University of Arizona astronomers view a 170 year old event | Environment

Astronomers from the University of Arizona are getting a chance to see a 'stellar' event that occured over 170 years ago.  Sounds impossible, right?  According to the U of A, not really. 

These scientists are able to see an explosion from double-star system Eta Carinae, via an echo, kind of like when a sound wave bounces back off a canyon wall.  The original phenomenon happened when video equipment was not available, but due to this bounce-back off some space dust, the light from the explosion can be seen today.
