Atlas path: find an anomaly??

Can anyone please point me in the right direction

I've not long started the game and I'm in mission atlas path: find an anomaly.

I've warped to a system and the mission indicator shows me to go into a space station. But in there it's just a regular station with traders I'm not sure what I need to do. How do I find an anomaly there?

On the galaxy map I'm a good few systems away from the atlas interface. Am I just supposed t grind to build enough warp cells to get there ? What's his sub mission about find an anomaly I literally can't find anything about it in this space station ?
