In today's episode, JWST delivers a landmark result: the first longitude-by-longitude atmospheric map of an alien world. Ultra-hot exoplanet WASP-121 b has an asymmetric atmosphere, with its evening terminator running significantly hotter than its morning side. Powerful winds are redistributing heat faster than it can radiate away, and current climate models are underestimating the effect. Mineral cloud formation may be part of what's missing — and because WASP-121 b is a template for all tidally locked worlds, this methodology will shape how astronomers interpret atmospheres across the galaxy.
Interstellar comet 3I/ATLAS is confirmed to be 10 to 12 billion years old — a chemical relic from cosmic noon, the universe's peak era of star and planet formation. Its deuterium levels run 30 times higher than solar system comets, pointing to formation in a radically different environment. Only the third confirmed interstellar visitor ever detected, it's carrying a chemical record we could never otherwise sample.
ESA's Euclid telescope has produced the largest single image ever taken of the Milky Way's central bulge — 60 million stars in a 26-hour exposure. The image opens a new pipeline for exoplanet discovery via microlensing events in one of the galaxy's most densely packed regions.
SpaceX quietly launched a spacecraft called Starfall on a Falcon 9, described as a microgravity research platform with rapid cargo delivery capabilities flagged in FAA filings. Full purpose remains unclear.
Finally, a physicist has proposed using high-powered lasers to probe whether gravity has a quantum nature — a serious theoretical step toward one of physics' deepest open questions.
