The lunar cycle and the solar cycle don't naturally sync up, so different civilizations have tried different ways of forcing them into harmony.
At the end of its life, our Sun could end up as a crystal—and physicists now have observational evidence to back up that theory.
For the first time, researchers observed a stellar death before their eyes – a supernova and a forming black hole or a neutron star

NASA got 2019 started off with a bang.
The only nonfunctional cargo on New Horizons is a handful of context-free symbolic items that would be, to put it mildly, a challenge for any ET to understand.
That's our best stuff for today. Great job! Read more
