Why haven't we found evidence of advanced aliens? It could be that they've outsourced cosmic exploration to superintelligent AI, a new paper suggests.

With new technologies come new opportunities. And that is especially true in astronomy - with every new advanced telescope we have the potential to

We've reported on all kinds of wacky ideas for capturing and deorbiting space debris safely.

We've talked plenty of times here about the infeasibility of launching a mirror big enough to directly image exoplanets using current rocket fairings
