Birth Stars

The Joint Astronomy Centre at the University of Hawaii will map out a star whose light started traveling the month you were born. 
Amazingly, it can take thousands to millions of years for a photon to make it from the core of a sun to the surface, depending on many factors including density.  Once at the surface, outside the dense star, it travels at the speed of light.
Put in your birthday, and you can find a star whose light started its journey about the same time you did.  Visit the sight often, because the location of the star will change as you age.
