Insight B System - Moons of the sixth planet

Here we have a few views of the system’s sixth planet viewed from the surfaces of the three inner-most moons.

The heliosphere is the bubble-like region of space dominated by the Sun, which extends far beyond the orbit of Pluto. Plasma “blown” out from the Sun, known as the solar wind, creates and maintains this bubble against the outside pressure of the interstellar medium, the hydrogen and helium gas that permeates the Milky Way Galaxy. The solar wind flows outward from the Sun until encountering the termination shock, where motion slows abruptly. The Voyager spacecraft have explored the outer reaches of the heliosphere, passing through the shock and entering the heliosheath, a transitional region which is in turn bounded by the outermost edge of the heliosphere, called the heliopause. The shape of the heliosphere is controlled by the interstellar medium through which it is traveling, as well as the Sun and is not perfectly spherical. The limited data available and unexplored nature of these structures have resulted in many theories. The word “heliosphere” is said to have been coined by Alexander J. Dessler, who is credited with first use of the word in the scientific literature.

On September 12, 2013, NASA announced that Voyager 1 left the heliopause on August 25, 2012, when it measured a sudden increase in plasma density of about forty times. Because the heliopause marks one boundary between the Sun’s solar wind and the rest of the galaxy, a spacecraft such as Voyager 1 which has departed the heliosphere, can be said to have reached interstellar space. source

Lunar Rings

Pictures of the Day - October 21, 2018

Normally, giant planets are the ones with rings, but in some situations a moon of a gas giant can have its own rings. Here we come across such a satellite.

O’Srius System - Post 3 (Stunning World)

Here we come across the smaller component of a double planetary system, being the 9 and 10th planets from the star. This planet is by far the most visually stunning world I have come across in the 6 months of playing space engine.

The world is roughly the same size as Earth, but only 0.58 times the mass. The surface is covered in liquid nitrogen oceans and nitrogen ice-caps. The planet has a surface temperature of 68 K or -337 °F. The atmosphere is composed of nitrogen and argon with a surface pressure of 0.095 atmospheres. The surface has a nitrogen cycle, much the same as Earth has a water cycle.

Cratered surface of a small burnt dwarf planet. Fissures run through the surface from the core cooling and the crust shrinking.

For scientists watching the Red Planet from our orbiters, the past month has been a windfall. “Global” dust storms, where a runaway series of storms create a dust cloud so large they envelop the planet, only appear every six to eight years (that’s 3-4 Mars years). Scientists still don’t understand why or how exactly these storms form and evolve.
