A suite of studies published in the Astrophysical Journal provide a first look at the constituents of the interstellar medium, the matter between star systems, and how they interact with our heliosphere.

New studies has shown that vulcanic activity on the Jovian moon Io, influenes Jupiters magnetic field, and afre dicerectly responsible for changes in the superplanets aruroral activities.

Hydrogen molecules may act as a kind of energy sink that strengthens the magnetic grip that causes sunspots, according to scientists from Hawaii and New Mexico using a new infrared instrument on an old telescope.
