Interstellar Comet 3I/ATLAS Survives Solar Flyby, Unveiling Secrets from Beyond Our Solar System

The third confirmed interstellar visitor ever detected, comet 3I/ATLAS, successfully completed its journey through our solar system in late 2025, providing scientists with unprecedented data about material from another stellar system. Discovered on July 1, 2025, by a NASA-funded survey telescope in Chile, the comet survived its closest approach to the Sun on October 30 and made its nearest pass to Earth on December 19, triggering an international observing campaign involving more than a dozen space missions and ground-based telescopes.

Thwaites Glacier: A Lost Drill, a Valuable Measurement, and Why ‘Under‑Ice’ Data Matters

A recent Thwaites Glacier drilling attempt lost instruments under the ice—but still produced rare measurements of the warming water beneath. For climate risk, these under‑ice observations are the difference between guesswork and credible sea‑level forecasts.

OpenClaw Isn’t ‘Just Another Bot’: Why Personal Agent Gateways Are the Next UI Layer

OpenClaw turns the messaging apps you already use into a control plane for AI agents—via a long-running gateway, pluggable channels, and a session model that feels more like an operating system than a chatbot. Here’s what the ‘personal agent gateway’ phenomenon is, why it’s emerging now, and where it can go next.
