A starry Night of Iceland

This breathtaking imsge was captured in Iceland, and to no suprise won a photography award for being so beautiful. This is a picture of the largest glacial lake in Iceland, known as the Jokulsarlon.The bright green lights above and reflection off of this lake are called auroral rings. These auroral rings are the result of the collision of charged particles in Earth's atmosphere.This phenomena takes places in the ionosphere, usually at night or around dusk. These lights are directed by Earth's magnetic field and typically occur within polar regions. Amazingly, these auroras can also be seen out in space, and have been found to also occur on planets! In the backround of these auroras, the andromeda galaxy can be seen along with the Milky Way and the Pleiades. As we near the solar maximum, we will experience an increased number of these beautiful auroras.
