ESOcast 79: 20 Years of Exoplanets

(Before It's News)

Not a single confirmed planet outside the Solar System had been detected before the year 1990. But, remarkably, we now know of thousands and have studied many in surprising detail. This ESOcast takes a look at how ESO’s observatories in Chile have been at the forefront of this enormous expansion in knowledge, and how their state-of-the-art instruments are continuing to discover and study the extraordinary diversity of exoplanets.
