Glossy ‘storm of the day’ auroras that glow in Jupiter’s morning sky are born in darkness

Jupiter’s other worldly gloss of polar auroras is occasionally illuminated by short but intense early morning displays known as morning storms. Now, for the first time, scientists have discovered where morning storms come from, how they grow, and that they are even more powerful than expected.

Scientists knew about morning storms from telescopes in space and beyond Land. But most of these instruments gave only a few glimpses of the storms, showing what was to be seen on the sun-facing side of Jupiter.
