The evolution of Saturn's radiation belts modulated by changes in radial diffusion
Krupp, N.; Roussos, E.; Paranicas, C. +2 more
Globally magnetized planets, such as the Earth1 and Saturn2, are surrounded by radiation belts of protons and electrons with kinetic energies well into the million electronvolt range. The Earth's proton belt is supplied locally from galactic cosmic rays interacting with the atmosphere3, as well as from slow inward …
The Galaxy's veil of excited hydrogen
Zaritsky, Dennis; Zhang, Huanian
Many of the baryons in our Galaxy probably lie outside the well-known disk and bulge components. Despite a wealth of evidence for the presence of some gas in galactic halos—including absorption line systems in the spectra of quasars, high-velocity neutral hydrogen clouds in our Galaxy halo, line-emitting ionized hydrogen originating from galactic …
Gamma-ray observatory INTEGRAL reloaded
van den Heuvel, Edward P. J.
The scientific aims of the European Space Agency's International Gamma-Ray Astrophysics Laboratory are considerably extended because of its unique capability to identify electromagnetic counterparts to sources of gravitational waves and ultra-high-energy neutrinos.
Titan: Bubbles in focus
Hanley, Jennifer
The seabed of Ligeia Mare, a hydrocarbon sea at the north pole of Titan, may be a favourable place for the separation of nitrogen and the creation of bubbles that then buoyantly rise to the sea's surface.
Huygens and Titan's methane cycle

Comets: Exposing the icy interior of 67P
Delbo, Marco
Images from ESA's Rosetta mission show, in real time, the processes that sculpt the surface of a comet, which is revealed to have a pristine icy interior surrounded by an evolved surface.
