Trivia

Hard to believe

  • Messier object. One of the 110 showpieces of the Messier list — catalogued as M33.

What it actually is

  • What it actually is. A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.
  • Spiral. A spiral galaxy. Those arms are not solid structures but traffic jams — density waves that stars drift into and out of as they orbit.

Sense of scale

  • Scale. Home to hundreds of billions of stars — a universe unto itself, and every one of those points of light could have planets.

Find it in the sky

  • How to spot it. At magnitude 5.8 you can see it with your own eyes from a dark site, over in Triangulum.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around October — that's when to go looking.

Its true colour

  • Its true colour. Its colour is a census: blue where gas is still collapsing into hot young stars, yellow-red in the old, settled core.

About Triangulum Galaxy

Triangulum Galaxy is an anomaly galaxy. It sits in the constellation Tri and shines at apparent magnitude 5.79.

A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.

How to see it

Look for Triangulum Galaxy in the constellation Tri. At apparent magnitude 5.79, it can be glimpsed with the unaided eye under dark skies.

Like any astronomical target, Triangulum Galaxy is best seen from a dark site away from city lights, and when it is above the horizon depends on your latitude and the time of year. The visibility panel above works out tonight's viewing window for your saved location.

Why Triangulum Galaxy is an anomaly galaxy

Triangulum Galaxy scores 91 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 29 points would lift it into a rarer tier.

That score comes from 8 science badges — Galaxy, Messier object, Bright deep-sky object, Has a proper name, Spiral galaxy, Bigger on the sky than the full Moon, Coming towards us and The Triangulum Galaxy — each earned for a real, measurable property of the object. Rarity on Spacedle is never random: the more remarkable an object's astrophysics, the more badges it collects, the higher it scores, and the rarer it ranks.
