The origin of the ultra-high energy cosmic-rays (UHECRs) is still unknown. I will show that the observational data on the spectrum and composition can be explained by a generic model having one Galactic component and one extragalactic component. I will also discuss the origin of the UHECR dipole anisotropy recently reported by the Pierre Auger Observatory.

The message of the Kepler space mission is this: super-Earths abound in the universe. These are planets 1--4 Earth radii and 2--20 Earth masses in size, and composed of solids and gas in proportions of 100:1 by mass.
