Well, it would depend on what you term 'significant' @austinhopper.

Are you expecting 'significant' alien contact? Lolz...

I believe nothing significant to the extent of troubling the earth and human perception of the galaxy has yet been discovered.

It was launched late last year, and has done a few rounds of missions, detecting unique sounds deep in space....the scientists are on course to interpret the signals received.

Time would tell, if the discoveries would turn out significant.

Thanks for visiting @austinhopper
