Relâmpagos em Júpiter podem ser 100 vezes mais fortes do que na Terra

Pesquisadores que analisam dados da sonda Juno, da NASA, determinaram que os relâmpagos em Júpiter podem atingir intensidades até 100 vezes maiores do que as descargas típicas na Terra. As descobertas, baseadas em observações de micro-ondas de 2021 e 2022, destacam diferenças importantes na forma como as tempestades se formam no gigante gasoso.

O estudo, publicado na AGU Advances, utilizou o radiômetro de micro-ondas da Juno para medir as emissões de rádio dos relâmpagos durante períodos de redução da atividade de tempestades no Cinturão Equatorial Norte de Júpiter. Os cientistas registraram uma média de três relâmpagos por segundo em várias passagens, sendo que um encontro detectou 206 pulsos. Do total de 613 sinais, os níveis de energia variaram desde equivalentes aos relâmpagos terrestres até mais de 100 vezes mais fortes, embora comparações exatas permaneçam incertas devido aos diferentes comprimentos de onda observados.

NASA's Juno spacecraft has revealed that lightning in Jupiter's storms is at least 100 times more powerful than on Earth, based on data from 2021 and 2022. The findings, published on March 20 in AGU Advances, come as the mission's future hangs in balance due to budget constraints. NASA officials are weighing whether to extend operations amid funding shortfalls.

Researchers at Kyoto University have suggested a possible connection between solar flares and earthquakes through ionospheric disturbances. Their theoretical model indicates that electrostatic forces from space weather could influence stressed fault zones in Earth's crust. The study does not claim direct causation but highlights a potential interaction mechanism.

Scientists have found that localized dust storms on Mars can drive water vapor into the upper atmosphere, where it breaks apart and escapes into space. The discovery, based on observations from multiple Mars orbiters, challenges prior assumptions about when and how the planet loses water. Researchers link the effect to an intense regional storm during the Northern Hemisphere summer.

Astronomers have observed a supermassive black hole in galaxy J1007+3540 restarting powerful jets after nearly 100 million years of inactivity. The jets, distorted by intense pressure from a surrounding galaxy cluster, stretch nearly a million light-years. The findings reveal cycles of black hole activity shaping the galaxy's structure.
