Star Gazing from your Desktop

Like most kids I dreamt of becoming an astronaut when I was little. When I realized that it is far from becoming a reality (like in a country where PAGASA is the closest space program), I gave it up early but kept the respectful wonder to the skies above my head.

 If you're still eager like me, to explore the night sky and become an amateur astronomer, you'll need to overcome one of astronomy's biggest hurdles — learning to identify the stars and constellations. After all, you won't be able to locate the Orion Nebula if you can't find the constellation of Orion, which is, to most the easy to spot together with Ursa Major(The Big Dipper is not a constellation but rather of an asterism in Ursa Major  ).

Well here's what is probably the most helpful tool for beginners learning to read star maps.

Stellarium is a free open source planetarium for your computer. It shows a realistic sky in 3D, just like what you see with the naked eye, binoculars or a telescope. It is being used in planetarium projectors.





You can set your coordinates(Manila Coordinates: 14°35′N 120°58′E) and local time to match the actual star positions above your head.



It also has a convenient search function which will lead you to planets, galaxies, nebuleas, and all other space objects.
