Blue meteor lights up night sky in Australia

Blue meteor lights up the night sky in Cairns, Australia.

According to Sputnik , security cameras at Cairns International Airport accidentally recorded a meteor with blue light falling on Cairns city in Queensland state on the evening of May 21.

Security camera footage shows the meteor burning with a green light in the Cairns night sky before plunging into a mountain range.

Several other Cairns residents also captured the meteor shower last weekend.

Soon after, other videos capturing the phenomenon began to flood social media.

According to local media, the Queensland state government still decided to organize a search for the meteor even though it was not certain whether it would fall to the ground or not.

The colour of a meteorite that burns up as it hits Earth's atmosphere is often determined by its composition. In the case of the Cairns meteorite, its green colour indicates it contains a high amount of magnesium ore, while iron-containing meteorites are yellow.

However, shooting stars and meteorites are only beautiful when they burn up in the sky because when they fall to Earth, they are dangerous objects. Even small rocks can produce huge kinetic energy. Typically, the Chelyabinsk meteorite was only 17 meters wide but could create an explosion with the destructive power of up to 500 kilotons of TNT.

Every year, about 17,000 meteorites do not burn up completely when flying through the Earth's atmosphere, although most of them are almost insignificant in size. However, there are occasional exceptions, with large meteorites falling in populated areas or near where people live.
