Was it a plane? Was it a UFO? Bright light over Quebec captivates stargazers
In a publication on Facebook, the Astrolab du parc national du Mont-Mégantic in Quebec's Eastern Townships described it as "a magnificent and luminous spiral streaking across the sky at around 10:40 p.m."
Several people in the Montreal area also witnessed the strange phenomenon and reached out to CBC News describing a bright light enveloped by a fuzzy halo and warning of a UFO sighting.
While it was certainly unusual, it wasn't really an unidentified flying object, but more likely the result of a rocket launch, according to the Astrolab.
"It was in all likelihood the second stage of an Ariane 6 rocket which was igniting its engine in order to de-orbit itself after having released the European satellite Metop-SGA1 in a polar orbit," the Facebook post explained.
The European Space Agency confirmed on its website that a weather satellite was launched Tuesday evening at 9:37 p.m. local time, from the European spaceport in Kourou, French Guiana — an overseas department of France located in South America.
The new satellite is meant to usher in "a new era of weather and climate monitoring from polar orbit."
WATCH | What was that bright object flying in the sky over Quebec:
According to astrophysicist Robert Lamontagne, the rocket's orbit is what allowed for the spectacle to be visible in Quebec.
Most of the time rocket launches are on an equatorial orbit and so will be visible near the equator, he said.
In a polar orbit, the rocket has to go around the earth circling each pole of the planet.
"So the the trajectory of that the rocket made it so that from our latitude it could be seen in Montreal or the south of Quebec," he said.
But to witness the phenomena, other factors also need to align, according to Lamontagne, including the time of launch and the altitude reached by the rocket.
"From our point of view, we were in the dark, the sun was low below the horizon, but the rocket itself was so high that it was still lit by the by the sun," he said.
And as the second stage of the rocket re-entered the earth's atmosphere, he said, "it was spinning a little bit, there was exhaust gases coming out from it and that's what people saw in the sky."
A spokesperson for the Canadian Space Agency told CBC News that many observers captured video of the event, with the agency confirming it was the ESA's Ariane 6 rocket.

Was it a plane? Was it a UFO? Bright light over Quebec captivates stargazers
With eyes turned to the skies, stargazers taking in the Perseid meteor shower on Tuesday night witnessed something out of this world.

Strange lights were spotted over the Twin Cities on Tuesday — here's what it may have been
A video shows a strange light in the sky Tuesday night over Woodbury, Minnesota, causing some to wonder what it may have been. Rusty Nereng, who took the video, tells WCCO he captured the unique sight around 9:30 p.m., moving from south to north with what looked like halos of light on each side. There have been other reports across the eastern part of the U.S. of the same strange light, leading to speculation of meteors, weather phenomena or, of course, the good old UFO sighting. It turns out that strange sight in the sky wasn't from the weather — but it could help us track the weather in the future. It's possible that it was actually the Ariane 6 rocket. The European Space Agency says it launched the rocket from South America on Tuesday night. It was carrying a weather and climate satellite that will orbit the Earth, sending back weather information that will aid in weather forecasting and climate monitoring, among other helpful weather services. So the strange sight in the night's sky that brought about a lot of questions is hoping to bring better weather answers for forecasters in the future.

Stargazers dazzled as spirals of light appear in night sky
Stargazers on the lookout for the Perseid meteor shower were treated to an extra nighttime spectacular on Tuesday night as spirals appeared in the sky along the East Coast. The unusual light show -- which appeared to show circling lights in the heavens -- was on display after multiple rocket launches. MORE: SpaceX loses another Starship in latest launch, with debris seen streaking across the sky Videos began circulating online in several states, including Maryland, New York, New Jersey, Tennessee, Illinois, Ohio and Nebraska, after 9 p.m. ET Tuesday, social media posts show. ABC Philadelphia station WPVI began receiving calls and messages from viewers around 10:30 p.m. to report the phenomenon, the station reported. The spiraling lights seemed to appear "out of nowhere," Blake Brown, who witnessed the dazzling display from Algonquin, Illinois, while watching for the meteor shower, told ABC News. MORE: Rare wave-shaped clouds hovering over Virginia skyline caught on camera The majority of the spiraling light sightings likely stemmed from the launch of Ariane 6, said Jonathan C. McDowell, an astrophysicist for the Harvard-Smithsonian Center for Astrophysics. That rocket lifted off from the Guiana Space Centre at Europe's Spaceport in Kourou, French Guiana, at about 8:37 p.m. ET, according to Eumetsat, a European operational satellite agency for monitoring weather. Ariane 6, about 196-feet tall, has the ability to launch both heavy and light payloads for applications such as Earth observation, telecommunication, meteorology, science and navigation, according to the European Space Agency. The appearance of the spirals in the sky was likely the result of the upper stage of the rocket tumbling as it underwent a disposal rocket firing at the end of the launch, McDowell told ABC News. MORE: Falling space debris is increasingly threatening airplanes, researchers say The spiral light occurs when reflection from sunlight interacts with the frozen plume of fuel from the exhaust of rockets. "It's a nice, perfect spiral because it's way out in space with no air to distort the shape," McDowell said. Tuesday's launch, which brought a weather satellite to orbit, is the third-ever mission for the powerful rocket, according to Another rocket, the Vulcan Centaur Rocket, successfully lifted off from the Cape Canaveral Space Force Station in Florida at 8:56 p.m. ET, according to the United Launch Alliance. The 202-foot rocket was carrying a pair of experimental navigation satellites on behalf of the United States Space Force's first-ever mission, according to "The Vulcan launched east and went to a high orbit, and was still coasting upward [without the rocket firing] when the spiral was seen," McDowell said. "If people in Florida saw something at 9:37, 9:45 pm ET, that could have been the Vulcan."
