Sounds like they have found the Fleet of Worlds. This is really bad news.

That, Oumuamua, the Great Daylight Fireball of 1972 and Miranda’s strip-mined appearance all spook me.

The best news this week concerns a new alloy:

The claim is that this steel is good from -196 Celsius to 600 degrees Celsius.

In the comments at the site referenced in the first comment above, the question is raised whether a multi-star, multi-planet system could be gravitationally stable. My conjecture is… probably not, but it probably doesn’t matter, if advanced intelligences have enough time to arise in it.

This is because a powerful intelligence (biological, assisted by AI) could certainly derive and execute the relatively minor adjustments to planetary orbits required to maintain stability.
