Answering a tricky question with the KStars desktop planetarium package

Filed under
Software
HowTos

In an earlier phase of my life, I worked as a professional astronomer, and I've loved space and astronomy since before I could pronounce the words. So naturally, I've gotten a lot of personal pleasure from the free software astronomy tools that are included in my Debian GNU/Linux system. But ironically, I haven't written about them much. Recently, though, I was asked a question which I used KStars to answer, so this is a good chance to talk about how to use it.

KStars is a "planetarium" software for KDE. This means that it is designed to show you what the night sky will look like on a particular night at a particular time in a particular location on the Earth. As you probably know, we are living on a rotating spherical Earth, tilted about 23 degrees from the plane of its orbit around the Sun. And of course, the other seven major planets, five dwarf planets, and zillion minor planets in our solar system are doing much the same.

Android Marshmallow on PC Falls Flat

The Android-x86 Project eventually may become a viable operating system alternative for your desktop and laptops computers, but it's not there yet. You will have to wait a while for the developers to fix a number of failures with the latest release upgrading Android-x86 to Marshmallow 6.0.1. The developers late this summer released the first stable version of Android-x86 6.0, codenamed "Marshmallow." Android-x86 lets you run the Android OS with the Google Chrome browser on your desktop and laptop computers, rather than buying one of the qualified Chromebooks with the Google Play Store features bolted on.
