Salt Spray May Stifle Lightning over the Sea

by Carolyn Wilke 1 November 20224 November 2022

New research suggests that sea-salt aerosols seed large raindrops that starve clouds of water needed to make lightning. But not all scientists are convinced it’s simply about salt spray.

La visión de un artista que nos ofrece una visión de la formación de los planetas: Cerca de la estrella, las partículas de polvo se convierten en planetesimales y planetas similares a la Tierra. En la parte más lejana, el gas se acumula en los núcleos planetarios para la formación de gigantes similares a Júpiter.
