@neonkaaa I'd also disagree with the "panic" characterization. changing social media platforms is pretty low stakes business unless you're running a business on the platform or something like that.
@neonkaaa one reason that I had to have explained to me is his proclamations about so-called "free speech" translates, probably fairly, to harassment in a lot of women's minds on public social media which they might fear wouldn't be handled as well under Musk's leadership. i have no idea how well it's handled now. perhaps it's just about the tone he sets that emboldens trolls on the platform
then, I guess, to some it's just like "here's a change...I don't know what's going to happen, but it's leaning towards more shitty... let's see what else is out there"
On Thursdays I do the space/astronomy news -- this week featuring:
○ Hubble's 32nd anniversary!
○ JWST is allllmost entirely cooled (4 primary mirror segments to go!)
○ all DNA/RNA building blocks have now been found in meteorites
○ good-bye Axiom-1, hello Crew-4!
○ β Pic exocomets are similar to ours
○ Ingenuity investigates landing debris
Please enjoy this awesome video of the HR 8799 system made by Jason Wang, for anyone who hadn't seen it yet.

The star itself was blocked by the telescope so we can see the planets, though some of the light still scatters around the edges. All four known planets are visible. The orbital motion is interpolated from a series of images taken by the Keck Telescope in Hawaii.
As for the planets themselves...
Good evening #Astronomy and #AstroPhotography Mastodon (#Astrodon?)
Here's two pictures of the spiral #galaxy Messier 100, taken by my colleague and myself on the Nordic Optical Telescope in La Palma, Canary Islands, by myself and my colleague Håkon.
The galaxy is very bright in the central region, so it is hard to get the color scaling right and show detail both in the center and outskirts without getting parts saturated or too dark. Here is an attempt in logarithmic scaling and linear scaling. I also tried making one in square-root scaling but that did not turn out so well.
As a little bonus, we managed to catch the galaxy while a supernova was going off. Can you spot it?
@rgegriff I used to have that problem, but I think with a combination of tab-complete only working for the first argument and just using the command a fair bit, it popped into place
@nebunez that makes sense, but @_astronoMay was also making some of these updates between meetings and things, so making several smaller posts may be more convenient
We refer to these measurements in "parts per million", i.e. if we measure one million photons exactly one of them will have been impacted by the planet's atmosphere.
For a hypothetical earth-sized planet around a small star, a biosignature is 10 parts per million
To put into context how hard this is, measuring a biosignature in the atmosphere of this hypothetical #exoplanet is equivalent to finding a SINGLE grain of rice in a 5 lb bag.
@niconiconi happens all the time, but with colleagues. even if I feel the solution coming on though, I still send usually just so I have someone who knows where I'm going in case I fall down a rabbit hole
PSA to newcomers, crossposting
@ashwinvis not sure I agree it's "generally frowned upon". like, I've never seen any mention that the practice itself is bad. it becomes annoying if you are only replying on one site or the other when your posts are conversational in nature, or you're posting @ mentions for Twitter users exclusively, since not all clients can smoothly link to their Twitter profile.
Did you see the news that all of the #JWST instruments are aligned now?
Check out this comparison of one of the newly released calibration images from the MIRI instrument compared to images taken of the same region of space by the WISE and Spitzer space telescopes! Look at that resolution! So many newly resolved stars and structures! 🤩
I can't wait for all the new discoveries we'll make with JWST! #Science data starts in only a couple months!

@gabek that doesn't really make sense though. every piece of software makes some architectural choices that limit how you can use it or offer opportunities. the web is just a platform. I can make web site that's easily read across multiple platforms, scalable, accessible...or not.
@mohammed_alkhwarizmi that's some conspiracy theorist type of math 😆
Environmental impacts of eletric engines materials
@tathibagatini hello. are you suggesting that iron mining is more destructive than platinum mining? or just that it has it's own costs? something else?
