Each autumn, the Earth drifts through the dusty wake left behind by Comet Encke, and this week that old crossing grows unusually dramatic. On Tuesday and Wednesday nights, the Southern Taurid shower is expected to peak, offering the chance of fireballs bright enough to briefly turn night into day. The rarity lies in 2025 being a swarm year, when the planet passes through a denser stretch of the comet's debris, reminding us that even ordinary celestial rhythms can hold surprises for those who look up.
Southern Taurid Meteor Shower Peaks This Week With Bright Fireballs, Though Moonlight May Dim the Show
Baseballs up to basketballs, but they appear as fireballs from the ground
Mark
Why is this year different from a normal Taurid peak?
Mimi
It's a swarm year. Earth is crossing a part of Comet Encke's tail that holds a lot of fragments, so up to 10 bright meteors an hour are possible.
Mark
And the fragments are bigger than usual?
Mimi
Much bigger. Lunsford says normal Taurid particles are about pea gravel size, while swarm particles run from baseballs to basketballs. That's why they look like fireballs.
Luke
Worth noting that "up to 10 an hour" is a maximum. It's not a count anyone is guaranteeing.
Mark
What about the other showers overlapping?
Mimi
The Northern Taurids and Orionids are active at the same time, which the American Meteor Society says raises the odds of fireballs.
Luke
Raises the odds, yes, but the source gives no number for how much.
Mark
So what could spoil it?
Mimi
A nearly full moon, and clouds. Midnight is the best window, according to EarthSky.
Luke
And how much the moon will actually dim things isn't quantified. That's still an open question until people look up.
Der Puls
- Fireballs from the Southern Taurids could briefly flood the night sky with light this Tuesday and Wednesday.
- A nearly full moon threatens to wash out the faint streaks, and clouds could hide what remains.
- Skywatchers are being urged to look up around midnight, when the display is expected to be strongest.
- Up to 10 bright meteors an hour are possible, though the final count depends on the moon and the weather.
Each autumn, the Earth drifts through the dusty wake left behind by Comet Encke, and this week that old crossing grows unusually dramatic. On Tuesday and Wednesday nights, the Southern Taurid shower is expected to peak, offering the chance of fireballs bright enough to briefly turn night into day. The rarity lies in 2025 being a swarm year, when the planet passes through a denser stretch of the comet's debris, reminding us that even ordinary celestial rhythms can hold surprises for those who look up.
On Tuesday and Wednesday nights, the Southern Taurid meteor shower is expected to reach its peak, and anyone who steps outside around midnight may catch fireballs bright enough to light up the sky. The forecast, reported by UPI on Nov. 4 with input from the American Meteor Society, Space.com and EarthSky, carries an unusual promise.
The shower is born from Comet Encke, which sheds a trail of dust as it travels. When Earth crosses that trail, particles hit the atmosphere at high speed and burn up. This year, the overlap with the Northern Taurids and Orionids adds more debris to the sky at once, and 2025 is a swarm year, when Earth passes through a part of the comet's tail thick with larger fragments.
Robert Lunsford of the American Meteor Society explained that ordinary Taurid particles are about the size of pea gravel, while swarm particles range from baseballs to basketballs. That size difference is what turns streaks into fireballs.
The sky, however, has its own plans. The nearly full moon may wash out some of the display, and clouds could block the view. The forecast is a ceiling, not a guarantee: up to 10 bright meteors an hour, with moonlight and weather deciding how many are actually seen.

The shower comes from Comet Encke. As the comet moves through space, it leaves a trail of dust and debris, and when Earth crosses that trail, the particles strike the atmosphere at high speed and burn up. According to the American Meteor Society, the shower is active between September and November.
This week's peak overlaps with two other showers, the Northern Taurids and the Orionids. The society says that overlap raises the chance of seeing fireballs, because more cosmic debris is burning up in the atmosphere at the same time.
Fireballs from the Southern Taurids are known for their brightness. Space.com says they can momentarily turn night to day as they flare across the sky.
The year itself adds to the forecast. 2025 is what astronomers call a swarm year, when Earth passes through a part of Encke's tail that holds an unusually large number of fragments. In a swarm year, up to 10 bright meteors may be visible each hour.
Robert Lunsford, an expert with the American Meteor Society, explained the difference in an email to Space.com. Ordinary Taurid particles are usually about the size of pea gravel, with a few larger pieces mixed in. The swarm particles are far bigger, ranging from the size of baseballs up to basketballs, and from the ground they appear as fireballs rather than ordinary meteors.
Timing matters for anyone planning to watch. EarthSky says the best viewing is around midnight. The main obstacle is the moon, which is nearly full and may wash out some of the display with its light. Clouds could also get in the way.
The forecast is a ceiling rather than a promise: up to 10 bright meteors an hour, with moonlight and weather deciding how many of them are actually seen.
