On 15th March, a coronal mass ejection from the Sun launched a torrent of charged particles in the direction of Earth. The gaseous cloud collided with our planet’s magnetic field two days later, generating this glorious, shimmering auroral curtain over Iceland photographed by Carlos Gauna.

Mysterious Martian dust cloud and aurora detected by NASA spacecraft

19 March 2015 Astronomy Now

Unlike the Earth, Mars lost a global protective magnetic field billions of years ago, so solar particles can directly strike the atmosphere. NASA’s MAVEN spacecraft recently detected extensive auroral activity in the Red Planet’s northern hemisphere, plus an unexplained high-altitude dust cloud.
