Trivia
What it actually is
- What it actually is. A supernova remnant: the shredded corpse of an exploded star, still tearing outwards through interstellar space at thousands of kilometres a second.
Sense of scale
- Sense of scale. Explosions like this forged most of the calcium in your bones and the iron in your blood, then flung it out to be recycled.
Find it in the sky
- Where to look. You'll find it in the constellation Dorado.
- Southern sky only. So far south it never rises for most of the northern hemisphere. To see it you'd have to travel to Chile, South Africa or Australia.
- Best time of year. It stands highest in the middle of the night around December — that's when to go looking.
Its true colour
- Its true colour. Its tangled filaments glow in the colours of shock-heated gas, and it radiates in X-rays and radio as well as light.
How we came to know it
- The New General Catalogue. Its NGC number comes from J. L. E. Dreyer's 1888 catalogue, itself built on decades of sky sweeps by William Herschel and his sister Caroline.

Why NGC 1918 is a rare nebula
NGC 1918 scores 34 points on Spacedle's rarity scale, which places it in the rare tier. Another 16 points would lift it into a rarer tier.
That score comes from 2 science badges — Nebula and Supernova remnant — 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.
