_Last night’s strong geomagnetic storm painted the sky with an unusually __rare red aurora – and from the International Space Station it looked like the crew was __literally flying through the glowing curtain.

Why the red? Green auroras typically glow around ~100 km altitude, but _red emissions come much higher (~300–400 km), where the atmosphere is thinner and it takes more energy to light it up – which is why this color is far less common.
