Another one for the Fermi Paradox list: Your planet gets dusted by the Vogons to make room for a new interstellar expressway.

Fantastic breakdown of the Fomalhaut puzzle. Nerdy fun fact: many “planet detections” around bright stars can turn out to be dust clouds from collisions, because the scattered light can mimic a point source until it expands and fades. Watching a debris disk evolve in real time is rare and so cool.

Bring on the Vera Rubin telescope, show me the probes

I think it makes sense there are a lot of collisions. They are all competing for the same Lagrange points and 'stable' orbits.

The fact we could detect objects the size of cities many light years away is astonishing.

If we can detect asteroids only a few dozen kilometers across colliding in other star systems, imagine how spectacular an actual planetary collision would be in our space telescopes. Something similar to the Earth/Theia collision.

Anton is actually the most wonderful person. We are so lucky to have him

That's what happens when you name a planet after a Great Old One.
