A unusual cloud formation was spotted in the sky early Tuesday morning. This phenomenon, known as a "jellyfish cloud," was caused by the SpaceX Falcon 9 rocket launch. The cloud is also referred to as a noctilucent cloud and is visible during certain rocket launches.

It is formed when the rocket's exhaust expands in the upper atmosphere and is illuminated by rising sunlight at high altitude. This effect only occurs during launches that take place near sunrise or sunset.

Further information about this event is available from the source, including details about the launch and the conditions necessary for the "jellyfish cloud" to appear.
