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.

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 NGC 4395.
What it is. An intermediate-mass black hole — the long-missing link between the star-sized ones and the giants at galactic centres. Only a handful are known anywhere.

Sense of scale

In perspective. Further than Andromeda, the most distant thing the unaided human eye can see.
Its event horizon. The point of no return sits 29.5 thousand km out, making the horizon about 59.1 thousand km across.
Sense of scale. Its event horizon is wider than the Earth.

About NGC 4395

NGC 4395 is an epic black hole. It lies about 14,000,000 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 NGC 4395 in the constellation CVn.

Like any astronomical target, NGC 4395 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 4395 is an epic black hole

NGC 4395 scores 60 points on Spacedle's rarity scale, which places it in the epic tier. Another 18 points would lift it into a rarer tier.

That score comes from 4 science badges — Black hole, Outside our galaxy entirely, Intermediate-mass black hole (the missing link) and Actively feeding — 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.
