Nice short discussion of the evolving understanding of 3I/ATLAS as this interstellar comet continues its approach to the Sun and more observations come in from various telescopes, featuring a lot of the observing folks 🔭☄️🧪
Telescopes Reveal Surprising Chemistry of a Rare Interstellar Object Passing Through Our Solar System
Called 3I/ATLAS, the object is only the third of its kind known to astronomers, and it’s likely been heading our way for billions of years, carrying pristine material from another star system

Looking forward to the launch of the Protoflight FireSat mission tonight on Transporter-13. FireSat is designed to detect and monitor wildfires to give first responders accurate, timely, and comprehensive information about fire conditions.
