“We are stardust, we are golden,
We are billion year old carbon,
And we got to get ourselves back to the garden.” –Crosby, Stills, Nash & Young
When Charles Messier first began cataloguing nebulae, even globular clusters, just a few tens of thousands of light years distant, weren’t resolvable into individual stars. But thanks to the Hubble Space Telescope, we can see individual stars in other galaxies many millions of light years away.
In a series of images taken from 2004-2007, well outside the region of the more-famous Panchromatic Hubble Andromeda Treasury (PHAT), images of Andromeda’s outer disk, halo and stellar stream were acquired, giving us a glimpse of not only its Sun-like stars and dimmer variables, but of hundreds of background galaxies lying in the abyss of deep space beyond.
