  • 9854 - This Week in Space 230: Living on Lava Worlds

    Think you're having a hot summer? Try living on 55 Cancri-e, a super-Earth with daytime temperatures above 4000 degrees Fahrenheit. Most of these super-Earths orbit frighteningly close to their host stars and have long since had their atmospheres scraped away, leaving them baked, parched rocks. But some, like 55 Cancri, still have dense envelopes of air. How is that possible, when the planet is 20 times closer to its star than our own planet Mercury? Dr. Laura Schaefer explains how molten lava worlds defy the odds. Plus: Starship update, the first orbital data centers, and a new year on Mars.

  • 9852 - Hands-On AI 1: The Chatbot in Your Laptop

    Your next chatbot doesn't need the cloud. Mikah Sargent installs a free app, downloads an AI model, turns off the Wi-Fi, and keeps right on chatting, all on an ordinary computer. Along the way, he explains how to read a model listing, including what the size and "Q4" labels mean, so you can pick a model that runs well on your own machine. Then the local model goes head-to-head with a cloud assistant to see where it holds up and where it falls short.

  • 9851 - Hands-On AI: Welcome to Hands-On AI

    Hands-On AI is the show that turns AI confusion into AI confidence. In this introductory episode, Mikah Sargent lays out what the show is and isn't: short, focused episodes — most 10 to 15 minutes — that take one question, one tool, or one technique at a time. Some weeks go under the hood on what a large language model is actually doing. Some weeks get practical: the AI already in your pocket, or a model running entirely on your own computer. And some weeks are honest verdicts on the tools everyone's talking about.

    This show is a conversation. Send your AI questions to handsonai@twit.tv or reach out on TWiT's social media, and you might hear your question answered on the show.
