to see Sputnik with binoculars and it’s only a fraction of the size of the ISS. I’m not sure why I never looked for the ISS before but sure enough it is quite visible and really bright.
There are both apps and websites to help figure out when and where it’s visible (along with a lot of other interesting stuff). Here are links to a few of them.
