The construction of ESO's Extremely Large keeps progressing! We've started a new series of video updates, and in this first episode we show you how the gigantic steel frame of the dome is taking shape.

Just saw on someone on using to answer a user's question — they didn't disclose it but it was painfully obvious.

Very on-brand, as a large portion of Reddit's user base consists of people who are confidently wrong about everything.

Still, I miss the times before , when being wrong at least required some effort.

sml,

@astro_jcm @dpscifi Fast forward ten years: humanity has abandoned grammar and correct spelling because it turns out that AI just can't fake bad grammar and spelling as well as humans can.

But jokes aside, I don't really have an idea either. Resorting to people's conscience? Enforcing account bans if someone gets caught?
Mandatory labeling would probably be the easiest way for now, as long as we can detect it somewhat accurately.

dpscifi,

@sml @astro_jcm we already have enforceable copyright laws. You can't post text that is copyrighted. You can get sued. The same should be legally true for AI text or images. If you DON'T mark them as AI generated, you should risk being sued or thrown off a social media platform.

Whenever you think that something spat out by or another makes sense, remember that you are the one making sense out of it and not the LLM itself.

In case you missed it, ESO's Very Large in just turned 25! To celebrate this, the first episode of our new hosted show Chasing Starlight recaps some of the coolest science done with this facility.

For the umpteenth time since I've lived in I was almost ran over by a biker who thought chatting side-by-side with his biking buddy justified invading the sidewalk. And when it's not that, it's bikers overtaking other bikers on their right, or just not bothering to use the correct bike-lane to the other side or the street in those areas where they're one-way.

Happy to those who celebrate! Pro tip: never install Genuine People Personality software in a . We did that at Paranal Observatory in and, well, bad idea.

Many people imagine professional astronomers hunched over a and taking notes. We no longer work that way, as light captured by the telescope is registered by complex instruments. But sometimes it's fun to use your eyes!

I took this pic a few years ago, when we removed one of the instruments of ESO's Very Large Telescope in . A screen was temporarily attached in its place, and we used it to project the and show it to everyone at the observatory

@eduardobragaxz @astro_jcm i, as you had the same question

@dannotdaniel @eduardobragaxz @astro_jcm I would guess there are filters removing the shorter (bluer) wavelengths, which are more readily scattered and degrade the image of distant objects.

As a teenager I used to read about the construction of ESO's Very Large , not knowing I would end up working there. Still rocking at 25! The VLT, not me; I'm 40 and my back hurts.

This morning I visited the wonderful Alte Pinakothek in for the umpteenth time, and I just can't have enough of one of my favourite pictures there by Max Liebermann. Whenever I'm at a I can't help but see the similarities with this lively XIX century scene, with and bringing together people of all walks of life.

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:

kkarhan,

@astro_jcm nodds in agreement

What's with the lack of writeups?
People may need to check things on shitty mobile networks...

rlonstein,

@losttourist @astro_jcm

If I come across one of those youtube videos I download just the subtitles (--write-auto-sub --sub-lang en --skip-download) and skim them to decide if watching is worth my time.

Usually it isn't.

I adore , but there's a stark contrast between the open and customizable nature of the platform and the sense of entitlement and ownership I see in certain users towards newcomers.

Telling newcomers that the issues they're assuring you they have aren't real, or claiming that <insert possible new feature> will destroy Mastodon even though you can't back it up with actual data, is a terrible communication strategy.

Build a fence or don't build one, but make up your mind.

@Jonathanglick Exactly! This is an excellent point. There's a strong selection effect here.

You're gonna want to check out this image at full screen, trust me.

Using ESO's VISTA telescope in Chile, astronomers have produced a huge infrared atlas of 5 nearby star-forming regions, revealing details hidden by dust.

Happy ! Here's a pic I took a few years ago at ESO's Paranal Observatory. No planets were harmed 😉

These lasers excite sodium atoms 80-90 km above the ground, creating artificial "stars" that we use to correct atmospheric blur and get sharp images.

I was lucky to get this image chosen as highly commended in the 2020 edition of the Insight Photographer of the Year competition 😊
