Great “Space Jellyfish” lit the sky United State And a mystery was born among the people who managed to see it. effect was due to launch SpaceX Falcon 9 rocket From the Kennedy Space Center in FloridaTwitter users shared the amazing photos. In addition, there were those who made memes and even Compare it to the mascot of the World Cup in Qatar.
The being glowed in the dark sky and flew over the city with an expanding head and tail.
Professor of aerodynamics and mechanical engineering at the University of Texas, Chris Coombs, rated it as Space jellyfish of its own shape.
As Coombs explained, it is not uncommon for this type of phenomenon to occur every time a projectile of this pattern is ejected from the ground. visible celestial body It is the result of a combination of physics and optimal environmental conditions.
Thus, the shape of the space jellyfish simply corresponds to To the exhaust exiting from the nozzle of a SpaceX Falcon 9 rocket engine. The nozzle is a bell-shaped structure that can be seen at the end of a space rocket, and its function is to obtain the thrust for launch.
In addition, the exhaust can be seen exiting the nozzle in this characteristic way due to the difference in pressure within this structure compared to atmospheric pressure and the consequent compensation made to balance said pressures.
In this way, Coombs argued that the exhaust pressure at the nozzle is higher than atmospheric pressure and, therefore, is “low expansion”; When the exhaust leaves the missile, it expands automatically to reduce its pressure to atmospheric pressure.
So by equalizing the exhaust pressure at its outlet, a The effect of “fan” expansion Which prefers to expel the single exhaust shown in the video.
The memes behind ‘space jellyfish’ photos
After photos of the phenomenon spread, dozens of Twitter users started joking about the reason for this strange number.
One of the tweets pointed out the resemblance to Qatar World Cup 2022 mascot for a defect. “Those from Qatar are trying small things…everything is fine.”
Another also commented on the scene in which Mufasa, Simba’s father in the movie The Lion King, remembers him talking to him from heaven.
And without a doubt, the folklore of Argentine football was not left out either. Associate a user with “Ghost B” Which flew over the Bombonera a few years ago while playing the Super Clasico.
