3D Galaxy Map

探索外太空遙遠的外星世界和結構

Explore the galaxy in a stunning three dimensional map based on NASA's artistic impression of the Milky Way galactic structure. Photos are taken by NASA spacecraft and ground based telescopes like Hubble Space Telescope, Chandra X-Ray, Herschel Space Observatory and the Spitzer Space Telescope.

From the outskirts of the galaxy, in the Norma-Outer spiral arm to the galactic center's supermassive black hole Sagittarius A*, discover a galaxy full of amazing facts.

Ever wondered how far from Earth are the stars you see in the night sky? Or how far or close they are to each other? Now you can visualize those distances in 3D with a star map divided into 10 parsec sectors (cubes) or 32.62 light years, for an easier observation. Sector (0 ,0 ,0) is our home sector and Sol is the Solar System.

Take a thrilling ride through space and visit strange new alien star systems and black holes. Find out where our Sun - the Solar System - is located in the Milky Way galaxy!

Explore space and get a little closer to our wonderful universe with this awesome astronomy app!

This interactive 3D map is excellent for teachers to use for instruction, and it is a great resource for students to explore the Milky Way galaxy and space as they learn more about the universe we live in.
