About LS

langitselatan is an astronomy communication and educator media in Indonesia. Staff communicate astronomy with the public through online media, star parties, telescope training, and hands-on activities. langitselatan also conducts research in astronomy, etnoastronomy, and archeoastronomy.

langitselatan means southern sky, has been chosen as our name because we based in Bandung about 6 degree under the equator and sharing the southern sky.  The constellations and stars in the southern sky are unique and different from the constellation you see in northern sky

We choose Centaurus as our logo, because this is the southern sky constellation along with southern crux. Centaurus the Centaurs, representing wisdom as we hope that we will share scientific wisdom to the people.
