Check out this amazing story (to me, anyway) of a 1000-mile-long cloud that consistently forms and disappears on #Mars. As a climate and water scientist, this fascinates me. www.livescience.com/space/mars/1...

1,000-mile-long cloud that forms and vanishes on Mars every day obeys 'exotic physics' never seen on Earth
New simulations suggest that the perplexing Arsia Mons Elongated Cloud (AMEC) repeatedly emerges in the Red Planet's skies thanks to a never-before-seen meteorological process.

The Sunset of September 27, 2026 was an epic spectacle whose intensity and beauty were memorable. The cloud ceiling had a wide opening toward the West that admitted Sunlight which underwent progressive color changes as it briefly in turn illuminated layers of otherwise invisible cloud textures.
The Sunset of September 27th, 2026 was one of the greatest visions the sky has ever opened up and revealed to me. It was a sunset like few I can remember in many years. I knew early on what was likely as a heavy cloud ceiling was opening up far to the West with the underside textures in that part of the cloud ceiling catching the light early on from the distant sunlit clouds.

  Vast connected cloud formations were in turn bathed in the last sunlight which progressively turned from a golden to orange to very red, in as pure a spectral filtering of Sunlight as I can recall seeing. One layer of cloud formations after another caught the light as the rays steadily angled upwards. The most distant yellow gold clouds were dazzling, like incandescent molten gold that defied photography. Lower layers were bathed in the reddest light that contrasted in hue with the more orange colors in the illuminated parts of the broken cloud ceiling above. Wide areas of the field of view were thus illuminated, appearing and fading one after the other like a parade of vast apparitions coming and going.

 The last lit clouds gave up their lurid radiance reluctantly and with a very red final flourish. But the brilliance was still happening, withdrawing beyond the Western horizon as Earth's rotation carried us into the realm of the night. The Sunset lit clouds far away were still in itself illuminating clouds nearby. From their altitude the brilliance and colors along the horizon hundreds of miles away dominate the ambient lighting. This brought an extended 'echo' of the Sunset as every cloud surface facing West shone with that fading lurid glow, like a long slowly fading piano note after a great symphony. 

 I have seen many hundreds of Sunsets and sunrises, but something about this one struck me as almost like a kind of religious experience. Awestruck wonder and numbly bathing in the experience while periodically trying to preserve a visual record.An all sky frame of the Sunset of September 27, 2026. Canon 6D with a fisheye lens. I now shoot most such sequences aimed straight up to show the entire horizon. Unfortunately due to a technical issue this became the first frame of the time lapse sequence, but I did get the extended 'afterglow'.

NASA picture of the day today is a real 🏴󠁧󠁢󠁳󠁣󠁴󠁿beauty! This is a composite image of the ~5000yo Callanish Stones on the Isle of Lewis. The amazing Giuseppe Petricca has only gone and photographed the Sun at noon there, every few days, for a whole year. #Dedication 🔭🧪👌 ℹ️: science.nasa.gov/image-articl...
The imposing Callanish Stones stand talk with their shadows spanning out across the glass.  It's a super clear sky, but looks cold. Above the central stone is a strange figure-of-8 shape of dots.  This is the location of the Sun, at noon, on various different days across the year.
