This is the Internatinal Space Station, or ISS. It can usualy be seen at night time flying across the sky at certain days. Thats because it is in orbet with Earth. Just like the other probes that are in orbet taking pictures of Earth and using wireless intenas to send those pictures back to Earth, it’s kinda cool once you get to understand more about it.
