A sprinkling of stars in the clear night sky with little clouds are now difficult to find. Especially in urban areas by the number of fluorescent light from street lights and tall buildings make the black sky was not black as in rural outposts. Scientists and astronomers to map the celestial objects, object-object in three dimensional space leveled at the paper so it is difficult to understand. No wonder many people are confused reading the map of the city is relatively flat and static, let alone read a map of the sky that could be considered the surface of the half sphere seen from its center and is dynamic, always moving.
Secondary schools teach basic knowledge about it, like the concept of horizon, azimuth, rotation of the earth's orbit, orbit ekliptikal, eclipses, solar system and constellations. Sometimes the teacher's lessons are peppered with the necessity to be able to make a perfect circle on the board without the auxiliary term. Outside the school, the world of entertainment offered astrological forecast trash. Not important, but sometimes crowded talk about, sometimes matched and matched, as if the prophecy must be appropriate to ourselves. Even the owner attribute of the zodiac is not necessarily know where the star constellations in the sky.
Sky map is now more visual in the planetarium simulation, a map of the sky in half a ball screen. Sitting on his back rather watch how the planets and stars mapped. When the map projection is moved too fast to make us feel like spinning about falling. In Indonesia, perhaps only in the complex Planetarium Jakarta Taman Ismail Marzuki, you can visit.
Technological developments now allow us to enjoy the planetarium at home via computer screens. Even the application is available free, no need to pay licensing, live download, set the location of the house / your city, and enjoy. Some astronomy application is less attractive to laymen, perhaps because too specific or too scientific, or just simply looks too rigid graph. One application planetarium is very interesting and good is Stellarium.
Stellarium When first opened, we enter the home or the geographical position of our city, and Stellarium will display the sky in accordance with the computer clock. If your evening will get a black sky full of stars, if your monitor screen during the day a little dazzled by sunlight luminescence. By using your mouse to live motion toward the sky where you want to see. You can choose the display mode, could be in perspective mode as our eyes look at the horizon and the sky directly, can stereographic, can even display in the form of fish eyes.
With the mouse-wheel button you can go to the object of observation with magnification, information, names and other details will be visible in the upper left corner, there is even a dynamic display objects such as distance, because the object being observed moving realtime in accordance with reality.
Than 120,000 objects are mapped with this application does not all have pictures. Several important objects is accompanied by a giant telescope images, making objects that we observe more realistic, such as observing the planet Saturn with the enlargement we will see Saturn rotates, seen from a moving surface texture.
Not only is the object of the sky in the form of planets and stars, accompanied Stellarium display lighting and atmospheric conditions. For example, during the late afternoon sunset, the sky would flush yellowish Stellarium. In addition to the horizon along a compass direction, as well as areas of sky can be displayed grid azimuth, the constellation of stars, nebulae, constellations and artistic picture. Some view the horizon can be selected, whether at sea or in the meadow.
Needs computer specs for this application is not too high.
It is a freeware so you can download it without buy it.
