Roman on the Pad, JWST Galaxy Crisis & Dark Energy Wobble
Audio is available on Spreaker — see link below.
NASA's Nancy Grace Roman Space Telescope is six days from launch — and the universe it's flying into is already full of surprises. From a deepening JWST galaxy crisis to wobbling dark energy and a new dark matter technique, today's briefing covers the biggest stories in space and astronomy.

Six days from now, NASA's most anticipated observatory in a generation lifts off. The Nancy Grace Roman Space Telescope is encapsulated, cleared, and sitting on Falcon Heavy at Kennedy Space Center with an August thirtieth launch window.
Start with exoplanets. Roman is expected to detect around two hundred thousand new planets.
While Roman is still on the launchpad, JWST is already rewriting the rulebook. New spectral analysis of early massive galaxies reveals they contain three to four times more mass than previous estimates.
The dark energy picture is equally unsettled. Data from the DESI survey hints that dark energy may be weakening over cosmic time, which contradicts the standard cosmological model.
Two other signals worth tracking. China has delayed its Chang'e seven lunar south pole mission from August twenty twenty-six to early twenty twenty-seven.
The signal to watch over the next week is straightforward: does Roman launch clean on August thirtieth. Florida weather remains a variable, and no backup date has been announced.
