Welcome to Analog Science Fiction and Fact! A lifelong appreciation of science fiction has led me to an incredibly fulfilling career with Analog…

Analog Science Fiction and Fact is the most enduring and popular science fiction magazine in history. Launched in 1930, Analog offers imaginative fiction reflecting the highest standards of scientific accuracy, as well as lively fact articles about current research on the frontiers of real science. A guiding principle for both fiction and provocative opinion columns is the exploration of the impact of science and technology on the human condition.

Meet the pantheon of Analog Science Fiction and Fact authors. In addition to a Who’s Who of outrageously famous writers, you’ll also find short bios of authors in the current issue, in-depth factual articles examining the processes particular authors utilize, and more. Visit often – there’s always something new to discover!

When a humble tinker’s apprentice in a failing colony has a chance at the adventure of a lifetime (or more), it may also mean leaving his home behind to face its fate; what choice can he make? Find out in our lead story, “The Tinker and the Timestream,” by Carolyn Ives Gilman.

Then we present a pair of fact articles for your enjoyment: a deep dive into planetary formation from Kevin Walsh, in “Why are the Keplerians so Different?” as well as a “Big Ideas” piece about extinc­tions and the Fermi Paradox from Howard Hendrix, “The Passenger Pigeon and the Great Filter.”

Practical resources for readers and writers, including the Analog Index, Writer’s Submission Guidelines, upcoming Science Fiction events, News, and more.

The beautiful, deadly sun had just gone down, and the twilit air was intoxicating with the breath of plants exhaling in relief when Rustem climbed the clock tower to make his nightly measurements. He had done so almost every night for the last twenty years—first toddling up the stone steps with his mother, and then, when she had grown too weak, on his own. Now, what had started as her pet project was his. READ MORE


Death Spiral
by Kate MacLeod

Sanyah Allani had fallen asleep with the hologram running again. The chair she slouched in might be the same as the one in her quarters, but it was never as cozy there surrounded by rough-hewn rock walls as it was in her virtual reality. The fire in particular was always such a vivid illusion she could almost feel its warmth and smell the seasoned wood slowly turning into ash.

The hologram dropped instantly when the call came through, thrusting her too quickly back into reality. The figure of her husband Desmon on the chair opposite hers looked up at her in surprise, then flickered out of existence, leaving her staring at the rock wall that was much closer to her than his chair had been.
