Space News: NASA rocket takes first multi-point look inside radio-disrupting clouds
1+ week, 1+ day ago (474+ words) High above Earth, thin veils of metallic haze drift through the edge of space. Known as sporadic E layers, these high-altitude “clouds” form from the vaporized dust of burnt-up meteors, earning their name from the unpredictable way they emerge and…...
Astronomers Spotted a 'Bear' on Mars
4+ hour, 44+ min ago (186+ words) On 12 December 2022, an orbiter traveling 251 kilometers (156 miles) above the southern highlands of Mars photographed a hill....
A Breakthrough Listen survey was thought to have covered about 288,000 stars catalogued by Gaia. But a new simulation of the Milky Way estimates that more than 6.18 million stars actually fell within its radio-telescope beams—millions of potential worlds too faint or distant for Gaia to catalogue reliably, yet still within range if they were transmitting strongly enough.
10+ hour, 14+ min ago (1228+ words) A Besançon Galaxy Model reanalysis expands Breakthrough Listen's stellar bycatch to 6,182,364 simulated objects, while strong transmitter limits remain conditional on distance, power and duty cycle....
Bendy Missiles: New Study Reveals How Flexibility Shapes Supersonic Flight
7+ hour, 33+ min ago (604+ words) Modern supersonic missiles and launch vehicles are engineered to be extraordinarily slender, a design choice that slices through aerodynamic drag and lets the vehicle sprint through the atmosphere at remarkable speeds. Yet that elegance comes at a hidden price....
