The constellation of Triangulum, the Triangle // E. Slawik/NOIRLab/NSF/AURA/M. Zamani

Click below to learn more about this constellation and the few named stars here! As always, there's also an annotated image!

Triangulum, which is Latin for "triangle," is one of the original 48 constellations listed by Greek astronomy Ptolemy in the 2nd century. It is named that way because the three brightest stars form a triangle although any three stars will form a triangle, that's just math.

It was known to the Babylonians as "The Plough," and its rising marked the time to begin ploughing the fields in Mesopotamia. To the Ancient Greeks, Triangulum was called "Deltoton," representing an upper-case Greek letter delta Δ. Others associated it with triangular landmarks, such as the Nile delta or the island of Sicily.

In order of brightness, the named stars are:

Alaybasan (β Trianguli), a binary star system about 141 light years from Earth. The system consists of two blue-white giant stars. Its name comes from the Arabic word Al-Aybasān meaning "the two joints."

Mothallah (α Trianguli) is a triple star system about 63 light years away. It consists of a yellow-white giant star and two red dwarf stars. Its name comes from the Arabic phrase raʼs al-muthallath meaning "the head of the triangle."

Apdu (γ Trianguli) is a solitary blue-white giant star about 112 light years from Earth. its name refers to an Ancient Egyptian constellation that was in the same area of the sky, Apdu, the Bird.

Deltoton (δ Trianguli) is a binary star system about 35 light years away. It consists of a yellow Sun-like star and a red dwarf. Its name refers to the original Ancient Greek name for Triangulum, Deltoton.

Triminus (ι Trianguli) is a quadruple star system about 289 light years away. It consists of at least two yellow giants and a yellow-white giant. Its name is an abbreviation of "Tri" for Triangulum and "minus" for Triangulum Minus, an obsolete constellation created by Polish astronomy Johannes Hevelius.

Horna (HAT-P-38) is a solitary Sun-like star about 821 light years away. It has one confirmed exoplanet orbiting it, a Saturn-mass planet, named Hiisi. Both names were given by the people of Finland: Horna is the name of the underworld in Finnish mythology, and Hiisi are evil spirits from Finnish mythology.

Part of me likes how DS2 tried to do something different with the Septentriones and Triangulum. I liked the idea of ​​using stars, but I think the choice of how to adapt them was kind of weak in retrospect. And this design idea, heavily based on the angels from Evangelion, didn't appeal to me at all.

I agree that DS2's scenario was a blast of fresh air. But it's one Atlus probably wouldn't risk these days given they've seemingly moved on from spin-off series and games that are mostly 2D in presentation. It's a shame because the game is still fun, even if the script is a bit repetitive and cliched. The best hope for something similar is if a future SMT were to use an astrological/heavenly bodies theme around planets and their namesake deities (Jupiter/Marduk, Mercury, etc.) and constellations. But this wouldn't leave too much space for the same tired Lucifer/Law conflict that pays the non-Persona bills, so it has little chance of happening. This is why it's such a shame we're losing out on the super low budget spinoffs; what they sometimes lacked in looks, they made up for in creativity.

And I actually kind of like the Star designs, they're appropriately alien, even if they are a bit silly at times.

A lot of these from the Triangulum arc I don't think I've ever seen before. Which tracks, considering I never played it. Oh gosh, I think I have a hankering to watch Evangelion all of a sudden. I haven't watched it since 1999, when a high school friend let me borrow his recording of the entire first series on a single extended play VHS tape (I don't recall how this was possible, but it couldn't have been on more than two tapes). To be fair though, I lived in the anime culture epicenter of Otakon during its nascent days in Baltimore, so my friend could have had connections to the fan sub culture/tape sharing of the time. Perhaps someone out there of similar greying age to me could confirm the plausibility of the legendary single Evangelion EP VHS tape. I had a similar experience watching a low quality EP recording of the DBZ Cell saga. I gotta say, I didn't really appreciate either at the time, but in retrospect it's a pretty cool memory, even for a Japanophile like me who rarely watches anime.

The Triangulum Galaxy

The Triangulum Galaxy is the third largest member of our local cluster of galaxies. At three million light years distance, it is considered nearby on a full cosmic scale.

This neighbouring galaxy is quite different from ours. Note, in the image, several red blemishes. These are large star-forming areas that are different from those in our galaxy.

I photographed the Triangulum Galaxy from my garden in Strasbourg France on two nights: October 6, 2024 and December 27, 2024.

This is an ensemble of 75 images, where each is a three minute exposure (over 3.5 hours of total exposure).

SPACEMAS DAY 3 ✨🪐🌎☄️☀️🌕

The gorgeous spiral galaxy Messier 33 seems to have more than its fair share of glowing hydrogen gas. A prominent member of the local group of galaxies, M33 is also known as the Triangulum Galaxy and lies just 3 million light-years away. The portrait features M33's reddish ionized hydrogen clouds or HII regions. Sprawling along loose spiral arms that wind toward the core, M33's giant HII regions are some of the largest known stellar nurseries, sites of the formation of short-lived but very massive stars. Intense ultraviolet radiation from the luminous, massive stars ionizes the surrounding hydrogen gas and ultimately produces the characteristic red glow. In this image, broadband data were combined with narrowband data recorded through a hydrogen-alpha filter. That filter transmits the light of the strongest visible hydrogen emission line.
