Alchemy
Tanglefoot, Australia’s only cold-weather deciduous species, attracts thousands to witness ‘the turn’. However, few will have seen them glowing in gold tones. The organism emits garish colours in response to UV light in a process called bio-fluorescence. This particular evening brought subtle aurora and airglow, a rare synergy in these forests.Photograph: Benjamin Alldridge/Australian Geographic

Earth's atmosphere with airglow over Southeast Asia at night, with a sprite above tropical thunder clouds.
Airglow at night is continuous high altitude air gas optical emission, releasing energy that had been accumulated during the daytime.
Sprites are transient (brief) electric/optical discharges from plasma in the atmosphere above thunderclouds.

Greenlight for next two ESA #Scout missions, Hibidis and SOVA-S: https://www.esa.int/Applications/Observing_the_Earth/FutureEO/Greenlight_for_next_two_ESA_Scout_missions - the latter is "Satellite Observation of Waves in the Atmosphere – Scout" with a shortwave infrared imager to provide near-global daily observations of #GravityWaves at an altitude of between 80 km and 120 km by measuring the intensity of #airglow, a faint emission of light produced by a chemical reaction in the atmosphere.

Standing on the Shoulders of Giants
This photograph comes from the heart of the Sierra La Giganta in Baja California Sur, Mexico, following a two-day expedition from the small village of San Juan Londo. The final approach required an ascent of more than 800 metres by mule along a long-forgotten section of the historic Camino Real, once used by vaqueros and their donkeys to transport goods between remote settlements.

Atmospheric glow, often referred to as #Airglow, is a faint emission of light by a planetary atmosphere caused by chemical reactions triggered by solar radiation during the day.
Unlike the aurora, which is driven by high-energy solar particles hitting the poles, airglow occurs across the entire sky and is most visible from space as a thin, luminous bubble wrapping the Earth.

#PhotoOfTheDay: #MilkyWay and #Airglow
The Milky Way stretches below the curve of Earth's limb in the scene that also records a faint red, extended airglow.
The galaxy's central bulge appears with starfields cut by dark rifts of obscuring interstellar dust. The picture was taken by Astronaut Scott Kelly in August, 2015, the 135th day of his one-year mission in space.

#Airglow is a faint, natural emission of light in Earth's atmosphere that prevents the night sky from ever being completely dark.
It occurs when gas molecules, energized by solar radiation during the day, release that energy as a subtle, colorful glow.

#PhotoOfTheDay: #Aurora, Meet #Airglow
Two of Earth’s most colorful upper atmospheric phenomena, #Aurora and #Airglow, met just before dawn in this photo shot by an astronaut on the International Space Station (ISS).
Wavy green, red-topped wisps of aurora borealis appear to intersect the muted red-yellow band of airglow as the ISS passed just south of the Alaskan Peninsula.

#Airglow is a faint, steady emission of light from a planetary atmosphere, caused by atoms and molecules in the upper atmosphere releasing energy they absorbed from sunlight, primarily through photochemical reactions.
This phenomenon causes the night sky to never be completely dark, and unlike the aurora, it occurs at all latitudes and at all times, though it is often too dim to be seen without long-exposure photography

Astronaut Don Pettit took this photo from space in January 2025, as the Sun began to rise over a cloudy Pacific Ocean. This long-exposure image shows off the wide band of the Milky Way, our home galaxy, above the aurora and airglow that shine closer to Earth's horizon.

Colorful Airglow Bands Surround Milky Way
Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however -- like an approaching storm -- may cause noticeable rippling in the Earth's atmosphere. These gravity waves are oscillations in air analogous to those created when a rock is thrown in calm water.

Comet A6 Lemmon on the evening of 25 October.
The blue ion tail has breaks and kinks, thanks to the solar wind and reversals in its magnetic field.
The broad, yellowish, shorter dust tail is at a different angle than the ion tail.
This is a stack of 76 30-second exposures, aligned on the comet's nucleus. This makes all the stars to be short trails.
In individual exposures the sky background was banded because of airglow. Fortunately that problem was averaged out when all the frames were stacked and combined.

Comet C/2025 A6 Lemmon in the evening sky, as seen in the mountains of southern New Mexico.
First photo was taken in twilight, so the sky is blue. This comet is not very bright, so the faint extensions of the tail are easily washed out by twilight (or light pollution).
Second photo is a slightly wider view, taken in full night. The tail extends at least seven degrees. The sky background is mottled and banded. That's because bands of (mostly green) airglow were drifting across the sky.
The third photo shows the appearance of the second photo before I took steps to try and smooth the sky background. With contrast set high, not only was the sky covered with bands of lighter and darker sections of sky...but they were different colors as well.
The fourth photo shows where I placed sample areas across the frame so that image processing software could analyze, model, and correct the irregularities in the sky. Considering what I started with, my final result is pretty good.

I sometimes try to capture #NightScape scenes in #TerraNovaNP campground (Newman Sound) that folks might find recognizable. And perhaps the park might find useful for promotional purposes.
Pretty happy with how this one turned out. Even captured some #Airglow.
This was captured later in September. Might not have been possible earlier in the season as the park still has work to do addressing #LightPollution generated by "uninformed" campers.

#Airglow is a faint, continuous emission of light from a planetary atmosphere that causes the night sky to never be completely dark.
Unlike auroras, which are driven by solar wind particles and are typically localized to polar regions, airglow is caused by day-to-day solar radiation exciting atmospheric molecules and occurs everywhere on Earth.

Saturn Opposite the Sun
This year Saturn was at opposition on September 21, opposite the Sun in planet Earth's sky. At its closest to Earth, Saturn was also at its brightest of the year, rising as the Sun set and shining above the horizon all night long among the fainter stars of the constellation Pisces.

Southern New Mexico has entered the chat.
Red auroral glow was barely visible just above the horizon around 10PM local time...needed 30-second exposures, f/1.4, ISO 400.
But what surprised me more was the green airglow. It was bright and had texture/detail. These two images (processed to better show the lumpiness of the sky background) show the green airglow 'clouds' drifting north over time.

#Airglow is the faint, diffuse emission of light by a planet's atmosphere, causing the night sky to never be completely dark.
This phenomenon occurs when atoms and molecules in the upper atmosphere, energized by sunlight during the day, release that stored energy as light at night.

Colorful Airglow Bands Surround Milky Way
* Image Credit & Copyright: Xiaohan WangExplanation:
Why would the sky glow like a giant repeating rainbow? Airglow. Now air glows all of the time, but it is usually hard to see. A disturbance however -- like an approaching storm -- may cause noticeable rippling in the Earth's atmosphere. These gravity waves are oscillations in air analogous to those created when a rock is thrown in calm water. Red airglow likely originates from OH molecules about 87-kilometers high, excited by ultraviolet light from the Sun, while orange and green airglow is likely caused by sodium and oxygen atoms slightly higher up. While driving near Keluke Lake in Qinghai Provence in China a few years ago, the photographer originally noticed mainly the impressive central band of the Milky Way Galaxy. Stopping to photograph it, surprisingly, the resulting sensitive camera image showed airglow bands to be quite prominent and span the entire sky. The featured image has been digitally enhanced to make the colors more vibrant.https://apod.nasa.gov/apod/ap220313.html

From the Northern to the Southern Cross
* Image Credit & Copyright: Nicholas Buer
https://www.nicholasbuer.com/Explanation:
There is a road that connects the Northern to the Southern Cross but you have to be at the right place and time to see it. The road, as pictured above, is actually the central band of our Milky Way Galaxy; the right place, in this case, is dark Laguna Cejar in Salar de Atacama of Northern Chile; and the right time was in early October, just after sunset. Many sky wonders were captured then, including the bright Moon, inside the Milky Way arch; Venus, just above the Moon; Saturn and Mercury, just below the Moon; the Large and Small Magellanic Clouds satellite galaxies, on the far left; red airglow near the horizon on the image left; and the lights of small towns at several locations across the horizon. One might guess that composing this 30-image panorama would have been a serene experience, but for that one would have required earplugs to ignore the continued brays of wild donkeys.https://apod.nasa.gov/apod/ap140127.html

A Dark Sky Over Sequoia National Park
* Credit: D. Duriscoe, C. Duriscoe, R. Pilewski, & L. Pilewski, U.S. NPS Night Sky ProgramExplanation:
Scroll right to take in the view from the highest summit in the contiguous USA. The above 360-degree digitally stitched panorama, taken in mid-July, shows the view from 4,400-meter high Mt. Whitney in Sequoia National Park, California. In the foreground, angular boulders populate Mt. Whitney's summit while in the distance, just below the horizon, peaks from the Sierra Nevada mountain range are visible. Sky sights include light pollution emanating from Los Angeles and Fresno, visible just above the horizon. Dark clouds, particularly evident on the image left well above the horizon, are the remnants of a recent thunderstorm near Death Valley. High above, the band of the Milky Way Galaxy arches across the image left. Bright airglow bands are visible all over the sky but are particularly prominent on the image right. The planet Jupiter appears as the brightest point on the image left. A discerning eye can also find a faint image of the far distant Andromeda galaxy, a satellite trail, and many constellations. Today marks the 100th anniversary of the completion of the historic stone shelter on Mt. Whitney, visible toward the image right.https://apod.nasa.gov/apod/ap090827.html
