Publisher: arXiv 2011
Number of pages: 43
We briefly review sources of cosmic rays, their composition and spectra as well as their propagation in the galactic and extragalactic magnetic fields, both regular and fluctuating. A special attention is paid to the recent results of the X-ray and gamma-ray observations that shed light on the origin of the galactic cosmic rays and the challenging results of Pierre Auger Observatory on the ultra high energy cosmic rays.

Flattened disks of cool dust and gas are found around almost all low mass stars shortly after their birth. This review addresses observations of the outer parts of protoplanetary disks with a focus on recent infrared and (sub-)millimeter results.

This comprehensive review summarizes our current understanding of the evolution of gas, solids and molecular ices in protoplanetary disks. Key findings related to disk physics and chemistry, both observationally and theoretically, are highlighted.

The main purpose of this volume is to reproduce and make available for study, the larger and more interesting nebulae and clusters, sixty-eight in number. James Edward Keeler was the director of the Lick observatory 1898 - 1900.
