Trivia
What it actually is
- What it actually is. Not one galaxy but two, locked in a gravitational embrace. Encounters like this shred spiral arms and trigger furious bursts of star formation.
Sense of scale
- Sense of scale. Galaxies pass through each other almost without collisions — the stars are so far apart that they simply miss.
- 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
- Where to look. You'll find it in the constellation Pavo.
- 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 July — that's when to go looking.
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 4759 is an uncommon galaxy
IC 4759 scores 28 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 6 points would lift it into a rarer tier.
That score comes from 2 science badges — Galaxy and Interacting galaxy pair — 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.
