Astronomy - NIGHT ON A SPOOKY PLANET


Explanation: What spooky planet is this? Planet Earth on a dark and stormy night, of course. The ghostly scene was photographed at Hverir, a geothermally active area found along northeastern Iceland's volcanic landscape. Triggered by solar activity, geomagnetic storms have unleashed energetic particles trapped in Earth's magnetic field. Penetrating the planet's upper atmosphere at high latitudes, the particles create auroral displays in the starry night sky. Ghostly towers of steam and gas are venting from local fumaroles to dance against the eerie, greenish northern lights. For now, auroral activity on planet Earth remains in a high state as the Sun is only in early phases of decline from the peak of its solar activity cycle. And soon, other ghostly apparitions may dance in your neighborhood. Happy Halloween!

Explanation: What spooky planet is this? Planet Earth of course, on a dark and stormy night in 2013 at Hverir, a geothermally active area along the volcanic landscape in northeastern Iceland. Triggered by solar activity, geomagnetic storms produced the auroral display in the starry night sky. The ghostly towers of steam and gas are venting from fumaroles and danced against the eerie greenish light. For now, auroral apparitions are increasing as our Sun approaches a maximum in its 11 year solar activity cycle. And pretty soon, ghostly shapes may dance in your neighborhood too.
