There's a gigantic solar flare on Tuesday, and those charged particles will collide with earth's atmosphere to produce the ethereal-looking northern lights.

Which makes this then, the perfect time to catch them. They are only visible at or near the pole, because solar particles are channeled by the earth's magnetic field. When the massive solar storm reaches the eath tonight, northern lights can be seen pretty clearly.



The earth's magnetic field is shaped so that charged solar particles are channeled toward the poles, where they create auroras. . NASA
