Trivia

Hard to believe

Messier object. One of the 110 showpieces of the Messier list — catalogued as M29.

What it actually is

What it actually is. An open cluster: a few hundred stars born together out of one collapsing cloud, still drifting along in loose formation.

Sense of scale

In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.
Sense of scale. Gravity is not strong enough to hold it. Within a few hundred million years these siblings will be scattered right around the galaxy.

Find it in the sky

How to spot it. At magnitude 6.6 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Cygnus.
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 July — that's when to go looking.

Could we get there?

Verdict. Impossible with our current technology — and the next millennium of it.

Why NGC 6913 is a rare cluster

NGC 6913 scores 44 points on Spacedle's rarity scale, which places it in the rare tier. Another 6 points would lift it into a rarer tier.

That score comes from 6 science badges — Star cluster, Distant (over 1,000 light-years), Messier object, Bright deep-sky object, Open cluster 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.
