Trivia

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

  • 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 8.2 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Carina.
  • 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 March — that's when to go looking.

Its true colour

  • Its true colour. Open clusters look blue-white because they are young — their hottest, bluest stars have not had time to die yet.

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.

About NGC 3590

NGC 3590 is a common cluster. It sits in the constellation Car and shines at apparent magnitude 8.2.

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

How to see it

Look for NGC 3590 in the constellation Car. At apparent magnitude 8.2, it is an easy target for binoculars.

Like any astronomical target, NGC 3590 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 NGC 3590 is a common cluster

NGC 3590 scores 20 points on Spacedle's rarity scale, which places it in the common tier. Another 2 points would lift it into a rarer tier.

That score comes from 3 science badges — Star cluster, 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.
