Trivia
What it actually is
- What it actually is. A star cluster still wrapped in the nebula that made it — newborn stars lighting up their own birth cloud.
Find it in the sky
- Where to look. You'll find it in the constellation Cassiopeia.
- 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. The stars are blue-white and brand new; the gas around them glows red, ionised by their ultraviolet glare.
How we came to know it
- The Index Catalogue. The IC was the 1895 and 1908 supplement to the NGC — the first catalogue in history to be filled largely with objects found on photographic plates rather than by eye.

Why IC 1590 is an uncommon cluster
IC 1590 scores 33 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 1 point would lift it into a rarer tier.
That score comes from 4 science badges — Star cluster, Cluster still wrapped in its gas, Never sets (northern circumpolar) and Coming towards us — 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.
