This magnificent image of the Crab Nebula (M1), by Michael Sherick, arranges broadband color data and narrowband data that trails emission from ionized sulfur, hydrogen, and oxygen atoms.

Reference➡️ apod.nasa.gov/apod/ap21122...

The Crab Nebula is the first astronomical object identified

🔭 🧪 🧵
This image features the Crab Nebula (M1), the remnant of SN 1054, a supernova first observed on c. 4 July 1054. This sharp, telescopic view combines broadband color data with narrowband data that tracks emission from ionized sulfur, hydrogen, and oxygen atoms to explore the tangled filaments within the still expanding cloud. The background of the image is black, dotted with numerous stars.

The Bubble Nebula (NGC 7635) is a fascinating celestial object spectacularly captured by Hubble.
This image was released in 2016 to celebrate HST's 26th year in space.

The Bubble Nebula in this Hubble image, also known as NGC 7635, is an emission nebula located some 8,000 light-years away.

The curious thing about billionaires defying the rule of law and the orders of the court, is that their wealth depends entirely on enforceable legal rights: contract, property, and so on.

Those saying court orders have no value need to be careful what they wish for.

"The DOGE campaign has generated chaos on a near-hourly basis across the nation’s capital. But it appears carefully choreographed in service of a broader agenda"

In chaotic Washington blitz, Elon Musk’s ultimate goal becomes clear
Shrink government, control data and — according to one official closely watching the billionaire’s DOGE — replace “the human workforce with machines.”

Bullseye! Researchers using Hubble found a massive galaxy rippling with nine star-filled rings after an “arrow,” the blue dwarf galaxy to its center-left, plunged through its core 50 million years ago. A thin trail of gas still links the pair: bit.ly/4hcX52n 🔭 🧪
A large galaxy is at center, and a significantly smaller galaxy is to its left. The large galaxy, nicknamed the Bullseye, is mostly face-on, but the top appears slightly tilted away. It has several rings. Its circular core is bright white at the very center, but light yellow overall. Going outward, there are gaps between the rings. The core is surrounded by two slightly lighter yellow rings, which also appear to be overlapping. The next ring is slightly more transparent and yellow. The two or three rings that are farther out are bluer, sometimes with blue clumps. The widest ring is also blue, but also the most transparent. At 9 o’clock is a small dwarf galaxy. It is about the same size as the yellow core of the Bullseye. The dwarf galaxy is blue, with many dots. It looks like the edge of the Bullseye might touch the dwarf galaxy. Both galaxies are set on the black background of space, which is dotted with a range of galaxies in different shapes, colors, and sizes.

It would be yet another tragic, stupid & traitorous mistake for the U.K. to fail to act in complete solidarity with the EU on this but instead do the dirty by trying to stitch something up with Trump. Trump will never be a reliable partner; the U.K. should be & with its European neighbours & allies

Trump: "The UK is way out of line and we'll see. The UK, but European Union is really out of line. UK is out of line but I'm sure that one, I think that one can be worked out. But the European Union, it's an atrocity what they've done."

Stop Musk from funding far-right politics in the UK!

I just signed this petition 'Tighten the rules on political donations' - it's nearly at 30,000 signatures - can you add your name too? -

Petition: Tighten the rules on political donations
We want the government to: Remove loopholes that allow wealthy foreign individuals to make donations into UK political parties (e.g. by funnelling through UK registered companies). Cap all donations ...

Why is the government happy to cosy up to China, but won't even look at a better customs deal with our closest neighbours in Europe?

Ministers say they’re looking everywhere for growth but are ignoring what is staring them in the face.

Powerful stuff from cartoonist Ella Baron in @theguardian.com
Cartoon from Ella Baron. First half shows the word 'FACT' in the Hollywood sign font surrounded by wildfire, invoking the LA wildfires. Second half shows Mark Zuckerberg, Elon Musk and Donald Trump holding a large green 'Cheque'.

Former Tory Brexit Secretary joins insane call for UK to leave ECHR.

My latest film explains why joining Russia & Belarus as the only European countries outside the ECHR will do nothing to stop small boats & it will undermine all our rights

Because 2025 = 45² and 45 is a triangle number, we get these lovely sums:

2025 = (1 + 2 + 3 + 4 + 5 + 6 + 7 + 8 + 9)²
2025 = 1³ + 2³ + 3³ + 4³ + 5³ + 6³ + 7³ + 8³ + 9³

Pleasingly the next triangle number 55 is 10 more, so get ready for a repeat of this fact in the year 3025.

I've finished the two views of NGC 1514 today. From JWST is the spectacular infrared view of the planetary nebula's dusty rings. For comparison, the visible light view from PanSTARRS.

More information/processing notes
JWST flic.kr/p/2qA4GF2
PanSTARRS flic.kr/p/2qA4GrZ
A fluffy-textured nebula with two obvious, neutral-colored rings forming a kind of vertically squished figure-8. The rings appear to be in the outer parts of the nebula. The interior of the nebula is a deep red, and looks more concentrated near the center. There is a faint blue haze also present around the central red area. In the very center of the nebula is a light blue colored star. Various small, faint foreground stars and background galaxies also dot the image. A blobby, blue nebula which seems to be made of multiple connected bubbles, kind of like a conglomeration of soap bubbles, but with softly defined, diffuse edges. If you could hold it in your hand, it looks like it would feel like a wispy cotton ball. In the center of the nebula is the brightest star in the image. Fainter, unrelated stars also dot the image randomly.

So I am currently still using Twitter on the grounds that where the far right operate you have to take them on on their own turf. But at @leightonandrews.bsky.social suggestion am also part migrating here. I may need help! I’m not as tech savvy as my Twitter following might suggest!!
