Earth is not the only planet in our solar system with auroras. As the solar wind—a stream of rarefied plasma from our sun—blows through the solar system, it interacts with the magnetic fields of other planets as well as our own. Saturn’s magnetic field second only to Jupiter’s in strength. This strong magnetosphere deflects many of the solar wind’s energetic particles, but, as on Earth, some of the particles get drawn in along Saturn’s magnetic field lines. These lines converge at the poles, where the high-energy particles interact with the gases in the upper reaches of Saturn’s atmosphere. As a result, Saturn, like Earth, has impressive and colorful light displays around its poles. (Image credit: ESA/Hubble, M. Kornmesser & L. Calçada, source video; via spaceplasma)
Before there was Bioshock, Bioshock 2, and Bioshock Infinite there was System Shock. Released 20 years ago, the original Shock had a huge influence on the games industry and the Bioshock games in particular, of course.
System Shock’s one of those games that lots of descendant creations owe a huge debt to. If you’re a fan of moody, story-centric first-person experiences like Deus Ex or BioShock, then you should be watching some of System Shock’s creators play it right now.
