Astronauts have the privilege of seeing the wonders of earth and space from an entirely different perspective. Now, thanks to Twitter, we are able to follow their adventures and insights as they post photos and thoughts to the social media platform.
There are only three NASA astronauts currently in space, but those who have returned to earth continue to give real time updates and behind the scenes photos about the world of space.
Here are eight astronauts to follow on Twitter:
1. Reid Wiseman
According to his profile, Wiseman is currently living on the ISS in the low earth orbit.
Just this morning he tweeted a photo of Auckland, saying, "Two volcanoes peek through the morning clouds near Auckland, New Zealand."
