An astronomer has captured an image showing both the International Space Station (ISS) and China's Tianhe-1 space station in the sky at the same time.
Spotting the ISS whizzing overhead is not unusual; it orbits Earth every 90 minutes. According to NASA, the station is the third-brightest object in the sky and can be seen with the naked eye as the sun reflects off of it.
There's even an interactive map to help sky watchers determine when the ISS will fly overhead next so they know when to look up.
