In this Apogee Podcast, Cosmic discusses the search for circumbinary planets orbiting eclipsing binary stars.

Things used to be so simple. Comets were snowballs from the outer Solar System, and asteroids were rocks from the inner Solar System. But now everything’s all shades of grey. Astronomers have found asteroids that behave like comets and comets that behave like asteroids.

During the same 6-night observing session as last week, Dr. Grauer determined that 14 of the 29 objects had “help” getting into weird orbits.

NEID will search for exoplanets by using the Doppler, or Radial Velocity (RV), effect. As a planet orbits its star, it exerts a tiny gravitational pull on the star, causing the star to “wobble.”

Astronomy roundup and discussion. Prepare yourself for next week Transit of Mercury.
