To the middle of the Milky Way

Galactic Compass presents you with a floating arrow with one purpose: to point the direction of the central supermassive black hole of the Milky Way galaxy, known as Sagittarius A*.

The middle of the galaxy is 26,000 light years.. but which way?

The direction depends on:

- the time of day
- your location
- the position of the Earth in its orbit

It's hard to figure out in your head.

Well now the answer is in your pocket. If you're ever lost, Galactic Compass can show you the way.

What’s New

Version 1.4

New feature! Enable the compass background to see the horizon and also the ecliptic – the edge-on position of our Solar System.

Also, in the new Debug screen... want to know when "galaxyrise" and "galaxyset" are today? Now there's a chart for that! (Yes I just made up those words.)

Q-Tim ,

Makes you wonder…

Looking at that simple arrow makes one contemplate our place in the Universe and wonder what it all means…

Maybe a couple of thoughts/suggestions: I noticed the exact orientation of the arrow could be difficult to figure at certain orientations—so, maybe it would be possible to use ARKit and make an augmented reality option where the arrow is placed within the environment?

Also, it would be cool to be able to see the speed relative to the galaxy center, or better yet show it as a velocity vector (also using AR).

Find your center, they said

I had no idea I needed this app but it turns out I NEEDED this app. It’s incredibly simple to use, and without fail it shows me the exact vector to follow in order to find the supermassive black hole in the core of the Milky Way galaxy. Hard to describe the moment of perspective and joy this brings me, but it most assuredly does.

I’m not the only one!

So hyped to have found this app (through Jason Kottke)! I’ve thought about orienting myself with the Sun/galaxy/etc., and I’m thrilled to see someone has had this same thought. I really liked the adjacent article about homecooked apps as well. It got me thinking up ideas for my own creations👍
