Three images of Saturn from top to bottom: First, a standard RGB color image showing the rings nearly edge-on at about a 30 degree angle. Middle, a black and white image similar to above, but a little sharper taken with a filter that allows only wavelengths longer than 850nm. Lastly, at bottom, the rings seen as starkly white and the planet dark. This is a very narrow wavelength range of about 20nm centered on 889nm where methane absorbs light, making Saturn itself appear dark and the rings bright.

Been imaging Saturn while its rings are nearly edge-on and tried some infrared filters. At this 889nm methane band, Saturn strongly absorbs light, whereas its rings scatter equally across wavelengths.

Also a good visual demo of how astronomers measure exoplanet atmospheres!

It’s a giant cinnamon bun, and can confirm it is delicious. 😋

It’s the Swedish holiday, celebrated every Oct 4th, Cinnamon Bun Day! Can highly recommend with coffee or tea…or by itself.

Korvapuusti cinnamon rolls

Happy korvapuustipäivä from Finland

Woah, Impressive! Those look delicious!😋

Three quarters remain of a gigantic Swedish cinnamon role.

Happy Kanelbullens Dag to all who celebrate!

@astrojoe.bsky.social Your WR star is looking pretty good in JWST.

Today in "everything is connected if you pull hard enough".

ADS has given astronomy THE BEST literature tools available anywhere. I almost never have to use the garbage that other academics have to suffer through (GoogleScholar, JSTOR, LexisNexis, WoS, PubMed...)

Literally anytime I have to interface with those tools I weep

All of the above, and sign up for a winter race somewhere nice (even if it’s local). :)

A small crowd with Palestinian flags on a We’d night in front of Bastion of Saint Remy. Two majestic flights of stairs zig and zag to a triumphant arch seen against an evening sky. The arch is illuminated in red.

From the traffic circle in front of Bastion of Saint Remy. The arch is illuminated from underneath in red and a long Palestinian flag draped from the top of the stairs. Setting is late afternoon. In the foreground are bushes with red flowers on the traffic circle.

At night, a large crowd wearing and carrying various flags including Pace, and Palestinian flags in front of Bastion of Saint Remy. The arch is illuminated from underneath in red and a long Palestinian flag draped from the top of the stairs. A band plays on the landing of the stairs.

After the nationwide protest in Italy on Monday, we’ve continued to witness evening demonstrations in Cagliari in support of Palestine. Photos from Wed and Fri night. 👏

A collection of soda cans in a flower box outside a front door. The flower boys also has small plants and an insect hotel. The cans are red on top and say “Gaza cola, extending to a Palestinian glad down the front of the can.

The outside of the old fortifications of the medieval town Castello are lit by flood and city lights. The stone wall is light it’s color and a bit eroded with age, but several stories tall.

Lightning over the sea, seen from the top of the Castello. A hormonal bolt of lightning illuminates layers of clouds.

An old Roman amphitheater seen in low light at night. The hillside above is lined with trees and a couple street lamps.

Looking up the outside of the limestone walls of one of the old prison towers on the Castello. There is an elephant on a small pedestal part way up the way. The light limestone walls extend up against a dark night sky.

Cagliari by night, with a thunderstorm in the background is very picturesque.

Beautiful sunrise run to the beach in Cagliari. Stunning. Shout out to Efisio who captured the moment of us just chatting. www.tiktok.com/@ilmareinsar... Such an incredible place!

I get that the news cycle is packed right now, but I just heard from a colleague at the Smithsonian that this is fully a GIANT SQUID BEING EATEN BY A SPERM WHALE and it’s possibly the first ever confirmed video according to a friend at NOAA

Square-ish fortress with rounded corners on top of an isolated grass hilly with steep sides. The white stone walls are windowless and the fortress stands formidably with blue sky and puffy clouds in the background.

Ooo, know that hill though: just went to York for the first time last week! Still sits outside the old city walls, although the city has expanded around it.

Spiky plant stems in a black vase on an out of focus wood table next to out of focus glasses.

Chair legs (not even whole chairs) cast shadows on light wood floor.

Same as first picture: now plant out of focus. Whisky glass in focus.

Back on Swedish Hemnet for kicks, and the information-less real estate photos never cease to amaze. At least I feel a sense of calm while you waste my time and data.

As you cancel streaming services, here is a casual reminder that only 16% of Americans read for pleasure anymore, and your local library has hundreds or thousands of books you haven't read.

They would love to see you stop by and renew your library card.

This was from banning trans girls from girls sports. Just so you understand the reality of what's going on here.

Organ sits above the King Screen which is flanked by the enormous gothic arches of white stone inside the cathedral. There are 15 kings, with 7 on the left and 8 on the right so the arch to the choir is off center, as is the organ, compared to the rest of the building.

View of the organ from the choir, looking towards the front of the cathedral. The choir is dark wood and elaborately carved. The arch to the choir is off center, as is the organ, compared to the rest of the building.

Wide angle view inside the chapter house off the north of the cathedral. An octagonal room surrounded on all sides by tall stain glass windows and topped with an impressive arched, painted roof. The tiles on the floor are also laid out in beautiful patterns.

Ceiling of the cathedral. The tops of the stain glass windows are visible, flanked by arches of white stone. Across the ceiling, the intersection of the arches and supports are capped with gold hubs, each uniquely patterned.

Discovered the majesty of the York Minster cathedral last weekend. Also noticed that some architectural elements are very slightly off center. 🤔

The top of the Bluesky settings page has a new (for my account) blue box that says “The laws in your location require you to verify you're an adult before accessing certain features on Bluesky, like adult content and direct messaging. Learn more in your account settings.”

In the UK for the weekend. 🙄

Anyway, Signal still works and the countryside is beautiful.

The Effelsberg telescope is big. No, seriously big.

Just a reminder to check for your name in this list of books that OpenAI trained from. If your name is there, they probably owe you several thousand dollars.

It would be a shame if the group trying to remove Native Hawaiian preference from
Kamehameha Schools was spamed with negative feedback for being Anti-Indigneous because we support Hawaiian Sovereignty...
