Petir di Jupiter bisa 100 kali lebih kuat daripada di Bumi

Para peneliti yang menganalisis data dari wahana antariksa Juno milik NASA telah menentukan bahwa petir di Jupiter dapat mencapai intensitas hingga 100 kali lebih besar dibandingkan sambaran petir pada umumnya di Bumi. Temuan ini, yang didasarkan pada pengamatan gelombang mikro dari tahun 2021 dan 2022, menyoroti perbedaan utama dalam cara badai terbentuk di planet raksasa gas tersebut.

Studi yang diterbitkan dalam AGU Advances ini menggunakan radiometer gelombang mikro milik Juno untuk mengukur emisi radio dari petir selama periode berkurangnya aktivitas badai di Sabuk Ekuator Utara Jupiter. Para ilmuwan mencatat rata-rata tiga kilatan per detik di berbagai lintasan, dengan satu pertemuan mendeteksi 206 pulsa. Dari total 613 sinyal, tingkat energi berkisar dari yang sebanding dengan petir di Bumi hingga lebih dari 100 kali lebih kuat, meskipun perbandingan pastinya masih belum pasti karena perbedaan panjang gelombang yang diamati.

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.
