We've discovered a new class of object, and we need to use Spitzer to measure the infrared spectra of a lot more of these objects to learn how unique they really are.

These planetary systems, if they do form and exist, are short lived because these massive stars explode as supernovae. So it's amazing that the raw material for planets could be found in such a hostile environment.

Our data suggest that the planet-forming process may be hardier than previously believed, occurring around even the most massive stars.

On the other hand, we can't really predict the future of these systems with much certainty.

You cannot measure the absolute speeds of the stars, but you can measure their relative speeds along the line of sight, because if a star is moving toward us its light is shifted to shorter wave lengths, and if it is moving away from us its light is shifted to longer wave lengths.

There are definitely intriguing guys in this year's class.
