So, How to Build an Astrolabe: Part Two

Plate to represent the Tropics and the Equator

The construction continues into part two!

The middle plate--known as the Tympan--is perhaps the most complex piece of the entire astrolabe, so I am going to be breaking it into a few parts to make it more readable

The first part starts with just three concentric circles for the Tropic of Cancer, Tropic of Capricorn, and the Equator.

No math needed!

This is a step-by-step guide to the complete construction of an astrolabe that I think might exist. At least, in any accessible form.

My goal is for this to be as accessible as possible for any kind of reader, so if there are any question, free free to reach out

🚀 Enjoy! Stay safe and keep learning, fellow chrononauts 🚀

im rly stoked for the spirit city update. its (tragically) been a minute since ive booted it up, but it's so cozy and it's nice to see the devs pour a lot of love into it. telling myself to keep it out daily as a habit again. it's zen and p comforting to have in the bg while you slog through emails tbh.

the destiel crowd needs to understand that cas replaced god (his father) with dean and that this did nothing good for him whatsoever

besides introducing him to sam

if you like this sort of thing i strongly recommend getting Space Engine off steam, loading up the solar system, and watching it all warble around at the same time. everything is very tenuously held together and is by no means permanent and if you're feeling adventurous, trying to make your *own* (relatively) stable system highlights this amazingly well

Cylinder Dial

Sometimes also called a Pillar Dial or a Shepard Dial

This strange looking device is actually a portal sundial! The metal arm is the “gnomon” (the part of the sundial that casts a shadow) and the body is carved with different curved horizontal lines for times and vertical columns for months

This sundial is set for the 37th parallel north (37.3 degrees North latitude) which includes places like the island of Sicily, Greece, as well as places in Syria, Iran, China, and through the center of the United States. This kind of information can make it possible to determine where this device was originally made or at least where it was intended to be used 🔎

Helpfully, it also just so happens it is “inscribed on the dial corresponds with that of Catania in Sicily” so this device was likely made to operate in Sicily

(A very simple) Mystery solved!

What's your decision making process like for thrifting pieces? I've started looking at thrifting more earnestly, and at antiques in particular to add a bit more character to my otherwise midcentury-influenced space, but I always struggle with envisioning if a piece will "go" with everything else. But you seem like you've got the mixing and matching of pieces down pat, do I'd love to hear your thoughts!

I've gotten a bunch of asks in this vein so I'm going to go a little broader than this ask to cover the general topic.

On a purely practical level, you need to know what you have. I keep what I call a house journal, which is a notebook where I've drawn out room layouts, with measurements for available space, lists of what I'm looking for, dimensions for things like doorways (do not buy anything larger than your doorways) and even fabric and paint swatches. I also keep a digital photo album of house pictures, so if I'm trying to see if something will go, I don't have to rely entirely on memory.

So, important note: my background is not in interior design--it's in set design, studio art, and graphic design, so for me, I fall back on narrative. When you're designing interior spaces for theater or film, the room is not primarily functional: it is, first and foremost, an extension of the character that inhabits it. The room exists to tell you about the person in it.

And often, that's the tack I take in my house--not using my home as a framing device for myself, but for imagined characters. For example, my living room is The Adventurer, or the Archaeologist. The character for that room is someone from decent money in the late Victorian period, the sort of person who spent their live traveling for no particular reason, and brought home all manner of oddities. The room is rich in color and texture; the furniture is mostly late 1800s, and it's both formal and lived in. Choosing things for this room, I ask if that character would own that object. I also used unifying wood tones, and a similar depth of color, to tie things in. Pick a color palette and stick to it.

My drawing room is the Alchemist. There are lots of celestial elements, but it's a workroom, so most of the furniture is very practical and simply designed. It's beaten and worn in, showing marks of use. There is lots of storage, and curious little things in jars, and plants and bones and the tools of my trade. The Alchemist uses this space to make impossible things.

The question then is not "does this match" but "would the character that embodies this space choose this? Why? What does it say about them?"

And what all of that tells you about me, is, well....I don't know, really?

Navigating Deep Space by Starlight

On August 6, 1967, astrophysicist Jocelyn Bell Burnell noticed a blip in her radio telescope data. And then another. Eventually, Bell Burnell figured out that these blips, or pulses, were not from people or machines.

The blips were constant. There was something in space that was pulsing in a regular pattern, and Bell Burnell figured out that it was a pulsar: a rapidly spinning neutron star emitting beams of light. Neutron stars are superdense objects created when a massive star dies. Not only are they dense, but neutron stars can also spin really fast! Every star we observe spins, and due to a property called angular momentum, as a collapsing star gets smaller and denser, it spins faster. It’s like how ice skaters spin faster as they bring their arms closer to their bodies and make the space that they take up smaller.

The pulses of light coming from these whirling stars are like the beacons spinning at the tops of lighthouses that help sailors safely approach the shore. As the pulsar spins, beams of radio waves (and other types of light) are swept out into the universe with each turn. The light appears and disappears from our view each time the star rotates.

After decades of studying pulsars, astronomers wondered—could they serve as cosmic beacons to help future space explorers navigate the universe? To see if it could work, scientists needed to do some testing!

First, it was important to gather more data. NASA’s NICER, or Neutron star Interior Composition Explorer, is a telescope that was installed aboard the International Space Station in 2017. Its goal is to find out things about neutron stars like their sizes and densities, using an array of 56 special X-ray concentrators and sensitive detectors to capture and measure pulsars’ light.

But how can we use these X-ray pulses as navigational tools? Enter SEXTANT, or Station Explorer for X-ray Timing and Navigation Technology. If NICER was your phone, SEXTANT would be like an app on it.  

During the first few years of NICER’s observations, SEXTANT created an on-board navigation system using NICER’s pulsar data. It worked by measuring the consistent timing between each pulsar’s pulses to map a set of cosmic beacons.

When calculating position or location, extremely accurate timekeeping is essential. We usually rely on atomic clocks, which use the predictable fluctuations of atoms to tick away the seconds. These atomic clocks can be located on the ground or in space, like the ones on GPS satellites. However, our GPS system only works on or close to Earth, and onboard atomic clocks can be expensive and heavy. Using pulsar observations instead could give us free and reliable “clocks” for navigation. During its experiment, SEXTANT was able to successfully determine the space station’s orbital position!

We can calculate distances using the time taken for a signal to travel between two objects to determine a spacecraft’s approximate location relative to those objects. However, we would need to observe more pulsars to pinpoint a more exact location of a spacecraft. As SEXTANT gathered signals from multiple pulsars, it could more accurately derive its position in space.

So, imagine you are an astronaut on a lengthy journey to the outer solar system. You could use the technology developed by SEXTANT to help plot your course. Since pulsars are reliable and consistent in their spins, you wouldn’t need Wi-Fi or cell service to figure out where you were in relation to your destination. The pulsar-based navigation data could even help you figure out your ETA!

None of these missions or experiments would be possible without Jocelyn Bell Burnell’s keen eye for an odd spot in her radio data decades ago, which set the stage for the idea to use spinning neutron stars as a celestial GPS. Her contribution to the field of astrophysics laid the groundwork for research benefitting the people of the future, who yearn to sail amongst the stars.
