Trivia

What makes it special

  • Barred spiral. A barred spiral — a straight bar of stars driving right through the nucleus, feeding gas inwards. Our own Milky Way is one of these.

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.

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 17 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Pisces.
  • Seen from everywhere. It sits almost on the celestial equator, so it can be seen from essentially anywhere on Earth.
  • Best time of year. It stands highest in the middle of the night around September — that's when to go looking.

Could we get there?

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

About NGC 7589

NGC 7589 is a rare galaxy. It lies about 416,119,950.7 light-years from Earth, sits in the constellation Psc and shines at apparent magnitude 17.01.

A barred spiral — a straight bar of stars driving right through the nucleus, feeding gas inwards. Our own Milky Way is one of these.

How to see it

Look for NGC 7589 in the constellation Psc. At apparent magnitude 17.01, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 7589 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 7589 is a rare galaxy

NGC 7589 scores 36 points on Spacedle's rarity scale, which places it in the rare tier. Another 14 points would lift it into a rarer tier.

That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Barred spiral galaxy, On the zodiac and Faint fuzzy (mag > 13) — 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.
