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 12.8 it is far too faint for the eye: this one belongs to cameras and long exposures, over in Ursa Major.
  • Northern sky. It rides the northern half of the sky — an easier target the further north you are.
  • Best time of year. It stands highest in the middle of the night around March — that's when to go looking.

Could we get there?

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

About Medusa Galaxy Merger

Medusa Galaxy Merger is a rare galaxy. It lies about 114,261,873 light-years from Earth, sits in the constellation UMa and shines at apparent magnitude 12.77.

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 Medusa Galaxy Merger in the constellation UMa. At apparent magnitude 12.77, it takes a larger telescope or a long-exposure image to capture.

Like any astronomical target, Medusa Galaxy Merger 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 Medusa Galaxy Merger is a rare galaxy

Medusa Galaxy Merger scores 42 points on Spacedle's rarity scale, which places it in the rare tier. Another 8 points would lift it into a rarer tier.

That score comes from 5 science badges — Galaxy, Outside our galaxy entirely, Has a proper name, Barred spiral galaxy and Never sets (northern circumpolar) — 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.
