That Glowing "Space Jellyfish" in the Morning Sky Was a SpaceX Rocket — Here's Why It Looked That Way

What was the glowing jellyfish in the sky this morning?

It was a SpaceX rocket. Early on Tuesday, October 13, a Falcon 9 launched from Cape Canaveral in Florida and created a glowing, jellyfish-shaped plume that people photographed all along the East Coast. It was not a meteor, a comet, or a UFO — it was NASA's SpaceX CRS-35 cargo mission heading for the International Space Station, lit up by sunlight before sunrise reached the ground.

If you were up before dawn and saw a bright orb trailing a soft, expanding cloud, you were not alone. Photos and videos poured in within minutes, from Palm Beach County to Northeast Florida, from South Carolina's Upstate to North Carolina, central Pennsylvania, and even the New York City area. For a few strange, beautiful minutes, half the East Coast was looking up and asking the same question.

What happened: a 6:33 a.m. launch from Cape Canaveral

The Falcon 9 lifted off at 6:33 a.m. ET on Tuesday, October 13, from Launch Complex 40 at Cape Canaveral Space Force Station, according to Florida Today and the Palm Beach Post. The rocket carried a Cargo Dragon spacecraft on CRS-35, SpaceX's 35th resupply mission for NASA under its Commercial Resupply Services contract.

On board is more than 6,300 pounds of supplies, equipment, and science for the astronauts living on the space station. The Palm Beach Post noted the cargo also includes a student experiment from Florida Tech in Melbourne, Florida — a nice local detail inside a mission that suddenly became a regional sky show.

Minutes after liftoff, the Falcon 9's first-stage booster came back down to Landing Zone 40, roughly seven minutes into the flight, and people across Brevard County heard the familiar sonic booms that come with a returning booster, Florida Today reported.

Why did it look like a jellyfish?

The short answer: timing. The launch happened well before sunrise in Cape Canaveral, which was at 7:21 a.m. that morning. On the ground it was still dark, but high in the atmosphere the rocket was already high enough to catch sunlight.

When that sunlight hits the rocket's exhaust plume, the expanding vapor glows and spreads out instead of staying as a thin trail. From below, it can look like a luminous cloud with a bright head and a widening tail — which is exactly why space fans call the effect a “space jellyfish.” The same explanation was given by outlets in multiple states on Tuesday, including the Greenville News, which described early risers in the Upstate seeing a glowing orb followed by a streak of light, and The Spun, which traced sightings from Florida up toward New York.

That dawn-or-dusk window is the key ingredient. Launch too early or too late in full daylight, and the plume is far less dramatic. Launch in this narrow window, on a clear morning, on a northeast trajectory — as this one flew — and people hundreds of miles away can see it.

Why it's blowing up online

First, it genuinely looked mysterious. Before any explanation arrived, the natural guesses were meteor, comet, or something unidentified, and the first posts reflected that confusion. Second, it was shared geography: this was not one town's curiosity. When viewers in Florida, Georgia, the Carolinas, Pennsylvania, and New Jersey are all posting the same glowing shape at the same time, the story quickly becomes a collective moment rather than a local one.

Third, it photographed beautifully. A dark sky, a bright plume, and a coastline or skyline underneath is exactly the kind of image people save and resend. Reports described dozens of viewers sending photos to local newsrooms in North Carolina, and a Getty photographer capturing the plume from Hoboken as it passed near lower Manhattan — proof of just how far the view stretched.

Key facts at a glance

• Launch time: 6:33 a.m. ET, Tuesday, October 13, 2026
• Launch site: Launch Complex 40, Cape Canaveral Space Force Station, Florida
• Rocket and spacecraft: SpaceX Falcon 9 carrying a Cargo Dragon
• Mission: CRS-35, SpaceX's 35th NASA cargo resupply flight
• Cargo: More than 6,300 pounds of supplies and science for the International Space Station
• Booster: Returned to Landing Zone 40, with sonic booms heard in Brevard County
• Next step: Dragon is scheduled to dock with the station around 11 a.m. on October 15, at the zenith port of the Harmony module

What's next

The viral moment is already over — the plume faded as daylight arrived — but the mission is not. Dragon is now on its two-day journey to the station, where it is due to dock on Thursday, October 15. That arrival will get far less attention than Tuesday's glowing sky, which is part of the charm here: a routine, reliable cargo run became a spectacle simply because it left at exactly the right minute.

If you missed it, do not worry too much. Predawn and twilight launches from Florida's Space Coast produce this effect regularly when skies are clear, and predictors now even flag likely “jellyfish” launches in advance. Next time your feed fills with a glowing cloud at dawn, check the launch schedule before you check for meteors — odds are, a rocket got there first.

FAQ

What was the strange light in the sky on October 13, 2026?
It was the exhaust plume from SpaceX's CRS-35 Falcon 9 launch from Cape Canaveral at 6:33 a.m. ET, illuminated by sunlight high in the atmosphere while the ground was still dark.

Why is it called a space jellyfish?
Because the sunlit plume expands into a bright, rounded cloud with a widening tail, resembling a jellyfish. The effect is most common for launches shortly before sunrise or after sunset.

Where was the SpaceX jellyfish visible?
Sightings and photos were reported across Florida and much of the East Coast, including Georgia, the Carolinas, central Pennsylvania, and the New York City area.

When will the CRS-35 Dragon reach the space station?
It is scheduled to dock around 11 a.m. ET on October 15, carrying more than 6,300 pounds of supplies and science to the International Space Station.
