The only thing is, not everyone’s convinced by the stunning snaps. You’ve guessed it: the flat Earthers are not having it.
Jessica Meir is an astronaut who’s currently loving life aboard the ISS, the space station orbiting Earth that is a joint project between five space agencies: NASA (USA), Roscosmos (Russia), JAXA (Japan), ESA (Europe) and CSA (Canada).
The ISS orbits Earth at a height of around 250 miles (400km), meaning Meir has been getting some pretty incredible views.
Sharing the photos of the ‘ever-changing skyline’ she gets to witness, Meir tweeted: “The first orientation may make more sense to you, but to me this is the ever-changing skyline on @Space_Station (photo 3). Perspective.
“The constant traffic of visiting vehicles makes for diverse vistas. Now the #Canadarm2 keeps #Cygnus company after @SpaceX #Dragon’s departure.”
While many social media users thanked Meir for sharing the ‘beautiful’ images, some decided they simply weren’t satisfied.
One tweeted: “So from 400km above the earth you can view the whole round earth? Yeah very believable.”
Someone else said: “Nice try with the fish eye, but it’s flat.”
A third wrote: “Yes. That’s fish eye lens. Make earth looks like round. Actually, the earth is Flat!”
Another asked dubiously: “Why do you guys always use fish eye lenses?”
If you’re one of the non-believers, NASA has broken it all down for you in a handy post on its website titled ‘How Do We Know Earth Is Round?’.
It reads: “Humans have known that Earth is round for more than 2,000 years! The ancient Greeks measured shadows during summer solstice and also calculated Earth’s circumference. They used positions of stars and constellations to estimate distances on Earth.
“They could even see the planet’s round shadow on the moon during a lunar eclipse. (We still can see this during lunar eclipses.)
“Today, scientists use geodesy, which is the science of measuring Earth’s shape, gravity and rotation. Geodesy provides accurate measurements that show Earth is round. With GPS and other satellites, scientists can measure Earth’s size and shape to within a centimeter. Pictures from space also show Earth is round like the moon.
“Even though our planet is a sphere, it is not a perfect sphere. Because of the force caused when Earth rotates, the North and South Poles are slightly flat. Earth’s rotation, wobbly motion and other forces are making the planet change shape very slowly, but it is still round.”
So, there you have it.
