Trivia

What it actually is

  • What it actually is. A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.
  • Irregular. An irregular galaxy — no disc, no bulge, no symmetry. Most have been pulled out of shape by a larger neighbour's gravity.

Sense of scale

  • In perspective. Deep in the extragalactic distance — further than the entire Virgo Cluster of galaxies.
  • 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

  • How to spot it. At magnitude 12.6 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Octans.
  • 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 June — that's when to go looking.

Could we get there?

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

About NGC 6438A

NGC 6438A is an uncommon galaxy. It lies about 106,732,881.6 light-years from Earth, sits in the constellation Oct and shines at apparent magnitude 12.58.

A galaxy: a gravitationally bound city of stars, gas and dark matter, turning so slowly that a single rotation takes hundreds of millions of years.

How to see it

Look for NGC 6438A in the constellation Oct. At apparent magnitude 12.58, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 6438A 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 6438A is an uncommon galaxy

NGC 6438A scores 32 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 2 points would lift it into a rarer tier.

That score comes from 3 science badges — Galaxy, Outside our galaxy entirely and Irregular galaxy (no shape at all) — 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.
