You saw them. Or maybe your neighbor did, and now your group chat is a mess of blurry smartphone photos and "UFO" jokes. It’s a weird feeling, honestly. One minute you’re just taking the bins out, and the next, there’s a literal parade of glowing orbs trekking across the stars in a perfect, eerie line. It doesn't look like a plane. It definitely isn't a shooting star. If you spotted those weird lights in the sky last night, you aren't alone, and no, you haven't stumbled into the opening scene of an alien invasion movie.
Most of the time, the answer is frustratingly industrial.
The Starlink Effect and Why It Looks So Weird
SpaceX is basically a cosmic construction company at this point. When people report a "train" of lights moving in a straight line at a consistent speed, they’re almost always seeing a fresh batch of Starlink satellites. Elon Musk’s company launches these things dozens at a time. Right after deployment, they’re clustered together in low Earth orbit. Because they’re still gaining altitude, they reflect the sun—even if it’s dark where you’re standing—making them look like a luminous pearl necklace draped across the night sky.
They fade.
As the satellites reach their operational orbit, they spread out. They also tilt their solar panels, which makes them way less reflective. If you saw the lights in the sky last night and they seemed to "disappear" mid-flight, they probably just moved into the Earth’s shadow. It’s not a cloaking device. It’s just geometry.

Not Everything Is a Satellite
Sometimes the lights aren't moving in a line. Sometimes they’re flickering, or stationary, or dancing. This is where it gets interesting for amateur astronomers and "what was that" enthusiasts.
The Geminids or Perseids often get the credit, but meteor fireballs happen year-round. A fireball is basically a space rock that’s big enough to survive a few extra seconds of friction. They can glow green, blue, or bright white depending on their chemical makeup. Magnesium burns bright white. Nickel glows green. If the lights in the sky last night lasted only a few seconds and had a tail, you caught a fragment of our solar system’s leftover trash burning up at 25,000 miles per hour. Cool, right?
Space Weather: The Northern Lights Are Moving South
We are currently in a period of high solar activity. The sun goes through an 11-year cycle, and we’re nearing the "Solar Maximum." This means more solar flares and more Coronal Mass Ejections (CMEs).
When a CME hits Earth’s magnetic field, it creates a geomagnetic storm. In 2024 and 2025, we’ve seen the Aurora Borealis—the Northern Lights—reaching as far south as Arizona and Florida. It doesn't always look like the vibrant green curtains you see in National Geographic. To the naked eye, a weak aurora often looks like a faint, reddish glow or a "smudge" of white light. People often mistake this for light pollution until they look through their phone camera, which picks up the colors much better than the human eye.

If you noticed a shimmering pink or purple hue among the lights in the sky last night, you were likely witnessing a high-latitude aurora. This isn't just "pretty." It's a sign of a massive energy exchange between the sun and our atmosphere.
The Role of Rocket Launches
If you live anywhere near the coast—specifically Florida, California, or even Wallops Island in Virginia—your "UFO" might just be a "Space Jellyfish."
This happens when a rocket launches shortly after sunset or before sunrise. The rocket is high enough to be hit by sunlight, but the ground is in darkness. As the rocket’s exhaust plume expands in the thin upper atmosphere, the sun illuminates it, creating a glowing, ethereal cloud that looks like it belongs in a sci-fi flick. It’s a spectacular sight, but it’s just frozen water vapor and exhaust gases catching the light.
Identifying What You Saw
It's actually pretty easy to debunk most sightings if you have the right tools. You don't need a PhD. You just need a couple of apps and a bit of timing.

- Check the Flight Path: Apps like Flightradar24 show every commercial and private plane in real-time. If the light had blinking red and green strobes, it was a plane. Period.
- The Satellite Tracker: Use an app like "Heavens-Above" or "Night Sky." These use your GPS to show exactly what satellites were overhead at a specific time. You can literally scroll back to the time you saw the lights in the sky last night and see if a Starlink pass or the International Space Station (ISS) was scheduled.
- The ISS Factor: Speaking of the ISS, it’s the third brightest object in the sky. It looks like a very bright, steady white light moving across the sky over about 2 to 6 minutes. It doesn't twinkle. It doesn't change direction.
Why Do We Get So Excited?
Psychologically, we’re wired to look for patterns. It's called pareidolia. When we see something in the sky that doesn't fit our mental model of a "plane" or a "star," our brains fill in the gaps with the most exciting possibility. It’s why people still swear by Roswell or think every drone is a visitor from the Pleiades.
Actually, drones are a huge factor now. Professional drones used for light shows or mapping can hover, zip at 50 mph, and change color instantly. If the lights in the sky last night were hovering or moving erratically over a local park, you were probably watching a hobbyist or a commercial pilot.
What to Do Next Time
If it happens again—and it will—don't just grab a blurry photo. Try to find a reference point. Is the light moving past a specific tree? Is it higher or lower than the moon?
Most importantly, look at the "flicker." Stars twinkle because of atmospheric turbulence. Satellites and planets generally don't. If the light is steady and moving, it’s man-made. If it’s steady and staying still, it’s likely Jupiter or Venus, which can be shockingly bright depending on the time of year.
Practical Steps for the Next Sighting
- Download a Star Map: Get an app like SkyView or Stellarium. Point your phone at the spot where you saw the lights. It will tell you if there’s a planet or a known star cluster there.
- Check Space Weather: Websites like SpaceWeather.com track solar flares. If there was a big flare two days ago, those weird lights were almost certainly an aurora.
- Report It: If you’re truly stumped, the American Meteor Society or the National UFO Reporting Center (NUFORC) takes reports. They cross-reference sightings to see if multiple people saw the same thing from different angles, which helps calculate the object's altitude and speed.
Seeing strange lights in the sky last night is a reminder that the space above our heads is getting crowded. Between thousands of new satellites, increased solar activity, and more people flying drones, the "quiet" night sky is a thing of the past. It's a bit more chaotic up there now, but usually, there’s a very earthly explanation for those celestial mysteries.
Check your local satellite transit schedules for the next 48 hours. Chances are, that "train" of lights is coming back for an encore performance as the next cluster of satellites finds its home in the dark.
