telescopeFind to reveal
The James Webb telescope is so sensitive it could detect a bumblebee's body heat from as far away as the Moon.
astronautFind to reveal
Astronauts can grow up to two inches taller in space, because without gravity their spine gently stretches out.
asteroidFind to reveal
Some asteroids have their own moons, turning a small rocky object into the center of an even smaller orbital system.
universeFind to reveal
Looking farther into the universe also means looking backward in time, because distant light takes years to reach us.
gravityFind to reveal
On the Moon, gravity is so weak that an astronaut who weighs 180 pounds on Earth would weigh just 30 pounds.
eclipseFind to reveal
A total solar eclipse works because the Moon and Sun look the same size from Earth by sheer coincidence.
galaxyFind to reveal
Webb photographed thousands of galaxies in a sky patch that could hide behind a grain of sand held at arm's length.
planetFind to reveal
On Venus a single day lasts longer than its year, because it spins slower than it circles the Sun.

The car in deep space
In February 2018, from Kennedy Space Center in Florida, a powerful new rocket lifted off carrying an unusual passenger: a cherry-red sports car with a mannequin in a spacesuit buckled in the driver's seat. The car was a test weight, chosen instead of dull concrete blocks, and it carried a small plaque and a copy of a favorite science fiction novel. Cameras beamed back images of the dummy, nicknamed Starman, cruising past Earth with the planet glowing blue behind him. The car is now in orbit around the Sun, looping out toward Mars and back. Calculations suggest it could keep circling for a very long time, though its distant future is uncertain, a strange and cheerful monument to human curiosity.
That's one small step for [a] man, one giant leap for mankind.
Neil Armstrong

The photo that changed Earth
On Christmas Eve in 1968, three astronauts circling the Moon became the first people to see Earth rise over another world. As their craft came around the far side, the planet appeared above the gray horizon, a small blue marble wrapped in white clouds, alone in the black. William Anders loaded color film and took the photograph now called Earthrise. Back home the image stunned millions, showing the whole world without borders, fragile and beautiful in the dark. Many people credit that single picture with sparking the modern movement to protect the environment. The crew had flown to study the Moon and ended up rediscovering Earth.
The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.
