Release 1.2.0 opens the black hole at the centre of the galaxy.
Black hole expeditions
Research the Charon, give it an escort, and send it into the black hole. The fleet stays inside as long as you dare. Every hour it may find resources for its hold, and every hour some escorts may not make it back. The longer it stays, the richer the finds and the higher the risk. Expeditions are built to last days, not hours.
Recall it whenever you like. Fuel for the round trip is paid up front, so a recall never strands it. Lose the last escort, though, and the Charon goes down with everything it carries.
Ancient ships
Long stays turn up ancient ships: the Phanes, the Aion and the Ananke. Nobody can build them. While the fleet is inside they are held apart from it, safe unless every escort is lost, and they come home with it to serve like any other ship.
A tab of its own
Expeditions have their own Expedition tab on the Fleet screen. It shows how long the fleet has been inside, the chance of losing each escort, the hold, and a log of every hour at its real time. Choosing the Expedition mission when sending a fleet now picks the black hole for you.
System messages open again
The System conversation in Messages could not be opened, so its notices stayed unread. It opens now, and reading it clears the badge.
