In 1935, Albert Einstein and two colleagues, Boris Podolsky and Nathan Rosen, wrote a now-famous paper in which they addressed one particular aspect of quantum theory. Examining the prediction that particles created together (“entangled”) can somehow know what the other is doing, the physicists argued that any such parallel behavior must be due to local effects, some contamination of the experiment, rather than some sort of “spooky action at a distance.” But recent experiments, including additional ones from 2015, show that Einstein was wrong.

Remember the movie Contact, starring Jodie Foster? She contacted aliens from a famous star that in the movie was pronounced “VAY-ga.” Well, that star’s name was spelled Wega for centuries, and spoken as “WEE-ga,” meaning a falling eagle in Arabic. It evolved to be spelled Vega and spoken as “VEE-ga” in the 19th century. And it remains “VEE-ga” today. Those who Latinize it as “VAY-ga” are getting it wrong.

A supernova in our lifetimes is not impossible.

The famous star Betelgeuse is dimmer than anyone has seen it in a century.

This is the very finest test of vision in all the heavens.

Moonlight is at its brightest. Let’s celebrate that by giving it some attention during this lunation. Copernicus, a magnificent, isolated crater with terraced walls, is regarded by many as the Moon’s most handsome feature. It’s now at its best.
