What has more power: Earth’s aurorae or fireworks shows?
Source ↗ 👁 0 💬 0
Here on Earth, brilliant spectacles occasionally illuminate our night skies.



The peak of January 19, 2026’s auroral display was brief, and visible in spectacular fashion only for the short period of time where the Earth’s and Sun’s relevant magnetic fields were anti-aligned during the intense solar radiation storm that sent charged particles rapidly from the Sun to Earth. The resulting photograph, from northern Scotland, is one of the best views of this brief light show.
