This black hole has one bright jet and one that’s too faint to see. The reason is relativity and the weird things that happen near the speed of light 🧪🔭 three-alpha.space/p/a-black-ho...
A black hole with just one bright jet
Thanks to relativity we can't see the other one.

3. ⁠this is not the moment for an incredibly expensive increase in state surveillance infrastructure to be run for profit by private tech firms just before Labour ushers in an (even more) authoritarian right wing government.

There were recently new images of two similar sounding but very different objects, the Butterfly Star and the Butterfly Nebula. I explain the difference 🧪🔭 three-alpha.space/p/butterflie...
Butterflies in space
Two very different objects that sound remarkably similar. So what's the difference?

History is full of powerful dictators, all remembered as villains. Hitler, Stalin, Napoleon, Caesar. Imagine what would have to be wrong with you to want to add yourself to that list

Yes, that was the Parkes radio telescope in Australia I think

The detectors are also more sensitive in certain directions, so this is important if you're interested in looking at where in space gravitational waves come from. It's less likely to find things that are in the wrong direction at the times it's more likely to be running. 🧪🔭

Love this. LIGO is more likely to detect gravitational waves at night and during weekends. It's also less likely to detect things on Tuesdays. All because the detectors are more likely to be running at certain times/days. 🔭🧪 arxiv.org/abs/2509.11849
Can LIGO Detect Daylight Savings Time?
Yes, it can. Catalogs produced by networks of Gravitational-wave interferometers are subject to complicated selection effects, and the gold-standard remains direct measurements of the detection prob...

A DMCA takedown notice to their hosting provider would probably work. If you google it you should be able to find a template that you can modify and email. As far as I can tell, their host seems to be hostinger.com

A 36 billion solar mass black hole was recently discovered. That’s hard to imagine, so I’ve worked out how wide it would be compared to the Solar System. It’s, um, rather large 🧪🔭 three-alpha.space/p/the-bigges...
The biggest black hole ever discovered
But just how big is it, exactly?

Fascinating. And also “skulls of the young” is a good name for a metal band.

Pretty sure this "vulnerability" in python-future is nonsense. Supposedly vulnerable because it imports "test" and an attacker could create a file named "test.py" in sys.path. But if the attacker can do that they could spoof literally any imported module github.com/advisories/G...

We learned last month that Betelgeuse probably has a small, hard to see companion. But how do stars end up in binaries, anyway? The answer is all in how stars form in the first place 🔭🧪 three-alpha.space/p/a-companio...
A companion on Orion's shoulder?
The red giant Betelgeuse might have a tiny companion, but how did it get there?

The rest of the output is fine, so it’s doing OK at regurgitating facts, but not so good at analysing specially what it was given

An exoplanet is similar to an eclipsing binary, I mean, not similar to the pulsator.
