Here’s an
update on recent KDE application development on KDE.news:

KStars is probably the most feature-rich free astronomy software around and the 3.5.9
release adds some exciting new features.

HiPS (Hierarchical Progressive Surveys) is a technology that provides
progressive high resolution images of the sky at different zoom
levels. KStars fully supports online HiPS where data is downloaded from
online servers and cached to be displayed on the Sky Map.
