The astrophysicist Mario Livio spent 24 years at the Space Telescope Science Institute working with the Hubble Telescope, which has revealed the reality and beauty of the Universe to scientists and citizens in whole new ways. The Hubble’s successor, the James Webb Telescope, will become fully operational in 2022, and will further some of the questions about the early formation of the Universe and the origins of life to which Mario Livio has been devoted. Krista spoke with him in 2010, and this conversation has become an On Being Classic, imparting a thrilling sense of all we are learning about the cosmos in this generation in time, our terrible earthly woes notwithstanding. Also: how scientific advance always meets recurrent mystery, from the emergence of life in the Universe to the very heart of mathematics and the puzzle of dark matter and dark energy.

Here are some experiences to which Nick Cave gives voice and song: the "universal condition" of yearning, and of loss; a "spirituality of rigor"; and the transcendent and moral dimensions of what music is about. This Australian musician, writer, and actor first made a name in the wild world of ’80s post-punk and later with Nick Cave and the Bad Seeds. He also underwent public struggles with addiction and rehab.

Since the accidental death of his 15-year-old son Arthur in 2015, and a few years later, the death of his eldest child Jethro, he has entered yet another transfigured era, co-created an exquisite book called Faith, Hope and Carnage, and become a frank and eloquent interlocutor on grief. As a human and a songwriter, Nick Cave is an embodiment of a life examined and evolved. He sat with Krista in the On Being studio in Minneapolis, and the gorgeous conversation that followed is woven in this episode with his gorgeous music.

Nick Cave — Loss, Yearning, Transcendence

A little musing on this season, the spectacular finale headed your way — and ways to stay connected in the time ahead.

A Word from Krista

Our built world is designed around something called "normal," and yet every single one of our bodies is mysterious, and constantly adapting for better or worse — and always, always changing. This is a fact so ordinary — and yet not something most of us routinely pause to know and to ponder and work with. But Sara Hendren has made it her passion, bringing to it her varied vocations and gifts: being a painter and loving how art reveals truth not by way of simplicity, but by juxtaposition; teaching design to engineering students; parenting three beloved children, one of whom has Down syndrome. 

This is a conversation that will have you moving through the world both marveling at the ordinary adaptations that bodies make and asking, in Sara's words, "restless and generative questions": of why we organize the physical world as though vulnerability and needs for assistance are not commonplace — indeed salutary — forms of experience that reveal the genius of what being human is all about.

Sara Hendren — Our Bodies, Aliveness, and the Built World

The ecological crisis we are standing before is at once civilizational and personal — intimately close to each of us in the places we love and inhabit, and unfolding at a species level. And as much as anyone alive on the planet now, Christiana Figueres has felt the overwhelm of this and stepped into service. She gives voice so eloquently to the grief that we feel and must allow to bind us to each other — and what she sees as a spiritual evolution the natural world is calling us to. 

If you have wondered how to keep hope alive amidst a thousand reasons to despair, if you are ready to take your despair as fuel — intrigued by the idea of stepping into love and immediate realities of abundance and regeneration — this conversation is for you.

Christiana Figueres — Ecological Hope, and Spiritual Evolution

This phrase recurs throughout Clint Smith's writing: "in the marrow of our bones." It is an example of how words can hold encrypted wisdom — in this case, the reality that memory and emotion lodge in us physically. Words and phrases have carried this truth forward in time long before we had the science to understand it.

Clint Smith is best known for his 2021 book, How the Word Is Passed, but he is first and foremost a poet. He and Krista discuss how his various life chapters have been real-world laboratories for him to investigate the entanglement between language and the intelligence of the body — and the related entanglement between history and place. His poetic sensibility has singularly opened readers to approach a generative reckoning with American history — on whatever side of that history our ancestors stood. 

Clint Smith has a way of making reckoning possible at a humanizing, softening, bodily level — in the marrow, you might say, of our bones.
