Episode notes

There are apparently planets that don't have any stars, that are just in between the ston. How did this thing get orphaned from its star? Orr, or do we not understand star form and well enough to understand that this might be one of the possible outcomes of making stars? Well, i think because a lot of people don't have the background knowledge about star formation, et cetera. I would personally put a large credence that these planets used to be associated with stars at the moment of their formation, somehow got kicked down.

Recent years have seen a revolution in the study of exoplanets, planets that orbit stars other than the Sun (or don’t orbit stars at all). After a few tentative detections in the 1990s, dedicated instruments in the 2000s have now pushed the number of known exoplanets into the thousands, enough to begin to categorize their distribution and properties. Today’s guest is John Asher Johnson, one of the leaders in this field. We talk about the various different ways that exoplanets can be detected, what we know about them know, and what might happen in the future.
