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

  • 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 15 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Eridanus.
  • Southern sky. It rides the southern half of the sky — an easier target the further south you are.
  • Best time of year. It stands highest in the middle of the night around November — that's when to go looking.

Could we get there?

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

About NGC 1203A

NGC 1203A is an uncommon galaxy. It lies about 442,282,846.6 light-years from Earth, sits in the constellation Eri and shines at apparent magnitude 15.01.

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 1203A in the constellation Eri. At apparent magnitude 15.01, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, NGC 1203A 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 1203A is an uncommon galaxy

NGC 1203A scores 27 points on Spacedle's rarity scale, which places it in the uncommon tier. Another 7 points would lift it into a rarer tier.

That score comes from 4 science badges — Galaxy, Outside our galaxy entirely, Elliptical galaxy 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.
