Title: NASA’s Astronomy Picture of the Day captures amazing auroras sparked by geomagnetic storm

NASA’s Astronomy Picture of the Day for March 27, 2023, showcases stunning auroras sparked by a geomagnetic storm. The image was captured on March 25, 2023, near Chatanika, Alaska. The auroras were created by a coronal mass ejection from the Sun, which produced a geomagnetic storm when it interacted with Earth’s magnetic field. The storm produced a dazzling display of green and purple auroras that illuminated the night sky. The image was captured using a time-lapse technique that recorded 172 individual exposures over a period of three hours. The final image is a composite of these exposures. The Astronomy Picture of the Day is a daily feature produced by NASA that showcases some of the most spectacular images of the universe captured by astronomers around the world.
