Story summary

On Monday morning, SpaceX launched its massive Starship rocket from the Gulf of Mexico near Brownsville in its first orbital mission. During the livestream, viewers spotted a mysterious pale blue light with a brighter white tip trailing behind the spacecraft about seven minutes and 55 seconds into the flight. Social media users speculated widely about what they saw, with some suggesting it was an alien "mother ship" or a NASA satellite. However, Dean Scott proposed that the object was actually gas left over from the Super Heavy booster's engine shutdown moments before, which then became visible as Earth's horizon darkened the background. This sighting sparked intense discussion online despite SpaceX not officially addressing the phenomenon.
