The space between the planets is far from empty. It contains: electromagnetic radiation (photons); hot plasma (electrons, protons and other ions) a.k.a. the solar wind ; cosmic rays; microscopic dust particles; and magnetic fields (primarily the Sun's). While the Sun 's radiation is obvious, the other components of the interplanetary medium were not discovered until very recently. ... Except near some of the planets, interplanetary space is filled with the Sun's magnetic field. ... Sun .. ...

Next: Selecting the backup tool Up: Backups Previous: On the importance of . The most important decision regarding backups is the choice of backup medium. ... Cost is important, since you should preferably have several times more backup storage than what you need for the data. A cheap medium is usually a must. ... A hard disk is typically very reliable, but as a backup medium it is not very reliable, if it is in the same computer as the disk you are backing up. ...

The interstellar medium is the material that lies between the stars in a galaxy . This material can exist in several phases with a wide range in temperature (from tens of degrees to tens of millions of degrees Kelvin). In the coldest regions the material consists of molecular gas and dust; in the hottest regions the material is almost completely ionized. The Role of the Interstellar Magnetic Field A. Goodman .

... Numerical simulations of cosmic structure formation and evolution are now suggesting that a galaxy-cosmic web connection might be the key ingredient for regulating galaxy evolution, including the morphological type, star formation history and gas content. ... This is why the most basic questions remain 50 years after the first attempts to detect intergalactic gas: Is the intergalactic medium driving star formation? ...
