Interstellar visitor #3 is here. We unpack 3I ATLAS (why it’s moving so fast, why we finally saw a tail, and how Hubble/JWST—and maybe even Juno—could nail down its makeup). Then we dive into the Vera Rubin Observatory, the 32-gigapixel camera that will turn the entire sky into a time-lapse movie and supercharge discovery. Next: AI just boosted CRISPR by predicting and guiding DNA repair (Pythia), making edits cleaner—especially in non-dividing neurons. And we close with a crossover of dinos + particle physics: preserved T. rex blood vessels revealed by a synchrotron. Mystery Box: the viral “Black aliens” meme.

We go from the universe’s first chemistry to tomorrow’s designer biology, swing by Mars to tune Europa Clipper’s ice radar, and finish with a fresh take on the double-slit experiment.

In this episode

• The “oldest molecule” puzzle (HeH⁺), cooling the early universe, and why JWST’s findings matter

• Programmable proteins: reassigning codons, recoding organisms, and real biosafety

• Europa Clipper’s REASON radar test at Mars: frequencies, ice thickness & ocean clues

• Double-slit, demystified: single photons, “which-path” info, and measurement reality
