Get ready for a celestial spectacle! The Leonids meteor shower is upon us, and this year’s display promises to be even more captivating than usual.
For all you stargazers out there, the Leonids are a sight to behold. This annual meteor shower, which occurs every November, is about to reach its peak on November 16th and 17th. While meteor showers are a regular occurrence, the Leonids offer a unique and dramatic experience, providing a glimpse into the awe-inspiring world of meteor showers.
If you’re eager to witness this celestial event, Jonathan Blazek, an assistant professor of physics at Northeastern University, has some insights to share. Blazek explains that meteor showers are composed of debris left behind by orbiting comets. As these comets pass by the sun and heat up, they shed material that follows the same orbit, creating a trail of debris that eventually intersects with Earth.
“This debris, ranging from the size of a grain of sand to a small rock, burns up as it enters our atmosphere, leaving behind those brilliant streaks of light we call ‘shooting stars,'” Blazek elaborates. “And because of Earth’s regular orbit, we get to witness these meteor showers at the same time each year.”
The Leonids meteor shower, in particular, is made up of material shed by the comet 55P/Tempel-Tuttle, which completes its orbit around the sun every 33 years. The name ‘Leonids’ is derived from their constellation of origin, Leo, as Blazek points out.
Although the meteor rate during the Leonids can be as low as three per hour, according to NASA, these meteors are known for their brightness and sometimes even their colorful displays. Traveling at an impressive speed of about 44 miles per second, they are among the fastest meteors we encounter.
What makes the Leonids especially dramatic are the fireballs and Earth-grazer meteors, as NASA notes. Fireballs are larger, brighter explosions that linger in the night sky longer than the average meteor streak. Earth-grazers, true to their name, travel close to the horizon, leaving behind long, vibrant tails.
But here’s where it gets controversial… The Leonids meteor shower has another claim to fame. Every 30 years or so, it produces a ‘meteor storm,’ an event where Earth passes through a particularly dense clump of material from the comet. During these storms, the meteor rate can exceed 1,000 per hour! The Leonids put on an extraordinary show in 1966, with thousands of meteors falling in just 15 minutes. Since the last Leonid meteor storm occurred in 2002, this year’s event will be a more typical meteor shower, as Blazek explains.
So, where and how can you spot the Leonids? Blazek recommends following the usual guidelines for meteor-watching: find a dark spot away from city lights. “The most meteor activity will occur between midnight and sunrise when we’re facing the same direction as the motion of the Earth on its orbit,” Blazek advises.
And this year, stargazers have an extra advantage. According to the American Meteor Society, a waning crescent moon will rise late, leaving those prime Leonid viewing hours darker for a little longer.
