The Atacama Large Millimeter/submillimeter Array (ALMA) captured a massive stellar explosion from what they believe to be two colliding protostars about 500 years ago. Protostars are basically baby stars that are still gathering mass so that they can become a typical star. From the article it seems that these events are quite frequent due to the large number of them as well as their close proximity in molecular clouds. However, we rarely get such a good picture.
