Radio Waves Used to Uncover Oldest Galaxies Yet

 Windows to the past, stars can unveil the history of our universe, currently estimated to be 14 billion years old. The farther away the star, the older it is -- and the oldest stars are

the most difficult to detect. Current telescopes can only

see galaxies about 700 million years old, and only when the

galaxy is unusually large or as the result of a big event like a

stellar explosion.
