The world’s largest and oldest iceberg A23a has finally come to a standstill ✋

It appears to have run aground on the sea bed near the sub-Antarctic Island of South Georgia.

Here's an illustration of its position over the last few days by @magic.bas.ac.uk ⬇️

Before any plants were taller than three feet, and before any animal with a backbone had made it out of the water, the earth was dotted with two-story-tall, silo-like fungi.

They shape the world—and offer lessons for how to live in it.

🌙✨ A Night with the Moon ✨🌙

We're chasing the Moon all week for National Astronomy Week, but let's give it some special attention tonight. It's lit from the side, which creates wonderful shadows in its craters.

To me the cool thing about this image is that the sprinkling of blue stars are in the foreground, some 5 million light years away, while all those gorgeous colorful swirly galaxies are almost unimaginably more distant, out in the far depths of the cosmos. More info: www.stsci.edu/contents/med...
Oh come ON now. This new JWST image is just ASTOUNDING.

I feel like I’m falling looking into it, and that I would fall forever, and that I would enjoy it.

I honestly believe all LLM results should come with a disclaimer reminding people that the thing doesn’t (and absolutely cannot) know any facts or do any reasoning; it is simply designed to *sound* like it knows facts and frequently sweeps some up accidentally in the process.
I really think many if not most of the LLM fail cases are people trying to use it as a search engine. It is the opposite of a search engine.

It's a little chilly out there 🥶 ❄️... so how about a good ol' galaxy smash-up to generate a bit of heat? 🥵

A team of researchers led by the University of Hertfordshire have observed in unprecedented detail a massive collision of galaxies – sparked by one travelling at 2 million mph! 💥
