Staring Into Galactic Infinity
The European Space Organization (ESO) has just released the stunning photo above. At first glance, its just another fine piece of star porn, beautiful little glowing dots and clouds, like so many others whose images we have captured in our quest to catalogue the observable universe.
But this one is special.
This is a nine-gigapixel image was taken using a telescope that looks into the infrared, allowing us to see through the dusty galactic arms. The view is of the galactic center of the Milky Way, our home. That means somewhere in the glowing center lies a black hole, and we are here, rotating around it. The photo marks the largest catalogue of Milky Way stars ever assembled.
If you made counting all of the 84 million objects so far identified in this picture a full-time job, counting 16 hours per day at a comfortable pace, it would take you somewhere in the neighborhood of 20 years to finish. If it were printed at book resolution, that image would be 9 meters tall and 7 meters wide.
And this is less than 1% of the whole sky. In just our own galaxy.
