: Introduced procedural volumetric raymarched nebulae and volumetric rings.

Mountains and terrain silhouettes load faster and are more accurate, significantly improving the experience of landing on and flying over planets. 2. Physically-Based Rendering (PBR)

If you choose the free legacy version over the paid Steam version, here are the main features introduced in the 0.990 update that you will miss out on:

Websites offering "free updated cracked versions" or "Space Engine 0.990 full version free download" often pack these files with malware, adware, or crypto-miners.

Space Engine is developed by a very small team (largely a single developer originally). Downloading pirated versions not only hurts the project's future but often contains malware, viruses, or bloatware. If you enjoy the simulator, supporting the developers ensures we get future updates like 0.991 and beyond.

Version 0.990 was a landmark release. Released in June 2019, it marked the last major "free" version before the developers (Cosmographic Software) moved to a paid model on Steam to fund continued development.

The 0.990 update completely overhauled the simulator. It justified the transition to a premium software.

With Space Engine, users can create their own planets, moons, asteroids, and comets, and populate them with a wide range of celestial objects, from stars and galaxies to nebulae and black holes. The software also features a robust physics engine, allowing users to simulate realistic astronomical phenomena, such as planetary orbits, eclipses, and supernovae.

The updates surrounding the 0.9.9.0 and subsequent versions focus heavily on bringing the universe to life with better lighting, sharper textures, and improved planetary generation. While the 0.9.8.0 version brought life-simulated plants, new celestial objects, and reworked black holes, the 0.9.9.0 iteration is designed to take the visual experience to the next level. 1. Enhanced Visuals and Rendering

However, remember that support for 0.990 ended in 2019. You will not get new exoplanets (like those from JWST), bug fixes, or modern graphics features. The paid Steam version is where SpaceEngine lives now.

The official site also hosts free high-resolution texture packs for the Solar System (Earth, Mars, Moon) compatible with the free version.

Ensure your PC has a dedicated GPU with at least 2GB of VRAM (4GB+ recommended) to handle the 0.990 engine.
