NASA’s Hubble Unexpectedly Catches Comet Breaking Up

In a happy twist of fate, NASA’s Hubble Space Telescope just witnessed a comet in the act of breaking apart. The chance of that happening while Hubble watched is extraordinarily minuscule. The findings published Wednesday in the journal Icarus. The comet K1, whose full name is C/2025 K1 (ATLAS)—not to be confused with interstellar comet […]

NASA’s X-59 Prepares for Second Flight

NASA’s X-59 experimental aircraft is preparing for its second flight, a step that will set the pace for more flight testing in 2026. Over the coming months, NASA will take the quiet supersonic jet faster and higher, while validating safety and performance, a process known as envelope expansion. NASA test pilot Jim “Clue” Less will be at the X-59’
