Dopo la presentazione delle nuove 5 stelle, #ControlloDellIA, #EguaglianzaDistributiva , #LavoroNext-Gen , #FuturoFormativo e #SaluteMentale , presentiamo #StaRevolution , uno spazio politico digitale creato per abbattere, attraverso la forza che attribuiamo al digitale, le barriere e dare voce a chi non ce l’ha e creare quindi nuovi spazi di partecipazione democratica.
Obiettivo fondante dell'associazione è aumentare la partecipazione dei giovani alla vita pubblica.
Ed è questo che faremo.

Striking! Direct radio imaging of a star not in our direct vicinity showing how it evolves with time… the animation is not computer generated, is the result of this direct imaging!

Astronomers track bubbles on a star’s surface in the most detailed video yet | ALMA Observatory

For the first time, astronomers have captured images of a star other than the Sun in enough detail to track the motion of bubbling gas on its surface. The images of the star, R Doradus, were obtained with the Atacama Large Millimeter/submillimeter Array (ALMA), in July and August 2023. They show giant, hot bubbles of...
