October is a special month for astronomy lovers, because around this time every year, Earth passed through the tail of debris left behind by three different comets.
As we reported earlier this month, the shower will hit its peak on the night of October 20 and early morning of October 21, when you’ll get a chance to see up to 20 meteors per hour burning up in Earth's atmosphere all night long.
These meteors are known as Orionids, because they appear to emanate from a region to the north of the second-brightest star in the Orion constellation - Betelgeuse.
They were originally meteoroids, formed from the remnants of the nucleus - or rocky core - of Halley's comet. Since breaking apart from the comet, they’ve remained as a swirling cloud of rubble, shadowing it as it orbits the Sun every 76 years.
As Earth passes through this dirt cloud twice a year, these meteoroids burn up in our atmosphere to become meteors - otherwise known as shooting stars.
The Orionids meteor shower can also produce fireballs, which are meteors that shine extremely bright for a few seconds before fading.
For the best chance of spotting the meteors, you’ve got to think strategically - meaning don’t just step onto your balcony and wonder where all the shooting stars are, find somewhere with low light pollution, lie back on a deck chair, and wait.
Your best bet to spot these beauties is to get out of town where the nights are darker, and give your eyes time to adjust.Check out this light pollution mapto help you find a spot.
You’ll also need to find the Orion constellation in the sky so you know where the meteors are going to appear (called the radiant), and the easiest way to do that is to look for Orion’s belt - three stars that are pretty much evenly spaced in a straight line...
