It's Friday, which is as good an excuse as any to remind you about my fantasy subway maps. The Middle Earth Public Transit Authority needs your support! #Tolkien #Subway #Maps #LoTR You can purchase prints and such (w/o the water mark) here: www.etsy.com/shop/Surpris...

Telescopes in the mist.

Yeah, sometimes I just zoom around this for fun. Advanced challenge: locate the brown dwarfs! jades.idies.jhu.edu/goods-s/?ra=...

I wrote THE book about The Design and Engineering of Curiosity: How the Mars Rover Performs Its Job. And because space robot design is conservative, it’s a pretty good resource for both the Perseverance rover and the Dragonfly Titan quadcopter. link.springer.com/book/10.1007...

We can all use a little joy right now.

I was never cool enough to be on a first-name basis with Ani, but listening to "You Had Time," I feel like had this been my intro to her, I would have been. She has my vote now.

Alright, folks. November Rain needs some help in the March Sadness tournament. Only 40 minutes to play! And while you’re add it, Ani DiFranco over Ben Folds. marchxness.com

Also this bookstore in the Tucson airport now has several signed copies of When The Moon Hits Your Eye. Signed by me, to be clear.

Excited to help see this project through!

1/5! Considering the 10x oversubscription and that I've seen more than one first quintile rejections, I am satisfied. So, what will we be doing? We are going to bring JWST/NIRCam coronagraphy into the optical! We tested a flight spare mask and surprise surprise ... it is transparent.

Brutal.

i love this little website youraislopbores.me

Elon Musk has already started plans to launch a million satellites. Yes. A MILLION. This is a colossally bad idea, and it's not too late to make your voice heard. I explain everything: www.scientificamerican.com/article/ramp... 🔭 🧪

The American Astronomical Society has a page with more info and how you can submit comments to the FCC to stop this travesty. Hurry though; submissions end today. aas.org/action-alert...

We're hiring a Research Engineer at the U. Arizona's Imaging Technology Lab (ITL; itl.arizona.edu). If you have hands-on lab experience and are interested in working on cutting-edge tech development for astronomy / scientific sensors, I encourage you to apply! arizona.csod.com/ux/ats/caree...

Follow-up comment on how bad it is on the ground at NASA Goddard Space Flight Center. 🔭

Anonymized chat from a telecon right now on the scale of destruction at NASA Goddard Space Flight Center and how the best news source about it is the volunteer Greenbelt News Review (www.greenbeltnewsreview.com). ☹️ 🔭

What Sarah said.

roses are red cherenkov is blue just use a screwdriver what's the worst it could do

It occurs to me that I never announced my *major* career news on this site. A little over year ago, I took over as Director of the Imaging Technology Lab (ITL; itl.arizona.edu) at U. of Arizona. Founded by Mike Lesser when I was still a nascent proto-astronomer, ITL makes scientific imaging sensors.

Hey y'all. I'm hiring. Are you interested in building instruments for astrophysics? wd5.myworkdaysite.com/recruiting/u...

Interesting paper on requirements for undergraduate astronomy degrees and how non-uniform they are, and how this impacts students with these degrees: arxiv.org/abs/2602.03959

As an astronomer I get asked a lot what kind of telescope 🔭 so-and-so should get for themselves or their [spouse/kid/etc]. I’m clueless. I use BIG telescopes and have never purchased one in my life. But @philplait.bsky.social knows! Thx, Phil! badastronomy.beehiiv.com/p/ban-275-te...

Find a person who will not only buy you a Galaxy-class starship, but get in line early enough to get the limited-edition bonus gifts.

The Florence Project does great work. I highly recommend them for your charitable giving this season. Especially if you’re an AZ resident and are looking for an organization to provide for this year’s Charitable Tax Credit (1:1 tax reduction up to $495/$987 for those filing single/joint this year).

FIRRP does great work, give them your money and support.

Are you an IR detectors nerd, or need to go deep into detector systematics for your #JWST MIRI science? You might be interested in this paper on MIRI's Reset Switch Charge Decay effect (RSCD) by Mike Ressler et al 🔭🧪https://iopscience.iop.org/article/10.1088/1538-3873/ae0afb

i made a template you can use to think about what "frame/negation/kirby" looks like for other issues. For example: Frame: DOGE is a govt efficiency project to save $ Negation: Actually it made things less efficient and cost $ Kirby: DOGE was a project to break and privatize federal bureaucracy

Ahhhh gorgeous! Sample print of Leviathan’s Wake has arrived. Just have to decide on a couple sizes, which is a bit tricky since the original was an awkward size

Somehow I missed that there’s a new Neko Case album out?

I 100% thought this was meant to be an image/drawing of a nautilus or some relative.

A lot to say about this, but one thing is that the Professor in question was a lecturer, and thus did not have tenure. The destruction of academic freedom is inextricably linked to the loss of worker protection in the university.

Highly recommend any opportunity to listen to and hangout with acclaimed authors and all-around wonderful human Manuel Muñoz!

You might have heard of this company that wants to put giant reflectors in space to "light up" parts of the earth. It would be catastrophic not just for astronomers, but for...any people or creatures who thrive at night. Have comments? The American Astronomical Society would love to hear from you.

Inside you are two wolves, five sled dogs, eight Norwegian research scientists, Bennings, Norris, Palmer, Windows, Fuchs, Nauls, Blair, Garry, and Doc Copper.

I really dislike how science has started calling almost any fancy computational technique AI. 🧪 The framing of this entire article makes it sound like a benevolent AI independently made these drugs. That is *pure fantasy*. Instead: a team of scientists made a machine learning model for a study.

Someone commented that I haven’t posted much wildlife lately. Truth is the camera battery died as I’ve been away. Enjoy these javelina being chaotic a week ago.

Very much appreciate the shout-out, Senator. I would also like to note that UofA’s Imaging Technology Laboratory was responsible for manufacturing almost half of the sensors for Rubin’s science camera. astro.arizona.edu/news/tiny-se...

Water boatcrew were one of my favorite aquatic insects to watch zipping around my pond when growing up. These articulated models are so f'ing cool. I want one.
