  Epsilon Eridani
Epsilon Eridani has been the target of intense scrutiny by SETI projects, including the first, Project Ozma.
Moreover, Epsilon Eri provides a window into what conditions may have been like in the neighborhood of the Sun at a time when life was first beginning to emerge on the young Earth.
The presence of Epsilon Eridani C was disclosed by researchers at the University of Rochester using a new technique that does not use direct light from the star, but rather light radiating from the dust surrounding it.

Epsilon Eridani is clearly visible to the naked eye, in the constellation Eridanus (the River), which stretches from the foot of Orion (near the bright star Rigel) to the 9th brightest star in the sky, the southerly Achernar (barely visible from the USA and Europe).
Epsilon Eridani is believed to be only 500 million years to 1 billion years old; our Sun is estimated to be 4.5 billion years old, and its inner region is believed to have looked very similar at that age.
