How many exoplanets are hiding in dust?

What can exozodiacal dust, also called exozodi, teach astronomers about identifying Earth-like exoplanets? This is what a recently submitted NASA white paper—which highlights key findings from the annual Architecture Concept Review—hopes to address as a team of researchers discussed how exozodi orbiting within a star’s habitable zone (HZ) could interfere with detecting Earth-like exoplanets.

Webb’s autopsy of planet swallowed by star yields surprise

Observations from NASA’s James Webb Space Telescope have provided a surprising twist in the narrative surrounding what is believed to be the first star observed in the act of swallowing a planet. The new findings, published in The Astrophysical Journal, suggest that the star actually did not swell to envelop a planet as previously hypothesized. Instead, Webb’s observations show the planet’s orbit shrank over time, slowly bringing the planet closer to its demise until it was engulfed in full.

True commercial alternatives for strategic communications and PNT don’t exist — yet

COLORADO SPRINGS – Military space leaders continue looking for ways to inject commercial technologies into their architectures. For strategic communications and positioning, navigation and timing, though, true commercial alternatives may […] The post True commercial alternatives for strategic communications and PNT don’t exist — yet appeared first on SpaceNews.

Rise of the ‘twin’

For years, researchers have built AI-powered models to simulate virtual scenarios of the planet. The concept, known as Earth’s “digital twin,” leverages a wealth of real-time data gleaned from satellites, […] The post Rise of the ‘twin’ appeared first on SpaceNews.

NASA’s Juno back to normal operations after entering safe mode

Data received from NASA’s Juno mission indicates the solar-powered spacecraft went into safe mode twice on April 4 while the spacecraft was flying by Jupiter. Safe mode is a precautionary status that a spacecraft enters when it detects an anomaly. Nonessential functions are suspended, and the spacecraft focuses on essential tasks like communication and power management. Upon entering safe mode, Juno’s science instruments were powered down, as designed, for the remainder of the flyby.
