First cleat sky in January and there it was. The Moon.

I sat down on an inviting chair. It was midday during a warm and sunny nature walk in my garden.

This is the first Monarch Butterfly I've seen in 2021. My milkweed plants have also come back after a poor year last year.

The easiest way to understand Lagrange points is to think of them in much the same way that wind speeds can be inferred from a weather map. The forces are strongest when the contours of the effective potential are closest together and weakest when the contours are far apart.

Lagrange Contours

L4 and L5 correspond to hilltops and L1, L2 and L3 correspond to saddles (i.e. points where the potential is curving up in one direction and down in the other). This suggests that satellites placed at the Lagrange points will have a tendency to wander off (try sitting a marble on top of a watermelon or on top of a real saddle and you get the idea). But when a satellite parked at L4 or L5 starts to roll off the hill it picks up speed. At this point the Coriolis force comes into play - the same force that causes hurricanes to spin up on the earth - and sends the satellite into a stable orbit around the Lagrange point.

Not as much detail as I had hoped...

Thick grey clouds. So dark. So a little play with some oil on water. I am pretending that is the sun and planets.

These colors represent the various types of iron and mineral deposits on the Moon. The blue hues reveal titanium rich areas while orange and purple colors show regions relatively poor in titanium and iron. The white/gray tones refer to areas of greater exposure to sunlight.

Comet C/2017 K2 (PanSTARRS), currently the brightest comet in the sky. This image is from the dark and clear morning of June 30th from suburban Bloomington, Ind., with the comet against the rich star background of the constellation Ophiucus. It will be getting a little closer to Earth in the next couple of weeks and so may still be a bit brighter, but will be up against a bright, full Moon, so this may be the best I can do.

Images were combined twice, once with the stars aligned but the comet trailed and again with the comet registered but the stars trailed. These two rendered images were combined in Photoshop to produce the composite.

Reprocess of a Jupiter image from last week. Additional sharpening was applied and then de-noised using Topaz Labs de-noise which is an amazing piece of software

Far left to far right in a shallow, climbing diagonal line: Venus, Moon, Mars, Jupiter and Saturn. 0345 looking east.

This from 6 45 s SER files taken with a ZWO ASI224MC camera with 3x Barlow and a ZWO UV/IR cut filter through the C14 at Cerritos College. I used FIreCapture to take this data. SER files were used to create stacks of the best 26% of frames in AutoStakkert, and those stacks were processed in PixInsight. The resulting images were registered and derotated in WinJUPOS, with the result undergoing some final tweaks in GIMP.

Acidalia Planitia and Chryse Planitia are visible on the left side of the northern hemisphere below the north polar cap. There appears to be some weather just south of the polar cap toward the limb of the planet.

Venus conjunction with Crescent moon on 09 Oct 2021 in Scorpius constellation. However, Venus is paired with star called Dschubba. In this image, planet Venus is about 3 arc degree from the 3 days old Moon. Also, you can see the Earthshine on the Moon’s dark side with 9% illuminated crescent.

It was really fun capturing this year’s blood moon. I wasn’t expecting to see it due to the back to back storms we’ve been having, but Mother Nature was kind and moved the clouds for about an hour so we could enjoy it! I wish I’d captured it rising over something interesting, but I still think it’s mesmerizing by itself surrounded by the night sky.

‏Jupiter opposition on 26/09/2022 with its closest approach to Earth by about 150 million km with . apparent diameter of 50 arc second. Jupiter currently is about 590 million km from Earth. The image shows Europa , one of Jupiter moons on the left of the planet. This closest approach will happen again after 59 years.

Exploration reveals that our solar system is filled with amazingly diverse places that transform our understanding of Earth and worlds beyond.

The Kenneth C. Griffin Exploring the Planets Gallery probes the science and history of our exploration of planets and moons. This exhibit tells the stories of the diversity of worlds circling our Sun and how exploring those worlds helps enhance our own understanding of Earth. Exploring the Planets draws on research from scientists in the Museum’s Center for Earth and Planetary Studies, who are actively involved in current planetary missions.

This looks like a flipped version of the "Saturn's rings" photo (Photo ID: P-23883C/BW) from the NASA NSSDC Photo Gallery: nssdc.gsfc.nasa.gov/photo_gallery/photogallery-saturn.html

It was taken by Voyager 2 on July 21, 1981.

North is up. This image is derived from a single RGB run captured in Firecapture, stacked in Autostakkert, wavelet sharpened in Registax, and color channel derotated in WINJUPOS.

Seeing was Average at capture. I had hoped to stack and sharpen in PSS, but the result was disappointing. I have four more RGB captures that can be derotated and added to this data. I feel like I am missing something with PSS, which is still new to me. I'll take a deeper dive when time permits.

Ormai il pianeta Giove si allontana sempre di più dalle condizioni ideali di osservazione. Fra la fine dell'anno scorso e l'inizio di questo, ho iniziato a fare sul serio e a riprendere in mano la mia grande passione: osservare il cielo e sentirmi parte dell'Universo.

Qui Giove ripreso qualche giorno fa con una focale equivalente di 2.250 mm su un telescopio dal diametro di 15cm. Il risultato è notevole perché arriva al limite massimo teorico dello strumento

Buona giornata
