Cosmic Journeys

Scientists map the surface of the moon and piece together its history to determine how it formed and learn more about Earth's origins in the process.

Scientists probe the sun to learn more about coronal mass ejections, violent periodic outbursts that disrupt Earth's electrical systems.

Exploring the various aspects of the cosmos.

From the Cassini spacecraft comes one of the greatest photographic collections. Scientists are using it to uncover a trail of clues pointing to the energy sources and complex chemistry needed to spawn life.

Our Milky Way Galaxy is thought to harbor millions of black holes, the ultra dense remnants of dead stars. But now, in the universe far beyond our galaxy, there's evidence of something far more ominous. A breed of black holes that has reached incomprehensible size and destructive power. Just how large, and violent, and strange can they get?

Scientists look out deep into space hoping to measure the size of the universe based on the relatively miniscule portion of space observable from Earth.
