Starting this Friday, four separate #JWST programmes will be exploring physical processes in Jupiter's atmosphere and ionosphere. We're asking amateur astronomers to help provide context imaging over the next few weeks to understand how the atmosphere is changing with time. #planetaryscience

Comet 29P

Comet 24P

Here are the results of my S50 first light. Mediocre conditions, I would've struggled visually. Both images stacked on the comet.

29P/Schwassmann-Wachmann in continuing outburst with expanding asymmetrical coma, 11.6 mag, 1.8', 44x20 sec

24P/Schaumasse, 10.7 mag, 3.1', 242 x 10 sec.

8x10” oil painting of Jupiter’s Great Red Spot with a rectangle of ultraviolet light and a rectangle of infrared light

If you like space, science, and art …you’re in the right place!

Spectrum of Storms: Jupiter in visible, ultraviolet, and infrared painted in oils

My first #SolarCan experiment! The Solar Can was mounted on a pole in our garden and left for 368 days, where photo paper was being exposed to the Sun via a pinhole. The paper was removed, scanned, inverted and processed to give this final image.

Me standing next to my easel, which is holding a 24x24” oil painting. 5 vertical rectangles are colorful in oranges and blues. The rest of the piece is in greyscale. 🐡🔭🧪

Behold! My latest multi-spectral oil painting. The Cat’s Paw Nebula in visible light (greyscale) & infrared (rectangles) featuring 2027 hand-painted stars ⭐️

Waning Gibbous Moon 62.8%

Silly o'clock (04.30) and I was up taking Moon photos (as you do). Here's what I took (as I did)! #astronomy #astrophotography @stormhour.com @photohour.bsky.social

Messier 45 (M45), famously known as the Pleiades or the Seven Sisters, is a bright open star cluster located in the constellation Taurus. It is one of the closest and most recognisable objects in the night sky, easily visible to the naked eye as a tight group of stars resembling a "tiny dipper".

The Pleiades (M45). One of my favourite night sky objects. I collected another hour of data this evening so here's a mega stack of nearly 5 hours collected in 2026. #astronomy #astrophotography @stormhour.com @photohour.bsky.social

Glad you like it! It was a very atmospheric night. I was reminded how fast conditions can change, even on an apparently still night, 10 minutes later there was no halo and the tree-line and spire weren’t visible from there

Night scene. Foreground fields and hedgerows, some trees distinguishable in the middle distance amongst the mist. Church spire breaks the horizon on the right. Sky largely overcast with thin cloud, bright, nearly full (waxing gibbous) moon left of centre surrounded by a '22° lunar halo'. Jupiter appearing in a less cloudy area in the top right as a bright star-like spot.

Murky view tonight

Full moon nearly fills frame

Tonight’s full moon.

#Fujifilm X-T4, XF150-600mm

The silhouetted branches of a tree against a cloudy night sky. The moon and star-like Jupiter peek through a gap in the clouds. The clouds are iridescent with their light. Reminds me of you.

The Snow Moon, a little early. It's closer to full when it rises tomorrow, but I'm not sure it will be clear. #Astronomy #Astrophotography

A very nearly full Moon with bright impact craters and smooth, dark lunar plains.

The Moon tonight is very nearly full (99.3%). 🔭

Aw thanks!! Yea, Jupiter

Night scene - streetlight is in the centre (it is not on/illuminated), with the lamp covering the moon, in the sky a large circle ‘halo’ circles the image, almost to the edges, it has subtle spectra, primarily just appearing as a bright white circle. Some clouds intrude into the halo in the top right, and Jupiter appears as a bright white star-like point of light at the 2 o’clock position.

22° lunar halo from earlier this evening

Good evening from London. Tons of clouds but a shaft of light is bursting through. Will be a full 'Snow' Moon tomorrow #astronomy #astrophotography @stormhour.com @photohour.bsky.social

Another moon shot from a few nights ago.
Sinus Iridum at sunrise.
I love the long shadow cast by Cape Laplace. The mountains at lower right, known as the Straight Range, are also interesting
🔭

a close up high resolution image of the moon showing craters, mountains, and maria. Best 30% of 1474 frame 180s video taken with Orion ShortTube 80 telescope and ZWO ASI178MM camera, stacked with Autostakkert and processed with Registax and Photoshop.

I have had my Orion ShortTube 80 refractor for 30 years. I used it a lot in the 90s with a film camera. Now it is relegated to guide scope duty attached to a ZWO ASI178MM camera. Last night I let them show what they can do on the waxing gibbous moon. Not bad! Details in ALT. #astrophotography

a flooded impact crater on the moon. One side is completely submerged while the other forms a arc of mountains. Taken with a Meade 8" SCT with a 2x Barlow and ZWO ASI662MC camera. The best 30% of a 3118 frame 180s video were stacked with Autostakkert and processed with Registax and Photoshop.

Another target from last night, Sinus Iridium, the Bay of Rainbows. It is a large impact crater that has been flooded by basalt flows. Bianchini is the large crater in top center. Some wrinkle ridges can be seen and the crater Laplace A looks lonely out in the bay. Details in ALT. #astrophotography

My attempt on Maffei 2 - a pretty sizeable disk galaxy, but hidden behind the Galactic dust curtain - so only very few images can be found on astrobin. I had to stretch it rather aggressively to get the faint structure show up prominently. bit.ly/4lB3t68 🔭#astrophotography 🔭📷

Construction paper art of space shuttle leaving earth with the Moon in the distance and stars. The black paper background is 4 different shades. The whole piece is taped and stapled to a piece of cardboard.

Made with paper and an empty toilet roll. Will be a future painting reference 💚⭐️

Love this Rami!! Always appreciate some Rupes Altai, well illuminated in your capture!

Monochrome photo of a crescent moon.

Our celestial neighbour, right now, from my backyard. SeestarS50 capture. Monochrome.

That prominent central crater is Theophilus.

It’s about 4km deep and 100km wide.

In its centre is a triple peak mountain that gets to about 2km high.

Mountains on another world, formed by an impactor.

🌙🔭

This is really beautiful and gives a sense of altitude and column height.

[alt-text: a person standing on a snow field with a camera and tripod in front of them. Above them, are very bright green and purple aurora borealis. These look to stretch vertically into space. Stars pepper the background.]

A photograph of rippling auroral curtains in hues of red, green and white over a silhouetted horizon which occupies a small portion of the lower frame.

A photograph of a bright and vibrant auroral curtain with red rays seen behind a scattering of backlit clouds. Silhouetted moorland hills sit at the bottom of the frame.

A photograph of a diffuse red and green auroral curtain with subtle ray structure over a misty moorland valley.

A photograph of a vibrant swathe of green and red aurora over a silhouetted moorland hillside. Clouds drifting across the middle of the frame appear silhouetted against the auroral light.

Lots of shots to go through from tonight’s incredible auroral show over Dartmoor. Here are four of my favourites so far. While the camera does see far more than the naked eye, the colours in tonight’s display were the best I’ve seen in 30 years of mid-latitude aurora watching. #NorthernLights #Devon

Seeing faint #aurora in Southeastern Connecticut right now. Hope it gets brighter.

Green beam of Aurora shoots across the sky

Absolute scenes! The #aurora has gone crazy this evening here in Wales with vivid green and red visible to the naked eye. And don’t get me started on this beam which shot overhead for no more than 20 seconds. #astrophotography #photography #northernLights

Green and red aurora over Arthur’s seat in Edinburgh

Beautiful aurora tonight! Don’t forget to look outside. Arthur’s seat in the background.
