Ten fascinating natural phenomena

Aurora Borealis: Undoubtedly one of the most beautiful natural phenomena, Auroras, also known as northern and southern lights, are natural light displays in the sky, usually observed at night, particularly in the Polar regions. The phenomenon occurs when the sun gives off high-energy charged particles that travel out into space.
Penitentes
Penitentes are huge ice spikes, so named due to their resemblance to hooded monks, and can be found on mountain glaciers. The spikes can reach up to 5m in height and are a caused by the sun's rays penetrating certain parts of the ice deeper than others, causing peaks in between the dimples.
Taos Hums Due to the fact they were first recorded in the New Mexico town of the same name, most strange rumbling noises heard without any identifiable source are referred to as Taos hums. The 'hums' are actually more commonly found in Europe and have been likened to the sound of a idling diesel engine. Listen to a clip of the sound here: http://ind.pn/aOxGTY.
