(DESCRIPTION) 
 Text, Did You Know? Images of the Milky Way 


Spirals around an elongated golden circle. Text, We can only photograph the Milky Way from the inside. Images of our galaxy are illustrations, not photographs. 


Based on observations of other galaxies and the motions of the stars in our galaxy, the Milky Way's overall appearance resembles this model. Illustration of the Milky Way. 


We would have to send a spacecraft far outside the Milky Way to take a complete "portrait" of the galaxy. 


It would take billions of years to arrive and hundreds of thousands more for the image to return to Earth. 


We can view the Milky Way from our position inside it, whether from Earth with our own eyes or through telescopes. 


Researchers also apply information about other galaxies to inform models of our own Milky Way, refining our understanding of the galaxy. Image of the Milky Way. APEX Telescope.
