Finally I can play thanks to v2.02, if only on Solo. Wow, this is truly stunning! Here's hoping v2.03 fixes even more stuff.

Nice! Not as pretty as the early concepts but more practical - looks like the Frontier version but bigger, which is no bad thing :)

Where are the fleets of H2 fuel tankers that supply all the stations? Presumably they will need escorts and scoop ships too. Sounds like a full-time job.

Coming in on Super-cruise, planetary disks are in the wish list, hope they look like this .....
 
Planetary Genesis
ALMA has obtained its most detailed image yet showing the structure of the disc around HL Tau, a million-year-old Sun-like star located approximately 450 light-years from Earth in the constellation of Taurus. The image exceeds all expectations and reveals a series of concentric and bright rings, separated by gaps.

Stars like HL Tau and our own Sun form within clouds of gas and dust that collapse under gravity. Over time, the surrounding dust particles stick together, growing into sand, pebbles, and larger-size rocks, which eventually settle into a thin disc where asteroids, comets, and planets form. Once these planetary bodies acquire enough mass, they dramatically reshape the structure of the disc, fashioning rings and gaps as the planets sweep their orbits clear of debris and shepherd dust and gas into tighter and more confined zones.

The investigation of these protoplanetary discs is essential to our understanding of how Earth formed in the Solar System. Observing the first stages of planet formation around HL Tauri may show us how our own planetary system may have looked more than four billion years ago, when it formed.

Another graphics tweak required!
 
A Darker Edge

When you look at an image of the Sun, you might notice that it’s edge appears slightly dimmer than its center. This is an effect known as limb darkening, and its actually quite useful to astronomers.

It all has to do with our line of sight to the Sun. When we view the middle of the Sun, we are looking directly into the Sun. When we view the edge of the Sun, we see light coming at a glancing edge through the Sun. Because of the density of the Sun’s atmosphere, the light we observe always comes from about the same distance through the upper layer of the Sun. So in the middle we see to a certain depth into the Sun, but on the edge we see light from a more shallow depth. The depth we observe can be determined by simple geometry, so by looking across the Sun, we are actually seeing to a varying depth at different points.

The reason the Sun appears dimmer near the edge is because the Sun gets hotter the deeper you go. This makes sense, but with limb darkening we can prove it. In fact, with detailed measurements of limb darkening, we can determine just how the temperature of the Sun varies with depth.

A similar effect occurs with other stars. There are only a few stars where we can resolve this directly, but Betelgeuse is a good example. In the case of Betelgeuse, the darkened region is much wider than that of the Sun, which indicates Betelgeuse has a much thicker atmosphere. This is typical of red giant stars, which, while larger than the Sun, are much cooler and less dense.

That's amazing! I hope they continually tweak the game to reflect findings like this.
