Let's face it, Scott Kelly's Twitter account gives everyone on earth FOMO.
And his recent tweet just added fuel to the fire.
Wishing goodnight to all his followers on earth, Kelly posted an epic image of the sun as seen on day 178 of his year-long stint in space.
The stunning blue horizon is marked by one single shining circle, the sun, perfectly positioned on the linear blue haze. Simply gorgeous.
We only wish we had something equally stunning to tweet back from earth.
And if Kelly's images are not enough, check out these incredible pictures from the Astronomy Photographer of the Year Awards.
