Trivia

What makes it special

It is feeding. Gas spiralling in is squeezed and heated to millions of degrees before it falls, so the disc around it blazes brighter than anything else in the neighbourhood.

Hard to believe

Ultramassive. In the heaviest class of black hole known — a billion Suns or more in a single object.
Mass. It weighs about 66 billion times as much as the Sun, all of it crushed into a region with no surface and no size at all.
Quasar. The disc feeding it outshines every star in its host galaxy put together. Quasars are the brightest steady objects in the known universe, visible clear across the observable cosmos.

Handle with care

A gentle crossing. It is so vast that the stretching is mild at the horizon: you would cross the point of no return entirely intact, feeling nothing, with no way of knowing you had done it.
No way back. Cross the event horizon and every path you could possibly take leads inwards. It is not that you cannot go fast enough — it is that 'out' has stopped being a direction.

What it actually is

Where it lives. It sits at the very heart of TON 618 (host quasar).
What it is. A supermassive black hole. Practically every large galaxy has one, and how they grew so enormous so early in cosmic history is still an open question.

About TON 618

TON 618 is an anomaly black hole. It lies about 1.08×10^10 light-years from Earth and sits in the constellation CVn.

Gas spiralling in is squeezed and heated to millions of degrees before it falls, so the disc around it blazes brighter than anything else in the neighbourhood.

How to see it

Look for TON 618 in the constellation CVn.

Like any astronomical target, TON 618 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 TON 618 is an anomaly black hole

TON 618 scores 92 points on Spacedle's rarity scale, which places it in the anomaly tier. Another 28 points would lift it into a rarer tier.

That score comes from 5 science badges — Black hole, Outside our galaxy entirely, Monster: over a billion Suns, Quasar: outshining its whole galaxy and Seen across cosmic time (z > 1) — 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.
