NASA's 'beauty & the beast' aurora image comes with a warning

NASA recently shared a spectacular picture of the Northern Lights adorning the sky in Iceland - but it came with a warning. Nasa said that the "beauty and the beast" aurora could wreak havoc on Earth. The image was captured by astronomer Juan Carlos Casado in 2016 in Iceland, and selected as NASA's Astronomy Picture of the Day on Sunday. While an aurora is perceived harmless, scientists warn that a particularly strong solar flare could one day release a pulse of charged particles capable of bringing down Earth's communication networks.
