ESOcast 139: Why Astronomers Want to Use ALMA — ALMA and the Cold Interstellar Clouds

27 november 2017

The Universe isn’t empty space — it’s full of dust! Some regions are in fact very, very dusty. New baby stars, for example, are surrounded by a disc of dust that feeds material to the young star, causing it to grow. This vital stage in a star’s young life must be closely studied in order to better understand stellar evolution. However, seeing through dust is difficult for many telescopes. That is where ALMA comes in.

ESOcast 139 shows how the unique observational capabilities of ALMA allows astronomers to learn about otherwise hidden objects in our Universe.
