We are the legacy of 15 billion years of cosmic evolution.
We have a choice: We can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction.

Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.

The very first clip of COSMOS—this is where it all began. A voyage from the shores of Earth's oceans to the infinite expanses of the Milky Way, Andromeda, and beyond.
Thank you, Carl, for taking us on this journey. We remain forever in your debt.

Albert Einstein died on this day, April 18, 1955.
It is incredible to hear Albert Einstein explain his famous formula, E=mc².

"There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known." - Carl Sagan

What is the most spook-tacular nebula in the galaxy?
One contender is LDN 43, which bears an astonishing resemblance to a vast cosmic bat flying amongst the stars on a dark Halloween night.

This dim and distant world is the farthest planet from the Sun, about 30 times farther away than planet Earth.
Details of the complex ring system are seen here for the first time since Neptune was visited by the Voyager 2 spacecraft in August 1989.
