NOVA | Earth From Space

Watch Earth from Space on PBS. See more from NOVA.

  • Earth from Space takes you on an epic quest to discover the invisible forces and processes that sustain life on our planet and, for the first time, see them in action in their natural environment in vivid detail. These truly unique images will explore the deepest mysteries of its existence, raising profound questions and challenging the old assumptions of how Earth's system works.

  • Great 2 hour program!  Monte
  • Wow! --> Best 1 hour and 53 minutes I have spent learning about our plant! Highly recommend, if you are interested it understanding how our environment works in detail. I do not think you will regret spending the time... You will be surprised and know much more than a lot of politicians that are representing us...

Program Description

"Earth From Space" is a groundbreaking two-hour special that reveals a spectacular new space-based vision of our planet. Produced in extensive consultation with NASA scientists, NOVA takes data from earth-observing satellites and transforms it into dazzling visual sequences, each one exposing the intricate and surprising web of forces that sustains life on earth.

Viewers witness how dust blown from the Sahara fertilizes the Amazon; how a vast submarine "waterfall" off Antarctica helps drive ocean currents around the world; and how the Sun's heating up of the southern Atlantic gives birth to a colossally powerful hurricane. From the microscopic world of water molecules vaporizing over the ocean to the magnetic field that is bigger than Earth itself, the show reveals the astonishing beauty and complexity of our dynamic planet.

The Uses of Satellite Imagery

Images from near-Earth orbit help us with everything from weather forecasting and disaster management to archeology.

Global Weather Machine

What are the primary forces behind what we call weather, and how does El NiƱo take over the global weather system?

Glacier Hazards From Space

View satellite images of glaciers that have wreaked havoc—or might soon.

Inside the Jet Stream

What exactly is this high, eastward-flowing wind we hear about on weather reports? Find out in this interactive.

Hotter Oceans, Fiercer Storms

In this audio slide show, examine the link between rising sea surface temperature and more intense storms.

What Does the Earth Sound Like?

Twin satellites probing the Earth's radiation belts return the clearest recordings yet of a "chorus" of radio waves.

Hurricanes and Climate Change

Why climate change is making hurricanes more dangerous.

A climate scientist suggests that rapid warming in the Arctic helped create October's "superstorm."

Hurricane Power

Your average hurricane releases enough energy to power the world 200 times over. Go figure.

Journey back to the beginning of everything: the universe, Earth and life itself.

The Sun Lab

Research solar storms using images from NASA telescopes; share your work; and find out about careers in science.
