Exoplanets from another galaxy spotted – take that, Kepler fatigue!


Re: Incoming pendant

I can out-pedant you: 93 billion is the diameter of the observable universe, not the radius. It wouldn't make sense to use the diameter when saying something like "X% across the observable universe", since you're by definition R distance from the edge - nothing observable can be further away than the radius. So 8% would be more accurate.

Not that you're wrong, per se.

And, as you say, still very impressive.

The wiki has a helpful section listing common misconceptions about this.
