first Foursquare check-in from space is now using his exhibitionist skills on Twitter to share some amazing images of earth. Covering everything from the view of our blue planet outside of the Cupola of the International Space Station, to a night view of the Nile river, or morning breaking over the Andes -- it's pretty surreal stuff and definitely puts your tweets from last night's bar-hopping to shame. We're also glad to see NASA's presence on Twitter be slightly more uplifting than the long, agonizing death of the Mars Phoenix rover. To view some of the shots in question, see the gallery below, or hit the link to Douglas H. Wheelock's (a.k.a @Astro_Wheels) Twitter account to take it all in. Oh and we should also mention he accepts requests, so if there's something you really want to see let him know.
