The Falcon Nebula from SpaceX Launch CRS-23 August 29, 2021

The Falcon Nebula is a rare sight that's created when the 2 Stages of the rocket separate during a night Launch and the Booster (1st Stage) performs a maneuver called a Boostback Burn in order to either send itself back to land on the ground at LZ1 in Cape Canaveral OR, in the case of this Launch, if it's saving time in getting the Booster back to Port Canaveral so they perform the Boostback Burn & land the Booster on a drone ship in the ocean located much closer to Cape Canaveral. Seeing this NEVER gets old!

Enjoy! :)
