The first photo of Jupiter and its moons
“Jupiter and its four planet-size moons, called the Galilean satellites, were photographed in early March 1979 by Voyager 1 and assembled into this collage,” according to NASA. Although they’re not to scale, they’re in their relative positions.
The first photo of the Cat’s Eye Nebula
A planetary nebula forms when stars similar to our sun release their outer layers of gas, which form bright nebulae, according to NASA. Here is the first photographic image of the Cat’s Eye Nebula, taken by the Hubble Space Telescope in 1994.
The first time a plane broke the sound barrier
The reason this photo looks unreal is that what it’s capturing had never ever been captured on film before: It’s the moment a Navy jet fighter plane crashed through the sound barrier. As the plane accelerated towards the speed of sound, shock waves caused a cloud to form, which the plane broke through upon reaching the speed of sound, according to the Acoustics Graduate Program at Penn State University.
