A shadowy nebula with tints of orange, red, and blue. There are several bright, newly formed stars. Some of those stars have great jets of interstellar gas emerging from opposite ends. The jets of multiple stars are all at the same angle.

This image is the groundbreaking proof of a long believed astronomical concept.

This is the Serpens Nebula, an active star-forming region. Look closely, and you'll spot multiple stellar jets being ejected from the newly formed stars. (1/3)

I've had this in the past. This time I gave my Y11 two @1stclassmaths.bsky.social papers, with the QR codes to get to the answers. I told them what I would be checking for would be whether they had had a go and marked the papers. That way, at least they can use it like a Mock "Walkthrough"...

This App Warns You if Someone Is Wearing Smart Glasses Nearby The creator of Nearby Glasses made the app after reading 404 Media's coverage of how people are using Meta's Ray-Bans smartglasses to film people without their knowledge or consent. “I consider it to ...

NEW: A hobbyist has created Nearby Glasses, an app that warns you if someone close by is wearing smart glasses. 404 Media spoke to the creator who said he was inspired by our coverage that uncovers how men are wearing Meta's Ray-Bans to covertly film massage parlor workers.

Am I reading as much as I had hoped for this year? No. But am I at least finishing books at a faster rate than I am buying new ones? Also no.

Mathematical Miscellany #101

A compilation of mathematical goodies! It is so important that students check answers for reasonableness, yet they frequently don't. Examiners frequently report that students lose "easy" marks by providing answers that are physically or mathematically impossible.…

Got this one too!

Decided this is a better use of my Saturday afternoon #MathsToday

A circuit board with one connection made, empty LCD display connectors at the top, connectors for buttons below. A soldering iron sits next to it.

This is the circuit board. What do you think I am making? #MathsToday

A circuit board with one single element, maybe a capacitor, attached, and lots of empty connections.

Next project started. Have decided that (a) I should have practiced with a soldering iron when I was younger and (b) I need some thinner solder before going further... #HalfTerm

HST/WFC3 UVIS imaging of the runaway black hole (left) and the streak of stars left in its wake (right).

New evidence from the James Webb Space Telescope confirms that a "runaway" black hole escaped from its host galaxy and left a trail of young stars scattered in its wake! 🧪

A reminder, before a certain movie probably makes a big thing of it again:

A young Irish couple did not provide the critical data that made Stagg tell Ike to delay D-Day.

The most critical data came from HMS Hoste, alone out in the Atlantic.

The Blacksod story is nice. But it's not true. /1

The cover to"The Dispossessed" by Ursula Le Guin.

Finished. I always forget how fantastic a writer Ursula K Le Guin is, how believable her characters and worlds are. Thoroughly enjoyed this, as relevant as it ever was. #BookSky #ScienceFiction

Some people denigrate one of the greatest tools of the computer age, Excel.
They are obviously speaking out of ignorance, I myself know how to use it and would give it '10/10

Episode 2: The History of Cats on Ships by The Untitled History Podcast From as early as 7000 years before the common era, we have evidence suggesting cats served alongside humans on ships. This isn’t just in a civilian capacity. As long as there have been warships, cats ...

Problem of the Week 160!

Please do not comment the solution so others can work it out too. Instead, like this post or comment a thumbs up if you think you have the correct answer!

The solution will be posted in the comments on Thursday afternoon.

A large yellowish blob in the upper-left centre, with two dimmer dots to the lower right marked by arrows. These dots are giant exoplanets. The remaining dots without arrows are background stars, and the features around the main blob are imaging artefacts.

See those two dots with arrows pointing to them?

They're giant gas planets orbiting their star, located 307 lightyears away.

These are directly imaged exoplanets.

A book-nook model of the inside of a starship with a crystal ball sat midway up, the model kit up, and cough mechanisms around the walls and floor.

Finished! Just don't try turning the cogs... #BookNook #HalfTerm #MentalHealth

A book-nook model of the inside of a spaceship. It has lifts of gears everywhere.

A broken timepiece, part of a wooden model, with a ruler showing this is about 2 centimetres across.

You know it's serious when you have to assemble the assembly tool...😬

The picture shows the self-assembly wooden book nook kit "Doomsday Starship" with it's parts spread out.

Take a good look at this close-up of Io — the terminator slices it straight down the middle. Right side catches full sunlight and lights up in these vivid yellow-oranges. Left? Mostly blacked out, but you can still make out stuff because Jupiter's glow is bouncing off it (that's the Jupitershine doing its thing). The ground's a mess: rough everywhere, spotted with these huge volcanic sinks called paterae, plus darker smudges — sulfur gunk or silicates most likely — and patches that glow a bit brighter. Those could be fresh lava spills or just sulfur dioxide frost hanging around.

How intriguing is this view of Jupiter's rocky moon Io, the most volcanically active body in the Solar System? 🔭 🧪⚛️
