Not all rings are forged in fantasy, my precious!  For astronomers, they are found in space. This image shows debris discs captured by ALMA around stars. The two at the top-right told astronomers something very interesting. Find out what here: https://www.eso.org/public/images/potw2603a/ 🔭 🧪

Let’s check in on the solar cosmic ray count at Mawson station following the big CME event and everything looks norm— Oooooft. 🔭

Did you know the sound of popcorn popping isn't caused by the cracking of the corn kernel? For #NationalPopcornDay, here's a portion of popcorn science 🍿 www.compoundchem.com/2017/01/19/p...#NationalPopcornDay #ChemSky 🧪

When you work in a science lab you can often be called a Lab Rat. Most people wear it as a badge of pride. I came across this small zippered bag on Amazon as a Haul penny day deal and couldn’t resist. 😁 Will use it to carry small tools for my trips to my local makerspace. #chemsky

🧪 New optics blog post! What is an optical caustic? skullsinthestars.com/2026/01/16/w...

OMG! Do it!

The Cape Fear River for me.

As much as I WANT this to be a magic portal to a happier world, it's not. Captured on the slopes of an Austrian ski resort, it's a LIGHT PILLAR, an optical phenomenon created by the alignment of hexagonal ice crystals reflecting a strong light source in a way that creates the illusion of a pillar.

After following all the ICE fuckery being shown here on Bluesky, the quote line at the end hit hard.

In happier news, it's been a great week for learning strange new things about the universe. A few highlights: The Rubin Observatory opened its eyes & immediately discovered 1900 asteroids, including the fastest-spinning large asteroid (once every 1.88 minutes!). 🧪🔭 noirlab.edu/public/news/...

Our Solar System is orbiting the center of our Galaxy at about 220 km/s so in 2025 we collectively traveled something like 7 billion kilometers across the Milky Way. Once in a while, when you have a moment, it’s worthwhile to take a look around, see where you are, and appreciate how far you’ve come.

Good morning and Happy New year! Beautiful sunrise from the first morning walk of the year with the doggo. #sunrise

Got to play with the new 30W MOPA fiber laser at my local makerspace. This thing rocks and opens up so many more making opportunities. Engraved and cut out the makerspace logo from 0.5mm thick brass sheet. #Making #lasercut

Not now, super-massive runaway black hole!

Three ways of looking at the iconic Christmas Tree Cluster, 2700 light years from Earth. What the universe looks like depends on how we look at it. These views highlight infrared (left), x-rays (middle), and red emission from hydrogen gas. Beautiful in three different ways. 🧪🔭

So love wobbegongs. Everything is good about the wobbegong. Its name. Its flattened Oscar the Grouch face. Its frondy bits. Its lazy life as a hungry rug. And it’s a shark. Outstanding animal 10/10

On FB, Yukon Geological Survey posted some spectacular photos of landslides & snow avalanches triggered by the magnitude 7.0 earthquake on Dec 6 in the St Elias Mountains. Here are some of my favs. @geocron.bsky.social @theronfinley.bsky.social @davepetley.bsky.social @ksvenenvig.bsky.social 🧪⚒️

Whoa!

Fascinating story. Seems to me there should be technology to find the device.

😆❤️ but also 😬💀 (The short of it is that HF is very deadly if you get enough of it on your skin. Nasty chemical burn but more insidiously it can bind to calcium in your body which can cause, among other things, your heart to stop. 😳) #Chemsky

Luna - watercolour and acryla gouache on paper A personification of the night sky. One of my favourite paintings. It makes me miss personal work. Eventually I'll figure out a balance where I can paint just to paint again. Prints are on INPRNT if your mom would like one for xmas

This morning we had to make the hard decision to have our 14yr old cat Romeo put to sleep. Made him a little memorial by laser engraving a piece of slate. RIP little guy. #CatsOfBluesky #LaserEngraving

I went to several box stores around town to pick up a few things this afternoon since it was Black Fri. I asked employees at each store how busy it had been. They all said "it was just steady, not like last yr when it was mobbed." Makes me wonder what that says about the state of the economy. 🤔

Utterly indeed. 😅 "we obtain Γ ∼ 10^−18 events per year, which is utterly negligible".

Looking for good news, I found this: If you were struck by a microscopic black hole, the mass of a small asteroid, it'd be no worse than a gunshot. And such black holes are definitely too rare to have "any observable effects on the human population." 🔭🧪 www.sciencealert.com/what-if-a-ti...

Predictably, the narwhal situation has escalated. 🧶

Giant cardioid: version 2.5. Version 1.0 was made using Pex tubing and grommet tape. Version 2.0 was made from laser-cut pieces. The wood was too fragile, and it broke during construction. In version 2.5, I made the pieces wider and I used thicker wood. Success, I'd say! The diameter is about 5 ft.

Whoa!

Interesting, just goes to show you that you should remain skeptical of initial reported information as often as not, it will likely contain incorrect facts. Don't just jump to preconceived biases. In this day and age information spreads so quickly that it is both a blessing and a curse.
