Now that we’re nearly into the second week of our “Currents” issue, I thought it’d be fitting to recall our interview with Lisa Kaltenegger, an astronomer at Cornell University and the director of its Carl Sagan Institute. Before Christopher Nolan’s Interstellar came out, in 2014, Kaltenegger sat down with Nautilus to discuss her work, and she rhapsodized about the physics and […]

On The Tonight Show, in March 1978, the late astronomer Carl Sagan had lots to talk about. He had just published Dragons of Eden: Speculations on the Evolution of Human Intelligence—which would win the Pulitzer Prize—and Star Wars, released the year before, still captivated the public’s imagination. When Johnny Carson, the show’s then-host, asked Sagan […]

Hope Jahren, a geobiologist and geochemist, wants to speak to you. For decades, she says, she’s been speaking to the same people, her scientific peers, and now it’s time for a change. “I wanted to write this book”—her memoir, Lab Girl, published today—“in order to talk to somebody new,” she told Nautilus recently. Her subject? […]

When Carl Sagan, the late astronomer and original Cosmos host, published his first novel, Contact, in 1985, Studs Terkel, the long-time radio broadcaster, asked him a month later to chat with him. Their subject, of course, was aliens, and the question of whether we’d ever establish good relations with them. Nautilus Members enjoy an ad-free experience. […]

The staunch atheist and essayist Christopher Hitchens once said that “the most overrated of the virtues is faith.” It’s a reasonable conclusion if you believe, as the astrophysicist Carl Sagan did, that “extraordinary claims require extraordinary evidence.”1 To believe something without evidence—or have faith—is, in their view, something to avoid (and, when called for, to […]

On June 18, 2014, a photo of a very handsome, no-name man was posted on the Web. Within 48 hours, it garnered 62,000 “Likes” on Facebook and became a media spectacle. Today, the Like count is up to almost 102,000, and the photo is still attracting comments. But thousands of pictures of highly attractive people […]

On February 3, Cliff Burgess, a physicist at McMaster University, emailed some of his colleagues about an exciting rumor—a possible discovery—that, if verified at a press conference later today, would mean a “Nobel prize is coming someone’s way.” Nautilus Members enjoy an ad-free experience.

We sit down with the virtual reality expert.

The usual space vista is of distant tumbling galaxies, or towering clouds of dust. The Hubble Ultra Deep Field, for instance, is a photograph of a patch of blackness representing just one 24-millionth of the whole sky. Over 11 days, the telescope soaked in whatever light came in, and the result was astonishing: Every point […]

We didn’t say “break the Internet” back in 1999, but if we did we could certainly say that science-fiction author David Brin broke the Internet when he wrote in Salon that “Stars Wars belongs to our dark past. A long, tyrannical epoch of fear, illogic, despotism and demagoguery that our ancestors struggled desperately to overcome, […]
