JWST Cycle 5: The Next Shot at K2-18b's Alleged Biosignature
JWST Cycle 5 begins observations around July 2026, and among its targets: K2-18b, the sub-Neptune 124 light-years away where a 2023 Cambridge-led team claimed to detect dimethyl sulfide — a molecule produced by marine life on Earth. A 2025 NASA-led reanalysis (Welbanks et al., arXiv:2508.05961) found the evidence does not meet the scientific standard of detection. Cycle 5 data could settle it — or complicate it further. This is the scientific method running in public, in real time.

Project Blue Book closed in 1969 with 701 officially unexplained cases. The Air Force has not reopened any of them. PURSUE's first 162 files didn't either. Release 02 landed May 22 — and it didn't close the record so much as lengthen it: green fireballs over New Mexico, 1949; glowing orbs splitting apart over a military range, late 2025. Seventy-six years, the same report filed twice. Nobody has explained either one.

Hurricane Season Opens: What NOAA's 2026 Outlook Says — and How the Markets Are Scoring It
Atlantic hurricane season officially starts June 1. NOAA's freshly released 2026 outlook forecasts above-normal activity, aided by La Niña or neutral ENSO conditions that suppress wind shear and warm the Atlantic. Prediction market KXHURCTOT-26DEC01 on Kalshi — $220K in volume, yes_price ~0.48 for 5+ named storms — turns NOAA's seasonal science into a live, publicly scoreable forecast.
