Earth selfies are su?t tinh khi xem phim khiêu damso two centuries ago.
If you want to impress us, you've got to take your picture from space.
Whether they're outside performing maintenance on the International Space Station during a spacewalk or hanging out inside the flight deck, astronauts prove time and time again that the selfies we take on Earth are wack.
Apollo 11 astronaut Buzz Aldrin kicked off the space selfie trend back in the day but it's continued on decades later. Nearly every astronaut that travels to orbit these days beams home at least one rad selfie.
Here are our absolute favorite space selfies sent home from the void.
Buzz Aldrin

While performing a spacewalk on his Gemini 12 mission in 1966, the astronaut turned the camera back on himself and got an incredible picture of himself floating through space with Earth in the background.
Now astronauts always document their spacewalks -- a tradition that Aldrin loves to remind people that he started.
Mark Vande Hei

According to NASA, he and astronaut Scott Tingle spent 7 hours and 24 minutes outside of the station working on the Canadarm2 robotic arm.
Ricky Arnold

He and astronaut Drew Feustel were outside of space station working on the station's cooling system during the hours-long walk in space.
Alexander Gerst

Michael Collins

NASA used the Gemini program to test gear and train astronauts while they were orbiting Earth in order to prepare for future flights to the moon.
Scott Kelly

Before Kelly retired from NASA in 2016, he flew to space six times.
This favorite selfie was taken during his year-long mission to the space station, designed to help NASA figure out best serve people living and working in space for long spells of time.
The light you see reflecting off his face in the selfie is the glow of the Earth below.
NASA's Newest Recruits

It was only fitting, then, that NASA invite the largest group in its history to train to be future astronauts. This picture was taken while the group was at Ellington Field getting fitted for flight suits not long after they were selected in 2017.
Akihiko Hoshide

While working on the space station in 2012, Japan's Akihiko Hoshide managed to capture the sunlit world in the reflection of his visor.
And right behind him? The sun.
