This is amazing work, especially in dealing with the systematics. Definitely something I'll be looking at from now on.

I heartily approve of your gif usage.

Oh. my. god. I'd never realised that they were to the minute too, but of course that makes complete sense - thank you!
Absolutely amazing that it landed on that paper bag, too
I am so sorry for your loss Michele. Sterkte.
Every place has its own time using local noon. Bonus: this was done for railway stations in Victorian era England, and resulted in town clocks having two different hands - one for London time, and another for local time!
I'm getting a migraine just looking at this

New NICER neutron star results this morning, led by Yves Kini! For the first rotation-powered millisecond pulsar we ever reported on, PSR J0030+0451.
More data (6 years!), background constraints fully incorporated, and improved sampling. #highenergyastro ππ§ͺ

The answer is "No, go do something else instead"
I really love the new YouTube βyouβre not a botβ sign in page, because when I click to watch a video this dialog pops up and I ask myself βDo I really need to watch this video?β and the answer is almost always βNo I donβtβ and I go do something more productive/useful instead. #lifehack
Huh. Weird. My Visles keyboard and/or Mac OSX decided to spontaneously swap the Option and Command keys on me. This led to a few puzzling minutes wondering if my keyboard had brokenβ¦
Beautiful work! I really love the paper calculators that were produced before mechanical computers. The number of nomograms produced was also amazing.
Since yesterday, the Einstein AI cheatbot website underwent some rebranding. The tagline changed from "Einstein does the busywork so you don't have to," to "Einstein is the personal tutor every student deserves." In the FAQ, "How does Einstein do all this?" became "How does Einstein help me learn?"
The FCC just opened public comments on SpaceX's plan to launch a million satellites to do AI compute in space. Under the current proposal, an environmental review won't be required. Please consider submitting a public comment to oppose this damaging plan.

This paper gets into the ballpark but not the ludicrous numbers discussed above.
Reflect Orbital particularly concerns me given its many large satellites with (at a particular angle) a surface brightness comparable to the Sun.

That. Is. MAGNIFICENT!
We tried to get the word "rainbows" printed in rainbow colours in MNRAS. We got a very curt "please do not do that" in response from the copy editor.

Itβs taken me a couple of days to work out where Iβve seen that look before, then as I was watching βThe Exorcistβ the answer came to me in a flashβ¦.
I've tried for a few conferences to get below 50 words on a poster. I'm getting close....
I was in a swimming club and regularly came in dead last. I didn't mind because I loved swimming! One time I beat one other "golden" student and they had a full blown melt down in the pool next to me.
Because I beat them. Just the once.
That indicent put me off student sports for good.
Almost all primary journals are digital only - there are no hardcopy prints of the publications. It is hard to imagine how it is justified to charge thousands of USD for a single article. Especially when considering that current peer-review journals would not exist without the main ingredient: free reviewers.
Also, this is maddening.
The authors could have *asked* why even zero-profit-margin journals is the AAS Journals cost so much to produce. No need to imagine! There's a lot more to producing a real, archived, edited, typeset, scientific article with data than peer reviewer labor.
Every time I see people complain about doing peer review βfor freeβ for community journals I lose my mind further. If youβre a salaried academic this is your job! The money would come from the community anyway in these journals! In every industry people fought to convert piecework to wage or salary!
And before anyone gets mad in the replies - I said community journals! Elsevier journals can go jump in the lake, etc. But weβre lucky in astronomy that ApJ/PASA/MNRAS/A&A are the main venues anyway and we donβt have a plague of the parasite journals. We need to support them and keep it that way!
And before, etc - love OJA and letβs keep that going
Always nice to see our group's discoveries make the rounds :) kenworthy.space/projects/yses/
Hello HARPS3! Are you ready for some optics? OK then ... let the optical installation begin!β
LLMs do not understand, will not understand, and cannot ever understand information. It's a glorified search engine combined with auto-compete, and you should treat it as such. No matter how much LLM companies try to tell you their machines can think or reason, they cannot and will not.

Two images of a point source representing the transient event. The first image is circular, the second one is not circular, suggesting it may be quite close to the Earth.
βDonβt blink. Donβt even blinkβ: Arima+ on βAn optical transient candidate of β² 2-second duration captured by wide-field video observationsβ where they look up into the Earthβs shadow to capture these very fleeting events. Iβm not sure of their interpretation, but itβs fascinating. #astrodon β
Threads was an initially inconspicuous made for TV film about nuclear war's impact on real people. The film plays out in excruciating, accurate detail how awful it would be for every single human affected. It is the best illustration of the horrors and human cost of nuclear war that I am aware of.
