    Enable Saving and Loading Scenarios

    It is now possible to save and load non starship scenarios. Further work on this functionality is certainly needed, but this is a start. Please note that the scenarios are saved in your browser's local storage, so you can only access the scenarios you have saved from the same device, and browser, you saved them on.

    Add Newly Discovered Exosystems

    Added dozens of newly discovered exoplanetary systems.

    More Small Stuff

    Added planetary atmospheres, which are very much a work in progress, in addition to a couple of new exoplanet scenarios. The contact form has been temporarily been disabled because of the large amount of spam received over the past couple of weeks.

    Bunch of Small Stuff

    New high resolution textures have been added for all the planets of the solar system, Earth's moon, the Galilean moons and the dwarf planets Eris and Makemake. Since these textures take much longer to load, a loading screen has been added, as well. Moreover, light now decays according to the inverse-square law and its colour depends on which part of the spectrum most of a star's light is emitted.

    Add Button for Resetting Scenarios

    A button for resetting scenarios has been added to the bottom panel, which means that scenarios can be reset without having to reload the website.

    Add Mass Bug Fix

    The preceding update added a bug that caused the simulation to crash when you tried to add a mass to a simulation with no masses: this has now been fixed.

    Exoplanets and New Add Mass Functionality

    Six exoplanet scenarios have been added, one of which simulates a system with a grand total of three confirmed planets. Some stellar mass templates have been added, and more than that, it is now possible to choose not to use a mass template and specify the mass and radius of the mass you are adding yourself. Feedback on this feature would be much welcome, and yes, textures will be added in a future release for these custom masses!

    Exoplanets Update

    New exoplanet scenarios have been added and the exoplanet wiki has been revamped, in addition to a better model for generating the colour of a star based on its temperature.
