There’s a tantalizing sign of a habitable-zone planet in Alpha Centauri

From TechnologyReview.com:
"An international team of astronomers has found signs that a habitable planet may be lurking in Alpha Centauri, a binary star system a mere 4.37 light-years away. It could be one of the closest habitable planet prospects to date, although it’s probably not much like Earth if it exists."

Another nit to pick is that "chronograph" is not the word for the the instrument which is a "coronagraph".

That would be great if you can do this type of measurements with your wristwatch. :lol:
