      Here is a blue jet-sprite photographed by my crewmate Butch Wilmore in a timelapse sequence. Blue jets and sprites are terms that are rather loosely applied to what I like to call “upward directed lightning” (UDL). This is a rather new elusive atmospheric phenomena now extensively captured by digital cameras but still not fully understood. The tops of this UDL are around 75-80km, boarding on the fringes of space.

      Nikon Z9, Nikon 24mm f1.4 lens, 1/4th sec, f1.4, ISO 6400, cropped frame, adjusted with Photoshop by Babak Tafreshi.

      Well well, if it isn’t astro_petit with yet another awesome post!

      Keep it comming! We love it here.

      This is the coolest thing I’ve seen all year. Thank you so much for sharing!

      It looks like a red sprite/sprites merged into lightning? And if the lightning bit was directed upward, is it possible that triggered the red sprite looking things you can see coming down from higher in the atmosphere?

      I remember seeing a documentary on these things some years ago…at the time the theory was that this discharge has the opposite charge of traditional lightning (which I believe is usually negatively charged) and happen because of the electrical potential between the cloud tops and the upper atmosphere. Due to the distance travelled and lower density of air they tended to be *extremely* powerful, but also very rare

      Not sure if any of those theories still hold any water but that’s my understanding of this phenomenon

      wow looks amazing also do we have any videos of the same available ?
      Also thankyou for posting.

      How often do these happen? Is this a one in a million shot or are they understood well enough to capture relatively easily?

      Wow! I’m in awe of both the picture and that you’re currently in space right now! Thank you so much for sharing

      Space dust in a density higher than expected?.
      This type of dust may contain elements with a charge of energy which interaction with clouds at high altitude creates these blue jet-sprite.

      And so, that’s my contribution to science today. Thanks

      I just watched your interview with Destin Sandlin about photography in space. This is incredible! I hope you catch a sprite directly overhead in the Cupola soon! Thanks
