Did you know?

galaxy
Webb photographed thousands of galaxies in a sky patch that could hide behind a grain of sand held at arm's length.
planet
On Venus a single day lasts longer than its year, because it spins slower than it circles the Sun.
rocket
A rocket in orbit is still falling toward Earth, but moves sideways fast enough to keep missing the ground.
gravity
On the Moon, gravity is so weak that an astronaut who weighs 180 pounds on Earth would weigh just 30 pounds.
eclipse
A total solar eclipse works because the Moon and Sun look the same size from Earth by sheer coincidence.
asteroid
Some asteroids have their own moons, turning a small rocky object into the center of an even smaller orbital system.
universe
Looking farther into the universe also means looking backward in time, because distant light takes years to reach us.
supernova
A supernova can scatter elements forged inside a star, spreading ingredients that later become parts of planets and living things.
telescope
The James Webb telescope is so sensitive it could detect a bumblebee's body heat from as far away as the Moon.
astronaut
Astronauts can grow up to two inches taller in space, because without gravity their spine gently stretches out.
nebula
A nebula can glow without making its own starlight, reflecting nearby stars like cosmic dust caught in a spotlight.
spacesuit
Astronaut gloves are pressurized, so bending a finger takes effort; working in space can feel like squeezing an inflated balloon.
constellation
Stars in a constellation can lie very different distances away, appearing neighbors only because we see them from Earth.
satellite
The oldest human-made satellite still in orbit is Vanguard 1, launched in 1958 and silent but circling to this day.
meteor
Most meteors that streak across the sky are no bigger than a grain of sand, burning up high in the air.

That's one small step for a man, one giant leap for mankind.
