I’m an artist and planetarian. I pretend it’s night all day long, talk a lot, and teach people about space.

Departure from planets. We’re doing laser nutcracker in the dome this year. It’s all my fault. The Tchaikovsky is already making me crazier.

Of course I needed to be able to race along Saturn’s rings in my planetarium. Obviously. Duh.

Okay. In response to a bizarre phone call we got today, if “the devil keeps getting into your house at night” please… don’t call the planetarium for help. We can’t help. We just have. Like. Stars. And planets. #museum #scienceeducation #planetarium

After trying to identify surface features on a 3D model of asteroid Bennu using a 2D map, I am of the personal opinion that we really should have punched Bennu much harder. #spaceexploration #osirisrex #osirisapex #bennu #scienceillustration
A cartoon image of the Osiris Rex spacecraft and asteroid bennu. Bennu has a goofy expression. Osiris Rex has a long arm extended. Text reads: “OSIRIS-REx: that time NASA decided to punch an asteroid right in its stupid face. For science!”

Haven’t done as much space art recently because I have been focusing my efforts on laser shows!! Laser Nutcracker is a work in progress, because I am full of hubris and holiday spirit. Or something. #planetarium
A glowing laser image of a classic holiday nutcracker in a simple cartoon style. The laser lines are red, white, and blue.

Don’t think about it too hard. I live in a planetarium at the beach.
A black and white drawing of Saturn over a breaking wave, inscribed in an elongated hexagon. Text overlays the image which reads “from the sea to the sky”

Venera 13 probably lasted longer than 127 minutes, but not by that much. It did stop phoning home a bit past the two hour mark though.
Cartoon drawing of the Venera 13 Venus lander. It looks like a ball sitting on top of a washer with another washer and a soda cap on top. A thermal exhaust chimney comes out of the ball and extends upward through the top washer.

Another possible postcard design?
A cartoon illustration of a cherubic alien child looking at a comet. The child has large goblin ears and freckles. The comet has a smiling face and a long arching tail.

Working on a possible postcard design.
Two purple goblin women look happily at a cartoon moon in a vivid rainbow nebula. They are warmly lit from below. One of the women is pointing at the moon.

Read a paper about how early Venus might’ve been super nice actually and now I am sad I can’t visit. ☹️

A cartoon illustration of many dwarf planets and their moons, not to scale. They’re colored in and labeled with their names. Clockwise from the top right: Makemake and Mk2, Ceres, Haumea with Hi’iaka and Namaka, Eris and Dysnomia, Quaoar and Weywot, Pluto and Charon, and Eris. Text in the middle reads “Lots of small worlds after all!”

Alas, poor George. (Kidding. I’m American. We fought a revolution against King George.) #uranus #solarsystem #planets
A watercolor illustration of the planet Uranus with its two largest moons. A crossed out word at the top reads “George”. Underneath is written “Uranus.” A speech bubble coming from a grumpy cartoon face on the planet reads “I was originally called George.”

How to know when the book you’re reading is NOT by someone with actual astronomy knowledge: “It’s about a hundred AU to the galactic rim.”

As a side effect of being a mostly self taught goblin, it occurs to me that I can name and identify more features on Charon than on Earth’s moon…

Huh. We seem to have lost a school group. Maybe to the Bermuda Triangle? We got a call, but the audio was breaking up and the bus was having trouble….

Sometimes, the headlines just write themselves!
Image of the planet Uranus, shared in a humorous science post by IFLScience. The caption reads: "Uranus May Be Filled With A Lot More Methane Than We Thought.

Hey, science educators! Do you tire of telling people which end of the telescope is the right end? Give them this!! #science #astronomy #telescope #starparty #scienceeducation #informaleducation
A basic instruction sheet for telescopes. It says which end of the telescope you can see through and the very basics of how telescopes work.

It’s summer, so we have our more popular laser shows pulled to attract the crowds. #scienceillustration #planetarium #lyrics
A watercolor illustration of Saturn over the moon. A retro font reads “Love you to the moon and to Saturn”.

Stuck in the dark and the dome. Shame I can’t enjoy the weather today. Coincidentally, have an illustration of Andromeda: a princess who didn’t ask for her crazy elders to do any of the nonsense that put her & her country in danger. #andromeda #illustration #nokings
An illustration of the Andromeda constellation with the constellation name in gold at the bottom. The constellation depicts a beautiful African princess with natural hair and an angry expression. She has broken chains around her wrist, used in the myth to chain her to a rock to placate the monster that threatened her country.

I’m glad people enjoy the planetarium shows enough that they don’t want to leave at the end. However, to show my appreciation and prepare for the next show, I will be blasting infomercial music after the end song is over.

Hmmm. To use this as a coloring page or not?

We have themed mazes and coloring pages in our lobby, but I didn’t see any themed for the Vera Rubin observatory…problem solved. #maze #activitysheet #veracrubinobservatory #verarubinobservatory
