Babylon 5 solar system bears striking resemblance to our own

 

The number of planetary systems discovered seems to grow on a daily basis, but most of them are wildly different to our own solar system. Now a team of University of Arizona researchers led by Kate Su have used NASA’s Stratospheric Observatory for Infrared Astronomy (SOFIA) flying observatory to take a closer look at a system 10.5 light years away and discovered it has a familiar general structure.


 

The star in question is Epsilon Eridani (ε Eri) in the southern hemisphere of the constellation of Eridanus. Its previous claims to fame were as the setting for the sci fi television series Babylon 5 and the disputed location of Star Trek‘s planet Vulcan. It’s also been the subject of several early studies seeking extrasolar planets and was even monitored in the 1960s by Project Ozma as a possible source of extraterrestrial intelligence.

Much of the previous work on Epsilon Eridani involved the Spitzer Space Telescope, but SOFIA is over twice the size of Spitzer, has three times the resolution, and can operate in the infrared at wavelengths between 25 and 40 microns. What this meant was that SOFIA could discern much smaller details, especially from warm materials, than before, which suggested an alternative model to the one provided by Spitzer’s data.
