Das NASA Weltraumteleskop Spitzer hat im Sonnensystem Epsilon Eridani zwei Asteroidengürtel entdeckt. Das System ist unser nächster ‚Nachbar‘, wobei die Reise länger dauern wird bei 10,5 Lichtjahren.

„This system probably looks a lot like ours did when life first took root on Earth,“ said Dana Backman, an astronomer at the SETI Institute, in Mountain View, Calif., and outreach director for NASA’s Sofia mission. „The main difference we know of so far is that it has an additional ring of leftover planet construction material.“ Backman is lead author of a paper about the findings to appear Jan. 10 in the Astrophysical Journal.
