Observations point to potential discovery of a new Solar System

epsilon eridani Astronomers are excited by the possible discovery of three planets circulating Epsilon Eridani, one of the nine closest stars to us. The findings of NASA’s Spitzer Space Telescope are consistent with the presence of three planets around the star. This newly reported solar system is quite interesting as it resembles our own system as it may have been many years ago. (Our system is nearly five times older than that of Epsilon Eridani.) The similarities of the two systems include the following:

One of the three planets, a gas giant, was discovered in 2000 by Barbara McArthur, an astronomer at the University of Texas in Austin – confirmed two years ago by the Hubble Space Telescope. It is hoped that astronomers may have a nice view of this solar system in the years to come with the development of higher powered telescopes.

Dana Backman, of the SETI Institute in Mountain View, California is the lead author of the report detailing the discovery which is to be published next year in The Astrophysical Journal.
