Social media users were all left making the same comment when an 'awesome' image of the International Space Station (ISS) was shared online.
Over on Reddit, one user named @Correct_Presence_936 shared a photo of the ISS, explaining: "I Captured the ISS During the Day; My Sharpest Image to Date."
The impressive photo shows the ISS in the sky, and is remarkably clear, considering how hard the ISS is to photograph.

BBC Sky at Night Magazine explains that it can be so difficult to capture the ISS because it moves at a speed of 28,000km/h (17,500mph) in low Earth orbit - which is pretty fast.
Over on Reddit, people were blown away that the user had been able to get such a decent shot.
"Blows my mind that people can just do this as a hobby. Awesome shot," one wrote, while another said: "Getting a photo this clear of something so far and so FAST with HAND TRACKING is just incredible."
And a third added: "It blows my mind that regular folks have the skill to pull it off. Bravo."

Others made similar comments, pointing out how fast the ISS travels.
One said: "I've also taken photos of it (not this good), and I'll tell you, when you're swinging a telescope around by hand to track this thing across the sky, it does not feel like it's hanging there at all.

"Quite the opposite, it's absolutely mind blowing how something so huge can be positively hauling a**."
Another commenter wrote: "It is falling due to gravity, but it's moving so fast (about 17,000 mph) that it keeps missing Earth."
Someone else added: "It goes by fairly quick! Like a slightly slower shooting star. Was super fun staring into the sky waiting for it to go overhead."
The ISS is in constant motion and is always falling, however, it never crashes into Earth.

Space.com explains: "It sounds miraculous, but it is not a paradox or magic, simply the result of good old fashioned physics.
"It all comes down to the International Space Station's orbital velocity, its height above the ground, and the rate at which it is falling under gravity."
In a period of 24 hours, the ISS makes 16 orbits of Earth and travels through 16 sunrises and sunsets. Meanwhile, the area inside the space station is actually bigger than a six-bedroom house.
According to NASA, it features six sleeping areas, two bathrooms, a gym and a huge, 360-degree bay window.
