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.
  • Elliptical. An elliptical galaxy: a smooth swarm of stars on randomly tilted orbits, with almost no cold gas left to build anything new.

Sense of scale

  • 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 15.9 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.

Its true colour

  • Red and dead. Ellipticals glow reddish because every short-lived blue star they ever had has already died. Astronomers call them 'red and dead'.

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 7554

NGC 7554 is a rare galaxy. It sits in the constellation Psc and shines at apparent magnitude 15.89.

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 7554 in the constellation Psc. At apparent magnitude 15.89, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 7554 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 7554 is a rare galaxy

NGC 7554 scores 34 points on Spacedle's rarity scale, which places it in the rare tier. Another 16 points would lift it into a rarer tier.

That score comes from 5 science badges — Galaxy, Elliptical galaxy, On the zodiac, Ghostly low surface brightness 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.
