Over the next several weeks, our planet will have a close encounter with the Taurid meteor swarm. It will be the closest that we have been to the center of the meteor swarm since 1975, and we won’t have an encounter this close again until 2032. So for astronomers, this is a really big deal. And hopefully there will be no danger to Earth during this pass, but some scientists are absolutely convinced that the Tunguska explosion of 1908 which flattened 80 million trees in Russia was caused by an object from the Taurid meteor swarm. As you will see...

Every year, Earth passes through the tail of the comet Encke - twice. This isn’t unusual. We regularly cross cometary trails of ice and dust. But this one may be different. It could have been the source of the dramatic 1908 Tunguska airburst which flattened hundreds of square kilometres of Russian forest. The 45m wide comet fragment struck on June 30, at the height of the Beta Taurid shower. Was it, in fact, a part of that shower? Astronomer and science advocate Dr Phil Plait says it is possible. Calculations of its trajectory indicate the Tunguska object came from the...

The Taurid meteors, sometimes called the "Halloween fireballs," show up between mid-October and mid-November, but Nov. 5 to 12 will likely be the best time to look for them this year, taking into account both their peak of activity and the effect of increasingly bright moonlight on viewing conditions. After the Moon sets – around 11 p.m. local time on Nov. 5, later on subsequent nights – some 10 to 15 meteors may appear per hour. They are often yellowish-orange and, as meteors go, appear to move rather slowly. Their name comes from the way they seem to radiate from...
