I mean, it *can* be an emergency!

@npub1qsl…t3ey Probably much further down the line, super proud of having typed "draw a cat" and seeing a drawing of a cat or something, dunno :D

Something I like about phanpy.social is that links to toots are displayed as quoted toots, vastly improving the reading experience. Now they've simplified the process with a quote button that adds the link for you. Not the same as having quotes available natively in #Mastodon, but it does help!

Your periodic reminder that Stellarium is an amazing planetarium tool. Free, #OpenSource and very easy to use. There are desktop apps, mobile apps and a web version.

I'm tired of sitting through #science talks where all plots are properly credited but artist's impressions and photographs aren't.
As a researcher and astrophotographer who works with super talented artists, this attitude really bothers me.
You study galaxies at the dawn of time. You look for biomarkers in the atmospheres of distant planets. You can most definitely find who made that cool image you just pasted in your slides.
To those who do credit #art : you're awesome 🤗

The job of a telescope operator has certainly changed quite a bit in the last few centuries 😅
I showed this slide in a talk I gave a few days ago about how and why we're building increasingly larger telescopes. This telescope was built by Johannes Hevelius in the XVII century. Its aperture was only a few cm wide, but its focal length was a whopping 46 m.

This image is made of almost impossible events.
It shows the distribution of hydrogen in M101, a nearby spiral #galaxy. More precisely, we see the radiation emitted by hydrogen atoms during something called hyperfine transition.
The odds of this happening are very rare: on average, you'd have to stare at a hydrogen atom for 10 million years to see this transition. But there's LOTS of hydrogen atoms out there!

@npub1p2e…dfm9 That's new physics right there!

Fun #physics fact for #Caturday
#Cats exist in a quantum superposition of two states: "pet me" and "how dare you touch me you hairless ape". It is only by touching them that their wave function collapses to one of these states.

@npub1z0t…wj4p @npub1rls…7sp6 The stellar density in these clusters is indeed higher than in the solar neighbourhood. Given the mass and radius that I could find for this cluster, the average density would be of the order of a few stars per cubic lightyear. In comparison, the closest star to the Sun is 4 lightyears away.

I know y'all loved the latest #photo I posted of our Extremely Large #Telescope in #Chile. So here's a video showing new footage, including some truly jaw-dropping #drone shots that will make you feel like a bird!
