The Event Horizon Telescope has unveiled how Sagittarius A*, the supermassive black hole at the centre of our galaxy, looks like in polarised light, which tells us a lot about the magnetic field around this monster.

The lines overlaid on the image below mark the orientation of the polarisation, from which astronomers can work out the structure of the magnetic field around the black hole.

1/ After having tested it for some time, phanpy.social ( @phanpy ) is now my one and only #Mastodon client. The interface is sleek, and you can tell there's clear intentionality behind every single design choice.

First, look at how gorgeous nested replies look! I no longer struggle trying to decipher who's replying to what. And when you reach too many nested levels, a button gives you the choice to deploy them or not, to keep things clean.

We've just started installing the aluminium cladding that will protect ESO's Extremely Large #Telescope from the harsh conditions of the Atacama Desert in #Chile.

It's amazing to see this project take shape. And it's hard to convey just how big this is –– the dome is 80 m tall!

@thomasfuchs These are real images with the AO on and off, taken with the MUSE instrument at the VLT a few years ago. MUSE gives you a spectrum at every single location within its field of view, so the amount of information that you get is huge. You have more details here: https://www.eso.org/public/news/eso1824/

Do you want to learn about the amazing #engineering behind large optical telescopes? Tom Scott recently visited ESO's Paranal Observatory in #Chile, and in his latest video he tells us all about it, including a sneak peek at our Extremely Large #Telescope !

Look, the Very Large #Telescope has imaged a cosmic #flower! 🌼 The blue "petals" are actually multiple images of the same object, a distant #galaxy seen when the #universe was only 20% of its current age. Light rays from this faraway galaxy were bent by the gravity of a foreground galaxy (the orange one at the centre) creating separate images of the distant source – a so-called Einstein Cross.

I need some #mastdon #help. I know that users can block entire instances. But is it possible (either natively or via third party apps) to:

1. get a list of all the followers of a certain account (all of them, in all instances)

2. mass-mute or mass-block them

I'm asking at the level of individual users, not admins managing their instance.

Thanks!

Folks on #Twitter right now

Me every time I find a tutorial for something I need help with, only to discover it's actually a video and not a text with images:
