What is Big Think?  

We are Big Idea Hunters…

We live in a time of information abundance, which far too many of us see as information overload. With the sum total of human knowledge, past and present, at our fingertips, we’re faced with a crisis of attention: which ideas should we engage with, and why? Big Think is an evolving roadmap to the best thinking on the planet — the ideas that can help you think flexibly and act decisively in a multivariate world.

A word about Big Ideas and Themes — The architecture of Big Think

Big ideas are lenses for envisioning the future. Every article and video on bigthink.com and on our learning platforms is based on an emerging “big idea” that is significant, widely relevant, and actionable. We’re sifting the noise for the questions and insights that have the power to change all of our lives, for decades to come. For example, reverse-engineering is a big idea in that the concept is increasingly useful across multiple disciplines, from education to nanotechnology.

Themes are the seven broad umbrellas under which we organize the hundreds of big ideas that populate Big Think. They include New World Order, Earth and Beyond, 21st Century Living, Going Mental, Extreme Biology, Power and Influence, and Inventing the Future.

Cassini Confirms Existence Of Water Ice On Saturn

September 4, 2013, 5:00 PM

What's the Latest Development?

For the first time, NASA's Cassini spacecraft has produced near-infrared images showing evidence of water ice on Saturn, made visible due to the power of a massive storm that encircled the planet in 2010-2011. The ice appears in the upper atmosphere, which consists primarily of frozen ammonia, and is presumed to have come from an invisible lower atmospheric layer made up of ammonium hydrosulfide and water.

What's the Big Idea?

Scientists have long known that Saturn's moons contained water ice, but they didn't expect to see it on the planet itself in the quantities revealed by Cassini's images. Studies of the superstorm showed that it behaved very similarly to much smaller storms on Earth, in which air and water vapor are pushed up to create tall thunderstorm clouds. In a paper to be published in a forthcoming issue of Icarus, co-author and University of Wisconsin-Madison researcher Kevin Baines says that Cassini's discovery "shows that Saturn [storms] can dredge up material from more than 100 miles [160 kilometers]...It demonstrates in a very real sense that typically demure-looking Saturn can be just as explosive or even more so than typically stormy Jupiter."
