Earth experiences high activity Taurid meteor showers
Recent reports of fireballs in the sky above Thailand and Poland could be a sign of Earth’s movement into the comet debris known as the Taurids meteor shower.

Earth is currently moving through the debris from Comet Encke, causing a meteor shower visible in the night sky as the cosmic dust hits the planet’s atmosphere at just under 105,000 kilometres per hour.
These pieces of dust are only the size of small pebbles, but the speeds at which they hit Earth’s atmosphere are sufficient to cause bright streaks in the sky.
But while most years see a relatively minor light display, 2015 is currently experiencing higher activity than usual.
“Individuals should not be surprised if they see a bright meteor or fireball over the next few nights.”
The rise in meteor activity is known as the Taurid ‘swarm’ and is caused as Earth moves into a swarm of fragments from the comet.
According to Asher, these Taurid swarms are known to cause fireballs visible in the sky.
