150 LY away? We have no HOPE of ever getting there to verify. At least it’s conceivable that we might someday send a probe to Proxima Centauri. It’d take centuries to get there, but at least it’s possible. 150 LY away? No.
Just send an FTL probe.
The only difference is distance. A probe would get there, but maybe a millenium or two later. Transmitting the info back to Earth would take another 150 years, assuming there were any people here that would remember to listen for it..................................Assuming , of course it didn’t hit anything on the way.......................
