You can get my books for the space themed folks (deeply affectionate) in your life! Or maybe you are the space themed folk, in which case you can get them for yourself.

Milky Way: footnote jokes, 45 pgs of citations & silly line drawings.

40 Ways: beautiful diagrams on every page. 🧪🔭📚
A hardback copy of The Milky Way Smells of Rum and Raspberries, by Dr Jillian Scudder. The cover is a deep blue, and has a raspberry galaxy swirled into a martini glass. A hardback copy of 40 Ways to Know A Star, in tan with gold foil on the title. The cover art is an irregular galaxy overlaid with a spherical grid.

#ArtAdventCalendar, from 2022. This one took a while to render and I’m still proud of it. 🐡

In honor of #ArtAdventCalendar, some old (2020) art I still enjoy. 🐡
An illustration of a comet over Stonehenge in flat colors against a gradient sky. The comet has a bright nucleus and the tail is stylized as a set of golden straight lines.

Also seen at OSU: a remarkably comprehensive aversion to the letter M.
A brick building with a fancy relief plaque reading “McPherson Chemical Laboratory”. Both of the letter M are crossed out with red tape.

Today I am at OSU’s Center for Cosmology and AstroParticle Physics
giving a free public lecture tonight, and tomorrow a quick science chat plus a scicomm lecture tomorrow.

I have brought books to sell, and am excited to get to tell people silly space stories. 🔭📚

I’m four feet and five skeins deep into this absurdly cabled project and officially halfway. 🧶
An oblique look at a gray scarf with four different cable patterns in it. A tape measure next to the body of the scarf reads 48 in (4ft) at the working edge.

I need you all to know about the long eared owl, which I learned about last night, and brings the biggest "cat with its ears back" energy to owlhood I've encountered to date 🦉

This weekend also marks my transition into being able to (tax law compliantly) sell copies of my books directly, at in person events!

My desire to head to sci-fi/fantasy cons with a giant sign reading “GET YOUR SPACE FACTS HERE” is increasing.

From spaceweather.com:

From me: booooooooooooo

Screen grab reading: “THE THIRD CME HAS ARRIVED (UPDATED): The highly-anticipated 3rd CME has arrived. It struck Earth's magnetic field at approximately 1917 UTC on Nov. 12th. Our first impression of the impact: It was not strong enough to cause a repeat of last night's extreme aurora display. We are downgrading our storm forecast from category G4 (severe) to G2/G3 (moderate/strong). Aurora alerts: SMS Text.”

Quick reminder, especially to men:

don’t do this!
Snippet of an email which reads, “Your quick wit and retorts to [redacted name]’s odd questions and your "alluring" voice were not what one expects from an astrophysicist. Very impressive! As a retired environmental scientist I…”

That moment when you find ✨Aesthetic✨™️ art at an art festival and the only question is which wall is it going on. 🐈‍⬛

Artist: borksbotanicalcreations.com
A block print in black ink on eggshell paper of a blob shaped cat about to knock over a vase with roses, sitting on a pile of books, with potions on either side and a mug of tea. One of the books reads “book of meowgic”. It is signed and marked 40/250.

Teacup the cat has not minded the extra company.

I am in week 2 of recovery from a long awaited surgery (I am healing well) (it will be at least a month more before I’m fully recovered) (I am on medical leave, my email is being ignored).

Please appreciate my hard working cat as a timeline pause.
A mostly gray cat with white paw tips and back leg stretched out along the bottom of the image is extremely lazily partially curled on her side. Her belly is visible and she looks very relaxed on a pale blue blanket.

Fascinating choice to put this fact in the 8th paragraph
Screenshot of quote posted article reading: “Supervisors working from "a shower" "We won't be able to provide private sessions," says one licensed clinical social worker, who asked to be identified by a middle initial, L., for fear of retaliation. Guaranteed privacy between patient and doctor is a fundamental tenet of quality mental health care, protected by federal law.” The last sentence has been highlighted.

Do you think we get to unlock a new emotion if we hit zero
CNN market tracker dial, with dial reading nearly fully to the left end, reading number 4. Text next to the dial says “Extreme Fear is driving the US market”. The “Extreme Fear” is in bold and deep red.

Apparently CNN has invented this Fear & Greed Index and there’s something very bizarre about a 100 point anxiety to avarice scale

Normal one continues, in any case
Fear and greed index by CNN, showing a dial reading “extreme fear” “fear” “neutral” “greed” “extreme greed”. Current reading is a 9/100 “extreme fear”. Previous close reads 17, a week ago reads 28 (fear), a month ago 12 (extreme fear) and 1 year ago 69 “greed”.
