APOD 2.8

100 Million Stars in the Andromeda Galaxy

The image you see above is considered the largest image ever taken by the Hubble Space Telescope.  It features the spiral of the Andromeda Galaxy and the millions of stars within.  Despite the enormity of what is pictured, only one third of the galaxy is shown(!). Additionally, the estimated 100 million stars that are visible in the picture are only foreground stars! And although it's deceiving, most of the bright stars that you see in this image are actually from the Milky Way.  

Something on my bucket list is to view galaxies like this someday. 

Godspeed,
Melanie
