Trivia

Hard to believe

Messier object. One of the 110 showpieces of the Messier list — catalogued as M17.

What it actually is

What it actually is. A nebula: a cloud of interstellar gas and dust, thinner than the best vacuum ever made in a laboratory yet spanning light-years.

Sense of scale

In perspective. Far away by human standards, yet still a local address inside the Milky Way's spiral arms.

Find it in the sky

How to spot it. At magnitude 7 it is just past naked-eye reach — ordinary binoculars will pull it in, over in Sagittarius.
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 June — that's when to go looking.

Could we get there?

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

Getting there

Aboard Voyager 1. ≈ 95.5 million years at Voyager 1's speed (17 km/s).

A nebula: a cloud of interstellar gas and dust, thinner than the best vacuum ever made in a laboratory yet spanning light-years.

How to see it

Look for Omega Nebula in the constellation Sgr. At apparent magnitude 7, it is an easy target for binoculars.

Like any astronomical target, Omega Nebula 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 Omega Nebula is an epic nebula

Omega Nebula scores 72 points on Spacedle's rarity scale, which places it in the epic tier. Another 6 points would lift it into a rarer tier.

That score comes from 10 science badges — Nebula, Distant (over 1,000 light-years), Messier object, Bright deep-sky object, Has a proper name, Diffuse nebula, Toward the galactic centre and On the zodiac — 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.
