Our second image in this Sunday Astronomy Picture of the Day (APOD) two-fer was originally captured in October 2012 in Yellowstone National Park in the United States: "Aurora Over White Dome Geyser." Diatomic nitrogen (N2, red) and monoatomic oxygen (O, lime-green) are at play here. Definitely worth a repeat performance.

This is a mesmerizing aurora image, Maj William W. 'Bill' Price! I have never seen one personally, but I expect that seeing one with one's own eyes would be awesome... Outstanding share, Bill!!!

Thank you my space-exploration advocate friend Maj William W. 'Bill' Price for posting the February 20th Astronomy Picture of the Day (APOD): ‘Aurora Over White Dome Geyser’
Image: Aurora Over White Dome Geyser
Explanation: Sometimes both heaven and Earth erupt. Colorful auroras erupted unexpectedly a few years ago, with green aurora appearing near the horizon and brilliant bands of red aurora blooming high overhead. A bright Moon lit the foreground of this picturesque scene, while familiar stars could be seen far in the distance. With planning, the careful astrophotographer shot this image mosaic in the field of White Dome Geyser in Yellowstone National Park in the western USA. Sure enough, just after midnight, White Dome erupted -- spraying a stream of water and vapor many meters into the air. Geyser water is heated to steam by scalding magma several kilometers below, and rises through rock cracks to the surface. About half of all known geysers occur in Yellowstone National Park. Although the geomagnetic storm that caused the auroras subsided within a day, eruptions of White Dome Geyser continue about every 30 minutes.
