Scientists keep finding new, exotic worlds.

"You're always finding things you haven't seen before."

Boom.

Get ready.

There are trillions of planets out there. Some almost certainly contain oceans.

The space race, renewed.

High above the Martian desert.

Scenes from space exploration.

The most powerful rocket on Earth.

"It is incredibly exciting to know that everything is going to be rewritten."

A historic deep space mission.

"It's literally a one-shot thing."

Fly-by photos from the historic deep space mission.

"You need to know what's coming."

"It is absolutely mind blowing."

The return to the moon.

"It's a great pickup truck. I'm glad we built it. And I'm ready to fly."

A galactic enigma.

"We haven't found them all."

"We could be meters away from discovering our closest planetary neighbors."

"It’s an extraordinary result."

Avoiding a close call.

A strange world in an even stranger universe.

"It's the equivalent of getting front row seats at a fireworks show."
