A cold ice-world with a thick nitrogen atmosphere backlit against a blue B-type sun. The star is so bright that all objects, even some asteroids reflect enough light to be visible orbiting close to the star. The comet-looking object is not a comet, but a planet getting its atmosphere burnt away by the sun.

Planets in our own solar system have a wide range of properties. They are distinguished by two basic properties, their size and their orbit. The size determines if the planet can have a life-sustaining atmosphere. The orbit affects the surface temperature and whether there could be liquid water on the planet’s surface.
Hot Jupiters are a class of gas giant exoplanets that are inferred to be physically similar to Jupiter but that have very short orbital period (P<10 days). The close proximity to their stars and high surface-atmosphere temperatures resulted in the moniker “hot Jupiters”.
Hot Jupiters are the easiest extrasolar planets to detect via the radial-velocity method, because the oscillations they induce in their parent stars’ motion are relatively large and rapid compared to those of other known types of planets.
One of the best-known hot Jupiters is 51 Pegasi b. Discovered in 1995, it was the first extrasolar planet found orbiting a Sun-like star. 51 Pegasi b has an orbital period of about 4 days.
There are two general schools of thought regarding the origin of hot Jupiters: formation at a distance followed by inward migration and in-situ formation at the distances at which they’re currently observed. The prevalent view is migration.
Migration
In the migration hypothesis, a hot Jupiter forms beyond the frost line, from rock, ice, and gases via the core accretion method of planetary formation. The planet then migrates inwards to the star where it eventually forms a stable orbit. The planet may have migrated inwar.
In situ
Instead of being gas giants that migrated inward, in an alternate hypothesis the cores of the hot Jupiters began as more common super-Earths which accreted their gas envelopes at their current locations, becoming gas giants in situ. The super-Earths providing the cores in this hypothesis could have formed either in situ or at greater distances and have undergone migration before acquiring their gas envelopes.

From this point forward, all Space Engine posts on my pillowfort and my Tumblr page will be the same.
Here we come across a small green-colored ice giant with an active atmosphere. This planet orbits a binary pair of red dwarfs and has a small yet well structured ring system. Additionally, a system of 13 natural satellites orbit the planet, including two of which that are large enough to be rounded by their own gravity. Like Uranus, this planet also orbits on it's side.

Tempus System - First Round of Pictures
I’ve decided to showcase another system, and here are the pics of a system in the Large Magellanic Cloud Galaxy I am calling the Tempus System

First pictures from the M59 galaxy. Here I come across a 7 planet system orbiting an orange giant. All the planets in this system are experiencing the effects of the expanding sun, and orbit relatively close to the sun. The outer-most ice giant orbits just 3.62 AU from the sun.

I just unfortunately found out that Tumblr does not allow posts with links in them to show up on searches. This is very problematic for me since I like posting 4K resolution pics on here. Anyone have any suggestions on how to keep Tumblr from reducing image sizes so I do not have to add links to my posts?

Its been a while since I showcased an entire star system on here, so the next several sets of pictures will be all the planets in this one system that I am going to name the “Insight System” after the newest Mars lander. Many more picture to come.
Above is a preview pic of the system. This is a binary system, so the planet’s night sides are all faintly illuminated.
