SpaceX launch paints glowing jellyfish cloud across East Coast sky
Web StoryWatch this story in 15 seconds →Key takeaways
- A SpaceX Falcon 9 rocket launched before dawn on Oct. 13, 2026. Its exhaust caught the sunlight and formed a glowing cloud shaped like a jellyfish.
- The cloud was not a UFO, a meteor, or a threat. It was a normal effect of a rocket launch near sunrise.
- The rocket carried cargo to the space station. It is set to dock on Thursday, Oct. 15.
People along the East Coast woke to a strange sight on Tuesday, Oct. 13. A glowing cloud shaped like a jellyfish spread across the dark morning sky.
It was a SpaceX rocket, not a UFO.
The cloud looked odd because it glowed in the dark. It spread wide and moved to the northeast. Many people took photos and asked what it was.
The answer is simple. A rocket launch near sunrise can paint the sky like this.
What happened
A SpaceX Falcon 9 rocket lifted off at 6:33 in the morning Eastern time on Tuesday, October 13. It left Space Launch Complex 40 in Florida.
The site sits at Cape Canaveral Space Force Station. The rocket flew on a path to the northeast.
The mission is called CRS-35. It is the 35th SpaceX resupply flight for NASA. A Dragon cargo craft rode on top of the rocket.
It carried more than 6,300 pounds of supplies. That number comes from NASA.
The cargo holds science and gear for the space station. It holds the last pair of new roll-out solar arrays. These arrays will help power the station.
The craft also holds work to make artificial retinas. It holds models of heart tissue made in 3D. It holds brain organoids for disease research.
NASA lists all of these in its mission plan.
For the full cargo list, see our report on the CRS-35 cargo flight. That story covers what the Dragon craft carries. This story covers the cloud in the sky.
The launch gave Florida a loud show too. The Falcon 9 booster came back to land. It touched down at Landing Zone 40 about seven minutes after liftoff.
People in Brevard County heard sharp sonic booms. A sonic boom is a loud crack from fast flight.
The sky show reached far past Florida. Dozens of viewers in North Carolina sent photos to WRAL. Early risers in central Pennsylvania saw it too.
A photographer in Hoboken, New Jersey, caught it near lower Manhattan. That report comes from Men's Journal.
The cloud moved to the northeast as it grew. It glowed against the dark sky. It faded as the morning light grew.
By full daylight, the show was over.
The rocket parts have flown before. The booster, called B1096, flew for the eighth time. The Dragon craft, called C211, flew for the fourth time.
SpaceX reuses its rockets and craft. That reuse keeps costs down.
Why it matters
The cloud was a trick of light. It was not a fire in the sky. It was not a sign of harm.
It was rocket exhaust lit by the sun.
Here is how it works, step by step. The launch took place before sunrise. The ground was still dark.
The sky above the ground was dark too. But the rocket climbed high and fast. At that height, it reached the sunlight.
The sun sat just below the horizon. It still lit the high sky.
The rocket leaves a trail of gas behind it. That trail is called exhaust. The sunlight hit the exhaust.
The exhaust glowed bright white and blue. The dark sky made the glow stand out. That is why the cloud looked so bright.
The cloud spread as it rose. Gas spreads out in thin air. High up, the air is very thin.
So the trail grew wide. The wide trail took the shape of a jellyfish. The bright head sat at the front.
The long trail hung behind it. Space fans call this a space jellyfish.
This happens with launches near sunrise or sunset. The timing must be just right. The ground must be dark.
The high sky must be in sunlight. When both are true, the exhaust glows. A launch at noon would not look like this.
The bright day sky would hide the glow.
Why did so many people see it this time? The path helped. The rocket flew to the northeast along the coast.
That path kept it in view for a long stretch. The sky was clear for many watchers. Many people were awake and outside.
They saw the glow and shared photos. Local news stations got a flood of pictures.
The sight also scared some people. A strange glow in the dark sky can feel scary. But the cause was plain.
It was a planned launch with a known path. NASA had set the launch time in advance. The agency shared the plan before liftoff.
The trend shows how fast news moves now. People saw the cloud and went online. They asked what it was.
Photos spread from state to state. Within hours, news outlets named the cause. The cloud was a rocket trail, lit by the sun.
For another recent sky show, see our report on the geomagnetic storm and aurora. That story covers a glow with a very different cause.
What happens next
The Dragon craft is now on its way to the space station. It is set to dock around 11 in the morning Eastern time on Thursday, October 15.
It will link with the Harmony module. That is the plan from NASA.
The trip takes about 52 hours. The craft flies on its own. It will stay at the station for about a month.
Then it will head home. NASA says it will splash down off the coast of California in mid-November.
The crew on the station will unload the cargo. They will set up the new solar arrays. They will start the science work.
The work covers eyes, hearts, and brains. It may help doctors on Earth one day.
Sky watchers can catch a show like this again. The key is the launch time. A launch near sunrise or sunset can glow.
A clear sky helps a lot. A path along the coast helps too. If you see a strange glow, check the launch news first.
The cause may be a rocket, not a mystery.
The next time a bright cloud fills the dawn sky, you will know the signs. A slow glow that moves in one path points to a launch. A fast streak that flares and dies points to a meteor.
A rocket trail grows wide and drifts. It fades as the sun rises. That is the jellyfish in the sky.
