Imagine, if you will, that NASA updated its website to suggest gravity might not exist, prompting CalTech and CERN to release statements saying, "With great sadness, we can no longer recommend listening to NASA."

This is what's happening in epidemiology.

It’s widely known (and, I think, pretty uncontroversial) that learning requires effort — specifically, if you don’t have to work at getting the knowledge, it won’t stick.

Even if an LLM could be trusted to give you correct information 100% of the time, it would be an inferior method of learning it.
Relying on ChatGPT to teach you about a topic leaves you with shallower knowledge than Googling and reading about it, according to new research that compared what more than 10,000 people knew after using one method or the other.

Currently writing a proposal on science misinformation and 3i/ATLAS and hooboy some of those theories are wild. It's only knowing that this has happened so often in history as well that prevents me from thinking we've lost it as a species....

So there's a side conversation about slow fashion and sustainable wages, and I have a lot of thoughts because I went through a period where I was trying to figure out how to get things that would last that were ethically made and also fit me.

My other other conclusion is that "outfit recycling" should be the highest badge of honor in fashion and so we should STOP complimenting people for new clothes and START complimenting people who wear the same thing again.

I was browsing through NASA’s Photojournal archive when I found this historic image of Saturn, taken by Voyager 2 on Aug. 11, 1981.

The spacecraft was about 14.7 million kilometres away when the picture was captured.

In 2022, #Arrakihs was selected as a fast mission under #CosmicVision.

By imaging Milky Way-type galaxies in the nearby Universe, Arrakihs will provide important measurements to address key questions in galaxy formation theory.

3 years ago, NASA crashed the DART spacecraft into an asteroid at 22,000 kilometers per hour. The event changed the asteroid's orbit and tilt & sent it tumbling.

A nearby cubesat captured these remarkable images of the asteroid immediately after the impact. 🧪🔭

I got it... I actually got it... Interstellar comet 3i, imaged from the middle of light-polluted Kendal, at 6am this morning, using my Seestar S50... This comet was already billions of years old before our Sun was even *born*... Very chuffed with this!
