Taking a break from the afternoon break to bring you some of the most exciting new #science results from the #Exo4 #Exoplanets conference! I'll tell you why I'm excited about these in a thread!
⬇️⬇️⬇️⬇️⬇️
(1) A detection of a proto-planet in the TW Hya Disk. It's currently somewhere around the size of Neptune, but still growing!
(2) 30 new Hot Jupiters from TESS! (Transiting Exoplanet Survey Satellite)
(3) a sub-Earth planet around Proxima Centauri, our nearest neighbor! @asmasca
kind of a wild idea, but if it works, it works. I'm curious how the launch affects payload packaging or if you have to change how your payload is designed at a deeper level.
also would like to know how big they can go https://www.businesswire.com/news/home/20220406005185/en/SpinLaunch-and-NASA-Sign-Space-Act-Agreement-to-Test-Innovative-Mass-Accelerator-Launch-System

Yay! My edits are done for my Bridges art!

I hadn't known who had first determined that hydrogen was the main part of the stars, but apparently it was Gaposchkin. Pretty cool.

@readsteven beautiful orange on the breast. around here the closest I see is the robin. plenty of beautiful briefs of all colors though (cardinals, blue jays, grackles...)
I just searched for more images of these Orioles though: seems like oranges are really the thing since every third photo has an orange or some kind of citrus in frame
@neonkaaa I don't know what you're shortening. the point is that a lot of "free speech" rhetoric regarding social media is not really about free speech, but it's about certain people wanting a megaphone for whatever they want to say, without negative consequences, even when what they say arguably violates the terms of service on the platform. maybe it's beating a dead horse to say, but Twitter isn't a state organ and has no power to restrict your speech--it's a service you can use for purposes that Twitter and it's officers/employees allow, but (as has very obviously happened) folks who don't like the restrictions of the service can go elsewhere and still say whatever they want within the bounds of the law.
With regard to Musk himself, people tend to point to him baselessly accusing that one diver of being a pedophile. There's also the criticism of working conditions and how harassment has been handled at his other company Tesla. There's other stuff that I won't bring up because I'm even less familiar with the facts of the matter...
@ephemeral merveilles.town, maybe?
@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
