Astronomy Picture of the Day - Launch Plume: SpaceX Jellyfish

Explanation: Even if you live with your head in the clouds, you won’t find a jellyfish like this one very often. The featured image shows a SpaceX Falcon 9 rocket launch from Cape Canaveral in Florida on March 4. The launch happened 52 minutes before sunrise, and the second stage rocket exhaust plume was high enough in the sky to catch the light of the rising sun, while the photographer was still in the dark. This combination of light and shadow, possible at dawn or dusk, makes the exhaust, mostly water vapor and carbon dioxide, appear as a glowing cloud. It only looks like it's going down, as the rocket follows the curvature of the Earth on its way to space. A related effect is the twilight phenomenon, which causes colorful contrails sometimes mistaken for UFOs. But, in case you are wondering: real jellyfish were sent to space by NASA in the 1990s as part of a science experiment.

I didn’t see this one.
But, I did see one some time ago.
It was a spectacular sight live.

Phoenix, June 2 2016 . I saw something similar in the sky from a natural event. A meteor that broke up and landed some pieces on an Indian reservation. Upon analysis it was discovered it was related to the 2013 Chelyabinsk meteor that hit Russia .

memories...

about 6 years ago I went to Boracay to kiteboard. Great place but they have sea Urchins!.. I learned the hard way when I crashed and when I stood up I stepped on 2 Urchins that were right next to each other. Made my way in to shore and as I limped in all the beach boys were telling me to pee on my foot to take, which was, excruciating pain away. so I limped to the bathroom, put my foot over the commode and pee’d on my foot. no pain relief at all. and then it hit me I was had!! I go limping out of the bathroom to be met by all of them laughing... I just nodded and waved my hands in defeat!!

37 spikes broken off in my right foot. being shell material, they just crumpled when trying to use tweezers to pull out the spikes. it took about 8 months for them to get pushed out naturally. I dont go to Boracay anymore!!
